Technology changes rapidly over years providing continuously more options for computer alternatives and making life easier for economic, intra-relation or any other transactions. However, the introduction of new technology “pushes” old Information and Communication Technology (ICT) products to non-use. E-waste is defined as the quantities of ICT products which are not in use and is bivariate function of the sold quantities, and the probability that specific computers quantity will be regarded as obsolete. In this paper, an e-waste generation model is presented, which is applied to the following regions: Western and Eastern Europe, Asia/Pacific, Japan/Australia/New Zealand, North and South America. Furthermore, cumulative computer sales were retrieved for selected countries of the regions so as to compute obsolete computer quantities. In order to provide robust results for the forecasted quantities, a selection of forecasting models, namely (i) Bass, (ii) Gompertz, (iii) Logistic, (iv) Trend model, (v) Level model, (vi) AutoRegressive Moving Average (ARMA), and (vii) Exponential Smoothing were applied, depicting for each country that model which would provide better results in terms of minimum error indices (Mean Absolute Error and Mean Square Error) for the in-sample estimation. As new technology does not diffuse in all the regions of the world with the same speed due to different socio-economic factors, the lifespan distribution, which provides the probability of a certain quantity of computers to be considered as obsolete, is not adequately modeled in the literature. The time horizon for the forecasted quantities is 2014-2030, while the results show a very sharp increase in the USA and United Kingdom, due to the fact of decreasing computer lifespan and increasing sales.

Contemporary Central American fiction has become a vital project of revision of the tragic events and the social conditions in the recent history of the countries from which they emerge. The literary projects of Sergio Ramirez (Nicaragua), Dante Liano (Guatemala), Horacio Castellanos Moya (El Salvador), and Ramon Fonseca Mora (Panama), are representative of the latest trends in Central American narrative. These trends conform to a new literary paradigm that consists of an amalgam of styles and discourses, which combine the testimonial, the historical, and the political with the mystery and suspense of noir thrillers. Contemporary Central American noir narrative depicts the persistent war against social injustice, violence, criminal activities, as well as the new technological advances and economic challenges of the post-war neo-liberal order that still prevails throughout the region. ^ Drawing on postmodernism theory proposed by Ihab Hassan, Linda Hutcheon and Brian MacHale, I argued that the new Central American literary paradigm exemplified by Sergio Ramirez's El cielo llora por mí, Dante Liano's El hombre de Montserrat, Horacio Castellanos Moya's El arma en el hombre and La diabla en el espejo , and Ramon Fonseca Mora's El desenterrador, are highly structured novels that display the characteristic marks of postmodern cultural expression through their ambivalence, which results from the coexistence of multiple styles and conflicting ideologies and narrative trends. The novels analyzed in this dissertation make use of a noir sensitivity in which corruption, decay and disillusionment are at their core to portray the events that shaped the modern history of the countries from which they emerge. The revolutionary armed struggle, the state of terror imposed by military regimes and the fight against drug trafficking and organized crime, are among the major themes of these contemporary works of fiction, which I have categorized as perfect examples of the post-revolutionary post-modernism Central American detective fiction at the turn of the 21st century.^

This article evaluates the performance of public service broadcasters in the area of children’s television in Italy and Spain. It asks: how distinctive is the output of public service children’s channels? As core area of public service provision, children’s television represents an important testing ground for wider debates about the distinctiveness of public service broadcasting in a digital age. Public broadcasters in Southern Europe have historically been more vulnerable to market pressure than their counterparts in continental and Northern Europe, and this is believed to have impacted negatively on their ability to maintain a distinctive public service profile. After engaging with debates on distinctiveness in order to develop a framework for the analysis, the article presents the results of a two-week analysis of the TV schedules of the main children’s channels operating in the two countries. It finds evidence that in both countries the output of public service children’s channels is distinctive to a degree, but also that there are important gaps in public service provision as well as some significant differences between the public service children’s channels analysed.

Mussolini thought movies were the strongestweapon; however, the efficiency of cinematographic propaganda on people did not work as well as expected,especially nonfiction.

Analysis of the word lancea, of Hispanic origin after Varro, and of place names, people´s names and personal names derived from it. It confirms that the spear was the most important weapon in the Bronze Age, belonging to the iuventus and used as heroic and divine symbol. This analysis confirms also the personality of the Lusitanians, a people related to the Celts but with more archaic archaeological, linguistic and cultural characteristics originated in the tradition of the Atlantic Bronze in the II millennium BC. It is also relevant to better know the organisation of Broze and Iron Age societies and the origin of Indo-Europeans peoples in Western Europe and of pre-Roman peoples of Iberia.

Durante el siglo XIII se produjo una sucesión de revueltas que supuso la desaparición del Imperio almohade y su sustitución por poderes regionales en al-Andalus, el Magreb y el Magreb al-Aqsà. La historiografía ha presentado el surgimiento y pugna entre estos poderes como un fenómeno social, político e, incluso, cultural y religioso, con el que se ha podido explicar su aniquilación o marginalización. Este trabajo pretende contextualizar los hechos desde una perspectiva medioambiental, de forma que la desintegración del califato almohade, el surgimiento de aquellos poderes y la progresión de los reinos cristianos en la península ibérica puedan entenderse desde una visión global de cambio climático y una posible crisis agrícola.

Tucídides es una de nuestras mejores fuentes de información para conocer la práctica argumentativa de la deliberación democrática. En este trabajo se analiza uno de los vicios que, según el historiador, haría su aparición en la escena política ateniense a la muerte de Pericles: la instrumentalización del miedo para obtener la victoria momentánea en la asamblea. El temor prudente, que fuera una arma periclea para conducir la deliberación racional en aras del bien común, habría desaparecido siendo sustituido por el amedrentamiento del rival, la calumnia, el obstruccionismo y la parálisis de la confrontación dialéctica. Instauradas en la ciudad la desconfianza y la sospecha de ocultación, los golpistas del 411 hallaron el terreno abonado para callar las voces contrarias y, gracias al silencio, instaurar el terror.

Este artículo analiza la existencia de un posible ritual en la antigua Macedonia que fuese similar al Akîtu babilonio. Pensamos que la victoria de Zeus sobre sus enemigos en la gigantomaquia y tifonomaquia fue celebrada por los reyes macedonios para fortalecer su posición en el poder. Aunque no hay evidencias directas de ello, tenemos una serie de diferentes fuentes en las cuales los macedonios están relacionados directa o indirectamente con Tifón y los gigantes. Además, la estratégica importancia del monte Olimpo para los macedonios nos hace pensar que la victoria de Zeus sobre las fuerzas del mal fue conmemorada de alguna forma por ellos.

Bajo el paradigma de modernización y desarrollo norteamericano -y en un contexto de Guerra Fría-, durante la década de 1960 se adecuaron a la realidad chilena programas de control de natalidad que no sólo buscaron disminuir las altas tasas de mortalidad materno infantil, sino que además respondieron al proyecto de seguridad hemisférica norteamericana de contención a posibles revoluciones populares en países del Tercer Mundo.
