Abstract: this paper presents a possible solution to the problems aroused by the understanding of the delusional phenomenon according to the model of a restricted theory of absolute reference in which the words and, consequently, the judgements, correspond to the things as a logical alphabet. in the pragmatic conception adopted here, language is taken as a game guided by rules in which effective discursive cooperation is more important than the ideal meaning of expressions. in this sense, the theory of acts of speech seems to be the best solution offered by the philosophical pragmatics and it is used as a methodological principle on the analysis of speech excerpts of delusional patients. delusion shows itself as an original solution to decisive questions in the history of a psychotic person.
O delírio à luz da teoria dos atos de fala

Abstract: Este trabalho apresenta uma possível solu o para problemas suscitados pelo entendimento do fen meno delirante segundo o modelo de uma teoria restrita da referência absoluta, na qual as palavras e, consequentemente, os juízos, corresponderiam às coisas como um alfabeto lógico. Na concep o pragmática aqui adotada, a linguagem é tomada por um jogo regido por regras em que é mais importante a eficácia da coopera o discursiva que o significado ideal das express es. A teoria dos atos de fala se mostra a mais bem acabada solu o da pragmática filosófica nesse sentido e é usada como princípio metodológico na análise dos excertos de fala de pacientes delirantes que constituem os corpus discursivos. O delírio termina por se mostrar como uma solu o inédita para quest es cruciais da história do indivíduo psicótico.

Abstract: the aim of the present paper is to describe the nature of delusion according to a theory of reference. the category of reference is investigated based in the analytical philosophy of language and in psychopathology. all theoretical reflection begins with the analysis of speech excerpts of psychotic patients and it is verified that psychotic thought is distinguished by the breaking of the usual process of referentiation. it is shown the insufficiency of conceiving delusion as only a judicative mistake and the necessity on considering delusional propositions under the more ample contexts of ordinary language and so clear up its specificity.

Psicologia: Reflex?o e Crítica , 1999,
Abstract: O esclarecimento da natureza do delírio conforme uma teoria da referência é o objetivo desse trabalho. A categoria da referência é investigada à luz da filosofia analítica da linguagem e da psicopatologia. Toda a reflex o teórica se desenvolve a partir da análise de excertos da fala de pacientes psicóticos e constata-se que o pensamento psicótico é caracterizado pela quebra do processo habitual de referencia o. é demonstrada a insuficiência de se conceber o delírio como apenas um erro judicativo e a necessidade de considerar as asser es delirantes dentro dos contextos mais amplos da linguagem ordinária e assim evidenciar a sua especificidade.

Abstract: lettuce production in hydroponic system presents growing expansion in brazil, but still there are problems of quality and risk of nitrate accumulation. this work was carried out to evaluate the lettuce production and nitrate accumulation in hydroponic system depending on the increasing levels of nitrogen in the nutrient solution. the experiment was conducted in greenhouse of the universidade federal da paraíba, brazil. the lettuce plants were grown in nutrient solution containing increasing levels of n (11, 13, 15, 17, 19 and 21 mmol l-1) during a 25-day period. an entirely randomized design with four replications was used. plant total yield (ptt), plant commercial yield (pcm) and nitrate contents in the fresh matter of roots, stems and leaves of the lettuce were evaluated. there were no significant effects of increasing levels of n in nutrient solution on ptt and pcm, average values of 357.3 and 352.5 g/plant being observed, respectively. the increased levels of n in nutrient solution increased linearly nitrate content on all lettuce parts. the nitrate content reached 659, 623 and 615 mg/kg in the fresh matter of roots, stems and leaves, respectively, at the highest n level. nevertheless, the maximum nitrate content observed in leaves was far below the risk level for human health.

Abstract: phosphorus is an important mineral nutrient for vegetables. this work was conducted at universidade federal da paraíba, in areia, brazil, from december/2001 to july/2002, aiming to evaluate the effect of levels of p2o5 on the yield of lima bean, cv. "orelha de vó". the experimental design was a randomized block with five treatments (0; 100; 200; 300; 400 and 500 kg ha-1 of p2 o5), and four replications. each plot consisted of 40 plants spaced 1.0 m between rows and 0.50 m between plants in each row. the estimated maximum yield of green and dry beans (5.2 and 2.7 t ha-1, respectively) corresponded, to the dosages of 309 and 302 kg ha-1 of p2o5. the levels 291 kg ha-1 and 281 kg ha-1 of p2o5 provided, respectively, the greater economic return for the yield of green (4.1 t ha-1) and dry (1.8 t ha-1) beans. the most economic levels included more than 80% of those dosages responsible for the maximum yields and indicated the economic viability of phosphorus utilization on lima bean crop. the p2o5 levels which promoted the maximum yield and the maximum economic return for green and dry beans yield were respectively, with 57.1; 56.3; 55.0 and 53.8 mg dm-3 of available p for the extractor of melich 1. the lima bean response to the phosphorus fertilization in soils with similar fertility used in the present study, for green and dry beans yield, will be reduced at levels of available p superior to 55.0 and 53.8 mg dm-3. the average concentration of p in the leaves of lima bean, 120 days after sowing, in function of levels of p2o5 was of 3.4 g kg-1. for the soil of this study the application of 291 and 281 kg ha-1 of p2o5 is more recommended to establish the lima bean respectively, for green and dry beans yield.

Abstract: lettuce is one of the leading vegetables in brazil. however, studies concerning its fertilization for the northeastern region of the country are still scarce. this work was carried out to evaluate the effects of mineral nitrogen supply and organic fertilization on the production and nitrate accumulation in lettuce, cultivar elba, in the semi-arid zone of paraíba, brazil. a randomized block design, with four replications, was used to test five doses of cattle manure (30; 60; 90; 120, and 150 t ha-1), five doses of n supplied as urea (30; 60; 90; 120, and 150 kg ha-1), and a control without fertilization. along with mineral n, the other nutrients were also supplied using mineral sources. no additional nutrients were supplied where organic fertilization was used. lettuce yield was significantly higher when organic fertilization was used, compared to the mineral nutrient supply. taking into account most of the fertilization doses recommended for growing lettuce in the brazilian northeastern states, n mineral fertilization in sandy soils with low organic matter contents can be fully replaced by organic fertilization with cattle manure. plant total (pty) and commercial yield (pcy) as affected by the mineral n supply fitted into a quadratic model, in which the doses 94.5 and 95.7 kg ha-1 corresponded to respectively the highest pty (381.9 g plant-1) and pcy (321.6 g plant-1). where organic fertilization was used, pty and pcy fitted into a linear model. therefore, the highest pty (523.9 g plant-1) and pcy (449.48 g plant-1) were observed at the highest manure doses. nitrate content on roots, stems, and leaves increased linearly with nitrogen and manure application. in roots, the nitrate content (mg kg-1 of fresh matter) reached 93.96 (n mineral (nm)) and 65.09 (organic fertilization (of)); in stems, 183.45 (nm) and 98.22 (of); and in leaves, 121.98 (nm) and 75.62 (of). the maximum nitrate content observed in leaves was far below the risk level for human health.

Abstract: introduction: colorectal cancer is the most common tumor in the developed countries, and the number of new cases annualy is aproximately equal for men and women. several environmental factors can interact in all steps of carcinogenesis. lately the balance between genetic predisposition and these factors, including nutritional components and lifestyle behaviors, determines individual susceptibility to develop colorectal cancer. the aim of this study is to revise the references about lifestyle include diet, physical exercise, tobacco smoking and use of alcohol, and the risk of colorectal cancer in databases published during 1994-2004. dietary factors: according to the reports high intake of red meat, and particularly of processed meat and positive energetic balance (high intake of total fat and carbohydrate) was associated with a moderate but significant increase in colorectal cancer risk. convincing preventive factors include increase consumption of a wide variety of fruit and vegetable, particularly, dark-green leafy, cruciferous, a deep-yellow on tones, and fibre. lifestyle: physical activity as a means for the primary prevention of colorectal cancer. there is a probable synergic effect among physical inactivity, high energy intake and obesity and incidence of colorectal cancer. a growing body of evidence supports that avoidance overweight and the use of tobacco and alcohol is recommended to prevent colorectal cancer. conclusion: current data suggest that lifestyle modification including proper diet such as the ones rich in vegetable and poor in red meat and fat, regular physical activity and maintaining an appropriate body weight and avoiding the use of tobacco and alcohol may lead to reduce colorectal cancer risk.
