A ideia de um protestantismo rural é caracterizada pela relação dos crentes com o lúdico e a familiaridade com o sagrado. Este tipo protestante tupiniquim, genuinamente brasileiro, se desenvolveu em locais de pouca ou nenhuma resistência por parte do catolicismo, religião hegemônica no contexto brasileiro, fator que possibilitou arranjos e rearranjos que o diferenciam do protestantismo dito oficial. Esta pesquisa procura, pois, identificar algumas características deste protestantismo rural, principalmente sua interação com as culturas populares tradicionais no contexto fundante da Igreja Presbiteriana de Cabeceira Grande-MG. Através da metodologia de pesquisa em história oral e micro-história, o foco do estudo será aproximado à vida de duas importantes figuras que se destacaram neste contexto: o lavrador Manoel Moises e a parteira Mãe Bela. Manoel Moises, pioneiro protestante, chega à região em 1947, trazendo a sua mudança em um carro de bois. A origem da Igreja Presbiteriana em Cabeceira Grande deve-se às atividades deste pregador leigo e autônomo. Posteriormente, a comunidade já formada recebe a visita de pastores vinculados às Agências Missionárias estrangeiras atuantes na região. Assim como Manoel Moises é referência constante nas memórias locais, Mãe Bela, uma das primeiras convertidas ao protestantismo naquele lugar, é também lembrada por sua atuação como parteira e pelos seus conhecimentos da medicina tradicional, articulados com o imaginário religioso local. Mãe Bela também foi a doadora do terreno em que foi construído o templo da Igreja Presbiteriana, inaugurado em 1970.

In recent years, much interest has focused on the beneficial effects of administering potentially harmful therapeutic agents in drug carriers so as to reduce their toxic side effects. Rheumatoid arthritis is a chronic systemic disease with progressive destruction of the Joints and long term patient disability, Corticosteroids have been shown to retard the progression of Joint destruction but are limited in their use due to adverse side effects,This project, following the line of investigation started by other workers, was designed to study the use of microspheres to deliver corticosteroids to inflamed tissues by both the oral and intravenous routes. Hydrocortisone (HC)-loaded albumin microspheres were prepared by three different methods, by direct incorporation of HC within the particles, by indirect incorporation of HC by the enzymatic conversion of hydrocortisone-21-phosphate (H-21-P) to HC within the particles, and by the adsorption of HC onto the surface. HC was also loaded with PLA microspheres. The level of corticosteriod loading and in vitro release from microspheres was determined by HPLC analysis. A reversed-phase, ion-pairing HPLC method was developed to simultaneously measure both HC and H-21-P. The highest level of corticosteroid loading was achieved using the incorporation of H-21-P with enzymatic conversion to HC method. However, HPLC analysis showed only 5% of the incorporated steroid was HC. In vitro release rates of steroid from albumin microspheres showed >95% of incorporated steroid was released within 2 hours of dissolution. Increasing the protein:steroid ratio, and the temperature and duration of microsphere stabilization, had little effect on prolonging drug release. In vivo studies, using the carrageenan-induced rat hind-paw model of inflammation, indicated steroid-incorporated microspheres administered both orally and intraperitoneally were not therapeutically advantageous when compared to equivalent free steroid doses. The ability of orally and intravenously dosed [125I]~albumin microspheres (2.67 μm mean diameter) to accumulate in acutely and chronically inflamed tissues was investigated, The subcutaneous air-pouch was the model of inflammation used, with carrageenan as the inflammatory stimulus. Acute and chronic inflammation was shown to be consistently formed  in pouch tissues in terms of cell infiltration and fluid exudate formation in the pouch cavity. Albumin microspheres were shown to accumulate in the inflamed tissues and pouch fluids after both oral and intravenous administration. Preliminary, confirmatory studies using latex microspheres and quantitation by GPC analysis, also indicated microsphere accumulation in both acutely and chronically inflamed air-pouch tissues. tntl lUr"'poucbtis,sues; The results indicate the uptake and transfer of microspheres across the gastrointestinal tract into the circulation and their migration through disrupted endothelium and basement membranes at the inflamed sites. , .

In recent years, much interest has focused on the significance of inducing not only systemic immunity but also good local immunity at susceptible mucosal surfaces. A new field of mucosal immunity has been established as information accumulates on gut-associated lymphoid tissue, bronchus-associated lymphoid tissue and nasal-associated lymphoid tissue (GALT, BALT and NALT, respectively) and on their role in both local and systemic immune responses. This project, following the line of investigation started by other workers, was designed to study the use of microspheres to deliver antigens by the mucosal routes (oral and nasal). Antigen-containing microspheres were prepared with PLA and PLGA, by either entrapment within the particles or adsorption onto the surface. The model protein antigens used in this work were mainly tetanus toxoid (TT), bovine serum albumin (BSA) and γ-globulins.In vitro investigations included the study of physicochemical properties of the particulate carriers as well as the assessment of stability of the antigen molecules throughout the formulation procedures. Good loading efficiencies were obtained with both formulation techniques, which did not affect the immunogenicity of the antigens studied. The influence of the surfactant employed on the microspheres' surface properties was demonstrated as well as its implications on the adsorption of proteins. Preparations containing protein adsorbed were shown to be slightly more hydrophobic than empty PLA microspheres, which can enhance the uptake of particles by the antigen presenting cells that prefer to associate with hydrophobic surfaces. Systemic and mucosal immune responses induced upon nasal, oral and intramuscular administration have been assessed and, when appropriate, compared with the most widely used vaccine adjuvant, aluminium hydroxide. The results indicate that association of TT with PLA microspheres through microencapsulation or adsorption procedures led to an enhancement of specific mucosal IgA and IgG and systemic IgG responses to the mucosal delivered antigens. Particularly, nasal administration of TT produced significantly higher serum levels of specific IgG in test animals, as compared to control groups, suggesting that this is a potential route for vaccination. This implies the uptake and transfer of particles through the nasal mucosa, which was further demonstrated by the presence in the blood stream of latex particles as early as 10 min after nasal administration.

Following Andersen's (1986, 1991) study of untutored anglophone learners of Spanish, aspectual features have been at the centre of hypotheses on the development of past verbal morphology in language acquisition. The Primacy of Aspect Hypothesis claims that the association of any verb category (Aktionsart) with any aspect (perfective or imperfective) constitutes the endpoint of acquisition. However, its predictions rely on the observation of a limited number of untutored learners at the early stages of their acquisition, and have yet to be confirmed in other settings. The aim of the present thesis is to evaluate the explanatory power of the PAH in respect of the acquisition of French past tenses, an aspect of the language which constitutes a serious stumbling block for foreign learners, even those at the highest levels of proficiency (Coppieters 1987). The present research applies the PAH to the production of 61 anglophone 'advanced learners' (as defined in Bartning 1997) in a tutored environment. In so doing, it tests concurrent explanations, including the influence of the input, the influence of chunking, and the hypothesis of cyclic development. Finally, it discusses the cotextual and contextual factors that still provoke what Anderson (1991) terms "non-native glitches" at the final stage, as predicted by the PAH. The first part of the thesis provides the theoretical background to the corpus analysis. It opens with a diachronic presentation of the French past tense system focusing on present areas of competition and developments that emphasize the complexity of the system to be acquired. The concepts of time, grammatical aspect and lexical aspect (Aktionsart) are introduced and discussed in the second chapter, and a distinctive formal representation of the French past tenses is offered in the third chapter. The second part of the thesis is devoted to a corpus analysis. The data gathering procedures and the choice of tasks (oral and written film narratives based on Modern Times, cloze tests and acceptability judgement tests) are described and justified in the research methodology chapter. The research design was shaped by previous studies and consequently allows comparison with these. The second chapter is devoted to the narratives analysis and the third to the grammatical tasks. This section closes with a summary of discoveries and a comparison with previous results. The conclusion addresses the initial research questions in the light of both theory and practice. It shows that the PAH fails to account for the complex phenomenon of past tense development in the acquisitional settings under study, as it adopts a local (the verb phrase) and linear (steady progression towards native usage) approach. It is thus suggested that past tense acquisition rather follows a pendular development as learners reformulate their learning hypotheses and become increasingly able to shift from local to global cues and so to integrate the influence of cotext and context in their tense choice.

This case study follows eleven non-English speaking students as they adapt to community college, content courses. The three classes examined are required freshman classes--Humanities, Social Environment, and Individual in Transition. In order to cope with the demands of these classes, students must penetrate the academic discourse community and have effective relationships with their instructors and their peers. The results of the study are based on interviews with eleven non-native speaking (NNS) students and their instructors and on an analysis of student writing assignments, course syllabi, and exams. Three general areas are examined: (a) students' first-language (L$\sb1$) education, (b) the requirements of their content classes, and (c) the affective factors which influence their adaptation process.^ The case of these students reveals that: (1) Students draw on their L$\sb1$ education, especially in terms of content, as they cope with the demands of these content classes. (2) In some areas L$\sb1$ educational experiences interfere with students' ability to adapt. (3) The content classes require students to have well developed reading, writing, oral, and aural skills. (4) Students must use higher level cognitive skills to be successful in content classes. (5) Affective factors play a role in students' success in content classes. The discussion section includes possible implications of this data for college level English as a Second Language courses. ^

Antiophidic activity from decoct of Jatropha gossypiifolia L. leaves against Bothrops jararaca venom. Snakebites are a serious worldwide public health problem. In Latin America, about 90 % of accidents are attributed to snakes from Bothrops genus. Currently, the main available treatment is the antivenom serum therapy, which has some disadvantages such as inability to neutralize local effects, risk of immunological reactions, high cost and difficult access in some regions. In this context, the search for alternative therapies to treat snakebites is relevant. Jatropha gossypiifolia L., a medicinal plant popularly known in Brazil as “pinhão-roxo”, is very used in folk medicine as antiophidic. So, the aim of this study is to evaluate the antiophidic properties of this species against enzymatic and biological activities from Bothrops jararaca snake venom. The aqueous leaf extract of J. gossypiifolia was prepared by decoction. The inhibition studies were performed in vitro, by pre-incubation of a fixed amount of venom with different amounts of extract from J. gossypiifolia for 60 min at 37 °C, and in vivo, through oral or intraperitoneal treatment of animals, in different doses, 60 min before venom injection. The proteolytic activity upon azocasein was efficiently inhibited, indicating inhibitory action upon metalloproteinases (SVMPs) and/or serine proteases (SVSPs). The extract inhibited the fibrinogenolytic activity, which was also confirmed by zymography, where it was possible to observe that the extract preferentially inhibits fibrinogenolytic enzymes of 26 and 28 kDa. The coagulant activity upon fibrinogen and plasma were significantly inhibited, suggesting an inhibitory action upon thrombin-like enzymes (SVTLEs), as well as upon clotting factor activators toxins. The extract prolonged the activated partial thromboplastin time (aPTT), suggesting an inhibitory action toward not only to SVTLEs, but also against endogenous thrombin. The defibrinogenating activity in vivo was efficiently inhibited by the extract on oral route, confirming the previous results. The local hemorrhagic activity was also significantly inhibited by oral route, indicating an inhibitory action upon SVMPs. The phospholipase activity in vitro was not inhibited. Nevertheless, the edematogenic and myotoxic activities were efficiently inhibited, by oral and intraperitoneal route, which may indicate an inhibitory effect of the extract upon Lys49 phospholipase (PLA2) and/ or SVMPs, or also an anti-inflammatory action against endogenous chemical mediators. Regarding the possible action mechanism, was observed that the extract did not presented proteolytic activity, however, presented protein precipitating action. In addition, the extract showed significant antioxidant activity in different models, which could justify, at least partially, the antiophidic activity presented. The metal chelating action presented by extract could be correlated with SVMPs inhibition, once these enzymes are metal-dependent. The phytochemical analysis revealed the presence of sugars, alkaloids, flavonoids, tannins, terpenes and/or steroids and proteins, from which the flavonoids could be pointed as major compounds, based on chromatographic profile obtained by thin layer chromatography (TLC). In conclusion, the results demonstrate that the J. gossypiifolia leaves decoct present potential antiophidic activity, including action upon snakebite local effects, suggesting that this species may be used as a new source of bioactive molecules against bothropic venom.

In recent decades, debates have intensified about (auto) biographical narratives as devices of socio-educational practices, aligned to the educational setting of the XXI century which have stimulated a new educational perspective woven with epistemological and methodological training throughout life. Towards that scenario, the continued training in Judicial School has occupied important space for constitutional effectiveness and, on the other hand, has grown the demands of expanding knowledge and enhancing training practices, in turn, judicial practices. The aim is to analyze the reflective Group through "Professional Training biographical Workshop" with Bailiffs such as socio-educational practices in socio Judicial School, in the city of Natal /RN. It has highlighted the questions that guided this study: 1. What paths of experiences and knowledge shared by the Law Officials, Federal Appraisers in "Professional Training biographical Workshop" as reflective Group? 2. How is organized the reflective Group as practice in socio-professional training setting? 3. What contributions narratives of themselves bring to the bailiff in reflective Group on Judicial School? The theoretical assumptions are supported in the lifelong training in methodological and epistemological dimension of (auto) biographical knowledge (JOSSO, 2008, 2010, 2012; PINEAU, 2005, 2006; DOMINICÉ, 2010; DELORY-MOMBERGER, 2006, 2008; FREIRE, 1987, 1996, 2001; PASSEGGI, 2008; 2010; 2011; 2012). In 2009, 09 (nine) civil servants in post of Federal Appraiser Justice Official, law graduates participated in this research through eight (08) "Biographical Workshops of Professional Training", consisting of biographical practices and scenarios, enabling oral and written narratives about a memory that has meaning, relationship and tessituras between files, facts and feelings that reveal the perception of self and other, as well as mobilize and weave the training process. The experiences of speaking, writing and reading were constituted of spaces that facilitating the reconstruction of the trajectory of training and career awareness-making, helping to re-signify labor relations and lead to their own professional design. From this study, the reflective properties of groups have emerged, consisting of Reflexivity, Experience, Historicity, Reversibility, dialog and formability processes, with paths to social and educational practices in which professionals identify the meaning and significance of self and of the profession that are exercising. The expectation is to continue with the spirit of research to emerge from the participants responses to training practices in Judicial School, aligned with the new knowledge of understanding the human being, not only an object of his work, but also a social subject, co-participant in the process of re-signifying life and work in a permanent way.

Why students of 6th year still present oral marks in written? To answer this question our paper presents what they are and how writing and grammatical deviations occur and emerged in an attempt to expand on these studies. The same objective to evaluate the presence of these deviations in genres produced by students of the 6th year of the Municipal School Manoel Catarino Filho and check if there are more variation deviations or grammatical deviations. It also aims to improve the linguistic and discursive ability of students in various traffic environments of certain genres and consequently the formation of active readers and writers. In order to better understand how this process occurs, the text starts of the socio discursive conception of gender, with the theoretical background studies of Bakhtin (1992) and Marcuschi (2002) about this conception and the rhetoric conception of Aristoteles and Platão. The text underlies even the works of Callou (2007), Neves (2003), Faraco (2002), Franchi (2006) and Cagliari (2005) on the Grammar School, linguistic variation as also on the sociolinguistic parameters as well in research on the phonetics and phonology of Oliveira e Nascimento (1990), Seara (2009), Hora (2009) and in the PCN. To compose the corpus of this study we collected 23 texts produced by students to serve as a data source for analysis of the presented deviations by quantitative and qualitative research method, in which categorize the deviations found in two groups: oral and linguistic variation deviations and writing and grammar deviations. The results showed that there was a rate of occurrence of oral and variation deviations greater of writing and grammar deviations. We concluded that the orality has a great influence on the written production of students. Finally, we propose some activities aimed at minimizing the occurrence of deviations in written productions of the students.

The little interest in reading and the large presence of deviations in writing observed in the texts of students of the 5th grade of a public school in RN, led us to question the motives of this problem. Thus, the idea to organize and develop teaching sequences with a variety of possibilities of reading and production through the text genres. The practice with the textual genres in elementary school extends the use of reading and writing and improves the quality of learning. In this way, the school, as one of the most active spheres in social practices of the language, we justify this work with the use of text genres as facilitators for teaching and learning the mother tongue. For this purpose, we draw as the main objective to talk about the work with textual genres from the development of didactic sequences, as well as encourage students to take a more reflexive attitude toward language and its uses, as discursive social practices. The development of the study with the text genres was made through the application of didactic sequences in the school context of elementary school classes, from 5th grade. Specifically were chosen, the letter, note, music, poetry, fable and the tale. The study is anchored in the reflections of the following theorists and researchers: Bakhtin (2011), Miller (1994), Marcuschi (2008) and Bronckart (1999) on the text genres; Marcuschi (2005) and Dolz and Schneuwly (2004) that approve a teaching-learning proposal focused on textual genres, giving a meaning to language in the construction of the knowledge and Dolz and Schneuwly (2004) regarding the didactic sequence; other theoretical orientations: PCN (1998), Lerner (2005), among others. The methodology followed the action research guidelines, in a qualitative approach perspective. The instruments of research included questionnaire, observations, readings and productions. The results pointed the students' interest in relation to the activities developed in the didactic sequences and consequently improvement in the students‘ own writings. In this sense, we reiterate the need to contamplate in the teaching activities the diversity of texts and genres and, not only due to its social relevance, therefore the student should be able to use the language in various way and adapt their texts to situations of oral and written interlocution.

The search for new meanings in the basic education teaching-learning process has caused the development of public policies for mother language teaching, such as the Portuguese Language Olympics (OLP). To contribute to this search, this intervention project has as object of study reading and writing practices developed in the OLP through the educational model arising from literacy projects (TINOCO, 2008). In working towards, the general aim of reframing reading and writing practices through the PLO, developed from the teaching model that comes of literacy projects, we established three specific objectives: a) reflect on a national writing contest; b) to realign conceptual and methodological the Portuguese classes of the 7th grade school due to the developed project; c) to improve the reading and writing practices of the students in 7th grade of school where we operate. Therefore, we base ourselves in the history of Portuguese teaching in Brazil (SOARES, 2002; GERALDI, 2008), the dialogical conception of language (BAKHTIN, VOLOCHÍNOV [1929] 2009; SOARES, 1998; FARACO, 2009) in Literacy Studies (KLEIMAN, 2001, 2005, 2006; TINOCO, 2008; OLIVEIRA; TINOCO; SANTOS, 2011; STREET, 2014), the learning community concept (AFONSO, 2001), in studies of retextualization (OLIVEIRA, 2005; MARCUSCHI, 2010), gender discursive literary memories (CLARA; ALTENFELDER; ALMEIDA, 20--), in written evidence (POSSENTI, 2002) and Textual Linguistics (MARCUSCHI, 2008; ANTUNES, 2009; KOCH, 2011; SILVA [et. al.], 2013). Methodologically, this qualitative research (LÜDKE; ANDRÉ, 1986; ANDRÉ, 2005) is anchored in Applied Linguistics (MOITA LOPES, 1996). This research was supporting by students in the 7th grade, teachers, management team and parents, as well as people outside of school community. The instruments used for the generation of data were semi-structured interview, students‟ texts, audio recordings and video, photos, OLP material (teacher's book, a collection of texts and CD-ROM). The data generated allowed us to establish the following categories of analysis in relation to the texts produced: authorship, in formativeness, discursive progression, compositional structure, content, style, and language aspects. In addition, throughout the project, the collaborators have produced texts of various genres: oral interview and written request letter, legal, literary memories, oral and experience report. Also experienced a local award and participated in a national competition. They produced a video and a book with stories and student authorship of illustrations. The results achieved show that the literacy project developed also allowed macro changes: reading and writing practices, once considered strictly school studied, they were transformed into broader social practices, through which various literacy agents were able to collaboratively act. In short, they experienced writing practices that go beyond the classroom and the teacher-student relationship.

Teaching Portuguese language in Brazilian public schools is still limited mostly to studying decontextualized text fragments, memorizing classifications and cult of grammar rules. Considering the language as a social, cultural practice which emerges from the intersubjective interaction, we sought to propose an educational intervention that prioritizes the retextualization processes from speech to the writing of memoirs as a textual genre, so as to contribute for improving learner’s discursive performances. Therefore, paying attention to these concerns and in attempt to contribute for improving the teaching of Portuguese language in elementary school, we chose as privileged locus a 9th grade class from a state school in Bento Fernandes, RN. The corpus is formed by texts produced and retextualized by students from the elders’ oral reports within local community. We sought thus to understand what memory is, its importance for registering local spoken language and culture, as much as to carry out didactic actions that favor students’ learning in the activities of textual production. In light of the theoretical overviews about linguistic-discursive relations, based on Marcuschi’s (1993, 1997, 2001, 2002, 2006, 2008, 2010) conception of oralitiy-writing continuum and the debates proposed by Antunes (2003, 2014), Alves Filho (2011), Koch (2012) and Bakhtin (1992, 2011), we aimed to understand, by analyzing the retextualized memoirs, how these practices complement each other within the process of orality and writing. As for the proposal of didactic sequences, the study has been oriented by Dolz and Scheneuely (2004); as for the memoirs, by the guidelines of Coracine and Ghiraldelo (2011) and Le Goff (2010, 2013). In this way, this work followed the action-research methodology in a qualitative approach, considering the teacher (researcher) as an active agent involved in the process of knowledge production in his own educational practice, so as to interfere in the mediation, knowledge production and its dissemination in classroom context, which is the privileged locus for constructing and transforming process. There is much to be research within the area of retextualization. Yet we verified that this educational intervention, based on discursive operators of retextualization, has been proven viable as an efficient path so that we teachers can work the peculiarities of usages and functions of textual genres in oral and written modalities of a language, without grasping both as a dichotomy. This accredited us to strengthen a discourse that undoes many myths still present in that order, especially the one that causes more damage for the learners of Portuguese language – that writing is a representation of speech.

This research investigated the nasality of vowels in the spontaneous speech of inhabitants of the quilombola communities of Brejo dos Crioulos and Poções (MG). As a theoretical framework, we based on the assumptions of Phonetics and Phonology, in renowned scholars on the investigation of nasality (CAGLIARI, 1977; CÂMARA JR., 1984, 2013; BISOL, 2013; ABAURRE; PAGOTTO, 1996; SILVA, 2015), with subsidies of the Corpus Linguistics. Its general goal was to investigate the occurrence of nasality, in the dialect of these quilombola communities, and their linguistic behavior, considering the linguistic factors that can interfere in the phenomenon. Specifically it was aimed to a) detect the occurrence of nasalized vowels with the help of the resources that the Corpus Linguistics provides (Praat and WorldSmith Tolls); b) discriminate the different types of occurring contexts of nasalized vowels; c) make quantitative and qualitative analyzes of the nasalized vowels in the study corpus; d) describe and analyze the behavior of nasalized vowels and; e) contrast the values of F1 and F2 of the oral and nasalized vowels. It was hypothesized that the nasality happens because it is conditioned by the nasal segment following the nasalized vowel - phonological process of “assimilation” - its position as the primary stress and grammatical category. It was believed that the quilombolas communities of Brejo dos Crioulos and Poções produce nasalized vowels in their speech and this linguistic phenomenon is favored by the adjacent presence of consonants or nasal vowels. Furthermore, it was hypothesized that the values of F1 and F2 of oral and nasalized vowels in these communities are distinct. The following research questions were elaborated: (i) is the presence of nasalized vowels in the speech of these quilombola communities conditioned to the presence of a nasal sound segment? (ii) does the nasal sound segment following the nasalized vowel favor the occurrence of the nasality phenomenon? is there a difference between the values of F1 and F2 of the oral and nasalized vowels in both quilombola communities considered? To compose our corpus, 24 interviews recordings were used (12 female speakers and 12 male speakers), a total of 24 participants. It was found that the following nasal sound segment tends to condition the nasalized vowel. In general, it assimilates the lowering of the soft palate of nasal consonant segment immediately following, but there are cases of nasal vowel segment - regressive assimilation; the stressed syllable tends to favor the nasality, but it occurs in pretonic and postonic position as well; F1 and F2 values of oral and nasalized vowels in the quilombola communities of Poções and Brejo dos Crioulos are distinct: the group of Brejo dos Crioulos tends to produce the F1 of oral and nasalized vowels more lowered than the group of Poções and the F2, in a more anterior position. The nasality tends to occur in verbs and nouns, although it is not specific to a grammatical category. This research found cases of spurious nasalization, confirming previous studies. In turn, it revealed cases of lexical items with favorable context for nasalization, but with its non-occurrence. This last case, considered as the lowering of the uniform soft palate in PB, presented pronounced vowels without the soft palate lowering. That is, it was detected variation in the phenomenon of nasalization in PB. With this work, it was promoted the discussion about nasality, in order to contribute to the linguistic studies about the functioning of Brazilian Portuguese in this geographical context.

Telenovela’s orality: from medium to a linguistic-discursive construction. Studies about telenovelas usually highlight their "orality". However, a literature review, specifically for Latin American telenovelas, shows that the term "orality" has been used with varying senses. In contrast with those devoted to telenovelas, literary studies have addressed the question by conceptualizing it as fictional orality. This paper takes fictional orality as a key concept to explain telenovela’s discursive peculiarities, and on that base, it distinguishes several dimensions of linguistic and discursive variation, in which such orality is being portrayed.
