Hostilidad diplomática y la armonía comercial: los límites de la retórica de la globalización en las relaciones comerciales entre Venezuela y Estados Unidos

En los últimos años, Venezuela ha manejado una política más retórica que efectiva, supeditada a otros intereses nacionales y de seguridad estadounidenses, tales como la lucha antidroga, la compra de petróleo, y la expansión del libre comercio. En este sentido; la presente investigación constituye un acercamiento por comprender cómo a pesar de las hostilidades diplomáticas-políticas desarrolladas por los gobiernos de Venezuela y Estados Unidos, sus relaciones comerciales siguen constituyendo un punto de encuentro entre ambos. Los objetivos propuestos en el mismo están enmarcados en analizar la política exterior de Venezuela y sus intentos por diversificar el mercado donde posiciona su preciado oro negro, que hasta los momentos ha tenido un destino fijo y seguro Estados Unidos. La dicotomía política y el desenvolvimiento de la política exterior de Venezuela durante el gobierno de Chávez en relación a su vecino del Norte, centrando en el período que corresponde a George W. Bush, constituye en centro de esta investigación.

Políticas de educação profissional técnica e de ensino médio no Brasil: a implementação no CEFET-RN (1998 2008)

This study has analyzed the high school and professional education policies (1998-2008) and their impacts on the Centro Federal de Educação Tecnológica do Rio Grande do Norte. It has presented an analysis and design of the productive restructuring process in the world of work and education, the technical, vocational education and high school policies in Brazil, referring to this period, as well as the changes in Cefet-RN for implementation of Political Guidelines of Vocational, Technical and High School Education. This study is guided by assumptions related to these policies, which are located in different historical moments. It is a study in which subjects are understood as historical and social beings, embedded in the economic, political and cultural rights which, by its actions, can be transformed. It was based on a theoretical framework consistent with the object of research to give it shape and meaning, serving as a parameter to address the problem outlined in research questions. It was used analysis of bibliographical material and specific documents from the Institution, semi-structured interviews with the subjects part of technical and high school. Results show that many of the recommendations in the present high school policies and vocational technical and high school education, implemented in Cefet-RN, for the period 1998-2002, show inconsistencies between what is said and what can be officially established in the pedagogical practice of teachers and professional practice of some graduates. Regarding the integration of vocational education with the high school (2005-2008) in this Institution, the study signaled that its prioritization failed to materialize in full, in Cefet-RN, although it was developed and implemented a Political-Pedagogical Project in 2005

Plano real e a nova realidade brasileira

This paper analyzes the Real Plan and its effects on two administrations of President Fernando Henrique Cardoso (FHC), a period which extends from 1995 to 2002. To this end, the study includes a brief review of the problems faced by previous plans, especially the Cruzado Plan and the reasons for the belief that it has been successfull in relation to inflation control. Additionally, seeking to describe the process of moving to the new currency towards stabilization, the paper describes the theoretical foundations of the Plan. In sequence, it defines the backround of both international and domestic monetary reform which was one important part of the Plan and therefore the reasons for the implementation of the monetary reform. Subsequently the paper deals with the effects of the Plan on the economy as a whole, covering also the way the economic measures were taken concerning the Mexican and Asian crisis, the policies used fot the exchange rate, interest rate, fiscal accounts, balance of payments, among other factors and the relationship between them. Hence, it describes the immediate and the long-term consequences of stabilization program in terms of output, employment, public deficit and debt. Therefore, it is important to note the various junctures to which the economy was exposed, and also to point out the challenges and obstacles arising from these changes for growth, which was sometimes fast, sometimes slowing down - the so-called stop and go. Of course, facts as the moving to floating exchange rate regime, the adoption of inflation targeting regime and the adoption of fiscal responsibility law along with the primary surplus policy were able to create a new economic environment and to contribute to later success of the Cardoso years

Privatizações no governo FHC e a evolução do transporte rodoviário no Brasil

Diante das transformações econômicas e políticas que marcaram os anos 1990 no Brasil, em especial o Governo de Fernando Henrique Cardoso, o presente estudo busca abordar os principais fatores que levaram à mudança do papel do Estado na economia, à evolução da malha rodoviária como um dos principais avanços do período, bem como às concessões de rodovias realizadas, as quais se tornaram essenciais ao desenvolvimento da infraestrutura brasileira e ao escoamento da produção nacional, inseridos no contexto das privatizações

Análisis de la participación política de la mujer indígena por circunscripción especial para Senado 1991-2014 Mecanismos, alcances y límites

Esta investigación se enfoca en la participación política al Senado de las mujeres indígenas en Colombia por circunscripción especial desde 1991 a 2014. A partir de una contextualización que permite ubicar el papel de las mujeres dentro del movimiento indígena, presenta los mecanismos adoptados por la Constitución de 1991, de la Ley de Cuotas y de la Ley de Partidos, para asegurar una presencia indígena en el Senado y garantizar una participación política paritaria. Posteriormente, muestra y analiza, con base en resultados electorales y en testimonios de lideresas indígenas, que dichos instrumentos han quedado ineficientes para hacer posible la elección de mujeres indígenas al Senado.

El clientelismo y los resultados electorales de la Alcaldía Mayor de Bogotá y el Concejo de Bogotá: un análisis comparado de 2007, 2011 y 2015

La presente investigación tiene como objetivo principal identificar los acuerdos de apoyo político mutuo entre los candidatos al Concejo y los candidatos a la Alcaldía que influyeron en la captación de votos durante los comicios para la Alcaldía Mayor de Bogotá y el Concejo de Bogotá durante 2007, 2011 y 2015. De esta manera, sostiene que los resultados electorales de estos comicios se relacionan de una manera imperfecta. Por ello, se examinará la relación entre los resultados electorales de la Alcaldía y el Concejo de Bogotá con el fin de hallar correlaciones, transferencias de votos y patrones de comportamiento espaciales. Finalmente, esta investigación establecerá relaciones entre los índices de participación y la presencia de redes clientelistas en las UPZ de Bogotá. Se utilizará el método de investigación cualitativo, mediante trabajo de archivo y cartografía electoral, utilizando principalmente fuentes primarias.

Death in the Bolivian High Plateau : Burials and Tiwanaku Society

My Ph.D. dissertation presents a multi-disciplinary analysis of the mortuary practices of the Tiwanaku culture of the Bolivian high plateau, situated at an altitude of c. 3800 m above sea level. The Tiwanaku State (c. AD 500-1150) was one of the most important pre-Inca civilisations of the South Central Andes. The book begins with a brief introductory chapter. In chapter 2 I discuss methodological and theoretical developments in archaeological mortuary studies from the late 1960s until the turn of the millennium. I am especially interested in the issue how archaeological burial data can be used to draw inferences on the social structure of prehistoric societies. Chapter 3 deals with the early historic sources written in the 16th and 17th centuries, following the Spanish Conquest of the Incas. In particular, I review information on how the Incas manifested status differences between and within social classes and what kinds of burial treatments they applied. In chapter 4 I compare the Inca case with 20th century ethnographic data on the Aymara Indians of the Bolivian high plateau. Even if Christianity has affected virtually every level of Aymara religion, surprisingly many traditional features can still be observed in present day Aymara mortuary ceremonies. The archaeological part of my book begins with chapter 5, which is an introduction into Tiwanaku archaeology. In the next chapter, I present an overview of previously reported Tiwanaku cemeteries and burials. Chapter 7 deals with my own excavations at the Late Tiwanaku/early post-Tiwanaku cemetery site of Tiraska, located on the south-eastern shore of Lake Titicaca. During the 1998, 2002, and 2003 field seasons, a total of 32 burials were investigated at Tiraska. The great majority of these were subterranean stone-lined tombs, each containing the skeletal remains of 1 individual and 1-2 ceramic vessels. Nine burials have been radiocarbon dated, the dates in question indicating that the cemetery was in use from the 10th until the 13th century AD. In chapter 8 I point out that considerable regional and/or ethnic differences can be noted between studied Tiwanaku cemetery sites. Because of the mentioned differences, and a general lack of securely dated burial contexts, I feel that at present we can do no better than to classify most studied Tiwanaku burials into three broad categories: (1) elite and/or priests, (2) "commoners", and (3) sacrificial victims and/or slaves and/or prisoners of war. On the basis of such indicators as monumental architecture and occupational specialisation we would expect to find considerable status-related differences in tomb size, grave goods, etc. among the Tiwanaku. Interestingly, however, such variation is rather modest, and the Tiwanaku seem to have been a lot less interested in expending considerable labour and resources in burial facilities than their pre-Columbian contemporaries of many parts of the Central Andes.

Perennial grassland dynamics on fertile plains: Is coexistence mediated by disturbance?

The response of grasslands to disturbance varies with the nature of the disturbance and the productivity of the landscape. In highly productive grasslands, competitive exclusion often results in decreased species richness and grazing may allow more species to coexist. Once widespread, grasslands dominated by Dichanthium sericeum (Queensland bluegrass) and Astrebla spp. (Mitchell grass) occur on fertile plains but have been reduced in extent by cultivation. We tested the effects of exclusion of livestock grazing on these grasslands by comparing the floristic composition of sites in a nature reserve with an adjacent stock reserve. In addition, sites that had been cultivated within the nature reserve were compared with those where grazing but no cultivation had occurred. To partition the effects of temporal variation from spatial variation we sampled sites in three different years (1998, 2002 and 2004). Some 194 taxa were recorded at the nature reserve and surrounding stock routes. Sampling time, the occurrence of past cultivation and livestock grazing all influenced species composition. Species richness varied greatly between sampling periods relating to highly variable rainfall and water availability on heavy clay soils. Native species richness was significantly lower at previously cultivated sites (13-22 years after cultivation), but was not significantly influenced by grazing exclusion. After 8 years it appears that reintroducing disturbance in the form of livestock grazing is not necessary to maintain plant species richness in the reserve. The highly variable climate (e.g. droughts) probably plays an important role in the coexistence of species by negating competitive exclusion and allowing interstitial species to persist.

Introduction, establishment, and potential geographic range of Carmenta sp. nr ithacae (Lepidoptera: Sesiidae), a biological control agent for Parthenium hysterophorus (Asteraceae) in Australia

Parthenium (Parthenium hysterophorus L.), a major weed causing economic, environmental, and human and animal health problems in Australia and several countries in Asia, Africa, and the Pacific, has been a target for biological control in Australia since the mid-1970s. Nine species of insects and two rust fungi have been introduced as biological control agents into Australia. These include Carmenta sp. nr ithacae, a root feeding agent from Mexico. The larvae of C. sp. nr ithacae bore through the stem-base into the root where they feed on the cortical tissue of the taproot. During 1998-2002, 2,816 larval-infested plants and 387 adults were released at 31 sites across Queensland, Australia. Evidence of field establishment was first observed in two of the release sites in central Queensland in 2004. Annual surveys at these sites and nonrelease sites during 2006-2011 showed wide variations in the incidence and abundance of C. sp. nr ithacae between years and sites. Surveys at three of the nine release sites in northern Queensland and 16 of the 22 release sites in central Queensland confirmed the field establishment of C. sp. nr ithacae in four release sites and four nonrelease sites, all in central Queensland. No field establishment was evident in the inland region or in northern Queensland. A CLIMEX model based on the native range distribution of C. sp. nr ithacae predicts that areas east of the dividing range along the coast are more suitable for field establishment than inland areas. Future efforts to redistribute this agent should be restricted to areas identified as climatically favorable by the CLIMEX model.

Low-Complexity Near-MAP Decoding of Large Non-Orthogonal STBCs Using PDA

Non-orthogonal space-time block codes (STBC) from cyclic division algebras (CDA) are attractive because they can simultaneously achieve both high spectral efficiencies (same spectral efficiency as in V-BLAST for a given number of transmit antennas) as well as full transmit diversity. Decoding of non-orthogonal STBCs with hundreds of dimensions has been a challenge. In this paper, we present a probabilistic data association (PDA) based algorithm for decoding non-orthogonal STBCs with large dimensions. Our simulation results show that the proposed PDA-based algorithm achieves near SISO AWGN uncoded BER as well as near-capacity coded BER (within 5 dB of the theoretical capacity) for large non-orthogonal STBCs from CDA. We study the effect of spatial correlation on the BER, and show that the performance loss due to spatial correlation can be alleviated by providing more receive spatial dimensions. We report good BER performance when a training-based iterative decoding/channel estimation is used (instead of assuming perfect channel knowledge) in channels with large coherence times. A comparison of the performances of the PDA algorithm and the likelihood ascent search (LAS) algorithm (reported in our recent work) is also presented.
