Democratic Values Transmission

This study addresses the issue of intergenerational transmission of democratic values embedded in social choice rules. We focus on a few rules which have been the focus of social choice theory: plurality, plurality with a runoff, majoritarian compromise, social compromise and Borda rule. We confront subjects with preferences profiles of a hypothetical electorate over a set of four alternatives. Different rules produce different outcomes and subjects decide which alternative should be chosen for the society whose preference profile is shown. We elicit each subject's preferences over rules and his/her parents' and check whether there is any relationship; 186 students and their parents attended the sessions at Istanbul Bilgi University. Overall, we find support for the hypothesis of parental transmission of democratic values and gender differences in the transmitted rule.

Análisis de las interferencias de emisiones LTE sobre servicios DVB-T

[ES]Con la llegada de las tecnologías digitales y los nuevos sistemas de compresión, la misma información puede ser transmitida en menor espacio. Además, el uso de las tecnologías móviles está evolucionando considerablemente, aportando numerosos beneficios. Es esto lo que ha motivado la liberación del espectro radioeléctrico en la banda de 800 MHz para la convivencia del servicio de radiodifusión y el de comunicaciones móviles en bandas adyacentes. Mediante la realización de este proyecto se estudiará el comportamiento de ambos sistemas, para lo que se obtendrán valores de relaciones de protección y umbrales de sobrecarga.

The promoter of cell growth- and RNA protection-associated SND1 gene is activated by endoplasmic reticulum stress in human hepatoma cells

Background: Staphyloccocal nuclease domain-containing protein 1 (SND1) is involved in the regulation of gene expression and RNA protection. While numerous studies have established that SND1 protein expression is modulated by cellular stresses associated with tumor growth, hypoxia, inflammation, heat- shock and oxidative conditions, little is known about the factors responsible for SND1 expression. Here, we have approached this question by analyzing the transcriptional response of human SND1 gene to pharmacological endoplasmic reticulum (ER) stress in liver cancer cells. Results: We provide first evidence that SND1 promoter activity is increased in human liver cancer cells upon exposure to thapsigargin or tunicamycin or by ectopic expression of ATF6, a crucial transcription factor in the unfolded protein response triggered by ER stress. Deletion analysis of the 5'-flanking region of SND1 promoter identified maximal activation in fragment (-934, +221), which contains most of the predicted ER stress response elements in proximal promoter. Quantitative real- time PCR revealed a near 3 fold increase in SND1 mRNA expression by either of the stress- inducers; whereas SND1 protein was maximally upregulated (3.4-fold) in cells exposed to tunicamycin, a protein glycosylation inhibitor. Conclusion: Promoter activity of the cell growth- and RNA-protection associated SND1 gene is up-regulated by ER stress in human hepatoma cells.

Atmospheric Measurement Techniques Volume 8, Issue 5, 27 May 2015, Pages 2183-2193 Estimating reflectivity values from wind turbines for analyzing the potential impact on weather radar services (Article) Angulo, I.a, Grande, O.a, Jenn, D.b, Guerra, D.a, De La Vega, D.a a University of the Basque Country (UPV/EHU), Bilbao, Spain b Naval Postgraduate School, Monterey, United States View references (28) Abstract The World Meteorological Organization (WMO) has repeatedly expressed concern over the increasing number of impact cases of wind turbine farms on weather radars. Current signal processing techniques to mitigate wind turbine clutter (WTC) are scarce, so the most practical approach to this issue is the assessment of the potential interference from a wind farm before it is installed. To do so, and in order to obtain a WTC reflectivity model, it is crucial to estimate the radar cross section (RCS) of the wind turbines to be built, which represents the power percentage of the radar signal that is backscattered to the radar receiver.

For the proposed model, a representative scenario has been chosen in which both the weather radar and the wind farm are placed on clear areas; i.e., wind turbines are supposed to be illuminated only by the lowest elevation angles of the radar beam.

This paper first characterizes the RCS of wind turbines in the weather radar frequency bands by means of computer simulations based on the physical optics theory and then proposes a simplified model to estimate wind turbine RCS values. This model is of great help in the evaluation of the potential impact of a certain wind farm on the weather radar operation.

El soleamiento en las fachadas, técnicas para su reducción y pre dimensionamiento.

[EU]Lan honen helburu nagusia eraikuntzan gehituko diren argi-babeski sistema mota desberdinak aurkeztea da, bertan ematen den energia kontsumoa murrizteko asmoz. Izan ere, argi naturalaren erabilpen egoki batek eraikinaren efizientzia hobetzera eramango gaitu. Horretarako, ezinbestekoa izango da baliabide hau behar bezala ezagutzea, argitasuna eta beharrezko babesa eskaintzeko, eta ondorioz, energia aurreztea lortzeko. Babes sistema egokiena aukeratu baino lehen, aldez aurretik sortu izan diren argi-babeski mota desberdinak aztertu izan dira. Horrez gain, eguzki erradiazioa neurtzeko metodo grafiko eta analitikoak ere aztertu dira. Ondoren, Ecotect programak eskaintzen dituen simulazioei esker, eguzki erradiazioaren datu zehatzagoak lortzeko asmoz, ikasketa horretan erabiliko den eraikinaren kokapena, orientazioa eta ezaugarriak erabaki dira. Behin prototipoa definituta, programa bidez lau babes sistema mota desberdinak aztertu dira, horrela babesik gabeko eraikinean lortutako datuak alderatzeko. Azterketa Bilbo eta Sevillan egitea erabaki izan da. Izan ere, bi hiriburu hauek klimatologian duten desberdintasuna argi-babeskien aukeraketan duen eragina aztertzeko aukeratu dira, gainera, orientazioak eta argi babeskien dimentsioek ere izan dute zer esana aukeraketa garaian. Horrez gain, argi-babeskiek sortutako itzala ere aztertu izan da. Horrela, sistema hauen jarrera orokorra ikusi daiteke, eta beraz, uda garaian babesteko eta negu garaian eguzki izpiak sartzen uzteko duten ahalmena ikusi da. Bukatzeko, aurretik lortutako datu guztiei esker, eta bai kokapena zein orientazioa kontutan hartuz, babes sistema egokiena aukeratu da, jakinik ezinbestekoa dela argitasuna, babesa eta aurrezte energetikoaren arteko oreka egoki bat lortzea.
