The Ricardian vice and the indetermination of senior

The general commitments and working requirements of abstract, applied, and art of science, including economics, are assessed. Pure economics deals with the logic of the phenomenon. Positive socio-economics presupposes pure economics and many distinct sciences. Art presupposes socio-economics and direct knowledge of the specificities which characterize the time-space individuality of the phenomenon. This indetermination was partially formulated by Senior and Mill; graduate education in economics is considered in its light. The habit of ignoring it is the Ricardian Vice, as named by Schumpeter; the prevalence of the vice is exemplified, and its causes analyzed.

The indetermination of senior (or the indetermination of Wagner) and Schmoller as a Social Economist

The propositions of pure economics, whatever be their generality and their truth, do not authorize normative concluaions, but cannot be ignored. The latter, namely what ought not to be done, is derivable from socio-economics. The derivation is to be qualified by the specificities of the case. I have called this the Indetermination of Senior; Wagner and Marshall were quite aware of it. The habit of ignoring it is the Ricardian Vice; Schmoller's fight may have been a reaction against the latter. The Methodenstreit was the first great paradigmatic conflict between pure and social economists.

A indeterminação de senior e o curriculo minimo de economia

Expõe-se um programa de pesquisa sobre a natureza incompleta do conhecimento científico, estendendo-o para análise do currículo mínimo de economia no Brasil, e a consequente formulação de propostas de mudança. Considerando os diferentes níveis de abstração na tricotomia ciência pura, aplicada e arte da ciência, observa-se que o currículo mínimo prescreve formação apropriada para a economia social ou aplicada. Conclui-se pela conveniência de mais dois anos, um para reforço da economia pura no ciclo básico, outro para a arte da economia no profissionalizante. Considera-se ainda uma especialização em economia pura, voltada apenas para ensino e pesquisa.

Female senior managers in the Brazilian finance industry: a journey towards success

No nível global, a representação de líderes de sexo feminino nas empresas muitas vezes ainda se dá em números baixos em termos de percentagem. Particularmente em finanças, esses registros estão abaixo da média da indústria, e a forte concorrência e o ambiente de trabalho dominado pelos homens tornam difícil para as mulheres atingir o topo da pirâmide corporativa (Torres et al., 2013; OECD Better Life Index 2015). Isto pode ser devido a uma falta de equilíbrio trabalho-vida, diferentes estilos de liderança, as mulheres sendo intimidadas, ou a conformidade com estruturas familiares convencionalmente englobadas. No Brasil, os códigos de comportamento tradicionais são muito palpáveis na sociedade do país, embora esta também tenha se beneficiado de uma forte presença de movimentos feministas na segunda metade do século passado (Tate and Yang, 2015; Bowles et al. 2007; Niederle and Vesterlund, 2007). Nos últimos anos, o setor financeiro brasileiro tem crescido, oferecendo maiores oportunidades de emprego e desenvolvimento de carreira nas corporações nacionais e internacionais (Chiang et al., 2013; Bruschini, 2007). Esta dissertação aborda os desafios enfrentados por líderes de sexo feminino do mercado financeiro brasileiro e as suas trajetórias de carreira. Este objetivo será atingido por meio de uma análise de mídia social, focando nos anos de experiência de trabalho das mulheres analisadas, a posição atual delas e se elas têm filhos, bem como com 10 entrevistas semiestruturadas realizadas com executivas no setor financeiro no Brasil. Estas medidas irão abranger lacunas na literatura e consequentes recomendações para pesquisas futuras.

Cellulose pyrolysis and quantum chemistry

Cellulose is the major constituent of most plants of interest as renewable sources of energy and is the most extensively studied form of biomass or biomass constituent. Predicting the mass loss and product yields when cellulose is subjected to increased temperature represents a fundamental problem in the thermal release of biomass energy. Unfortunately, at this time, there is no internally consistent model of cellulose pyrolysis that can organize the varied experimental data now available or provide a guide for additional experiments. Here, we present a model of direct cellulose pyrolysis using a multistage decay scheme that we first presented in the IJQC in 1984. This decay scheme can, with the help of an inverse method of assigning reaction rates, provide a reasonable account of the direct fast pyrolysis yield measurements. The model is suggestive of dissociation states of d-glucose (C6H10O5,), the fundamental cellulose monomer. The model raises the question as to whether quantum chemistry could now provide the dissociation energies for the principal breakup modes of glucose into C-1, C-2, C-3, C-4, and C-5 compounds. These calculations would help in achieving a more fundamental description of volatile generation from cellulose pyrolysis and could serve as a guide for treating hemicellulose and lignin, the other major biomass constituents. Such advances could lead to the development of a predictive science of biomass pyrolysis that would facilitate the design of liquifiers and gasifiers based upon renewable feedstocks.

Influence of thermal annealing treatment in oxygen atmosphere on grain boundary chemistry and non-ohmic properties of SnO2 center dot MnO polycrystalline semiconductors

The present work studied the influence of thermal treatment in oxygen rich atmosphere on heterogenous junctions in Mn-doped SnO2 polycrystalline system presenting varistor behavior. The samples were prepared by conventional oxide mixture methodology, and were submitted to heat treatment in oxygen rich atmosphere at 900 degrees C for 2h. The samples were characterized by X-ray diffraction, scanning electron microscopy, dc and ac electrical measurements. The results showed that there is an evident relationship between the microstructure heterogeneity and non-ohmic electrical properties. It was found that for this SnO2 center dot MnO-based varistor system the heat treatment in oxygen rich atmosphere does not necessarily increase the varistors properties, which was related to the decrease in the grain boundary resistance. The results are compared with Co-doped SnO2 varistors and ZnO based varistors. (C) 2008 WILEY-VCH Verlay GmbH & Co. KGaA, Weinheim.

Snake venom phospholipase A(2) inhibitors: Medicinal chemistry and therapeutic potential

Phospholipases A(2) (PLA(2)s) are commonly found in snake venoms from Viperidae, Hydrophidae and Elaphidae families and have been extensively studied due to their pharmacological and physiopathological effects in living organisms. This article reports a review on natural and artificial inhibitors of enzymatic, toxic and pharmacological effects induced by snake venom PLA(2)s. These inhibitors act on PLA(2)S through different mechanisms, most of them still not completely understood, including binding to specific domains, denaturation, modification of specific amino acid residues and others. Several substances have been evaluated regarding their effects against snake venoms and isolated toxins, including plant extracts and compounds from marine animals, mammals and snakes serum plasma, in addition to poly or monoclonal antibodies and several synthetic molecules. Research involving these inhibitors may be useful to understand the mechanism of action of PLA(2)s and their role in envenomations caused by snake bite. Furthermore, the biotechnological potential of PLA(2) inhibitors may provide therapeutic molecular models with antiophidian activity to supplement the conventional serum therapy against these multifunctional enzymes.
