Difusión de ámbitos privilegiados de acumulación en la historia argentina reciente. Intervención económica estatal y comportamiento empresario, 1966-1989

Una mirada atenta sobre la historia argentina reciente muestra con claridad la conjunción de tres fenómenos relacionados: la persistente dificultad para construir un patrón de desarrollo sostenido, el progresivo deterioro de las capacidades y de los niveles de autonomía relativa del Estado y, finalmente, la consolidación de un reducido grupo de grandes empresas. A partir de esta observación, se propone analizar la articulación entre intervención estatal, comportamiento empresario y difusión de ámbitos privilegiados de acumulación, y establecer las consecuencias que la misma generó sobre el perfil y desempeño de las diversas fracciones que componen la cúpula empresaria, entre 1966 y 1989. Dos hipótesis orientan la indagación: 1) la intervención económica estatal y las prácticas empresarias favorecieron la difusión de diversos ámbitos privilegiados de acumulación, y 2) la difusión de los ámbitos permitió la consolidación de una fracción empresaria estrechamente vinculada al funcionamiento del complejo económico estatal-privado.

Design and optimisation of a large-area process-based model for annual crops

The formulation of a new process-based crop model, the general large-area model (GLAM) for annual crops is presented. The model has been designed to operate on spatial scales commensurate with those of global and regional climate models. It aims to simulate the impact of climate on crop yield. Procedures for model parameter determination and optimisation are described, and demonstrated for the prediction of groundnut (i.e. peanut; Arachis hypogaea L.) yields across India for the period 1966-1989. Optimal parameters (e.g. extinction coefficient, transpiration efficiency, rate of change of harvest index) were stable over space and time, provided the estimate of the yield technology trend was based on the full 24-year period. The model has two location-specific parameters, the planting date, and the yield gap parameter. The latter varies spatially and is determined by calibration. The optimal value varies slightly when different input data are used. The model was tested using a historical data set on a 2.5degrees x 2.5degrees grid to simulate yields. Three sites are examined in detail-grid cells from Gujarat in the west, Andhra Pradesh towards the south, and Uttar Pradesh in the north. Agreement between observed and modelled yield was variable, with correlation coefficients of 0.74, 0.42 and 0, respectively. Skill was highest where the climate signal was greatest, and correlations were comparable to or greater than correlations with seasonal mean rainfall. Yields from all 35 cells were aggregated to simulate all-India yield. The correlation coefficient between observed and simulated yields was 0.76, and the root mean square error was 8.4% of the mean yield. The model can be easily extended to any annual crop for the investigation of the impacts of climate variability (or change) on crop yield over large areas. (C) 2004 Elsevier B.V.

Quantification of physical and biological uncertainty in the simulation of the yield of a tropical crop using present-day and doubled CO2 climates

The impacts of climate change on crop productivity are often assessed using simulations from a numerical climate model as an input to a crop simulation model. The precision of these predictions reflects the uncertainty in both models. We examined how uncertainty in a climate (HadAM3) and crop General Large-Area Model (GLAM) for annual crops model affects the mean and standard deviation of crop yield simulations in present and doubled carbon dioxide (CO2) climates by perturbation of parameters in each model. The climate sensitivity parameter (lambda, the equilibrium response of global mean surface temperature to doubled CO2) was used to define the control climate. Observed 1966-1989 mean yields of groundnut (Arachis hypogaea L.) in India were simulated well by the crop model using the control climate and climates with values of lambda near the control value. The simulations were used to measure the contribution to uncertainty of key crop and climate model parameters. The standard deviation of yield was more affected by perturbation of climate parameters than crop model parameters in both the present-day and doubled CO2 climates. Climate uncertainty was higher in the doubled CO2 climate than in the present-day climate. Crop transpiration efficiency was key to crop model uncertainty in both present-day and doubled CO2 climates. The response of crop development to mean temperature contributed little uncertainty in the present-day simulations but was among the largest contributors under doubled CO2. The ensemble methods used here to quantify physical and biological uncertainty offer a method to improve model estimates of the impacts of climate change.

Niagara Regional Historical Council fonds, 1960-1989

The Lincoln County Historical Council began meeting December 17,1960 under the advisement of the Publicity, Planning and Development Committee of Lincoln County. The group was composed of three members appointed from each of the four existing historical societies: one member appointed from the executive of the Women’s Institute, one member from Lincoln County Council, the Deputy-Clerk and Treasurer of the County and a member from the Niagara Editorial Bureau. The Welland County Historical Council was soon formed after this along the same lines. In the early 1960’s the Lincoln and Welland County historical councils began work on an inventory of historic buildings with the intent to emphasize the historical significance of this area. The information gathered by volunteers and a professional photographer and an architect was used to present a “brief” to the federal government in 1962 and the provincial government in 1963. This brief, An Area of Historical Interest in the Counties of Lincoln and Welland, Ontario was published in 1962 and revised and distributed to schools and libraries in the area in 1965. The Ontario Buildings Inventory Project became a provincial initiative spearheaded by the Department of Public Records and Archives, a branch of the Department of Tourism and Information, ca. 1966. Volunteers collected and photographed buildings of historical interest in Lincoln and Welland counties. This information was recorded on standardized survey forms for every township in the Niagara region. Niagara Regional Historical Council was created with the merger of Lincoln County Historical Council and Welland County Historical Council, at the time of the formation of Niagara Regional Government in 1970. The first meeting of the new council was held January 1970.

Historical and Personal Perspectives on the Fall of the Berlin Wall, 1989: address to 20th anniversary forums.

The story of the fall of the Berlin Wall was an aspect of the “imagination gap” that we had to wrestle with as journalists covering the collapse of the Eastern Bloc in Europe. It was scarcely possible to believe what you found yourself reporting, and that work became a two-track process. On one hand a mass social movement was dictating the pace and direction of events; on the other, the institutional business of politics as usual, to provide a framework for all the change that was happening, had to be managed – and reported on. In later analyseds we could see, that crisis in the Soviet Union led to the crisis over the Berlin Wall; and from the fall of the Wall, came Germany’s reunification, and with that also, formation of the European Union as it is today. The government of the Federal Republic of Germany convinced its neighbours that a reunited Germany, within an expanded EU, would be a very acceptable “European Germany” -- not the leader of a “German Europe”. It committed itself financially, supporting the new Euro currency. The former communist states of Eastern Europe demanded to join and expand the EU; in order to remove themselves from the Soviet Union, enjoy human rights, and share in Western prosperity. So today, following on from the events of 1989, the European Union is an amalgam of 27 member countries, with close to 500 million citizens and accounting for 30 % of world Gross National Product.

Prevalence of Staphylococcus aureus strains in an Australian cohort, 1989-2003 : evidence for the low prevalence of the toxic shock toxin and Panton-Valentine leukocidin genes

The purpose of this paper is to determine the prevalence of the toxic shock toxin gene (tst) and to enumerate the circulating strains of methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA) in Australian isolates collected over two decades. The aim was to subtype these strains using the binary genes pvl, cna, sdrE, pUB110 and pT181. Isolates were assayed using real-time polymerase chain reaction (PCR) for mecA, nuc, 16 S rRNA, eight single-nucleotide polymorphisms (SNPs) and for five binary genes. Two realtime PCR assays were developed for tst. The 90 MRSA isolates belonged to CC239 (39 in 1989, 38 in 1996 and ten in 2003), CC1 (two in 2003) and CC22 (one in 2003). The majority of the 210 MSSA isolates belonged to CC1 (26), CC5 (24) and CC78 (23). Only 18 isolates were tst-positive and only 15 were pvl-positive. Nine MSSA isolates belonged to five binary types of ST93, including two pvlpositive types. The proportion of tst-positive and pvl-positive isolates was low and no significant increase was demonstrated. Dominant MSSA clonal complexes were similar to those seen elsewhere, with the exception of CC78. CC239 MRSA (AUS-2/3) was the predominant MRSA but decreased significantly in prevalence, while CC22 (EMRSA-15) and CC1 (WA-1) emerged. Genetically diverse ST93 MSSA predated the emergence of ST93- MRSA (the Queensland clone).

Designing relational pedagogies with jam2jamXO

This paper examines the affordances of the philosophy and practice of open source and the application of it in developing music education software. In particular I will examine the parallels inherent in the ‘openness’ of pragmatist philosophy in education (Dewey 1916, 1989) such as group or collaborative learning, discovery learning (Bruner 1966) and learning through creative activity with computers (Papert 1980, 1994). Primarily I am interested in ‘relational pedagogies’ (Ruthmann and Dillon In Press) which is in a real sense about the ethics of the transaction between student and teacher in an ecology where technology plays a more significant role. In these contexts relational pedagogies refers to how the music teacher manages their relationships with students and evaluates the affordances of open source technology in that process. It is concerned directly with how the relationship between student and teacher is affected by the technological tools, as is the capacity for music making and learning. In particular technologies that have agency present the opportunity for a partnership between user and technology that enhances the capacity for expressive music making, productive social interaction and learning. In this instance technologies with agency are defined as ones that enhance the capacity to be expressive and perform tasks with virtuosity and complexity where the technology translates simple commands and gestures into complex outcomes. The technology enacts a partnership with the user that becomes both a cognitive and performative amplifier. Specifically we have used this term to describe interactions with generative technologies that use procedural invention as a creative technique to produce music and visual media.
