A nova lei de patentes, a indústria química e a universidade

This paper aims to present some features of the Industrial Property Law now in force in Brazil, as far as they could be regarded to the activities of research and development in the field of Chemistry and related areas, not only in the chemical industry but also in the university. By means of analysis of the main articles and paragraphs, which could deal with the mentioned activities, the author points out the scope and limitations of that law and explains the meaning of common technical terms usually found in patent concerns. Ultimately, a brief discussion on the actual and the potential role of the Brazilian university in the sphere of the Industrial Property is made.

Propagação da poluição atmosférica por flúor nas águas subterrâneas e solos de regiões próximas às indústrias de fertilizantes (Rio Grande, RS)

Fluoride concentration was determined in rainwater, ground water and soil in the zone of fertilizer industry in the city of Rio Grande. In contaminated rainwater fluorine concentration was registered up to the value of 4,4 mg.L-1. Fluorine concentration in the shallow ground water in general reflects its distribution in the atmosphere, but cannot be used as marker of atmosphere contamination in the urban area due to dissolving influence of residential effluents. The 0,01% HCl extracts from the set of surface soil samples demonstrates fluoride distribution in the zone of influence of industrial emissions, which coincides to the numerical simulation of fluorides dispersion in the air.

ARSÊNIO E ARROZ: TOXICIDADE, METABOLISMO E SEGURANÇA ALIMENTAR

Arsenic is considered a semimetal, and its wide distribution in the Earth's crust in different chemical forms, including organic and inorganic species, has a great deal of influence on the mechanisms of toxicity. Exposure to arsenic can be either through occupational practice (use of pesticides) or by the consumption of water and food containing the element. Rice is considered a fundamental constituent of the basic diet of Brazilians and is usually cultivated in flooded conditions. Such a plantation system results in an increased amount of As in the soil and hence a greater accumulation of As in the plant, which is highlighted by the inorganic species' classification as highly toxic. Besides the use of mitigation techniques to reduce the toxicological risk, monitoring the concentration of As and its chemical species in rice and rice products is required through the establishment of legislation in the area. Thus, some world organizations are conducting improved research to determine and establish acceptable concentrations of As and its chemical species in rice, e. g., in 2012, FDA researchers described a chemical speciation methodology for As in rice and rice products. Hence, the application of existing chemical speciation methods and the establishment of parameters for ensuring food security and exposure risk assessment deserve particular consideration.

Respostas a uma crítica marxista às perspectivas retórica e pragmática em economia

Answers to a marxist critic of the rhetorical and pragmatic perspectives in economics. Based on recent discussions regarding the rhetorical perspective in economics, this paper presents an interpretation of the philosophical approach of Habermas which attempts to rescue the so called 'modern spirit', forgotten in the annals of the 19th century, similar to that presented by Marshall Berman in 1982. Following the reconstructive approach of Habermas's project of modernity, we attempt to show how a 'rhetorical approach' could be applied in the field of economics, and yet still be clearly modern by taking into account intersubjectivities, given the expanded sphere of human communication (as defended in the theory of communicative action of Habermas). In this sense, we will seek to demonstrate the philosophical limits of the anti-rhetorical critiques of, for example, Paulani (1996, 2003, 2005, 2006), which seem to underestimate the linguistic and intersubjective aspect of Habermas's philosophical project that can also be found in McCloskey’s methodological approach.

Judiciário e política regulatória: instituições e preferências sob a ótica dos custos de transação

Judiciary and regulatory policy. Increasingly, judges and the courts appear as actors capable of affecting the trajectory of the government decisions, as strategic agents in the policy process. This paper presents an analytical model able to clearly and objectively measure the impact of judicial review in the design of policies in the sphere of economic regulation. Underlying the model is the concept of transaction costs, through which one can raise the levels of intervention of the judiciary in regulatory policy. In addition to the analytical model, the article demonstrates that the interaction between the heterogeneity of preferences in the courts and institutional mechanisms of the justice system is capable of generating greater coordination and cooperation than expected.

From transcendental to practical intersubjectivity: a social psychological approach to Kant's musical aesthetics

It is well known that Kant’s aesthetics is framed intersubjectively because he upholds the claim of taste to universality. However, the transcendental foundation of this shared universality is a supersensible ground which is taken for granted but which cannot be brought directly into communicative experience. Kant’s reliance on the synthetic a priori structure of aesthetic judgment also removes it from the sphere of observable personal interaction. This argumentative strategy exposes it to skeptical challenge and generates inaccessible references to inner representations (be they intuitions, categories of the understanding or rational ideas). It is not sufficient, as Kant did, to propose a description of aesthetic experience that is subjectively plausible and thereby claim its intersubjective validity. It is indispensable to embody intersubjectivity in behavior and language. In practical intersubjectivity, aesthetic attitudes are dealt with in a concrete and accessible manner without relying on mentalistic assumptions as a foundation. Conceptual terms such as 'agreeable’, 'beauty’, 'sublime’, 'ugly’, 'universality’ acquire new meaning in a conversational context and aesthetic claims are tested in a dialogical game semantics model.
