Los “gobiernos progresista” de América Latina. La avanzada del pos-neoliberalismo

Los gobiernos “progresistas” con la puesta en marcha de su política económica, han mostrado la verdadera intención de su proyecto político, que no ha consistido en superar el neoliberalismo y mucho menos el capitalismo; y si bien se han desarrollado políticas sociales que “beneficiaron” a algunos sectores poblacionales empobrecidos, no se puede hablar de un proyecto de transformación social, sino que por el contrario, son proyectos que están afirmando la economía mercantil capitalista, en base a la más pura política gubernamental neoliberal.

Cultura organizacional en clave (pos)modernista

Esta investigación, esencialmente teórica, reflexiona sobre la deconstrucción del discurso funcionalista de la cultura organizacional, a partir de los estudios críticos en la gestión y de las teorías organizacionales posmodernistas que se sitúan en los márgenes del centro hegemónico en la administración. En un contexto dialéctico entre modernidad y posmodernidad, y sobre la base de las categorías de deconstrucción, discurso y subjetividad –que sustentan la mirada de que la realidad se constituye por medio del lenguaje– se elucida el concepto de la dimensión simbólica del “espacio-dinámica organizacional”. Además, por medio del análisis de las formaciones discursivas sobre cultura organizacional, la investigación examina las metanarrativas y los conceptos positivistas de las teorías modernistas en la gestión, en contraste con las teorías posmodernistas que visibilizan las subjetividades, que según este estudio son parte de las presunciones básicas de la cultura organizacional. La fundamentación de la estrategia metodológica forma parte de la reflexión teórica de la tesis, con la cual fue posible identificar una epistemología afín al posmodernismo organizacional como una contribución a la replicabilidad científica. Los datos empíricos –que ilustran la comprensión de los planteamientos ontológicos– fueron recogidos por medio de una etnografía enfocada, como estrategia metodológica antitética al concepto funcionalista de comprobación empírica, y se llevó a cabo en una organización cultural en la ciudad de París: el Musée du Quai Branly. La tesis contempla un aporte autorreflexivo del investigador, como leit motiv de este estudio, cuyo eje gira en torno a la comprensión de las teorías organizacionales críticas y posmodernistas.

Status and distribution of the Grey-headed Fish-Eagle (Ichthyophaga ichthyaetus) in the Prek Toal Core Area of Tonle Sap Lake, Cambodia

The regional population of the Grey-headed Fish-Eagle (Ichthyophaga ichthyaetus) in Southeast Asia is thought to be in recent decline and its conservation status Linder threat. We undertook a systematic survey in a flooded swamp forest at the Tonle Sap Lake in Cambodia and recorded 32 pairs of eagles in an area of approximately 80 km(2). Three species of water snakes were identified as eagle prey items, previously unrecorded for this species. We suggest that this eagle population has significant regional importance and discuss potential anthropogenic threats to population stability, such as water snake harvesting and construction Of upstream hydropower dams.

Determination by MAD-DM of the structure of the DNA duplex d[ACGTACG(5-BrU)]2 at 1.46 Å and 100 K

A four-wavelength MAD experiment on a new brominated octanucleotide is reported here. d[ACGTACG(5-BrU)], C77H81BrN30O32P7, (DNA) = 2235, tetragonal, P43212 (No. 96), a = 43.597, c = 26.268 Å, V = 49927.5 Å3, Z = 8, T = 100 K, R = 10.91% for 4312 reflections between 15.0 and 1.46 Å resolution. The self-complementary brominated octanucleotide d[ACGTACG(5-BrU)]2 has been crystallized and data measured to 1.45 Å at both 293 K and a second crystal flash frozen at 100 K. The latter data collection was carried out to the same resolution at the four wavelengths 0.9344, 0.9216, 0.9208 and 0.9003 Å, around the Br K edge at 0.92 Å and the structure determined from a map derived from a MAD data analysis using pseudo-MIR methodology, as implemented in the program MLPHARE. This is one of the first successful MAD phasing experiments carried out at Sincrotrone Elettra in Trieste, Italy. The structure was refined using the data measured at 0.9003 Å, anisotropic temperature factors and the restrained least-squares refinement implemented in the program SHELX96, and the helical parameters are compared with those previously determined for the isomorphous d(ACGTACGT)2 analogue. The asymmetric unit consists of a single strand of octamer with 96 water molecules. No countercations were located. The A-DNA helix geometry obtained has been analysed using the CURVES program.

Response of black oats (Avena strigosa Schreb) on the aspersion irrigation and nitrogen fertilization

The objective of the study was assessing the effect of the nitrogen and the aspersion irrigation on the growth and dry matter yield of black oats (Avena strigosa Schreb). The experiment was conducted in the Campus of USP in Pirassununga, Sao Paulo State. In the study were evaluated four nitrogen levels (0, 50, 100 and 150 kg of N ha(-1)) and also the presence or absence of the irrigation. The plant variables evaluated were: mean height, dry matter percentage, yield and growth rate. The results had disclosed to greater height of plant in the irrigated condition, reflecting in the higher production of dry matter. In dry land area, percentage of DM was 24.7% and in irrigated area 18.7%. The nitrogen was significantly only for plant mean height that showed linear fit when carried through the irrigation. The effect of the irrigation was better for the production of black oats than nitrogen.

Task assignment optimization in SAP Extended WarehouseManagement

Nowadays in the world of mass consumption there is big demand for distributioncenters of bigger size. Managing such a center is a very complex and difficult taskregarding to the different processes and factors in a usual warehouse when we want tominimize the labor costs. Most of the workers’ working time is spent with travelingbetween source and destination points which cause deadheading. Even if a worker knowsthe structure of a warehouse well and because of that he or she can find the shortest pathbetween two points, it is still not guaranteed that there won’t be long traveling timebetween the locations of two consecutive tasks. We need optimal assignments betweentasks and workers.In the scientific literature Generalized Assignment Problem (GAP) is a wellknownproblem which deals with the assignment of m workers to n tasks consideringseveral constraints. The primary purpose of my thesis project was to choose a heuristics(genetic algorithm, tabu search or ant colony optimization) to be implemented into SAPExtended Warehouse Management (SAP EWM) by with task assignment will be moreeffective between tasks and resources.After system analysis I had to realize that due different constraints and businessdemands only 1:1 assingments are allowed in SAP EWM. Because of that I had to use adifferent and simpler approach – instead of the introduced heuristics – which could gainbetter assignments during the test phase in several cases. In the thesis I described indetails what ware the most important questions and problems which emerged during theplanning of my optimized assignment method.
