Esta pesquisa tem por finalidade analisar as construções sentenciais de tópico-comentário, de tópico marcado e de tópico não marcado, em produções textuais de estudantes do sexto ao nono anos do segundo segmento do ensino fundamental de escola pública localizada em comunidade da Zona Oeste do Rio de Janeiro, tendo sido analisadas 316 produções de um universo de 1040. O aporte teórico é o Funcionalismo, com ênfase na teoria dos três diferentes tipos de sujeito Sujeito Lógico, Sujeito Psicológico e Sujeito gramatical de Halliday (1994) e na teoria da Estrutura Informacional (Information Structure) de Lambrecht (1994). Partindo de análise quantitativa e qualitativa de corpus, investigou-se, de um lado, o percentual de aparecimento de construções de tópico marcado e não marcado e, de outro, os diferentes tipos de tópico não marcado e as motivações sintáticas e pragmático-discursivas de sua utilização. A análise foi feita em duas etapas. Primeiramente, para a identificação e a quantificação das construções sentenciais de tópico marcado, procedeu-se à investigação das seguintes variáveis: 1) tipo de tópico marcado mais recorrente, segundo categorização específica referente ao tópico e suas relações argumentais com o verbo 2) Posição mais frequente, considerando a estrutura textual e a ambiência sintática de favorecimento do uso do pronome correferente (presença/ausência de sintagma ou oração intercalada entre tópico sentencial e pronome correferente). A fim de investigar os contextos favorecedores de uso dos tópicos não marcados sujeito pronominal pleno de 3 pessoa e sujeito pronominal nulo de 3 pessoa, consideraram-se as seguintes variáveis: 1) tipo de oração e 2) conexão discursiva cf. Paredes Silva (2003). Os resultados obtidos permitem sistematizar as condições de uso das estruturas estudadas. Com relação às construções sentenciais de tópico marcado, verificou-se que se constitui em estratégia de ativar no discurso o elemento sobre o qual informações novas serão transmitidas, marcando-o como o tópico sentencial. Relativamente aos tópicos não marcados, as estratégias de uso estão relacionadas ao tipo de oração e ao grau de conexão discursiva da sentença. O uso do sujeito nulo está diretamente relacionado à conexão discursiva de grau 1, denominado ótimo. Uma breve análise de tais construções em autores consagrados da literatura brasileira e demais autores brasileiros contemporâneos permite afirmar que as construções de tópico, principalmente as que contêm tópico marcado, merecem uma atenção maior no ensino de Língua Portuguesa, uma vez que constituem uma estratégia pragmático-discursiva de uso corrente e de função relevante nos processos interacionais. O estudo das construções de tópico, portanto, merece uma atenção especial, uma vez que refletem a riqueza de nosso idioma, ao representar uma estratégia pragmático-discursiva que, se bem desenvolvida, constituir-se-á em uma ferramenta a mais para o usuário da língua no que concerne ao uso consciente e competente do idioma materno / The present study aims at analyzing sentence constructions of commentary topic, marked-topic and unmarked topic in textual productions of students attending the last four years of elementary education in a public school located in a poor community in the West zone of Rio de Janeiro. 316 out of 1040 productions have been analyzed. Functionalism has been used as the theoretical background with special emphasis on three different types of subject the Logical Subject, the Psychological Subject and the Grammatical Subject - Halliday (1994) and on Lambrechts information structure (1994). Based on the quantitative and qualitative analysis of the corpus, we have investigated, on the one hand, the percentage of marked and non-marked topic construction appearances and, on the other hand, the different types of non-marked topics and the syntactic and pragmatic discursive motivations of their usage. The analysis has been done in two stages. Firstly, for the identification and quantification of sentence constructions of marked topics, the investigation of the following variables has been made: 1st) most recurrent marked topic, according to specific categorization referring to the topic and its argumentative relationship with the verb, 2nd) most frequent position, taking into account the textual structure and the syntactic ambience of favoring the use of the coreferent pronoun (presence / absence of the syntagma or intercalated clause between sentence topic and coreferent pronoun). In order to investigate favoring contexts of the use of non-marked topics of 3rd person full pronominal subject and 3rd person null pronominal subject, the following variables have been considered: 1st) type of clause and 2nd) discursive connection, Paredes Silva (2003). The results obtained allow us to systematize the use conditions of the studied structures. When it comes to the sentence constructions of marked topic, we could perceive that it is a strategy of activating in the discourse the element about which the new information will be transmitted, marking it as the sentence topic. When it comes to non-marked topics, the strategies of use are related to the type of clause and to the degree of discursive connection of the sentence. The use of the null subject is directly related to the discursive connection degree 1, which is considered great. A brief analysis of such constructions in works of renowned authors in the field of Brazilian literature and other contemporary Brazilian authors allow us to say that topic constructions, especially the ones that contain marked topics, deserve greater attention in the education of Portuguese language, since they represent a pragmatic discursive strategy which is relevant and commonly used in interactional processes. Therefore, the study of topic construction deserves special attention since it reflects the richness of our language when it represents a pragmatic discursive strategy that, if well developed, can be one more tool for the language user when it comes to the conscientious and competent use of the mother tongue

This dissertation addresses three questions about administrative rulemaking: • Do comments submitted on proposed rules vary in identifiable ways? • Do these differences directly relate to the likelihood that recommendations will be associated with changes to regulations? • Can these characteristics be incorporated into a model that accurately predicts whether or not suggestions will coincide with changes to administrative rules? Using data collected from the Commonwealth of Virginia's Regulatory Town Hall, I analyze 2,534 comments that address 67 regulations proposed by state agencies during an 11-year period. I find that submissions do differ in meaningful ways. I also find statistically significant evidence that those differences are related to the probability that a requested change coincides with a subsequent modification to a rule. The principal result of this research is a model that predicts with a high degree of accuracy the outcome of participants' recommendations to alter proposed regulations. I also demonstrate the implications of these results and how failure to account for these differences undermines the legitimacy of conclusions that can be drawn from studies of notice-and-comment rulemaking. The primary contribution of this dissertation is methodological, but the empirical evidence presented here also raises questions about the value of citizen participation in notice-and-comment rulemaking in its current form. As a result, it challenges contentions that participation contributes to the democratic legitimacy of bureaucracy, serves as a safeguard against the influences of organized interests, or improves the substantive quality of administrative decisions. / Ph.

Selecting the correct methodology to better understand how consumers perceive food products is a challenging task for the food industry and sensory researchers alike. Free comment tasks (FC) utilize the advantages of open-ended questions to generate intuitive comments from untrained consumers to help identify and describe sensory attributes of products. However, FC data is typically analyzed using text analysis done by hand and is very cumbersome to organize and interpret. There is a growing need and interest to add to the library of data analysis tools used to understand FC data and consumer acceptance studies. Sentiment analysis is an opinion mining tool commonly used in marketing and computer science that extracts the emotional valence of the author from an unstructured text in the form of a sentiment score. A few studies in sensory evaluation use lexicon-based sentiment analysis which has many drawbacks: it is time-consuming, requires a large amount of data and dictionaries need to be tailored for food. We used a deep learning sentiment analysis approach to analyze and predict consumer sentiment/acceptance. The research objectives of this study are 1) to explore quicker and automated methods of sentiment analysis to better understand and predict consumer acceptance, and 2) to examine the advantages and disadvantages of sentiment analysis as a data analysis tool in sensory evaluation. We avoided the pitfalls of creating a sentiment lexicon by using online beer reviews to train a word embedding model where all of the relevant words in the review are converted into vectors. We used the distance and similarity (clustering) of the vectors to determine taste/flavor attributes that correspond to negative and positive sentiment. Next, to validate and test our model we gathered FC data in a consumer acceptance study. Panelists (N=68) were presented with six beers, one at a time and were instructed to taste and smell before leaving comments. We performed sentiment analysis on the FC data, and we compared our deep learning sentiment analysis model with three other pre-existing sentiment analysis models: SentimentR, VADER, and Liu and Hu opinion lexicon. Our deep learning sentiment analysis model had the highest accuracy (69%) and precision rate (73%). Overall, our findings provide an early look into the advantages and disadvantages of sentiment analysis applied to FC data in sensory evaluation. / Master of Science in Life Sciences / It can be a challenging task for the food industry and sensory researchers to select the correct methodology to better understand how consumers perceive food products. One method is Free comment tasks (FC) which use open-ended questions to generate comments from consumers. However, FC data is typically analyzed using text analysis done by hand and is very cumbersome to organize and interpret. This thesis is interested in investigating the application of data analysis methods from computer science on FC data. Sentiment analysis is an opinion mining tool commonly used in marketing and computer science that finds the emotional tone of the author from a text in the form of a sentiment score. First, we created a deep learning sentiment analysis model which uses algorithms to find useful patterns in the text that indicate positive and negative sentiment with minimal human intervention. We were interested if there were any advantages in creating a model so we compared our model to three widely used sentiment analysis models: VADER, Liu Hu and Sentiment R. Next, to test our sentiment analysis model and the three others we gathered FC data in a consumer acceptance study. Panelists (N=68) were presented with six beers, one at a time and were instructed to taste and smell before leaving comments. The research objectives of this study are 1) to explore quicker and automated data analysis methods to understand FC data, and 2) to examine the advantages and disadvantages of data analysis tools from computer science in sensory evaluation. Our deep learning sentiment analysis model had the highest accuracy (69%) and precision rate (73%). Overall, our findings provide an early look into the advantages and disadvantages of sentiment analysis applied to FC data in sensory evaluation.

This study uses the Securities and Exchange Commission's (SEC) comment letters to investigate the SEC's role as a monitor of financial reporting. I examine whether the SEC effectively comments on firms with poor disclosure quality. I utilize forward earnings response coefficients (FERC) as a measure of the market's perception of disclosure quality. I expect comment letter firms to have lower disclosure quality and thus lower FERCs. Secondly, within the firms selected for comment, I investigate whether the Division allocates a greater amount of resources towards firms with more severe disclosure deficiencies. Results indicate that comment letter recipients have significantly lower forward earnings response coefficients than non- recipients. Results also document that comment letter recipients have lower contemporaneous earnings response coefficients than non-recipients. These findings are consistent with the DCF being effective in selecting firms that are perceived by the market as having low disclosure and earnings quality. However, within comment letter firms, I am unable to provide any evidence that the DCF allocates more resources to firms with lower forward earnings response coefficients. / Ph. D.
