A identificação pessoal através da análise da textura da íris é um método de identificação biométrico de grande eficiência. Algoritmos e técnicas foram desenvolvidos levando-se em consideração as características de textura da imagem da íris do olho humano. No entanto, essas características por serem estáticas são também susceptíveis a fraudes, ou seja, uma foto pode substituir a íris em análise. Por isso, este trabalho propõe um método para extrair as características de textura da íris durante a contração e dilatação da pupila, além das próprias características dinâmicas de contração e dilatação. Para isso foi desenvolvido um novo sistema de aquisição da imagem utilizando iluminação NIR (Near Infra-Red) e levando-se em conta o reflexo consensual dos olhos. As características são medidas de acordo com um padrão dinâmico de iluminação controlado pelo programa. Com isso, é possível aumentar a segurança de dispositivos de reconhecimento biométrico de pessoas através da íris, pois, somente íris vivas podem ser utilizadas. Os resultados mostram um índice de precisão significativo na capacidade de discriminação destas características. / The personal identification by iris texture analysis is a highly effective biometric identification method. Some algorithms and techniques were developed, taking into consideration the texture features of the iris image in the human eye. Nonetheless, such features, due to the fact that they are static, are also susceptible to fraud. That is, a picture can replace the iris in an analysis. For that reason, this work proposes a method for extracting texture features of the iris during the pupil contraction and dilation, in addition to the dynamic contraction and dilation features themselves. Therefore, it was developed a new image acquisition system through NIR (Near Infra-Red) illumination, considering the consensual reflex of the eyes. Features are measured according to a dynamic illumination standard controlled by the software and are afterwards selected by means of data mining. Then it is possible to increase the safety in the biometric recognition devices of people through their iris, since only living irises can be utilized. Results show a significant precision index in determining such features.

Em casos de inexecução de tais contratos surgem inúmeros desdobramentos. A partir da observação de dificuldades práticas para resolução de impasses decorrentes da inexecução de tais contratos o presente trabalho traz uma abordagem teórica dos contratos administrativos e especificamente dos contratos firmados entre entes do Poder Público para, a partir desta análise, abordar algumas medidas que podem contribuir para a devida execução e para prevenção e resolução de conflitos decorrentes de tais contratos. Uma das medidas propostas é a aplicação de instrumentos consensuais, tais como, a arbitragem, a mediação, a conciliação e a transação administrativa para prevenção e resolução de conflitos contratuais como forma de se primar pela eficiência e evitar a litigância intragovernamental. Diante da relevância e complexidade do tema, para além de apontar possíveis soluções, o objetivo da presente abordagem é trazer o estado do desenvolvimento da matéria no Brasil e destacar a importância de sua criteriosa abordagem na doutrina, legislação e jurisprudência.

Orientador: Rosangela da Silva Laurentiz / Resumo: O estudo sobre o uso de plantas e metabolitos secundários tem sido uma das alternativas mais estudadas nos últimos anos como forma de controlar a parasitose em ovinos provocada principalmente pelo nematoide Haemonchus contortus. A Piper cubeba é uma pimenta asiática que apresenta uma série de propriedades biológicas, incluindo atividade antiparasitária, sendo essa atividade, muitas vezes atribuida às lignanas cubebina, hinoquinina e diidrocubebina, que estão presentes na planta em maior concentração. Estudos in vitro com o extrato da Piper cubeba e com as lignanas cubebina, dihidrocubebina e hinoquinina demonstraram que esses compostos apresentam importante ação contra os vários estágios do desenvolvimento de vida do nematoide Haemonchus contortus, sendo a hinoquinina a mais eficaz (CE50 = 68 μg / mL contra ovos, CE50 < 35 μg / mL contra o estágio L1 e CE50 = 0.34 μg / mL contra o estágio L3). Devido à relevância desses resultados foram então realizados estudos de docking molecular com essas lignanas com o objetivo de avaliar a ação desses compostos com as proteínas fosfoetanolamina metil transferase (FMT) e a proteína tubulina do H. contortus usando o albendazol como fármaco de referência. O estudo de docking consensual utilizou os softwares Maestro 10.1, GOLD 5.3 e Autodock 4.2. Os resultados in sílico quando comparados aos resultados in vitro, demonstraram que o mecanismo de ação da hinoquinina, que se mostrou mais ativa, pode estar relacionado à inibição, tanto da β-tubul...

Piper cubeba is an Asian pepper that has a series of biological properties, including antiparasitic activity, and this activity is often attributed to cubebin, hinokinin and dihydrocubebin lignans, which are present in the plant in greater concentration. In vitro studies with the Piper cubeba extract and with the lignans cubebin, dihydrocubebina and hinokinin demonstrated that these compounds present important action against the several stages of the development of life of the Haemonchus contortus, being the hinokinin the most effective (EC50 = 68 μg / mL against eggs, EC50 <35 μg / mL against stage L1 and EC50 = 0.34 μg / mL against stage L3). Due to the relevance of these results, molecular docking studies were then carried out with these lignans in order to evaluate the action of these compounds with the phosphoethanolamine methyl transferase (FMT) proteins and the H. contortus tubulin protein using albendazole as a reference drug. The consensual docking study used the Maestro 10.1, GOLD 5.3 and Autodock 4.2 softwares. The in silico results when compared to the in vitro, demonstrated that the mechanism of action of hinokinin, which was more active, may be related to the inhibition of both β-tubulin and FMT-2. Although more research is needed, the results indicate tha... (Complete abstract click electronic access below) / Doutor

[pt] Na cultura ocidental moderna a monogamia é vista como a melhor, senão a única, forma de relacionamento amoroso. A monogamia refere-se à exclusividade emocional e sexual entre dois parceiros amorosos. Por outro lado, relacionamentos não-monogâmicos consensuais (RNMC) são aqueles em que há um acordo de não-exclusividade emocional e/ou sexual entre os envolvidos. Estudos mostram que algumas características individuais se relacionam com a escolha por relacionamentos monogâmicos ou RNMC, tais como níveis de apego, sociossexualidade e personalidade. RNMC fogem a cultura mononormativa e as pessoas que se envolvem nesse tipo de relacionamento são estigmatizadas. O objetivo da presente dissertação foi investigar o papel do tipo de relacionamento na relação entre a Exclusividade em Relacionamentos e o bem-estar subjetivo. Para isso foram desenvolvidos dois estudos. No primeiro, buscou-se construir uma escala para medir Exclusividade em Relacionamentos com itens contextualizados. A escala construída apresentou 11 itens, divididos em dois fatores (Monogamia e Fidelidade), bons indicadores de fidedignidade e evidências de validade satisfatórias. No segundo estudo, utilizou-se escala desenvolvida no estudo anterior para verificar o efeito da Exclusividade em Relacionamentos no bem-estar subjetivos de indivíduos em relacionamentos monogâmicos e RNMC. Os resultados indicaram que só há interação entre o fator monogamia da Exclusividade em Relacionamento com os afetos positivos e a satisfação de vida (fatores do bem-estar subjetivo) no grupo de pessoas em relacionamentos monogâmicos. A conclusão discute a relação entre a cultura mononormativa e a escolha por relacionamentos monogâmicos ou RNMC, assim como o impacto dessa escolha no bem-estar subjetivo. / [en] In modern Western culture monogamy is seen as the best, if not the only, form of loving relationship. Monogamy refers to emotional and sexual exclusivity between two loving partners. On the other hand, consensual non-monogamous relationships (CNMR) are those in which there is an emotional and/or sexual non-exclusivity agreement between those involved. Studies show that there are some individual characteristics that relate to choosing monogamous relationships or CNMR, such as attachment, sociosexuality and personality. CNMR escapes the mononormative culture and people who get involved in these types of relationships are stigmatized. The aim of this dissertation was to investigate the role of the type of relationship in the relationship between Relationship Exclusivity and subjective well-being. Two studies were developed. In the first, we sought to build a scale to measure Relationship Exclusivity with contextualized items. The constructed scale had 11 items, divided into two factors (Monogamy and Fidelity), good indicators of reliability and satisfactory evidences of validity. In the second study, the scale developed in the previous study was used to verify the effect of Relationship Exclusivity on the subjective well-being of individuals in monogamous relationships and CNMR. The results indicated that there is only interaction between the Monogamy factor of Exclusiveness in Relationship with positive affects and life satisfaction (factors of subjective well-being), in the group of people in monogamous relationships. The conclusion discusses the relationship between mononormative culture and the choice for monogamous relationships or CNMR, as well as the impact of this choice on subjective well-being.

Traditional psychotherapy with transgender clients has focused on helping gender dysphoric individuals assume an "opposite" gender role. However, recently, there have been calls for trans-positive therapy focusing on the exploration and affirmation of alternative gender identifications. The majority of the research on transgender identity has been conducted with male-to-female (MTF) identified, or transfeminine, individuals. Comparatively little attention has been given to the experience of female-to-male (FTM) identified, or transmasculine, individuals. The primary goal of this study was to explore constructs and identify underlying themes that transmasculine people use in constructing their gender identities in order to develop a structural model of transmasculine identity. Broadly speaking, results showed that transmasculine identity may be conceptualized on a continuum from an essentialist binary perspective to a constructivist non-binary perspective. This is reflected in the language the individual uses to self-identify - including identity labels, proper names and pronouns. Individuals define, experience, and embody transmasculine identities differently depending on a number of inter-related constructs including: (1) current stage of identity development and past transmasculine identity development events, (2) conceptions of masculinity and femininity, (3) context, and (4) sexuality. Further, if one of these constructs shifts it usually influences the others. Implications for theory, practice, and future research directions are discussed.

Discipline relationships are consensual adult relationships between submissive and dominant partners who employ authority and corporal punishment. This population uses social media to discuss the private nature of their ritualized fantasies, desires, and practices. Participants of these relationships resist a sadomasochistic label of BDSM or domestic abuse. I conducted in-depth interviews and narrative analysis of social media to explore experiences and identities of people in discipline relationships. The sample includes social media bloggers and past and present participants in discipline relationships. I compared explanations participants give for wanting and participating in discipline relationships. I combine identity theory, constructionism, post-structuralism, and critical feminism as an analytic frame to understand this practice sociologically. I found gender differences in the media format and communication style of participants, but the ritualized expressions for discipline relationships remain consistent regardless of gender. The social process of community identification for participants includes coming out, educating others and “inviting in.” The online community provides a forum for relationship negotiation techniques, and encouraging the embrace of non-normative sexual identity. Participants use social media to form a nascent social movement that resists normative views of sexuality and relationships in the dominant culture.

Based on her novel notions on the fundamental nature of creativity and the psychosocial need for an adequate assessment, Amabile (1983) proposes consensual assessment technique (CAT) to provide a "product-based" quantitative approach to evaluate creativity. The essence of CAT is that it delineates factors that influence and determine the "product" to be truly "creative", and emphasizes that a product or an observable reaction is the testimony of creativity. Amabile (1983) also implies creativity is not an individual phenomenon, but consists of three major components: task motivation, expertise and creativity skills. The purpose of this study is to examine the validity of Amabile's component model of creativity and to apply his model into the essay writings in primary school students, hence to test the attribution of CAT in providing a valid appraisal in creativity assessment. A "product-based" CAT was performed on 110 essays with 5 different topics written by 22 6th grade school students. A group of Chinese experts, made up of 3 children literature professors and 6 experienced primary school teachers, are in charge of evaluating all these essays. The evaluated results are used to determine if to determine if Amabile's model can be comparable to current psychosocial norms and if it can accurately delineates individual's creativity talent. According to our hypothetical working framework, the following results were expected; (1)motivation has a positive effect on creativity, (2)professional techniques have a positive effect on creativity (3)creative technique has a positive effect on creativity (4)the results of CAT showed a mutual consensus on defining creativity amongst the professional judges.

Adolescence is a time of experimentation and exploration. For many young people, a feature of this developmental period is the initiation of substance use. Whilst the majority of young people do not go on to develop substance use problems, any substance use has potential for danger. The current body of literature on the prevention of substance use problems suggests that in order to advance understanding, researchers must adopt a risk-focused approach. There is a wide range of indices that have been cited as risk factors for the development of substance use disorders. Chapter 2 explores some of the aetiological models and literature on risk factors with specific reference to psychological wellbeing, studies highlighting comorbid relationships between adolescent mental health and substance use problems, and the functional value of substances in relation to well-being. Although attention to psychological risk factors has received increased press in the literature, the number of controlled, longitudinal studies is relatively small. A review of recent studies (Chapter 3) indicates that the presence of anxiety, depression, low self-esteem or behavioural problems such as delinquency represent psychological risk factors for the development of later substance use problems, however findings are inconsistent and many studies do not examine differential predictive utility by substance or gender. Thus, Study 1 of this research aimed to add to this body of work by exploring the prediction of alcohol, cannabis and other illicit substance use at age fifteen from key indicators of psychological well-being taken at age thirteen. The data from a normative sample of high school students indicated subtle differences in trajectory for young males and females and effects specific to different drug categories. Delinquency emerged as the most consistent predictor in both males and females. Low self-esteem was also an important indicator for future female marijuana use and marijuana intoxication and both male and female other illicit substance use. The findings highlighted the need for a greater contextual understanding of the relationship between delinquency, self-esteem and substance use. The second study sought to provide a deeper understanding of these issues by examining the perceived functional value of substances in relation to psychological wellbeing, by means of a qualitative study of a group of young people who had experienced problems with their substance use. Chapter 4 explores the limited phenomenological research in this area, with a focus on studies which have used methods of measurement that highlight the perspective of young people. Using a Consensual Qualitative Research approach, Study 2 builds on the drug type and gender contrasts noted in Study 1, and explores the interface between substance use and psychological well-being in depth using a clinical population. A number of key functions are identified by young people, with evidence of both convergence and divergence across drug categories (alcohol, cannabis, other illicit substances). Interviewees reported six functions common to all substances; social connectedness, improve affect, positive self-transformation, better coping with problems, fun and laughter, and feeling intoxicated. Nine additional functions were identified in relation to cannabis and other illicit substances. Several gender differences were also noted, with males tending to report more positive reinforcement from alcohol and cannabis, and young females more frequently describing benefits related to use of other illicit substances. The concluding chapter (Chapter 5) reviews the main findings across both studies and their implications for theory, practice, and future research. Overall, the findings of the research provide support for both problem behaviour and adaptive models of adolescent substance use, and indicate that young people are capable of reflecting on their substance use experiences. Incorporating the wisdom of young people into risk frameworks may enhance prevention, education and intervention efforts.
