ON THE EXISTENCE OF LIMIT CYCLES IN OPINION FORMATION PROCESSES UNDER TIME PERIODIC INFLUENCE OF PERSUADERS
2008
This paper concerns a model of opinion formation in a population of interacting individuals under the influence of external leaders or persuaders, which act in a time periodic fashion. The model is formulated within a general framework inspired to a discrete generalized kinetic approach, which has been developed in Ref. 6. It is expressed by a system of non-autonomous nonlinear ordinary differential equations. The dynamics of such a system is investigated and the existence of a globally asymptotically stable periodic solution is analytically proved in three example cases, each one corresponding to a different quantitative choice of the actions of the persuaders. Equivalently, in three part…
Learning Curve in Surgical Treatment of Odontoid Fixation for a Series of Type II C2 Fractures
2019
The craniovertebral junction (CVJ) is a complex anatomical area upon which most of the motion of the upper cervical spine depends [1]. Because of its unique range of motion, the CVJ is subject to several types of traumatic injury; it has been shown that odontoid fractures are the most common ones in the general population and are the most common isolated spinal fractures [2]. Accounting for up to 18% of all cervical fractures, odontoid fractures are the most common ones in elderly patients [3], in whom they account for up to 60% of spinal cord injuries [4].
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…
Achievement perceived, parenting, internet use and adolescent behavior
2019
espanolResumen El uso intensivo de internet puede contribuir a desarrollar disfunciones psicosociales graves en la adolescencia. El objetivo de esta investigacion es analizar las relaciones de la percepcion de eficacia academica con el uso de internet para ocio, los estilos de crianza y los problemas exteriorizados e interiorizados en la adolescencia (agresividad proactiva, reactiva, fisica y verbal, afiliacion a pares rebeldes e inestabilidad emocional). Han participado 762 adolescentes de 12 a 17 anos (M = 13.69; DT = 1.40; varones 52.8%). Utilizan internet en tiempo de ocio entre cero y 98 horas semanales, de ahi que la poblacion se haya distribuido en cuartiles. Las variables se han obt…

Talking about emotions with children at risk of social exclusion: a preliminary study
2016
Resumen Este trabajo tiene como objetivo principal probar de forma preliminar el funcionamiento de un programa de intervención para mejorar las competencias emocionales en niños de entre 9 y 10 años en situación de riesgo de exclusión social. El programa se centra en la mejora de algunos componentes del conocimiento y la regulación emocional. Para ello, se utilizó un diseño pre-experimental de un solo grupo con pretest y postest (N = 14). Los niños asistieron a las sesiones una vez por semana durante cuatro meses. Los resultados mostraron una mejora estadísticamente significativa en manejo de emociones, adaptabilidad e inestabilidad emocional, además de una utilización más efectiva de estra…
Resveratrol post-transcriptionally regulates pro-inflammatory gene expression via regulation of KSRP RNA binding activity
2014
Resveratrol shows beneficial effects in inflammation-based diseases like cancer, cardiovascular and chronic inflammatory diseases. Therefore, the molecular mechanisms of the anti-inflammatory resveratrol effects deserve more attention. In human epithelial DLD-1 and monocytic Mono Mac 6 cells resveratrol decreased the expression of iNOS, IL-8 and TNF-α by reducing mRNA stability without inhibition of the promoter activity. Shown by pharmacological and siRNA-mediated inhibition, the observed effects are SIRT1-independent. Target-fishing and drug responsive target stability experiments showed selective binding of resveratrol to the RNA-binding protein KSRP, a central post-transcriptional regul…
