Pendant longtemps, le non-professionnel a été considéré comme un professionnel dont la situation de faiblesse était comparable à celle du consommateur et il était protégé comme tel. Or, le juge européen a défini le consommateur comme « visant exclusivement la personne physique ». Cela a conduit le juge français à nuancer sa position ; le non-professionnel est défini comme la personne morale n’exerçant pas d’activité professionnelle. De son côté, la notion de petit professionnel a été consacrée par les textes relatifs au droit de la consommation et au droit de la concurrence. Si ces contractants faibles sont protégés c’est avant tout parce qu’ils peuvent être marqués par une situation de faible économique, technique ou juridique. En tout état de cause la protection n’est accordée que par détermination de la loi et elle doit rester circonstanciée. Dans tous les cas, la protection de ces contractants est spécifiée par l’absence de standardisation car elle ne peut être calquée sur le modèle de protection du consommateur. Partant, la protection de ces contractants faibles est nécessaire contre les abus contractuels. Ainsi, le non-professionnel est essentiellement protégé contre les clauses abusives par l’appréciation du déséquilibre significatif dans les contrats de consommation. Alors que le petit professionnel est protégé par le contrôle du contenu du contrat et surtout contre toutes sortes d’abus dans les pratiques anticoncurrentielles. Aussi, les mécanismes de l’information prévus par le droit de la consommation, le Code civil ou ceux prévus au profit de l’acquéreur non-professionnel ou des non-avertis peuvent être étendus au profit du non-professionnel et du petit professionnel. / For a long time , the non-professional was considered as a professional whose weakness was comparable to that of the consumer and was protect as such. However, the European judge has defined the consumer as « exclusively targeting the natural person ». This led the french judge to qualify his position ; the non-professional is defined as the legal person not exercising a professional activity. For his part, the notion of small business has been enshrined in the text relating to consumer and competition low. If this weak contractors are protected it is primarily because they can be marked by a weak economic, technical or legal situation. In any case, protection is granted only by the determination of the law and must remain detailed. In all cases, the protection of this contractors is specified by the lack of standardization because it can not be modeled on the model of consumer protection. Therefore, the protection of these weak contractors is necessary against contractual abuses. Thus, the non-professional is essentially protected against unfair terms by appreciating the significant imbalance in consumer contracts. While the small business is protected by the control of the content of the contract and especially against all kinds of abuses in anti-competitive practices. Also, the information mechanisms provided by consumer law, the civil Code or those provided for the benefit of the non-professional purchaser or uninformed can be extended to the benefit of the non professional and the small business.

近年線上教學平台有著很大的發展，不管是國內的均一教學平台，或國外知名的可汗教育平台，都提供各種學科便利學生自主學習。而在高中化學計算的領域中，這些平台上均提供各種教學課程。美中不足的是在線上的練習系統中，往往題目數量少、題目變化少、無詳細解題步驟，這樣將不足以透過題目衡量一個學生在各個主題的學習上有無明顯的進步。 本論文的目的是改善上述問題。我們設計並實做一系統，只要使用者輸入簡單需求，即可自動產生高中化學問題以及伴隨詳細解答，可方便出題者快速產生各式不同主題的高中化學應用題目。我們的系統提供一個Web前端供使用者輸入所需要生成的題目之資訊。系統由此收齊相關參數之後，接著即可依據參數產生符合題目限制條件的化學問題生成模型。此問題模型為一hypergraph，節點代表已知或未知相關化學量，超連結(hyperedge)則代表數個化學量間的相依關係。有了此一以ASP(Answer Set Programming)表達的問題模型之後，系統即可利用ASP求解器(Solver)進行單一或多個題目生成，後續工作則是驗證每一生成題目之可行性並產生解題步驟，最後經由Django整合呈現於Web上。 / In recent years there has been great progress in the development of online learning. Well-known platforms such as international Khan Academic or local Junyi Academy in Taiwan provide courses in various subjects allowing interested students to study in a very convenient and autonomous way. As expected, courses on common subjects such as high school chemistry are offered with rich content by these platforms. However, there are shortcomings in these courses about the problems they provide for the students to practice or test. In addition to rich content, an ideal course should provide abundant problems of all possible topics, with each given detailed solution, so that students can evaluate their achievement of study by practicing or testing themselves with these problems. Unfortunately, no courses on these platforms meet the above requirements. The purpose of this thesis is to improve the above shortcoming by providing a system which can generate automatically word problems on various topics of high school chemistry, together with detailed accompanied solutions. Our system is a web-based application implemented using Django. It provides a front-end enabling the users to enter related information for the word problems they want the system to generate. According to the parameters collected from the front-end, our system will generate a corresponding chemical problem model. The model is a hypergraph with nodes representing known or unknown chemical quantities related to the problem and hyperedges representing relations or dependencies among these quantities. After the model is generated as a logic program of ASP(Answer-set Programming), the system will use an ASP solver to generate one or more candidate problems. Subsequent works are then used to verify the feasibility of each problem and produce a solution for the feasible one. Finally the generated problems as well as solutions are wrapped in the server side and then sent to and presented friendly in the client's browser.

Explorando a dimensão estético-simbólica, o estudo indaga sobre a influência da estética dos produtos do mobiliário-popular nas interpretações e associações semânticas e simbólicas dos usuários, objetivando investigar como ocorre a interação e a relação afetiva. Para isso, foi feita análise do público consumidor, considerando o seu perfil, analisando a mudança de hábitos e de consumo que se deu através do aumento significativo da renda e do acesso à informação nos últimos anos, levantando a hipótese de que os usuários e consumidores do mobiliário popular estão mais criteriosos quanto à avaliação do design desses produtos e das relações posteriores que eles desenvolvem com os mesmos. O método estudado abrangeu entrevistas e observações, e utilizou modelo da Interação Significante para classificar e caracterizar as respostas dos usuários nas dimensões prática e emocional. Os resultados do estudo levaram a conclusão de que as pessoas estão insatisfeitas com os produtos do mobiliário popular e, mesmo quando elegem produtos como seus preferidos, para a maior parte dos entrevistados, existe algum tipo de reclamação ou mudança que gostariam de realizar e, na maioria das vezes, essa alteração ou insatisfação está relacionada ao design do produto. / This research shows the user-product emotional relationship, having as object of study products that are part of the popular furniture, following the principle that the affective relationships that people develop with the products interfere not only in the purchase decision, but also in the feeling well-being and attachment to artifacts. Exploring the aesthetic-symbolic dimension, the study inquires about the influence of the aesthetics of popular furniture products on the semantic and symbolic interpretations and associations of users, aiming to investigate how the interaction and the affective relationship occur. In order to do this, the consumer public was analyzed taking into account their profile, analyzing the change in habits and consumption that occurred through a significant increase in income and access to information in recent years, raising the hypothesis that users and consumers of the popular furniture are more judicious as the evaluation of the design of these products and of the later relations that they develop with them. The method studied included interviews, observations, and used the model of Significant Interaction to classify and characterize the users' responses in the practical and emotional dimensions. The results of the study led to the conclusion that people are dissatisfied with popular furniture products and even when they choose products as their preferred, most respondents find that there is some kind of complaint or change they would like to make and most times this change or dissatisfaction is related to the product design.

The dissertation deals with the experimental research that examines the effectiveness of the ESP e-learning course of Business English in comparison with the method of face-to-face instruction. The literature review has revealed the absence of scientific research in the field of our investigation. It has justified why our proposed research study should be conducted and led us to the rationale for our research. The main objective of this dissertation was to find out whether the e-learning method was as effective as the face-to-face instruction, i.e., whether there were no statistically significant differences between the results of the students who completed the e-learning course (experimental group) and those who completed the face-to-face course (control group). Simultaneously, we examined whether there were any statistically significant differences in the results of the students at the beginning of the course and at the end of the course within individual groups, i.e., whether the students improved their skills and vocabulary. The supplementary objective was to find out the students' opinions on the effectiveness of e- learning depending on the frequencies of their responses and on their qualitative signs. The practical outcome is the ESP e-learning course for the subject of Business English in...

Text in Afrikaans / Vrouemisdaad is 'n komplekse sosiale verskynsel. 'n Aspek van vrouemisdaad wat in die onderhawige proef skrif ondersoek word, is om aan die hand van bestaande teoriee te probeer verklaar waarom vroue soveel minder misdaad as mans pleeg. Ten einde antwoorde op die vraag te vind, is 'n kwantitatiewe ondersoek na die gemeenskap se houding rakende die vrouemisdadiger en 'n kwalitatiewe ontleding van die beskikbare literatuur gedoen. 'n Intensiewe verkennende studie van die beskikbare literatuur het getoon dat die gemeenskap, navorsers en akademici bepaalde persepsies huldig oor die vrouemisdadiger wat nie altyd met die werklike beeld strook nie. Alhoewel die getalle van vrouemisdadigers deur die jare toegeneem het, het die tipe misdade wat vroue pleeg weinig verander en die omvang van vrouemisdaad proporsioneel tot die bevolking dieselfde gebly. Geen enkele teorie of benadering op sigself bied 'n algemene verklaring vir die verskynsel van vrouemisdaad nie; dit kan hoogstens as gedeeltelike verklaring dien. 'n Algemene verklaringsmodel vir vrouemisdaad is egter opgestel wat terselfdertyd as samevatting van die geselekteerde teoriee dien. Met behulp van die argivale metode is 'n profiel van die gekommitteerde vrouemisdadiger saamgestel om 'n basiese kennissisteem van die vrouemisdadiger daar te stel. Statisties beduidende verbande is gevind tussen die karakteristieke van die blanke gekommitteerde vrouemisdadiger se huwelikstaat, aantal kinders en bedrog. Die kwantitatiewe ondersoek bestaan uit die ontleding van 516 respondente se persepsies oor die vrouemisdadiger. Uit die resultate van verskeie statistiese tegnieke blyk dit dat die ondersoekgroep, wat blanke respondente van vier voorstede uit struktuurstreekplansel 22 van Pretoria verteenwoordig, bepaalde persepsies en opvattings aangaande die vrouemisdadiger het. Die persepsiemeting het aan die lig gebring dat daar verskille in persepsies bestaan oor die vrouemisdadiger en vrouemisdaad in die blanke gemeenskap bestaan. Hierdie persepsies stem nie ooreen met die beeld wat blyk uit die onderhawige navorsing nie. Statisties beduidende verskille in persepsies tussen manlike en vroulike respondente van die ondersoekgroep is ook gevind. Daar bestaan verder statisties beduidende verskille tussen respondente van verskillende voorstede, onderwyspeile, taalgroepe, en ouderdomsgroepe. / It can be said that female crime is a complex phenomenon. An aspect of female crime that is investigated in this thesis is to explain, with reference to existing theories, why women commit fewer crimes than men. In an attempt to answer this question, a quantitative investigation regarding the attitude of society towards the female criminal as well as a qualitative study of the available literature, was conducted. An intensive exploratory study on female crime indicated that and academics have a certain of the available the community, perception of literature researchers the female criminal which does not always correspond with the facts. Although the number of female criminals has increased through the years the extent of female crime, proportionally to the population size, has remained constant, and the type of crime committed by women has remained relatively unchanged. It seems clear that no single theory or approach can explain female crime, it can at best give a partial explanation. An integrated explanation model for female crime has been compiled which simultaneously serves as a summary of selected theories. By means of the archival research method a profile of the female prisoner was compiled, to be used as a basis for the researcher's scientific knowledge of this phenomenon. Statistically significant relations were found to exist between the characteristics of the white female prisoner's marital status, number of children and fraud. The quantitative investigation consisted of an analysis of the responses of 516 respondents on an attitude scale. The results of various statistical techniques show that the research group, which represents respondents fr6m four suburbs from structure plan cell 22 of Pretoria, reveals certain attitudes and beliefs about the female criminal. This attitude measurement indicated that differences in perceptions regarding the female in the white community do criminal and female exist. Furthermore crime these perceptions do not correlate on the female criminal in with the information gathered this research. Statistically significant differences in attitude were found between male and female respondents, respondents from the different suburbs, with different qualifications, of different language groups, and of different age groups. / Sociology / D.

For centuries humans and animals have shared their lives. However, it is only in recent decades that the phenomenon of the human-animal bond and the possible therapeutic implications thereof has begun to be explored. Due to this exploration, many research programmes have sprung up around the world, investigating the implementation of animals as an intervention in various institutions. These programmes have produced overwhelmingly positive and encouraging results. However, the research remains sparse where the significance of a naturally occurring human-animal bond is concerned. From within an ecosystemic worldview, the relationship between humans and animals in the wider family system has not been extensively investigated. This dissertation explores such a relationship, investigating the meanings and experiences within the relationship, and how this relationship and significant systems around it impact one another. The implications and possible therapeutic nature of this type of relationship will be considered. / Psychology / M.A. (Clinical Psychology)

This thesis is focused on role of the external auditor and risks and ethical behavior during his working. During individual phases of audit auditor must pay attention to many parts to determine no misrepresentation information in financial statements. Too he checks up into questions of ethical behavioral, for example by the evaluation of contract´s risk.

We are living in an era in which the school is not the main place where learning happens, and the knowledge is acquired through the interaction in the networks and communities of practice (FAIRCLOUGH, 2001) what makes us think about new ways of teaching and learning. It is necessary that the atmosphere of the classroom translates the transformations of the society, so that it can be considered as a community of practice, place where the knowledge is built. The role that the school should assume, together with the teacher, is to promote opportunities for the construction of new knowledge and for the approach of new cultures. Concerning teaching and learning of foreign language, the proximity among cultures is still more relevant. In new times the progress of the technology has been propitiating a narrowing in the contact among the people, and it is necessary to know not only the language, but also the culture of the other. Learning a foreign language means to familiarize with other manners of acting, thinking and communicating. We understand this practice can be favored by a communicative approach of teaching, whose focus is the united construction of the knowledge through the interaction and negotiation of meaning, so that the learning is relevant to the learner. When we think about procedures that make possible the implementation of a communicative teaching in agreement with the new demands of the modern society, so that it promotes opportunities for the construction of the knowledge through the interaction and negotiation meaning, and, at the same time, it can contemplate the approach of multiple linguistic and cultural varieties of the Spanish language, it seems opportune the use of the movie as a didactic resource. Although the films can be considered as an efficient didactic resource for the implementation of the communicative teaching of languages, for its entertainment nature and for its capacity of promoting the students' larger involvement in the accomplishment of significant activities, we noticed that its use is still quite limited in the teaching process. Considering that gap, the objective of this qualitative research of ethnographic base is investigate the use of the film The Motorcycle Diaries as didactic content in the context of Spanish teaching as foreign language, according to the theory of the significant learning (GEE, 2004; RICHARDS, 2005; SAVIGNON, 2001). The data were obtained by questionnaires, focal group and teacher notes, and they show that the film represents an effective way to present the linguistic input in a contextualized way, besides involving the students in interaction activities and negotiation of meaning, stimulating the critical thought and the world knowledge, and contributing significantly for the development of the student's autonomy as a language learner. / A nova configuração da sociedade pós-moderna tem exigido mudanças no âmbito de ensino. Vivemos em uma era em que a escola já não é considerada o principal local onde ocorre a aprendizagem, e o conhecimento é adquirido por meio da interação e do pertencimento às diversas redes sociais (FAIRCLOUGH, 2001) fato que nos leva a refletir sobre novas maneiras de construir e lidar com o conhecimento. É preciso que o ambiente da sala de aula traduza as transformações da sociedade, de forma que possa configurar-se, efetivamente, como comunidade de prática, lugar de construção do saber. O papel que a escola deve assumir, juntamente com o professor, é o de promover oportunidades para a construção de novos saberes e para o conhecimento e aproximação de outras culturas. Em se tratando de ensino e aprendizagem de língua estrangeira (LE) a proximidade entre culturas torna-se ainda mais relevante. Nos novos tempos o avanço da tecnologia tem propiciado um estreitamento cada vez maior do contato entre os povos, e é preciso conhecer não somente a língua, mas também a cultura do outro. Aprender uma língua-alvo significa familiarizar-se com outros modos de agir, pensar e comunicar-se. Entendemos que essa prática pode ser favorecida por uma abordagem comunicativa de ensino, cujo foco é a busca pela construção conjunta do conhecimento por meio da interação e da negociação de sentidos, de forma que a aprendizagem seja significativa ao aprendente. Ao refletirmos sobre procedimentos que viabilizem a implementação de um ensino comunicativo de acordo com as novas exigências da sociedade moderna, de forma que promova oportunidades para a construção do conhecimento por meio da interação e da negociação de sentidos, e que, ao mesmo tempo, possa contemplar a abordagem de múltiplas variedades linguísticas e culturais do idioma espanhol, parece-nos oportuna a inserção do cinema como recurso didático para esse fim. Embora o cinema possa configurar-se como um recurso didático eficiente para a implementação do ensino comunicativo de línguas, por seu caráter lúdico e por sua capacidade de promover maior envolvimento dos alunos na realização de atividades significativas, percebemos que seu uso ainda é bastante limitado no âmbito de ensino de língua estrangeira. Considerando essa lacuna, o objetivo desta pesquisa qualitativa, de base etnográfica, foi investigar o uso do filme Diários de Motocicleta como conteúdo didático no contexto de ensino de espanhol como língua estrangeira, tomando por base os pressupostos teóricos da aprendizagem significativa (GEE, 2004; RICHARDS, 2005; SAVIGNON, 2001). A análise dos dados, obtidos por meio de questionários, grupo focal e notas de campo, revela que o filme representa uma maneira eficaz de apresentar o insumo linguístico contextualizado, de envolver os alunos em atividades de interação e negociação de sentidos, de estimular o pensamento crítico e o conhecimento de mundo, além de contribuir significativamente para o desenvolvimento da autonomia do aluno como aprendente de línguas.

Ao longo do tempo e da história, o homem vive os seus dilema e conflitos. A condição humana não tem cura. A apartação entre sujeito e objeto, entre o ser e a natureza, estabeleceu para a espécie humana modos muito singulares de sobrevivência, distinto dos demais seres, os seres da natureza. O que este projeto intenta é ressaltar alguns aspectos do conflito em que se engendra esse ser da linguagem, as tensões frente ao outro, os ideais que concorrem para uma de nossas práticas mais apaixonante: a política. Aqui a política tem as medidas simbólicas e imaginárias, é mais uma invenção que toma forma a partir do vazio do real, como a peça do oleiro, e se lança nas mais variadas captações dos ideais, esses que de um modo e de outro, dão versos às ideologias, chamem-nas de metáforas, metonímias, argumentos, retóricas etc.; a política é fundamentalmente uma prática do verbum. E em sendo verbal, a política está inscrita e escrita nos discursos, nos sintomas e na história. Ei-la num trinômio que é um autêntico nó borromeu, que de certo modo foi o meu esforço ao lançar-me na aventura que no plano diverso dos discursos e da topologia: história e a-história, a saber, num deslizamento a dizer de uma abordagem do real, a qual, intento algo da ordem de uma transição subjetiva. Para tal, este projeto discorre em três partes: as narrativas históricas, digo: os significantes da história; as articulações discursivas e os sintomas sociais. Aqui o sintoma tem a função de fornecer conteúdos para a história, a partir das injunções discursivas tal a elaboração de Lacan. A metodologia que sigo se assenta numa proposição teórica que aborde os objetos reais em sua imisção, e repetição, nos objetos da história, pretendendo, quiçá, uma composição narrativa que serpenteie o real, como numa poética, que enuncie um molejo, um requebro das palavras em função que dizer o real é fazê-lo não pela busca de sentido, mas pela errância que concerne essa gramática, errância que é a da subjetividade a partir do inconsciente, e que é do fato de que os objetos nesse enredo não são os da realidade, são os da quebra de sentido, a saber, são os das inserções do significante e são também os assintóticos, os intangíveis, quer seja, os que denotam o impossível, via a que nos aponta a psicanálise. Que aponta para uma dimensão do mal-estar na cultura e na civilização, digo: a civilização como mal-estar, a que se recobre, portanto, não apenas a sintaxe, mas a semântica do sintoma, isso que faz discurso e que é da lógica da diferença, no que articula o laço social, problematizado aqui na querelas ideológicas de nosso tempo e nas promessas de gozo seja na economia psíquica seja na economia política-social / Humankind faces its dilemmas and conflictis over the years and history. The human being condition does not seem to have any cure. Since the self and object, as well as the being and the nature tore apart, the human being established many particular ways of survival, differently from the rest of the natural beings. This paper comes to highlight some aspects of conflicts which embody this being in language; all tensions face to others, all ideals that contribute to one of the most passionate human practices: politics. Herein, politics undesrtands the symbolic and imaginary measurement, that is one more invention which takes a format from an emptiness of real, such as the piece of the potter, and goes through a variety of acquirements of the ideal, the same ideal that, sooner or later, creates ideologies, once called from metaphors or metonymies up to reasoning, and rhetorical arguments. The politics is a pratice of verbum, effectively. Upon being verbal, politics is both subscribed and underlined onto the discourse, onto the symptoms, and onto history. This paper comes to understand language as a trinonym part from the discourse itself, and apart from topology: history and a-history coming to meaning an approach of real within a subjective transition. In order to mention the project, this paper intends to separate the rationale into three parts: the historical narratives, in others words, the historical significants; the discoursive constellations; and the social symptoms. It is also to mention that the symptom has its function as a vehicle of historical contents; starting from the discoursive injunctions, according to Lacans theoretical resources. The methodology used in this paper concerns to a rationale that considers the real object and its immiscion, its repetition over historical objects. This paper also intends to compose a narrative that embodies the reality, just like the Poetic does. It also comes to highlight the meaning of words and their disorder int the utterance, coming to understand that real is not what it means, but what it does not mean through errors by the sense of grammar correctness. Such errors come from both subjectiveness and inconscienceness; from the fact that the object does not have its origin in reality, but from its non-meaningful significant, as well as the assintotics, e.g., the ones that denote the impossible, by the understanding of psychoanalysis. All those aspects above mentioned come to show the dimension of indisposition in culture and civilization, in other words, the civilization in indisposition that disguises, not only the syntax, but the semantics of the symptom which comes the discourse true, and therefore, it promises a well-fare for both psycho economy and political-social economy

No. of bitstreams: 1 ManassesPN_DISSERT.pdf: 2146671 bytes, checksum: a562634d1e686680a598403ed93762dd (MD5) Previous issue date: 2010-05-17 / Two-level factorial designs are widely used in industrial experimentation. However, many factors in such a design require a large number of runs to perform the experiment, and too many replications of the treatments may not be feasible, considering limitations of resources and of time, making it expensive. In these cases, unreplicated designs are used. But, with only one replicate, there is no internal estimate of experimental error to make judgments about the significance of the observed efects. One of the possible solutions for this problem is to use normal plots or half-normal plots of the efects. Many experimenters use the normal plot, while others prefer the half-normal plot and, often, for both cases, without justification. The controversy about the use of these two graphical techniques motivates this work, once there is no register of formal procedure or statistical test that indicates \which one is best". The choice between the two plots seems to be a subjective issue. The central objective of this master's thesis is, then, to perform an experimental comparative study of the normal plot and half-normal plot in the context of the analysis of the 2k unreplicated factorial experiments. This study involves the construction of simulated scenarios, in which the graphics performance to detect significant efects and to identify outliers is evaluated in order to verify the following questions: Can be a plot better than other? In which situations? What kind of information does a plot increase to the analysis of the experiment that might complement those provided by the other plot? What are the restrictions on the use of graphics? Herewith, this work intends to confront these two techniques; to examine them simultaneously in order to identify similarities, diferences or relationships that contribute to the construction of a theoretical reference to justify or to aid in the experimenter's decision about which of the two graphical techniques to use and the reason for this use. The simulation results show that the half-normal plot is better to assist in the judgement of the efects, while the normal plot is recommended to detect outliers in the data / Os experimentos fatoriais 2k s?o muito utilizados na experimenta??o industrial. Contudo, quanto maior o n?mero de fatores considerados maior ser? a quantidade de provas necess?rias para a execu??o de um experimento, e realizar replica??es dos tratamentos pode ser invi?vel, considerando as limita??es de recursos e de tempo, tornando tal experimento dispendioso. Nestes casos, s~ao utilizados os fatoriais 2k n?o replicados. Mas, sem replica??oo, n?o ? poss?vel obter uma estimativa direta da variabilidade do erro experimental para se avaliar a signific^ancia dos efeitos. Uma das poss?veis solu??es para este problema ? utilizar os gr?fificos normal ou semi-normal dos efeitos. Muitos pesquisadores usam o gr?fifico normal, ao passo que outros preferem o semi-normal e, em muitas vezes, para ambos os casos, sem alguma justificativa. A controv?rsia sobre o uso destas duas t?cnicas gr?ficas ? o que motiva a realiza??o do presente trabalho, uma vez que n?o h? registro de procedimento formal ou teste estat?stico que indique \qual delas ? melhor". A escolha entre os dois gr?fificos parece ser uma quest~ao subjetiva. O objetivo central desta disserta??o ?, ent?o, realizar um estudo comparativo experimental dos gr?fificos normal e semi-normal no contexto da an?lise dos experimentos fatoriais 2k n?o replicados. Tal estudo consiste na constru??o de cen?rios simulados, nos quais o desempenho dos gr?fificos em detectar os efeitos significativos e identificar valores discrepantes ? avaliado com o intuito de verificar as seguintes quest?es: Um gr?fifico pode ser melhor que o outro? Em que situa??es? Que informa??es um gr?fifico acrescenta ? an?lise do experimento que possam complementar aquelas fornecidas pelo outro gr?fifico? Quais as restri??es no uso de cada gr?fifico? Com isso, prop?e-se confrontar estas duas t?cnicas; examin?-las simultaneamente a fim de conhecer semelhan?as, diferen?as ou rela??es que possam contribuir para a constru??o de um referencial te?rico que sirva como um subs?dio para justificar ou auxiliar na decis~ao do pesquisador sobre qual das duas t?cnicas gr?fificas utilizar e o porqu^e deste uso. Os resultados das simula??es mostram que o gr?fifico semi-normal ? melhor para auxiliar no julgamento dos efeitos, ao passo que o gr?fifico normal ? recomendado para detectar a presen?a de valores discrepantes nos dados
