El TRATAMIENTO PERIODÍSTICO DE LAS NOTICIAS RELACIONADAS CON LOS VIRUS DEL DENGUE Y ZIKA EN LOS MEDIOS DIGITALES DE HONDURAS (2010-2017)
2019
Resumen: En 1979, se identificó la primera epidemia de dengue en Honduras. En 2010, las autoridades sanitarias y gubernamentales hondureñas decretaron lo que sería la quinta epidemia que afectaba a la población. Cinco años más tarde, una enfermedad emergente llegó al continente americano: el zika. Las entidades internacionales como la Organización Mundial de la Salud y la Organización Panamericana de Salud extendieron la alerta a nivel latinoamericano, en especial a los países propensos por su situación geográfica, climatológica y situación socioeconómica. El objetivo del presente estudio es analizar el contenido de las noticias que se publicaron sobre los virus del dengue y zika en tres di…
150 years of rowing faster: what are the sources of more and more speed?
2015
Rowing has a 150 yr+ competitive history. Examining results from historic races like Oxford-Cambridge (established 1829) and the world championships (established 1893) reveals a linear increase in boat speed by 2-3% per decade. Boat velocity increases if propulsive power is increased and/or power losses are reduced. Over time, the propulsive power capacity of elite rowers has increased. Part of this increase is a result of recruiting athletes from a population that has become taller (1-3 cm per decade) and heavier. Modern world class rowers are typically 190-200 cm tall and weigh 90-100 kg. However, physical capacity does not scale directly with body dimensions but conforms instead to biolo…
Dimensional Latent Structure of Relationship Quality: Results of Three Representative Population Samples
2015
One central issue for every latent construct in psychology (e.g., relationship quality) is its latent nature: Differences in intelligence, for example, are traditionally considered to be dimensional (e.g., when quantifying intelligence by a standardized test score) rather than categorical (distinguishing different categories such as intelligent vs. unintelligent). When considering a categorical construct, such as Down syndrome, on the other hand, the characteristic is qualitative (groups are classified by existence or absence of an extra chromosome) rather than quantitative (varying degrees of Down syndrome). The group bound together by the possession of a certain characteristic (disease, d…
The dialogue between east and west in the construction of gender photography as support of discourse and resistance
2018
En el marco de la globalización, en las nuevas narrativas de género se han producido cambios conceptuales con nuevos posicionamientos críticos y de resistencia. Mujeres creadoras de otras culturas, diferentes al mundo occidental, han trabajado para denunciar situaciones o poner en valor el empoderamiento de las mujeres como protagonistas de su destino. Y es en esta línea donde las mujeres artistas han aportado sus propuestas feministas y de resistencia. Los objetivos de este trabajo se centran en dos ejes conceptuales: a) analizar la situación de las mujeres en el contexto de los países islámicos y b), mostrar, a través del trabajo de fotógrafas procedentes de estos países, como se está con…
Considerations on the Advantages and Disadvantages of Romania's Accession to the European Union
2015
Abstract After nine years from Romania's accession to the European Union, the advantages are sustained with specific statistical markers, which could have been more positive if the effect of certain identified causes (reduced administrative ability, political instability, extended corruption, high tax evasion etc.) would have been diminished. Counterbalancing the benefits of the accession the opinion polls show the disadvantages. If a poll conducted four years prior to the accession showed that 66% of Romania's population considered that the accession to the European Union would produce positive effects, after six years from the accession things have reversed and 58% of Romanians considered…
Niektóre problemy związane z opozycją polityczną
2016
The opposition is an institution of the political regime, whose essential function is to allow alternation of power. According to the political scientist, it is a phenomenon from the sphere of governance, where different imperious and subordinate entities are in a relationship with partially common goals and partly contradictory, but remain always mutually dependent. The importance of the political opposition depends not only on the adopted institutional solutions, but primarily the political culture. Just as every society has the government it deserves, by analogy, the same is also true of the opposition.
Impact of Nonlinear Inductor on Efficiency and Power Losses in a SMPS: a Case Study
2022
This paper proposes a comparative analysis focused on losses in two Switched Mode Power Supplies, adopting a linear inductor and an inductor operated up to saturation, respectively. The use of the nonlinear inductor saves weight and cost on the magnetic material, which is of great interest for automotive applications; however, it increases the peak current and can increase losses. The analysis aims to compare, by simulations, the impact on the efficiency of the different current waveforms throughout the converter. The losses are discussed in detail and calculated for each component of the converters.
Design, implementation and experimental results of an inductive power transfer system for electric bicycle wireless charging
2020
The use of renewable energy and the transformation of transport mode are crucial items for achieving an efficient and clean electrical mobility that allow being competitive on the market. In this context the interface between the power system and the Electric Vehicles (EVs) assumes a strategic role. Specifically, wireless energy transmission, based on Inductive Power Transfer (IPT), is an attractive solution for EVs charging. Moreover, the use of electric bicycles or kick scooters as mode of urban transport is continuously growing because they are lightweight, sustainable, easily parking, flexible and efficient transport devices. Owing to its benefits, the wireless power transfer can be con…
Non-elected Political Elites in the EU
2017
With globalization and Europeanization, profound changes have taken place in the composition and structure of elites. Once solidly tied to the nation state, elites have, following processes of differentiation and specialization, become more transnational than ever before. Their development has been conditioned by the evolving relationship between international, transnational, and national powers. In the European context, key institutional players today include the European Commission, the European Ombudsman and the European Court of Justice as aspiring representatives of the general European interest and the Council of Ministers and member states as representing national interests in the EU…
Relationships between burnout and role ambiguity, role conflict and employee absenteeism among health workers
2014
The aim of this research was to analyze the influence of some psychosocial risk factors in the development of burnout and to analyze the influence of this phenomenon on employee absenteeism. The study sample included 142 health care workers. The data analysis included descriptive statistics and multiple linear regression models. The results confirmed the influence of role ambiguity and role conflict on burnout [F (2.139) = 26.720; p < .001], but the influence of burnout on employee absenteeism was not confirmed. However, a significant and positive relationship has been shown between burnout and employee absenteeism (ß = 0.197; p < .05). In conclusion, the findings of this study support the …
