Análisis del proceso de construcción de la Democracia en el Estado de la República Democrática Federal de Etiopía como instrumento de poder del Primer Ministro Meles Zenawi. Periodo 1994 -2010.

La presente monografía pretende estudiar la reproducción de una estructura autoritaria de poder, bajo un régimen político democrático en el mandato del ex Primer Ministro Meles Zenawi en Etiopía. Para esto se analizó los factores que han imposibilitado la construcción de la democracia y han hecho perdurar prácticas autoritarias en el gobierno etíope a la luz de la Teoría de la Estructuración de Anthony Giddens y el concepto de Patrimonialismo.

Price movement in the Brazilian land market (1994-2010): an analysis in the light of post-Keynesian theory

ABSTRACT The present study aims to evaluate crop, pasture and forest land prices in Brazil, between 1994 and 2010, in the light of Post-Keynesian theory. The results provide evidence that land, more than just a simple factor of production, must be conceived of as an economic asset. In fact, the price of rural land is determined not only by the expected profitability deriving from agricultural activities but also by the agents' expectations about its future appreciation and liquidity in an economic environment permeated with uncertainty. In this context, as an object of speculation, land has been particularly important as a store of value.

Brasil y su actual condición de potencia en la política mundial: entre juegos de percepciones y definiciones académicas (1994-2010)

El estudio aborda desde una perspectiva ampliada, el análisis de la actual condición de potencia de la República Federativa de Brasil. A través del complemento entre los planteamientos neorrealistas, la propuesta de la geo-economía y el abordaje constructivista, además de los muy valiosos aportes de los estudios sobre «securitización» y «europeización»; esta investigación sostiene que la potencia brasileña emerge producto de la articulación de los factores tanto materiales como subjetivos del poder. La anterior sinergia deriva en la creación del concepto de «potencialización», el cual permite comprender la construcción de la potencia de Brasil como un proceso, propuesta conceptual que será útil para futuros estudios sobre este tema.

Marchas e contramarchas na luta pela moradia na Terra Firme (1979-1994)

A dissertação historiou a luta pela moradia desenvolvida na Bacia Hidrográfica do Igarapé Tucunduba, especificamente no bairro da Terra Firme entre os anos de 1979 a 1994. A pesquisa teve como propósito analisar as contribuições produzidas nesse processo, que projetaram elementos de resistência e organização social por parte dos moradores daquele lugar. Utilizamos prioritariamente fontes jornalísticas e entrevistas com lideranças. Durante a década de oitenta, acontecimentos políticos agitaram o país, promovidos pelo retorno das multidões às praças e colocaram na ordem do dia um conjunto de demandas sociais, dentre as quais a reforma urbana. Em Belém, o Movimento de Titulação e Urbanização da Área do Tucunduba – MOTUAT, tornou-se uma das referências sociais ao tornar-se representante das reivindicações populares na luta pelo direito de morar em terras consideradas da Universidade Federal do Pará - UFPA.

Hradec Králové total ozone assimilated time series from 1961 to 2010

Homogenized data series of total ozone measurements taken by the regularly and well calibrated Dobson and Brewer spectrophotometers at Hradec Králové (Czech) and the data from the re-analyses ERA-40 and ERA-Interim were assimilated and combined to investigate differences between the particular data sets over Central Europe, the NH mid-latitudes. The Dobson-to-Brewer transfer function and the algorithm for approximation of the data from the re-analyses were developed, tested and applied for creation of instrumentally consistent and completed total ozone data series of the 50-year period 1961-2010 of observations. The assimilation has reduced the well-known seasonal differences between Dobson and Brewer data below the 1% calibration limit of the spectrophotometers. Incorporation of the ERA-40 and ERA-Interim total ozone data on days with missing measurements significantly improved completeness and reliability of the data series mainly in the first two decades of the period concerned. Consistent behaviour of the original and assimilated data sets was found in the pre-ozone-hole period (1961-1985). In the post-Pinatubo (1994-2010) era the data series show seasonal differences that can introduce uncertainty in estimation of ozone recovery mainly in the winter-spring season when the effect of the Montreal Protocol and its Amendments is expected. All the data sets confirm substantial depletion of ozone also in the summer months that gives rise to the question about its origin. The assimilated and completed data series of total ozone will be further analyzed to quantify chemical ozone losses and contribution of natural atmospheric processes to the ozone depletion over the region. This case study points out importance of selection and evaluation of the quality and consistency of the input data sets used in estimation of long-term ozone changes including recovery of the ozone layer over the selected areas.

MÍDIA E MARKETING POLÍTICO: A CAMPANHA ELEITORAL DE FERNANDO HENRIQUE CARDOSO PARA PRESIDENTE, NAS PÁGINAS DA REVISTA VEJA EM 1994

Esta dissertação tem como objetivo verificar, de acordo com o conceito de marketing político, como se deu a construção da imagem pública do ex-presidente Fernando Henrique Cardoso na revista Veja durante as eleições presidenciais de 1994. Para tanto, analisou-se 19 edições desse periódico, todas relativas ao período de junho a outubro do referido ano. Estudou-se a propaganda ideológica e suas categorias, como codificação, controle ideológico, contrapropaganda e difusão, presentes no material empírico analisado. Este trabalho desenvolveu-se à luz dos procedimentos metodológicos referentes ao Estudo de Caso enquanto tipo ou estratégia de pesquisa. Entre as técnicas para a coleta de dados, realizou-se a Análise de Conteúdo de natureza quantitativa e qualitativa dos dados pesquisados e entrevista com o próprio ex-presidente. Por meio deste estudo obteve-se os seguintes resultados: Fernando Henrique Cardoso teve o maior volume em centímetro/coluna em relação ao seu opositor, o candidato Luiz Inácio Lula da Silva. Em relação aos códigos utilizados nas matérias analisadas, o volume maior em centímetro/coluna ocorreu no código linguístico, significando que a revista Veja deu mais ênfase às palavras, às frases e aos parágrafos que compõem as estruturas articuladas, segundo os padrões históricos e culturais da língua portuguesa. No que diz respeito aos gêneros informativos, o volume maior em centímetro/coluna foi em reportagem, isso significa que a revista enfatizou os fatos que repercutiram e produziram efeitos na sociedade, e que foram percebidos pela revista. Concluise que as matérias publicadas fortaleceram significativamente a sua imagem perante os leitores da Veja, favorecendo-o em relação ao seu opositor, mas não chegaram a elegê-lo.(AU)

Gender and media: where do we stand today?

Nowadays, the public discourses about gender equality are commonly accepted in Western society. In fact, we live in an era of “equality illusion” (Banyard, 2010) because the mainstream discourses incorporate gender in the agenda, conveying the message that feminist struggles are unnecessary today. At the same time, postfeminism (McRobbie, 2004) gains importance and demonstrates the intricacies of a neoliberal, highly individualist culture that subtly imprisons the freedoms that it is supposed to grant (Gill & Scharff, 2011). However, back in 1978, Gaye Tuchman used the expression “symbolic annihilation” to refer to how the media represented women. The author refers to a “symbolic annihilation” because sometimes it is so hidden and subtle that it becomes difficult to perceive – and to be fought. Much has improved since then; yet a lot remains the same. Over the past decades there have been marked changes in gender relations, in feminist activism, in the (media) communication industry and in society in general (Byerly, 2013; Carter, Steiner & McLaughlin, 2015; Gallagher, 2014; Gallego, 2013; Krijnen, Álvares & Van Bauwel, 2011; Krijnen & Van Bauwel, 2015; Lobo, Silveirinha, Subtil, & Torres, 2015; Ross, 2009; Silveirinha, 2001; Van Zoonen, 1994, 2010). Now, in a globalised and media saturated world, the gendered picture is, consequently, different. The contemporary grammar is marked by diverse and complex tensions (van Zoonen, 2010).

Anomalías del perfil vertical de temperatura del punto fijo Paita como indicador de la propagación de Ondas Kelvin

La propagación frecuente de ondas Kelvin de hundimiento o “downwelling” atrapadas a la costa, suele caracterizar la ocurrencia de El Niño costero frente al Perú. Estas ondas causan la elevación del nivel del mar y se asocian a la profundización de la estructura vertical sub-superficial de la columna de agua, influenciando en la fertilidad del afloramiento costero. En el presente estudio se describe la variabilidad mensual de la estructura vertical de la columna de agua frente a la costa de Paita-Piura y se comparan con anomalías del nivel del mar frente a Galápagos y en la costa norte del país. Para tal propósito se calculó una climatología con la base de datos histórica de temperatura del punto fijo de Paita, puesta a disposición por el Monterey Bay Aquarium Research Institute (MBARI), para el periodo 1994-2010. Luego de la remoción de datos extremos dudosos, se realizó una interpolación vertical de los datos cada 10 m y una climatología de los datos a frecuencia mensual. La serie de tiempo de anomalía de temperatura muestra una gran consistencia con el arribo de ondas Kelvin a las costa de Sudamérica, por lo cual su monitoreo es de gran utilidad para la alerta temprana de El Niño.

The impact of FTAs on MENA trade in agricultural and industrial products

This paper analyses the impact of Free Trade Agreements (FTAs) on Middle East and North African Countries (MENA) trade for the period 1994-2010. The analysis distinguishes between industrial and agricultural trade to take into account the different liberalisation schedules. An augmented gravity model is estimated using up-to-date panel data techniques to control for all time-invariant bilateral factors that influence bilateral trade as well as for the so-called multilateral resistance factors. We also control for the endogeneity of the agreements and test for self-selection bias due to the presence of zero trade in our sample. The main findings indicate that North-South-FTAs and South-South- FTAs have a differential impact in terms of increasing trade in MENA countries, with the former being more beneficial in terms of exports for MENA countries, but both showing greater global market integration. We also find that FTAs that include agricultural products, in which MENA countries have a clear comparative advantage, have more favourable effects for these countries than those only including industrial products.

Pricing anomalies in the Finnish stock market

The aim of this thesis is to examine whether the pricing anomalies exists in the Finnish stock markets by comparing the performance of quantile portfolios that are formed on the basis of either individual valuation ratios, composite value measures or combined value and momentum indicators. All the research papers included in the thesis show evidence of value anomalies in the Finnish stock markets. In the first paper, the sample of stocks over the 1991-2006 period is divided into quintile portfolios based on four individual valuation ratios (i.e., E/P, EBITDA/EV, B/P, and S/P) and three hybrids of them (i.e. composite value measures). The results show the superiority of composite value measures as selection criterion for value stocks, particularly when EBITDA/EV is employed as earnings multiple. The main focus of the second paper is on the impact of the holding period length on performance of value strategies. As an extension to the first paper, two more individual ratios (i.e. CF/P and D/P) are included in the comparative analysis. The sample of stocks over 1993- 2008 period is divided into tercile portfolios based on six individual valuation ratios and three hybrids of them. The use of either dividend yield criterion or one of three composite value measures being examined results in best value portfolio performance according to all performance metrics used. Parallel to the findings of many international studies, our results from performance comparisons indicate that for the sample data employed, the yearly reformation of portfolios is not necessarily optimal in order to maximally gain from the value premium. Instead, the value investor may extend his holding period up to 5 years without any decrease in long-term portfolio performance. The same holds also for the results of the third paper that examines the applicability of data envelopment analysis (DEA) method in discriminating the undervalued stocks from overvalued ones. The fourth paper examines the added value of combining price momentum with various value strategies. Taking account of the price momentum improves the performance of value portfolios in most cases. The performance improvement is greatest for value portfolios that are formed on the basis of the 3-composite value measure which consists of D/P, B/P and EBITDA/EV ratios. The risk-adjusted performance can be enhanced further by following 130/30 long-short strategy in which the long position of value winner stocks is leveraged by 30 percentages while simultaneously selling short glamour loser stocks by the same amount. Average return of the long-short position proved to be more than double stock market average coupled with the volatility decrease. The fifth paper offers a new approach to combine value and momentum indicators into a single portfolio-formation criterion using different variants of DEA models. The results throughout the 1994-2010 sample period shows that the top-tercile portfolios outperform both the market portfolio and the corresponding bottom-tercile portfolios. In addition, the middle-tercile portfolios also outperform the comparable bottom-tercile portfolios when DEA models are used as a basis for stock classification criteria. To my knowledge, such strong performance differences have not been reported in earlier peer-reviewed studies that have employed the comparable quantile approach of dividing stocks into portfolios. Consistently with the previous literature, the division of the full sample period into bullish and bearish periods reveals that the top-quantile DEA portfolios lose far less of their value during the bearish conditions than do the corresponding bottom portfolios. The sixth paper extends the sample period employed in the fourth paper by one year (i.e. 1993- 2009) covering also the first years of the recent financial crisis. It contributes to the fourth paper by examining the impact of the stock market conditions on the main results. Consistently with the fifth paper, value portfolios lose much less of their value during bearish conditions than do stocks on average. The inclusion of a momentum criterion somewhat adds value to an investor during bullish conditions, but this added value turns to negative during bearish conditions. During bear market periods some of the value loser portfolios perform even better than their value winner counterparts. Furthermore, the results show that the recent financial crisis has reduced the added value of using combinations of momentum and value indicators as portfolio formation criteria. However, since the stock markets have historically been bullish more often than bearish, the combination of the value and momentum criteria has paid off to the investor despite the fact that its added value during bearish periods is negative, on an average.

Análisis del arrendamiento como alternativa en la política de vivienda de interés social en Colombia. Lecciones y reflexiones aprendidas a partir de la experiencia de Sudáfrica

Los esfuerzos de la presente investigación se concentran en el cumplimiento del objetivo principal, el cual consiste en analizar el arrendamiento como un programa que puede ser incorporado en la política de vivienda en Colombia, para dar respuesta de forma transitoria y/o temporal de alojamiento a los hogares con ingresos iguales o inferiores a dos salarios mínimos, ya que actualmente la política sectorial no incorpora esta forma tenencia de la vivienda para ofertar soluciones habitacionales. El arrendamiento tiene rasgos interesantes e importantes de destacar, tales como que él mismo constituye una forma de tenencia de vivienda eminentemente urbana. Además, es un mercado al que acuden todos los estratos socioeconómicos, por lo cual no es un mercado segregado. Igualmente, al relacionar ésta tenencia con el territorio y por ende con la economía espacial, se puede decir que no existe segregación socio-espacial muy pronunciada frente a la distribución urbana de la tenencia de la vivienda en arrendamiento. En este sentido, la tenencia de la vivienda en forma de arrendamiento se presenta en todo el territorio urbano de Cali, Medellín y Bogotá.
