Argentina’s quarter century experiment with neoliberalism: from dictatorship to depression

Em 2002, a Argentina atingiu um novo marco histórico, ao experimentar o maior default da dívida externa, não somente pela sua própria história, mas também do mundo. Para compreender como a Argentina deixou de ser um país mais desenvolvido de terceiro mundo até experimentar a crise de 2001, entrando depois numa depressão em 2002, com mais da metade da população abaixo da linha de pobreza, precisamos fazer uma avaliação das políticas econômicas durante o último quarto de século na Argentina. A virada ao neoliberalismo começou durante a ditadura no ano 1976, tendo se aprofundado no governo Menem e sempre apoiada pelo FMI. Este trabalho tentará identificar porque a crise ocorreu naquele momento, e também, compreender as mudanças subjacentes na economia política durante duas décadas na Argentina, as quais que desencadearam duas ondas de desindustrialização, uma explosão da dívida externa e uma deterioração bem marcante no padrão de vida para a maioria dos argentinos.

Improved sperm cryosurvival in diluents containing amides versus glycerol in the Przewalski's horse (Equus ferus przewalskii)

Two studies were conducted to understand sperm cryosensitivity in an endangered equid, the Przewalski's horse (Equus ferns przewalski), while testing the cryoprotectant ability of formamides. The first assessed the toxicity of permeating cryoprotectants (glycerol, methylformamide IMF] and dimethylformamide [DMF]) to Przewalski's horse spermatozoa during liquid storage at 4 C. The second examined the comparative influence of three diluents (with or without formamides) on cryosurvival of sperm from the Przewalski's versus domestic horse. When Przewalski's horse spermatozoa were incubated at 4 C in INRA 96 with differing concentrations of glycerol, MF or DMF or a combination of these amides, cells tolerated all but the highest concentration (10% v/v) of MF alone or in combination with DMF, both of which decreased (P < 0.05) motility traits. There was no effect of cryoprotectants on sperm acrosomal integrity. In the cryosurvival study, average sperm motility and proportion of cells with intact acrosomes in fresh ejaculates were similar (P> 0.05) between the Przewalski's (67%, 84%, respectively) and domestic (66%, 76%) horse donors. Sperm from both species were diluted in lactose-EDTA-glycerol (EQ), Botu-Crio (BOTU; a proprietary product containing glycerol and MF) or SM (INRA 96 plus 2% [v/v] egg yolk and 2.5% [v/v] MF and DMF) and then frozen over liquid nitrogen vapor. After thawing, the highest values recovered for total and progressive sperm motility, acrosomal integrity and mitochondria] membrane potential were 42.4%, 21.8%, 88.7% and 25.4 CN (CN = mean JC-1 fluorescence intensity/cell on a channel number scale), respectively, in the Przewalski's and 49.3%, 24.6%, 88.9% and 25.8 CN, respectively, in the domestic horse. Although sperm progressive motility and acrosome integrity did not differ (P> 0.05) among treatments across species, mitochondrial membrane potential was higher (P< 0.05) in both species using EQ compared to BOTU or SM media. Additionally, Przewalski's stallion sperm expressed higher (P < 0.05) post-thaw total motility in BOTU and SM compared to EQ whereas there were no differences among freezing diluents in the domestic horse. In summary, Przewalski's stallion sperm benefit from exposure to either MF or DMF as an alternative cryoprotectant to glycerol. Overt sperm quality appears similar between the Przewalski's and domestic horse, although the total motility of cells from the former appears more sensitive to certain freezing diluents. Nonetheless, post-thaw motility and acrosomal integrity values for Przewalski's horse spermatozoa mimic findings in the domestic horse in the presence of INRA 96 supplemented with 2% (v/v) egg yolk and a combined 2.5% concentration of MF and DMF.

Transparencia presupuestaria en los gobiernos municipales de Brasil por medio de internet: el caso de Piracicaba São Paulo

This article seeks to assess the extent to which the municipality of Piracicaba (in the Brazilian state of São Paulo) has practiced Municipal Budgetary Transparency in Internet (TOM Web), as conceptualized by Pires (2011). The TOM Web is based on definitions used by the IMF and the OECD, and the characteristics of the Brazilian institutional and legal reality.

O engavetamento de modelos de ensino superior dentro da universidade pública

This paper explores the contradictions between models conflicting today in Brazilian universities. The conglomeration of isolated institutions, integrated and multifunctional university and university-enterprise, service provider. This last model attempts to integrate higher education institutions to supply chains dominated by capital. Public universities were designed to provide innovative services and train staff researchers for such activity. The training of skilled workforce would be fundamentally task of private universities. But in any case, the onus would be on this training students. This model has been driven from the 1990s, with "instruction manuals" of the World Bank, and in 2000, with the IMF recommendations and, in the case of Latin American universities, Fundación Universia, sponsored by the Santander Bank. The question remains: the university will be able to organize the productive forces which have around research goals and staff training for independent development.

High-throughput non-destructive nuclear magnetic resonance method to measure intramuscular fat content in beef

High intake of saturated fat from meats has been associated with cardiovascular disease, cancer, diabetes, and others diseases. In this paper, we are introducing a simple, high-throughput, and non-destructive low-resolution nuclear magnetic resonance method that has the potential to analyze the intramuscular fat content (IMF) in more than 1,000 beef portions per hour. The results can be used in nutritional fact labels, replacing the currently used average value. The method is based on longitudinal (T(1)) and transverse (T(2)) relaxation time information obtained by a continuous wave-free precession (CWFP) sequence. CWFP yields a higher correlation coefficient (r=0.9) than the conventional Carr-Purcell-Meiboom- Gill (CPMG) method (r=-0.25) for IMF in beef and is just as fast and a simpler pulse sequence than CPMG. The method can also be applied to other meat products.

Sulfur isotope analysis of aerosol particles by NanoSIMS

A new method to measure the sulfur isotopic composition of individual aerosol particles by NanoSIMS has been developed and tested on several standards such as barite (BaSO4), anhydrite (CaSO4), gypsum (CaSO4·2H2O), mascagnite ((NH4)2SO4), epsomite (MgSO4·7H2O), magnesium sulfate (MgSO4·xH2O), thenardite (Na2SO4), boetite (K2SO4) and cysteine (an amino acid). This ion microprobe technique employs a Cs+ primary ion beam and measures negative secondary ions permitting the analysis of sulfur isotope ratios in individual aerosol particles down to 500 nm in size (0.001-0.5 ng of sample material). The grain-to-grain reproducibility of measurements is typically 5‰ (1σ) for micron-sized grains, <5‰ for submicron-sized grains, and <2‰ for polished thin sections and ultra microtome sections which were studied for comparison. The role of chemical omposition (matrix effect) and sample preparation techniques on the instrumental mass fractionation (IMF) of the 34S/32S ratio in the NanoSIMS has been investigated. The IMF varies by ~15‰ between the standards studied here. A good correlation between IMF and ionic radius of the cations in sulfates was observed. This permits to infer IMF corrections even for sulfates for which no isotope standards are available. The new technique allows to identify different types of primary and secondary sulfates based on their chemical composition and to measure their isotopic signature separately. It was applied to marine aerosol samples collected in Mace Head and urban aerosol samples collected in Mainz. It was shown that primary sulfate particles such as sulfate in NaCl or gypsum particles precipitated from ocean water retain the original isotopic signature of their source. The isotopic composition of secondary sulfate depends on the isotopic composition of precursor SO2 and the oxidation pathway. The 34S/32S fractionation with respect to the precursor SO2 is -9‰ for homogeneous oxidation and +16.5‰ for heterogeneous oxidation. This large difference between the isotopic fractionation of both pathways allows identifying the oxidation pathway from which the SO42- in a secondary sulfate particle is derived, by means of its sulfur isotope ratio, provided that the isotopic signature of the precursor SO2 is known. The isotopic composition of the precursor SO2 of secondary sulfates was calculated based on the isotopic composition of particles with known oxidation pathway such as fine mode ammonium sulfate.

Demokratie, good governance und Entwicklung: Eine quantitative Analyse für 191 Staaten im Zeitraum 1996 bis 2005

Das Jahr 1989 markiert nicht nur den Beginn entscheidender geopolitischer Veränderungen, sondern gleichzeitig den Ursprung eines bedeutsamen Wandels in der internationalen Entwicklungszusammenarbeit. Mit der viel beachteten Studie ‚Sub-Saharan Africa – From Crisis to Sustainable Growth’ initiierte die Weltbank eine Debatte über die Relevanz institutioneller Faktoren für wirtschaftliche Entwicklung, die in den folgenden Jahren unter dem Titel ‚Good Governance’ erhebliche Bedeutung erlangte. Nahezu alle zentralen Akteure begannen, entsprechende Aspekte in ihrer praktischen Arbeit zu berücksichtigen, und entwickelten eigene Konzepte zu dieser Thematik. Wenn auch mit der Konzentration auf Institutionen als Entwicklungsdeterminanten eine grundlegende Gemeinsamkeit der Ansätze festzustellen ist, unterscheiden sie sich jedoch erheblich im Hinblick auf die Einbeziehung politischer Faktoren, so dass von einem einheitlichen Verständnis von ‚Good Governance’ nicht gesprochen werden kann. Während die meisten bilateralen Akteure sowie DAC und UNDP Demokratie und Menschenrechte explizit als zentrale Bestandteile betrachten, identifiziert die Weltbank einen Kern von Good Governance, der unabhängig von der Herrschaftsform, also sowohl in Demokratien wie auch in Autokratien, verwirklicht werden kann. Die Implikationen dieser Feststellung sind weit reichend. Zunächst erlaubt erst diese Sichtweise der Bank überhaupt, entsprechende Aspekte aufzugreifen, da ihr eine Berücksichtigung politischer Faktoren durch ihre Statuten verboten ist. Bedeutsamer ist allerdings, dass die Behauptung der Trennbarkeit von Good Governance und der Form politischer Herrschaft die Möglichkeit eröffnet, Entwicklung zu erreichen ohne eine demokratische Ordnung zu etablieren, da folglich autokratische Systeme in gleicher Weise wie Demokratien in der Lage sind, die institutionellen Voraussetzungen zu verwirklichen, welche als zentrale Determinanten für wirtschaftlichen Fortschritt identifiziert wurden. Damit entfällt nicht nur ein bedeutsamer Rechtfertigungsgrund für demokratische Herrschaft als solche, sondern rekurrierend auf bestimmte, dieser zu attestierende, entwicklungshemmende Charakteristika können Autokratien nun möglicherweise als überlegene Herrschaftsform verstanden werden, da sie durch jene nicht gekennzeichnet sind. Die Schlussfolgerungen der Weltbank unterstützen somit auch die vor allem im Zusammenhang mit der Erfolgsgeschichte der ostasiatischen Tigerstaaten vertretene Idee der Entwicklungsdiktatur, die heute mit dem Aufstieg der Volksrepublik China eine Renaissance erlebt. Der wirtschaftliche Erfolg dieser Staaten ist danach auf die überlegene Handlungsfähigkeit autokratischer Systeme zurückzuführen, während Demokratien aufgrund der Verantwortlichkeitsbeziehungen zwischen Regierenden und Regierten nicht in der Lage sind, die notwendigen Entscheidungen zu treffen und durchzusetzen. Die dargestellte Sichtweise der Weltbank ist allerdings von verschiedenen Autoren in Zweifel gezogen worden, die auch für ein im Wesentlichen auf technische Elemente beschränktes Good Governance-Konzept einen Zusammenhang mit der Form politischer Herrschaft erkennen. So wird beispielsweise vertreten, das Konzept der Bank bewege sich ausdrücklich nicht in einem systemneutralen Vakuum, sondern propagiere zumindest implizit die Etablierung demokratischer Regierungsformen. Im Übrigen steht die aus den Annahmen der Weltbank neuerlich abgeleitete Idee der Entwicklungsdiktatur in einem erheblichen Widerspruch zu der von multilateralen wie bilateralen Akteuren verstärkt verfolgten Förderung demokratischer Herrschaft als Mittel für wirtschaftliche Entwicklung sowie der fortschreitenden Verbreitung der Demokratie. Besteht nun doch ein Einfluss der Herrschaftsform auf die Verwirklichung von Good Governance als zentraler Entwicklungsdeterminante und kann zudem davon ausgegangen werden, dass Demokratien diesbezüglich Vorteile besitzen, dann ist eine Entwicklungsdiktatur keine denkbare Möglichkeit, sondern im Gegenteil demokratische Herrschaft der gebotene Weg zu wirtschaftlichem Wachstum bzw. einer Verbesserung der Lebensverhältnisse. Aufgrund der mit den Schlussfolgerungen der Weltbank verbundenen bedeutsamen Implikationen und der bisher weitestgehend fehlenden ausführlichen Thematisierung dieses Gegenstands in der Literatur ist eine detaillierte theoretische Betrachtung der Zusammenhänge zwischen den zentralen Elementen von Good Governance und demokratischer Herrschaft notwendig. Darüber hinaus sollen die angesprochenen Beziehungen auch einer empirischen Analyse unterzogen werden. Gegenstand dieser Arbeit ist deshalb die Fragestellung, ob Good Governance eine von demokratischer Herrschaft theoretisch und empirisch unabhängige Entwicklungsstrategie darstellt.
