A controvérsia sobre a lei de tendência decrescente da taxa de lucro

Tendo em vista a controvérsia a respeito da lei de tendência decrescente da taxa de lucro formulada por Karl Marx, este artigo pretende discutir duas correntes principais que se contrapõem na interpretação da referida lei. Uma, que defende a reformulação e atualização das leis marxistas de acumulação e, outra que defende sua atualidade. Além disso, pretende também levantar alguns pontos polêmicos na interpretação da lei de tendência relacionada com as crises do capitalismo.

Lei e ordem econômica no pensamento de John R. Commons

The paper has analyzed John R. Commons' contribution to the comprehension of Law and Economics relationship. In contrast to the orthodox economics, Commons has shown that the capitalist economic order emerges and functions regulated by laws and institutions. These approaches made possible to him to understand the nature of the modern capitalist wealth and the problems that time introduces in economic transactions.

A lei seca cumpriu sua meta em reduzir acidentes relacionados à ingestão excessiva de álcool?

OBJECTIVE: To assess whether the Brazilian Driving Dry Law reached its goal after the three years following its enactment. METHODS: We onnducted a retrospective study of patients with craniofacial fractures who underwent surgery at a university hospital in two periods: before the Law (2005 to 2008) and after the Law (2008 to 2011). RESULTS: 265 patients (220 men and 45 women) were operated on during this period, 149 (56%) before and 116 (44%) after the Law, which indicates a reduction in the number of traumatisms (p=0.04). The age range between 19 and 40 years predominated in both periods. The main causes of traumas were car accidents, physical aggression and falls. Alcohol abuse was identified in 15.4% patients before and 19% patients after the enactment. The jaw and the maxillo-zygomatic complex were the most affected bones. CONCLUSION: The drop in the number of polytraumatized patients operated on at this institution in the three years following the Driving Dry Law was 22%, which is below the expected and desired percentage. These results must be compared to those of different services offering the same attendance type in order to compile data and enlarge statistics. The low index of reduction in the number of traumatisms and the report of alcohol abuse by several patients at the moment of trauma, even after the law, evidence the need of adopting stricter measures to control and punish violators.

Measurement of the ZZ production cross section and search for anomalous couplings in 2l2l' final states in pp collisions at root s=7 TeV

A measurement is presented of the ZZ production cross section in the ZZ -> 2l2l' decay mode with l = e, mu and l' = e, mu, tau in proton-proton collisions at root s = 7 TeV with the CMS experiment at the LHC. Results are based on data corresponding to an integrated luminosity of 5.0 fb(-1). The measured cross section sigma(pp -> ZZ) = 6.24(-080)(+0.86) (stat.)(-0.32)(+0.41) (syst.) +/- 0.14 (lumi.) pb is consistent with the standard model predictions. The following limits on ZZZ and ZZ-gamma anomalous trilinear gauge couplings are set at 95% confidence level: -0.011 < f(4)(Z) < 0.012, -0.012 < f(5)(Z) < 0.012, -0.013 < f(4)(gamma) < 0.015, and -0.014 < f(5)(gamma) < 0.014.
