O direito como fato social
José Carlos Vieira
Semina : Ciências Sociais e Humanas , 1988, DOI: 10.5433/
Abstract: In this word the intent is to demonstrate that law is always a verifiable phenomenon with social reality, thus a social fact. Law as a scientific object can be studied in three dimensions: through philosophy of law, through the "dogmatic-normative" science of law and through sociological justice. Miguel Reale, creator of the "three dimensional theory of law", affirms that law is, as the same time, fact, value and norm. Following this theory, various considerations can be developed, parallel with the "critical theory", defended by Luiz Fernando Coelho, who sees law as an instrument for radical social change and not simply a regulator of established social order. The development of this theme was exhaustively investigated during the classes of philosophy of law, part of the program for the Masters Degree in Law of Social Relations at the Universidade Estadual de Londrina and this paper is synthesis of our development. Pretende-se demonstrar, neste trabalho, que o direito é sempre um fen meno verificável na realidade social; é um fato social, portanto. O direito, como objeto científico, pode ser estudado sob três dimens es: através da filosofia do direito, da ciência dogmática-normativista do direito e da sociologia jurídica. MIGUEL REALE, o conceituado jus-filósofo paulista, criador da "Teoria tridimensional do Direito", afirma que o direito é, ao mesmo tempo, fato, valor e norma; sobre esta teoria, s o desenvolvidas várias considera es, em cotejo com a "Teoria crítica”, defendida por LUIZ FERNANDO COELHO, que vê o direito como instrumento de muta o social e n o, simplesmente, um regulador da ordem social estabelecida. A abordagem deste tema foi exaustivamente trabalhada durante as aulas de Filosofia do Direito, no Curso de Mestrado em Direito das Rela es Sociais da UEL e este trabalho procura sintetizar os conhecimentos auridos.
Aspectos constitucionais do direito agrário emenda constitucional N° 10/64

Semina : Ciências Sociais e Humanas , 1988, DOI: 10.5433/
Abstract: This paper, presents a brief history of the constitutional work applied to property rights in Brazil, mainly to those regarding land property. lt also shows the development of agrarian rights as an independent branch of the juridical prescription up to its effective recognition. It slightly shows the important role of the social function of property in constitutional texts as to support governmental actions aiming at an agrarian reform, and any other tendency to alter the rural profile of the country. This work is aimed to show that, despite a set of laws related to the agrarian reality of this country, the facts and data make it clear that nothing has been done about it up to today. The research Our constitutional texts shows that some advances towards the effectiveness of the social function of property principles have been made; nevertheless, the constitution to be promulgated by the year 1988, surprisingly takes a step backwards as to this chapter for it decreases the scope that it had in former constitutions and even in the original ones by authoritarian governments. O presente trabalho contém um resumo histórico do tratamento constitucional reservado ao direito de propriedade no Brasil, especialmente à propriedade da terra, bem assim a evolu o do direito agrário como ramo aut nomo do ordenamento jurídico, até o seu efetivo reconhecimento como tal. Registra, mesmo que rapidamente, a importancia que teve a adota o do princípio da "fun o social da propriedade" nos textos constitucionais, de forma a respaldar a es governamentais objetivando a realiza o da reforma agrária e outras medidas tendentes a alterar o perfil rural do país. O trabalho procura mostrar, também, que, malgrado dispor o pais de um rol de leis capazes de dar suporte a propostas destinadas a promover uma efetiva mudan a na realidade agrária, os fatos demonstram claramente que isto n o ocorreu até hoje. A pesquisa nos textos constitucionais mostra que alguns avan os em dire o à efetiva o do princípio da "fun o social da propriedade", foram dados, ainda que de forma pragmática, mas que, surpreendentemente, a Constitui o que se pretende promulgar neste ano de 1988, neste capítulo, marca um retrocesso, pois reduz a amplitude que o mesmo teve nas constitui es anteriores, até mesmo naquelas outorgadas por governos autoritários.

Abstract: objective: to determine the oxygen outflow delivered by seven different models of manually operated self-inflating resuscitation bags (with and without an oxygen reservoir connected), which were tested using different oxygen supply rates without manipulating the bag, by simulating their use in patients breathing spontaneously. methods: the oxygen outflow was measured using a wall oxygen flow meter and a flow meter/respirometer attached to the bag, together with another flow meter/respirometer attached to the patient connection port. the resuscitation bags that allow the connection of an oxygen reservoir were tested with and without this device. all resuscitation bags were tested using oxygen supply rates of 1, 5, 10, and 15 l/min. statistical analyses were performed using analysis of variance and t-tests. results: the resuscitation bags that allow the connection of an oxygen reservoir presented a greater oxygen outflow when this device was connected. all resuscitation bags delivered a greater oxygen outflow when receiving oxygen at a rate of 15 l/min. however, not all models delivered a sufficient oxygen outflow even when the two previous conditions were satisfied. conclusions: of the resuscitation bags studied, those that allow the connection of an oxygen reservoir must have this reservoir connected to the bag when used as a source of oxygen in nonintubated spontaneously breathing patients. all of the models studied should receive oxygen at a rate > 15 l/min. it is not safe to use manually operated self-inflating resuscitation bags for this purpose without knowing their characteristics.

Abstract: the present study determined the impact of 1-mcp treatment on the quality maintenance of 'fuyu' persimmons, and how the postharvest exposure to ethylene could influence the 1-mcp effectiveness. the fruits were harvested at four different ripening stages according to skin color, after physiologic maturity. fruits were treated with 0.1 and 1.0 μl ·l-1 of 1-mcp one day after harvest, and then held at 23oc for up to 45 days in air with low (d" 0,1 μl ·l-1) or high (3 ± 2 μl ·l-1) ethylene . 1-mcp treatment delayed fruit softening and changes of skin color and the increase in the ethylene production, whereas it had no effect on soluble solids content and on titratable acidity. the postharvest life (period between harvest and pulp softening) of fruits was increased for up to 20 days in comparison to control fruits. persimmons harvested at advanced ripening stages had shorter postharvest life, regardless of 1-mcp treatment. the effectiveness of 1-mcp treatment was more pronounced in fruits harvested at early stages and for fruits exposed to 3 μl ·l-1 ethylene.

Abstract: this study examined the effects of ethylene action inhibitor 1-mcp (1-methylcyclopropene),ma (modified atmosphere) and ethylene oxidant kmno4 (potassium permanganate) on the quality of 'fuyu'persimmon fruit after cold storage. the factors 1-mcp, ma and kmno were combined in four manners corresponding to the following treatments: t1) control + ma + kmno4, t24) 1-mcp + ma + kmno4, t3) 1-mcp + ma, and t4) 1-mcp + aa (aa= atmosphere of air). mature-firm fruit with predominant yellow colorwere harvested from seven commercial orchards in the northeast of rio grande do sul state. some of fruit were exposed to 0.3 μl l-1 of 1-mcp for 12 h in 24 h after the harvest. after that, fruit were stored in aa or ma induced by polyethylene bags (0.04 mm thick), by 20, 40, 60 or 80 days at -0.1±0.8oc. two pellets of 8.5 g alumina-kmno4 were added into the polyethylene bags of treatments one and two before they weresealed. fruit were analyzed after 0, 3, 6 or 9 days of shelf in aa at 22±1oc. 1-mcp treatment delayed fleshsoftening, but did not consistently affect the development of skin disorders (lined dark dots and blackspots) on fruit stored in ma containing kmno4. however, the incidence of skin disorders on 1-mcp treated fruit stored in ma was significantly less than that of 1-mcp treated fruit stored in aa. there were additiveeffects of 1-mcp and ma on the retention of firmness and on the reduction of chilling injury appeared bythe formation of firm gel texture of flesh and translucent stains on the skin. the use of kmno4 did not improve the retention of fruit quality when treated with 1-mcp and stored in ma. the development of skindisorders was orchard- and storage period-dependent. however, the benefits of 1-mcp and ma combinationon the reduction of these disorders and fruit softening were consistent in all orchards. the results indicatethat 1-mcp and ma combination is an effective tool to delay the deterioration of 'fuyu' persimmon fruitduring and after cold storage.

Abstract: The Varroa destructor mite has caused the death of hundreds of thousands of Apis mellifera colonies in several countries worldwide. However, the effects determined by the Varroa mite change according to the A. mellifera subspecies. In Africanized bee colonies from South and Central America, the parasite causes little damage, as the infestation levels are relatively stable and low, thus treatments against the pest are not required. Among several factors, the grooming behavior of Africanized worker bees plays an important role in the maintenance of the low infestation levels. This study determined the daily rate of live and dead mites found at the bottom of the hive in five Africanized honey bee colonies. During fifteen days of observations, a significant increase was verified in the number of live and dead mites at the bottom of the hive as the amount of worker broods from each honey bee colony decreased. This suggests a more intense grooming activity as the Varroa concentration in the adult honey bee population increases. O ácaro Varroa destructor tem causado a mortalidade de centenas de milhares de col nias de abelhas Apis mellifera em várias partes do mundo. Os efeitos determinados pelo ácaro Varroa variam com a subespécie de Apis mellifera. Nas Américas do Sul e Central, o parasita causa poucos danos às col nias de abelhas africanizadas, a taxa de infesta o é estável e baixa, n o sendo necessário o tratamento químico contra a praga. Entre vários fatores que s o responsáveis pela tolerancia das abelhas africanizadas a esse parasita, o comportamento de grooming executado pelas operárias deve exercer importante papel na manuten o dos baixos níveis deinfesta o. Neste estudo, foram avaliadas as taxas diárias de ácaros vivos e mortos encontrados no fundo das colméias de cinco col nias de abelhas africanizadas. Durante 15 dias de observa es, foi verificado significativo aumento de ácaros no fundo da colméia à medida que diminui a quantidade de crias de operárias das col nias de abelhas. Isso sugere que a atividade de grooming é incrementada à medida que aumenta a concentra o de ácaros na popula o de abelhas adultas.
