O presente estudo buscou avaliar o crescimento e o desenvolvimento de ratos tratados com dietas contendo a planta Pereskia aculeata, Miller e restrição de proteína. Foram utilizados 24 ratos machos, recém desmamados da linhagem Wistar. Os animais foram divididos em 4 grupos de dieta: padrão de caseína; restrição total de proteína; substituição de caseína por 40% de Pereskia aculeata e restrição de 40% de proteína. Avaliou-se o crescimento por meio da qualidade protéica com os testes de Coeficiente de Eficiência Protéica (PER), Razão Protéica Líquida (NPR) e Digestibilidade Verdadeira. Já para a análise do desenvolvimento foram realizados os testes de esquiva inibitória, reconhecimento de objetos, testes de reflexo e locomoção. Os resultados demonstram que o grupo que teve restrição de 40% de proteína apresentou valores maiores de Coeficiente de Eficiência Protéica e Razão Protéica Líquida quando comparados ao grupo padrão (p<0,01). Porém, quando analisado o ganho de peso, os animais com restrição protéica tiveram menor ganho ponderal que os do grupo padrão (p<0,01). Já o grupo que recebeu a Pereskia aculeata, Miller apresentou menor ingestão alimentar e maior excreção fecal quando comparado com o grupo padrão (p<0,05). Por isso, também revelou menores valores de Coeficiente de Eficiência Protéica e Razão Protéica Líquida (p<0,01). Além disso, a Digestibilidade Verdadeira também foi significativamente menor que o grupo padrão (p<0,01), fato provavelmente explicado devido ao alto teor de fibras da planta. Enquanto que os testes de desenvolvimento testes de reflexos. Por outro lado, não possui boa digestibilidade e não promove o crescimento adequado de ratos recém desmamados.

Lima.pdf: 3121777 bytes, checksum: 21ac03c60e84e3b7f26da586f703ed36 (MD5) Previous issue date: 2017-06-19 / The speech in defense of Sestius (oratio pro Sestio), delivered in 56 B. C., is one of the most fascinating pages written by Cicero, among his huge literary production, especially for the passion and vigor with which the speaker wields the words to defend his client and to express his impressions on the troubled political moment experienced by the Roman Republic in the end of the first half of the first century B. C.. The defense strategy established by that attorney in a cause that already seemed to be lost reveals to us a mature orator with long experience, forged in the long years of forensic practice. Concerning that specific point, the aim of this report is to study the rhetorical strategy, built by Cicero, in the oratio pro Sestio, to defend his client, from the primary use of a common topic (ός ός) to the three discursive genres of rhetoric, that is: the amplificatio (ὔς). The use of this argumentative resource allows to build a positive amplification, that occurs by increasing the figures of Sestius, of Cicero and of the optimates, along with a negative amplification, which happens through the decrease of the images of Clodius, Gabinius and Piso, contributing to the success of the speaker in winning the jury's adhesion to his thesis. And it is precisely for this reason that we consider, in this work, the amplificatio as an important key of interpretation of the argumentative strategy adopted in the judicial discourse analyzed here. We assume as theoretical framework the Aristotelian conceptions defined in his Rhetoric work, with the support of other works of classical rhetoric and new studies of rhetoric that corroborate the analysis of the text which is object of this research. With the aid of these analysis tools, the argumentative scheme of the oratio pro Sestio has been presented here starting from the átekhnai and éntekhnai proofs (non-technical or inartistics proofs and technical or artistic proofs), which were used by Cicero in the judicial discourse analyzed here, placing the amplification (amplificatio) in this Aristotelian division; we define the procedure of amplification according to the canons of classical rhetoric and the new studies of rhetoric; We identify in the text the techniques of amplification adopted by Cicero from the resources pointed out by Aristotle in Rhetoric; We identify in the style (elocutio), other linguistic resources that support amplification, such as the use of adjectives, nouns and verbs. Under a general perspective, this work reflects on the meanings of this argumentative resource in the work under study, seeking to know what justifies the adoption of this strategy and what are the subliminal messages of Cicero's arguments in promoting such amplifications. In the same way, this work also considers, in a transversal way, if this resource is related to a possible political project for the Republic. / O discurso em defesa de Séstio (oratio pro Sestio), pronunciado em 56 a. C., constitui uma das mais belas páginas escritas por Cícero em sua vasta produção literária, sobretudo pela paixão e pelo vigor com que o orador empunha as palavras para defender seu cliente e exprimir suas impressões sobre o conturbado momento político vivido pela República romana no final da primeira metade do século I a. C.. A estratégia de defesa estabelecida pelo advogado em uma causa que já parecia perdida revela-nos um orador maduro, detentor de larga experiência, forjada nos longos anos de prática forense. Observando particularmente esse ponto, a presente dissertação tem como objeto de estudo a estratégia retórica, construída por Cícero, na oratio pro Sestio, para defender seu cliente, a partir da utilização primordial de um tópico comum (òς ός) aos três gêneros discursivos da retórica: a amplificatio (ὔς). O emprego desse recurso argumentativo permite erigir uma amplificação positiva, que se dá por aumento das figuras de Séstio, de Cícero e dos optimates, ao lado de uma amplificação negativa, que se realiza pela diminuição das imagens de Clódio, Gabínio e Pisão, contribuindo para o êxito do orador na conquista da adesão do júri para sua tese de que Séstio merecia a absolvição. Daí, considerarmos, neste trabalho, a amplificatio como importante chave de interpretação da estratégia argumentativa adotada no discurso judicial em tela. Assumimos como arcabouço teórico as concepções aristotélicas definidas em sua obra Retórica, com o apoio de outras obras da retórica clássica e dos novos estudos de retórica que corroboram a análise do texto objeto desta pesquisa. Com o auxílio dessas ferramentas de análise, apresentamos o esquema argumentativo da oratio pro Sestio a partir das provas átekhnai (não técnicas ou inartísticas) e éntekhnai (técnicas ou artísticas), empregadas por Cícero no discurso judicial em tela, situando a amplificação (amplificatio) nessa divisão aristotélica; definimos o procedimento de amplificação segundo os cânones da retórica clássica e dos novos estudos de retórica; identificamos, no texto, as técnicas de amplificação adotadas por Cícero a partir dos recursos apontados por Aristóteles na Retórica; identificamos, na elocução (elocutio), outros recursos linguísticos que corroboram a amplificação, tais como o uso de adjetivos, substantivos e verbos. Numa perspectiva geral, este trabalho reflete sobre os sentidos desse recurso argumentativo na obra em apreço, perquirindo o que justifica a adoção dessa estratégia e quais as entrelinhas da argumentação de Cícero ao promover tais amplificações, bem como, pondera, de modo transversal, se tal recurso guarda relação com um possível projeto político para a República.

A socialização e a educação contribuem na formação dos indivíduos e favorecem o desenvolvimento do julgamento moral pró-social. Tal enunciado tem sido apresentado por estudos realizados com indivíduos de nível sócio-econômico médio em países desenvolvidos. O desenvolvimento do julgamento moral pró-social de indivíduosde nível sócio-econômico baixo e de países subdesenvolvidos ainda precisa ser investigada. Portanto, este estudo tem como objetivos: (a) investigar o julgamento moral pró-social de indivíduos que vivem nas ruas e não frequentam escolas comparando-os com indivíduos de nível sócio-econômico baixo, que frequentam escolas; (b) investigar os índices de ajuda diferencial dos indivíduos entre os potenciais receptores de ajuda. Quarenta meninos(as) de rua e 40 meninos(as) de escolas da Rede Municipal, de 9-12 e 13-16 anos de idade, metade de cada gênero, foram submetidos, individualmente, à Entrevista de Julgamento Moral Pró-social de Eisenberg. Algumas questões adicionais foram incluídas para avaliar os índices de ajuda diferencial entre os receptores de ajuda. Foram obtidos dados de identificação dos sujeitos por meio de uma Entrevista Inicial. Os dados coletados foram submetidos a análises quantitativas (frequências e ANOVAs). Os resultados revelaram que há diferença significativa no nível de julgamento moral pró-social de meninos(as) de rua e de escola (F[1,72] = 5.80; p< .05). Há, ainda, diferença significativa no índice de ajuda diferencial entre os receptores de ajuda (F[5,360]= 116.91; p<.OOI) e uma interação significativa de condição de vida e faixa etária (F[I,72]= 10.56; p<.Ol). Algumas análises extra-hipóteses foram realizadas, investigando a ocorrência e a clareza de expressão do julgamento moral pró-social. Os resultados são discutidos e comparados à literatura da área e a conclusão apresenta uma proposta para educação pró-social dos indivíduos aplicada à escola e às instituições de atendimento aos(às) meninos(as) de ruas.

Malgré leur utilité, les recherches en marketing social investissent encore peu le domaineenvironnemental (McKenzie-Mohr et al., 2011). Cette recherche s’intéresse à la persuasion des associations environnementales visant à favoriser l’adoption de comportements pro- environnementaux sur le littoral (CPL). Une étude qualitative menée auprès de 17 acteurs de la protection du littoral met en évidence que les différents éléments du marketing mix social sont déployés par ces acteurs avec une prédominance de la communication dans le cas des associations. La littérature mettant en avant une faible implication des individus envers l’environnement dans des contextes de loisirs et de tourisme, la deuxième étude s’intéresse plus spécifiquement aux heuristiques de communication. Ainsi, à travers une étude quantitative menée auprès de 1360 individus, nous analysons l’effet de deux heuristiques de communication : la marque associative comme source du message et les normes sociales au sein du message à travers une modélisation de leurs effets sur trois CPL (collecte de déchets, signature de pétition, don). Les résultats modélisent les antécédents de l’attachement à la marque associative et montrent un effet significatif positif de celle-ci sur l’adoption de CPL. Les normes sociales ne jouent quant à elles pas de rôle modérateur dans cette relation. Cette recherche contribue à la littérature sur le marketing social en montrant les effets de l’attachement à la marque associative sur l’adoption de comportements promus par une association. Elle contribue également à la littérature sur les comportements pro-environnementaux par l’étude de comportements dans un contexte peu étudié, le contexte récréatif. Sur le plan managérial, elle offre des pistes pour orienter les futures campagnes de communication des associations environnementales et les invite à travailler sur leurstratégie de marque pour accentuer les effets de ces campagnes. / Despite their usefulness, few researches in social marketing have been conducted in the environmentaldomain (McKenzie-Mohr et al., 2011). This research proposes to focus on the persuasion of environmental associations promoting the adoption of pro-environmental behaviors on the littoral. A qualitative study carried out among 17 actors in coastal protection shows that the different elements of the social marketing mix are deployed by these actors with a predominance of communication in the case of associations. As the literature highlights the low level of involvement in environmental issues in recreational and tourism contexts, the second study focuses on communication heuristics. Thus, through a quantitative study of 1360 individuals, we analyze the effect of two communication heuristics: the nonprofit brand as the source of the message and the social norms within the message through a modeling of their effects on three pro- environmental behaviors (Garbage collection, petition signing, donation). The results model the antecedents of attachment to the nonprofit brand and show its significant positive effect on the adoption of pro-environmental behaviors. However, social norms do not moderate this relationship. This research contributes to the literature on social marketing highlighting the effects of nonprofit brand attachment to the adoption of behavior promoted by the association. It also contributes to the literature on pro- environmental behavior by studying these behavior in a less studied context, the recreational context. From a managerial standpoint, it offers a way to guide future communication campaigns of environmental associations and invites them to work on their branding strategy to accentuate the effects of thesecampaigns.

Master of Arts / Department of Speech Communication, Theater, and Dance / Timothy R. Steffensmeier / This work explores the emergence and evolution of the rhetoric choice rhetoric as it pertains to contemporary American abortion politics. <Choice> is explored from an ideographic perspective, borrowing from the theoretical framework for ideographic rhetorical criticism established by Michael Calvin McGee. The analysis begins with a diachronic analysis of the emergence of the ideograph of <choice> within the law with an investigation of the written decisions in four Supreme Court cases central to the construction of the right to choose: Roe v. Wade (1973), Maher v. Roe (1977), Harris v. McRae (1980), and Webster v. Reproductive Health Services (1989). This investigation reveals a synchronic relationship between <choice> and another higher order ideograph, <liberty>. The criticism continues with an investigation of the usage of <choice> by pro-choice advocates in two documents published by NARAL Pro-Choice America, Choices: Women Speak About Abortion is a collection of women's narratives about their experiences obtaining an abortion, and Breaking Barriers, a guide for the development and implementation of proactive policy campaigns for pro-choice advocates. McGee's method is employed to investigate the ideographic usage of <choice> within these documents, revealing the ideographic abstraction that associates the alleged idea content of ideographs. This ideographic analysis reveals the inability of <choice> to live up to its alleged idea content as a result of the limitations inherent in the grounding of <choice> within the higher order ideograph of <liberty> and the impact of these limitations on particular populations, mainly indigent women in the United States.

Introduction: Haemophilia is an inherited bleeding disorder caused by a deficiency in one of the coagulation or blood clotting factors in the blood. When injured someone with haemophilia does not bleed more intensely than a person without haemophilia, but they tend to bleed for a much longer time. For people affected by severe haemophilia, the deficiency in coagulation factor can cause spontaneous internal bleeding in joints and muscles, as well as intracranial bleeding, and bleeding in soft tissues (e.g. nosebleeds or bleeding gums). The most common form is Haemophilia A which is caused by a deficiency in factor VIII. Haemophilia B is caused by a deficiency of factor IX and tends to be less severe than haemophilia A. Haemophilia is treated by replacing the deficient coagulation factor in the blood through intravenous injections of factor concentrate. Treatment can be on-demand, where medication is used to treat a bleeding episode; or preventative, where factor replacement treatment is used to increase the concentration of coagulation factor in the blood to prevent bleeding. Most young people with severe haemophilia in the UK follow a preventative treatment regimen (prophylactic treatment or prophylaxis). Patients with severe haemophilia A usually take 3 or 4 injections per week on alternate days, whereas patients with severe haemophilia B usually take 2 or 3 injections per week. There is good evidence that prophylaxis reduces bleeds and joint damage, whilst also improving quality of life. Therefore it is imperative for future health and functioning that young people with haemophilia (YPH) follow the prophylactic regimen they agreed with their haemophilia team. However, reported adherence levels among YPH vary widely (17 - 93%). Additionally, drivers of (non)adherence among YPH specifically have not been evidenced. Aims: The overall aim of the research described in this thesis was to gain a better understanding of the extent to which YPH adhere to their prophylactic treatment, and better understand what drives their (non-)adherence. The aims of the quantitative questionnaire study were to measure levels of adherence among YPH, and to assess whether psychosocial factors that have been shown to be associated with adherence among young people with other chronic illnesses, such as self-efficacy and social support, are also associated with adherence among YPH. Based on previous research on adherence and social cognitive models of illness, it was hypothesised that: - there would be differences between adolescents and young adults in relation to psychosocial correlates of adherence. - higher perceptions of pain and impact of pain would be associated with better adherence (De Moerloose, Urbancik, Van Den Berg, & Richards, 2008; Treil, Rice, & Leissinger, 2007). - higher perceptions of chronicity, consequences and treatment control would be predictive of higher adherence (Chilcot et al., 2010; Horne & Weinman, 2002). - greater perception of necessity of prophylaxis would be predictive of higher adherence whereas concerns about prophylaxis would not be predictive (de Thurah, Nørgaard, Harder, & Stengaard-Pedersen, 2010; Horne et al., 2013; Horne & Weinman, 1999; Llewellyn, Miners, Lee, Harrington, & Weinman, 2003; Wileman et al., 2014). - greater negative mood would be associated with lower adherence scores (Cox & Hunt, 2015; Helgeson, Siminerio, Escobar, & Becker, 2009; Snell, Fernandes, Bujoreanu, & Garcia, 2014). In addition, based on evidence that lower adherence results in worse disease outcomes (Berntorp, 2009; M. J. Manco-Johnson et al., 2007), it was anticipated that non-adherence to prophylaxis would be associated with higher numbers of bleeds and hospital visits. The aims of the qualitative interview studies with YPH, parents of YPH, and haemophilia healthcare professionals were to examine perceptions and experiences in relation to prophylaxis and how they make sense of these experiences. It was anticipated that this would provide evidence to gain a better understanding of the complexities surrounding prophylaxis and of the barriers and facilitators to adherence among YPH.

Using the action-based model of dissonance (Harmon-Jones, Amodio, & Harmon-Jones, 2009) and self-determination theory (Deci & Ryan, 2008) as theoretical frameworks, this thesis sought to explain the motivational processes underlying the environmental belief-action gap. The thesis examined why and how people resolve inconsistencies between their favourable attitudes toward environmental protection and their environmentally harmful behaviour. I hypothesized that accounting for individual differences in autonomous and controlled distal motives for effective and unconflicted action would clarify why attitude-behaviour inconsistencies are uncomfortable and explain how people compensate for them. I carried out 3 sets of studies to test the proposed hierarchical action-based model of inconsistency compensation in the environmental domain (HABICE). The objective of the first set of 3 studies was to test hypotheses about the role of individual differences in global and contextual motivation on dissonance arousal, in response to native attitude-behaviour inconsistencies encountered across and within important life domains. The second set of 3 studies tested hypotheses about the role of individual differences in contextual motivation toward the environment on the use and choice of strategies to compensate for a recent native inconsistency in the environmental domain. Finally, the goal of the final study was to test hypotheses about the moderating effect of social factors that direct attention to public (ego-invested) versus private (authentic) aspects of the self during the perception of inconsistencies on motivation and intentions to revise pro-global warming mitigation attitudes. The results of the 7 studies (total N = 2,209) supported the main predictions of the HABICE. The cumulative evidence supported the existence of two motivational orientations operating during inconsistency compensation processes. The autonomous motivational orientation, which embodies action tendencies to facilitate organismic integration via authentic regulation, motivated people to compensate for attitude-behaviour inconsistencies to restore the integrity of authentic self-structures. As a result, autonomous motivation toward the environment led people to reduce dissonance and to compensate for perceived inconsistencies by bringing their behaviour in line with self-relevant attitudes. The controlled motivational orientation, which embodies action tendencies to facilitate instrumental outcomes via contingent regulation, motivated people to compensate for attitude-behaviour inconsistencies to protect ego-invested self-structures by avoiding the aversive consequences of their counter-environmental actions. When inconsistencies aroused dissonance, controlled motivation predicted the use of overt behavioural strategies, for example enacting a compensatory pro-environmental action, to reduce dissonance. However, when inconsistencies did not arouse dissonance or there were barriers to behaviour change, controlled motivation predicted the use of cognitive strategies, for example revising or distorting pro-environmental attitudes, to minimize the inconsistency. Consequently, autonomous compensation processes predicted relatively infrequent attitude-behaviour inconsistencies in the environmental domain while controlled compensation processes predicted relatively frequent inconsistencies. The results imply that controlled motivation toward the environment may be driving the environmental belief-action gap, but that finding ways to promote autonomous motivation toward the environment in the general population has the potential to alleviate the gap.

Le tourisme est une industrie qui croît à une vitesse exponentielle. Elle est souvent mise de l’avant comme moyen d’amoindrir la pauvreté dans plusieurs régions du monde. Cependant, la littérature lui consacre beaucoup de critiques et de reproches. Ainsi, la mondialisation a favorisé la naissance d’un tout nouveau mouvement : le tourisme alternatif. C’est dans cette logique que la présente thèse s’attarde sur l’étude du tourisme alternatif dans la zone désertique algérienne, plus précisément à Timimoune. Ainsi, elle interroge les attitudes et perceptions des divers acteurs (touristes, agences touristiques, guides touristiques locaux et les populations locales) à considérer le tourisme alternatif comme levier à l’amélioration des conditions de vies des communautés locales en termes de santé, d’éducation et de création d’emploi.
