O presente trabalho teve como objetivo verificar se os sintomas incitados na bananeira cv. Nanicão, do subgrupo Cavendish, na região do Vale do Ribeira, estão relacionados com níveis de nutrientes no solo e nas folhas. Foram separadas 16 áreas na região, sendo a metade com plantas sintomáticas e a outra com plantas sadias. Nessas áreas, coletou-se a terceira folha de cinco plantas e o solo junto a essas mesmas plantas, nas profundidades de 0 a 20 cm e de 20 a 40 cm. em ambas as profundidades do solo amostrado, níveis de Ca, Mg, PO(-3)4, S e da capacidade de trocas catiônicas (CTC) foram significativamente diferentes entre as áreas, sendo que os valores baixos destes elementos estavam presentes nas áreas contendo plantas sintomáticas. em ambas as profundidades, o Mg, o Al e o H em relação à CTC foram significativamente diferentes entre as áreas, sendo que o valor baixo de Mg e alto de Al e H estava presente nas áreas com plantas sintomáticas. O N, K e S nas folhas foram significativamente diferentes entre as áreas. Estes elementos apresentaram valores baixos nas áreas contendo plantas sintomáticas. Apesar de algumas quantidades de macronutrientes do solo e das folhas estarem presentes somente nas áreas contendo plantas de Nanicão com sintomas semelhantes aos de fusariose, deve-se buscar comprovação de uma possível ocorrência da raça 4 do patógeno no Vale do Ribeira.

Com o objetivo de estudar os efeitos da calagem e da adubação fosfatada sobre o crescimento de plantas de soja e capim-marmelada e, o reflexo destas práticas nas relações de interferência entre a planta daninha e a planta cultivada. O estudo foi conduzido em casa-devegetação por um período de 49 dias. Utilizaramse vasos de 4 litros, contendo substrato retirado de um LR-distrófico. O delineamento experimental adotado foi o inteiramente casualizado, com quatro repetições. Os tratamentos foram dispostos em um esquema fatorial 2x3x4, onde tinha-se: dois níveis de calagem (presença e ausência), três condições de vegetação nos vasos (soja cultivada isolada, planta daninha cultivada isolada e a convivência das espécies) e quatro doses de aplicação de fósforo (0, 50,100 e 200 ppm) no substrato. A calagem incrementou a altura, o número de trifólios, os teores de clorofila a e b, a biomassa seca e a área foliar das plantas de soja e, proporcionou decréscimos na altura, no número de perfilhos e no acúmulo de matéria seca de plantas de capim-marmelada. A interferência imposta pelo capim-marmelada reduziu a altura de plantas, o número de trifólios , os teores de clorofila a, o acúmulo de matéria seca e a área foliar das plantasde soja. de forma oposta, a competição imposta pela soja determinou decréscimos na altura, no número de perfilhos, nos teores de clorofila a e b, no acúmulo de matéria seca e na área foliar das plantas de capim-marmelada. Já, a adubação fosfatada incrementou a altura, o número de perfilhos, o acúmulo de matéria seca e a área foliar das plantas de capim-marmelada.

O artigo analisa a posição dos Estados Unidos nas relações internacionais pós-Guerra Fria, tomando como referência as controvérsias sobre os alcances e limites da sua postura hegemônica, que adquirem maior impulso a partir da formulação da chamada doutrina Bush, sistematizada no documento A Estratégia de Segurança Nacional dos EUA. No tratamento da temática proposta, enfatizam-se os seguintes aspectos: estabelecimento de um paralelo entre a transição dos séculos XIX-XX e XX-XXI, situando as características do imperialismo de cada época; uma análise da atual política externa dos Estados Unidos, enfocando o debate entre unilateralismo e multilateralismo, com destaque para as reações geradas pela intervenção no Iraque; uma discussão crítica das abordagens que visualizam na agenda de segurança da administração Bush um indicador de perda de hegemonia, que imporia a substituição da busca do consenso pela dominação aberta.

Este estudio investigó las actitudes y creencias de los estudiantes universitarios en Ciencias Químicas por la Universidad de Río Grande do Norte (UERN) como un paso hacia la elaboración de una propuesta de material didáctico para el estudio de las relaciones CTSA en la licenciatura en química. Para el conocimiento de las actitudes y creencias fue utilizado dos instrumentos (Escala Likert y un cuestionario), que proporcionó un análisis dentro del nuevo paradigma de investigación (cuantitativa y cualitativa) en la Enseñanza de la Ciencia y Matemáticas. Los resultados mostraron que los estudiantes de licenciatura en química tienen creencias positivistas y que suelen son considerados por algunos como ingenuas, como la creencia en el modelo de decisión tecnocrática, la linealidad del desarrollo científico y tecnológico que lleva a el bienestar social y neutralidad de los conocimientos científicotecnológico. Basándose en estos datos y la literatura sobre el tema se elaboraron tres módulos de aprendizaje: a) Cuestionando la hegemonía del conocimiento técnico y científico, b) Las relaciones entre ciencia, tecnología, sociedad y medio ambiente - las relaciones CTSA c) Propuesta de temática para la enseñanza de la química en una perspectiva de CTSA: El Río Mossoró. Por último, el material producido se utilizó en dos cursos ocurridos en el Campus Central en el Centro de Educación Superior en São Miguel, ambos de UERN. Los participantes expresaron su aprobación al enfoque trajo de el experimento propuesto y de el caso de simulación contenidos en la propuesta de

In this study we investigate the reference to other s discourse done it through the resource of direct cited discourse at background section in monographic texts produced by university students at the last phase of final work in their graduate Letras course. This work is guided in cited/related discourse studies in Bakhtin (2004), Authier-Revuz (1990, 1998, 2004), Maingueneau (1996, 2002), Charaudeau and Maingueneau (2004); in genre approaches developed by Bakhtin (2000); Maingueneau (1996, 2002); socio-discursive interaction (BRONCKART, 1999, 2003; SCHNEUWLY, 2004; DOLZ e SCHNEUWLY, 2004) and Bazerman (2005); and also in presuppositions of Textual Linguistics presented by Charrolles (1988), Van Dijk (1997), Beaugrande and Dressier (1981), Koch and Travaglia (1993, 1995), Koch (2002, 2004) and Val (2000, 2004). We have established as aims to analyze and interpret meaning relations problems in how to articulate direct cited discourse with citing discourse and at the same time explain semantic implications that comes from that articulation that compromise text meaning, at background section in that monographic genre. The analysis, by qualitative and quantitative basis in eleven monographic works that form our corpus, gave us the opportunity to achieve and see that meaning relationships in the articulation of direct cited discourse with citing discourse show problems that may be categorized into three different groups: problems related to meaning relationships with citing discourse that comes before it, problems of meaning relationships with citing discourse that comes after it, and problems with of meaning relationships with citing discourse that come before it and at the same time with citing discourse that comes after it (i.e. in relation to both). These analysis also allow us assert that, these problems, just because they occur frequently, they affect the micro level text coherence, and they also compromise the text global meaning. The results show that students at Letras Course, even in the ending process of their course do not show the real domain in relation to some ways of direct cited discourse organization and working, and also how the ideas articulation work in the construction of relations between direct cited discourse and the citing discourse that can turn those students able to produce a text that enhance acceptable patterns

This work is inserted to Applied Linguistic studies, concerned to the understanding that language is a social practice, bringing a qualitative research, discussing essential aspects that involve the subject and his/her discursive practice: signification and valuation. Due to this, we have elected as subject study, the sense and values attributed to the verbs make out and date searched on the articles written in the Vestibular 2005 process promoted by the Universidade Federal do Rio Grande do Norte (UFRN), that had the following instruction: In a relationship, is it better make out , just date , or, both, make out and date ? This research is based on the Circle of Bakhtin s dialogic theory, as well as in the notions of instability in the affective relationships nowadays and in the individualization and multiplicity of contemporaneous subjectivity. Those papers are important to analyze the meaning and values that the verbs make out and date present, nowadays, as expressions of an affective relationship and how this situation can interfere in the positions of subjectivity in a formal instance as a vestibular. Those textual productions reflect those relationships, confronting temporary ones, whose discuss is marked, in general, by social voices that evaluate to make out negatively and to date positively

This research investigates the discursive constitution of identities; in spe-cial, it aim to problematize women identities constitution, pointing discursive prac-tices and power relations which involve them. The interviewed subjects had been adult women who had resumed their school trajectory, after certain period without frequenting educational establishments. Aware of that those identities can be per-ceived through the observations of the discursive practices, we question: which discursive practices and power relations involve and constitute those women? Which identity positionings they take through the discursive practices and power relations that include them and that are identified in their stories? Which linguistic marks characterize, in the speech of those women, forms of resistance in the con-stitution of identities? We intend to investigate the constitution of woman identities in the contemporanity; pointing discursive practices and power relations which in-volve women that converge to their identity constitution; exploring in the linguistic materiality effects of senses that emanate of the discursive practices and power relations which involve the collaborators in the identity constitution in private and public spaces. Research corpus is composed by stories of life granted by three women, collected through semidirected interview between 2004 and 2005. To ana-lyze the data, we base in authors as Pêcheux (1993; 2002), Foucault (1979; 1988; etc.), Butler (2003), Scott (1992; 1995), Hall (2000; 2004; 2005), Bauman (1999; 2005), among others that problematize questions as discourse, identity, social gender, power and its interfaces. The life stories had allowed to analyze: the gen-der identity constitution from discursive practices and relations of forces lived in the familiar scenery; assumed identity positionings from discursive practices in globalized urban contexts; power positions in the domestic and extradomestic sphere and new identity positionings

The present work seeks essentially to demonstrate how some anthropological structures of the imaginary, theorized by the French thinker Gilbert DURAND, projected themselves in a noticeable manner in the poetic work of the Brazilian poet Orides FONTELA. Chiefly we will demonstrate with great care in what way this projection and vivification occur through an imagination that not only materializes some fundamental archetypes of the human imagination, but also seeks to organize them through original poems in its form of presenting the poetic discourse, giving here a different contribution of the mythical or religious discourse, privileged places, since always, where the symbolic functions also manifest themselves

This research aims to understand the relationship between media, capitalism and ownership of free time for leisure practices in industrial societies and postindustrial. Searching is thus a conceptual framework that takes into account the kind of ideology that naturalizes the relationship of leisure with the foundations of contemporary media, and the media only with leisure, forgetting their insertion in the labor and industrial relations in society. We intend to demonstrate that every mode of production, in the capitalist system, entails a mode of reproduction. Methodologically, this is a first approximation, from theoretical concerns already performed, constituting a theoretical research, bibliographic and descriptive character. The results of the text drives us to the conclusion that the work and leisure spheres tend to be less and less differentiated, since both remain as activities of product management with the same intellective protocols, based on information and communication technology, and that accordingly, the media favors an expansion of productive activity even during leisure time

This work deals with the relationship between medicine and philosophy, which has existed since Antiquity, and will also be discussed here from Kant s perspective. It presents the historical context formed by reciprocal influences of common notions regarding health/disease, balance/justice, and just measure, which are present in the medical discourse as much as in the philosophical one. It considers that Hippocratic medicine emerges from concerns about dietetics, thus creating the link between philosophy and medicine, which is important for our analysis on Kant s contributions to Hippocratic legacy. Taking into account these considerations, the work distinguishes between two aspects which are associated within the dietetics presented by Kant in his work The conflict of the faculties, studied here in the light of his Doctrine of virtue, particularly the duties to oneself in regard the care of one s body and the teleological conception. In this sense, the work indicates the role of Kantian thinking not only to enrich medical dietetics, by lending to it moral value, but also to enrich philosophy by highlighting its therapeutic effects

Several studies on nonhuman primates show that the relationships between individuals strongly influence the expression of cooperative behavior, both in natural environment and in captivity settings. Recent studies suggest that cooperative breeders present outstanding performance in tasks involving social cognition, such as cooperative tasks with experimental apparatuses. In experimental research on this subject it is crucial to differentiate between real cooperation (or communicative cooperation, mediated by social attention) and by-product cooperation that results from simultaneous actions of individuals. The present study assessed, in Callithrix jacchus, a cooperative breeder species, if social relationships and social attention between subjects are important factors during performance in cooperative tasks. During the experimental procedure the animals participated in three different cooperative tasks: cooperation task, prosocial task and control task. Diverging from the literature, matrix correlation tests revealed no significant relationship between grooming or proximity and the execution of the tasks, suggesting that other factors such as age or hierarchy may have an effect on the performance in cooperative tasks in this species. There was also no relationship between the execution of the cooperative tasks and social glances, suggesting that there was no social attention during the tasks. Moreover, there were lower rates of social glances in the cooperative tasks as opposed to the control tasks. However, the small number of pulls in prosocial tasks suggests that the animals distinguished between tasks that benefited only a partner and tasks that generated benefits to themselves, choosing the latter. We conclude that, for the tasks presented in this study, we could neither detect the role of social relationships on the cooperative tasks nor assert that there were true cooperation and prosocial behavior
