Cyber-behavior and emotional dependency in young couples

The use of the ICT and the cyber media is leading to new forms of socialization and communication among youth. Virtual environment has become a new context for relating to other people which also includes the establishment and development of couple relationships. At the same time, couple relationships\ud in youth can be very satisfactory, although many studies also described the existence of different problems such as inadequate behaviors towards the partners or emotional dependency. Thus, the current work describes the use of different cyber media among youth and its relationship to the levels of emotional dependency. First, a questionnaire on the use of cyber media in oneself and perceived in a partner was answered by the participants. At the same time, the IRIDS-100 questionnaire for the assessment of the emotional dependency was responded.\ud Both instruments were answered by 100 students between 19 and 32 years old, enrolled in the University of Córdoba. Results showed frequent use of WhatsApp, Facebook, Twitter and Youtube in oneself and also perceived in the partner. Moreover, positive correlations were found between its use in oneself and perceived in the partner and emotional dependency. Taking into account that the cyber media have changed the way of relating among young people, with their peers and their couples, the results of the current study contribute to this topic suggesting\ud at the same time new lines of studies related to the emotional dependency expressed through the cyber media

Precios de transferencia y la UE: revisión de las medidas adoptadas

La reciente adopción por parte del Consejo de Ministros de Economía y Finanzas de la UE, por medio del Código de Conducta, de las recomendaciones del Foro Conjunto de Precios de Transferencia para la efectiva aplicación del Convenio de Arbitraje relativo a la supresión de la doble imposición que emana de los ajustes por operaciones vinculadas entre sociedades residentes en diferentes países de la UE supone un claro avance en la eliminación de las barreras fiscales con las que se encuentran los operadores comunitarios en sus operaciones intra-grupo dentro del Mercado Único. El artículo realiza, en primer lugar, un análisis del articulado del Convenio de Arbitraje para posteriormente adentrarse en el avance que supone la aceptación de las recomendaciones del Foro y finalmente plantear las cuestiones que deberán resolverse en los próximos años

Revisión del régimen fiscal de las reestructuraciones: propuestas de modificación

The object of this article is to highlight various aspects of our tax regulations that are related to restructurings which, in our opinion, should be amended in order to conform to the recent commercial regulations concerning restructurings or to EU law, or simply for technical tax reasons. The proposals for modification that we comment on do not only apply to the legal texts, but also to the criteria for interpretation maintained by the Tax Administration, being the Spanish Directorate of Taxes (Dirección General de Tributos) or the Economic Administrative Courts (Tribunales Económico-Administrativos), used in the application of the regulations which govern restructurings. We believe that the amendments that we propose are necessary, as well as desirable, since the aim of such amendments is to help businesses restructure without the tax regime curbing or obstructing its achievement, as well as to achieve legal certainty.El presente artículo tiene por objeto poner de manifiesto aquellos aspectos de nuestra normativa fiscal relativos a las operaciones de reestructuración que, a nuestro juicio, sería conveniente que fueran objeto de modificación, ya sea para su adecuación a la reciente normativa mercantil en materia de reestructuraciones, para su adaptación al Derecho de la Unión Europea, o bien por meras razones de técnica tributaria. Las propuestas de modificación que comentamos se refieren no únicamente a los textos legales, sino también a los criterios interpretativos mantenidos por la Administración tributaria, ya sea la Dirección General de Tributos o los Tribunales Económico-Administrativos, en aplicación de las normas que regulan las operaciones de reestructuración. Entendemos que estas modificaciones que proponemos son necesarias, al tiempo que convenientes, dado que la finalidad que se persigue con las mismas es facilitar que las empresas puedan llevar a cabo operaciones de reestructuración sin que la fiscalidad suponga un freno o un obstáculo para la consecución de las mismas, así como ganar en seguridad jurídica

Cambios edáficos en las Marismas de Doñana y su relación con la invasión de Azolla filiculoide

2 páginas, 7 referencias. En el Capítulo: Degradación de suelos y desertificación. Simposio celebrado en Fuerteventura, 16-20, septiembre, 2007. Los editores son del Departamento de Edafología y Geología, Universidad de La Laguna.La Marisma de de Doñana es una extensa planicie dominada por suelos arcillosos, calcáreos y salinos (Clemente et al., 1998) que se inunda estacionalmente -por efecto de la lluvia y de algunos arroyos- y acoge a una de las poblaciones de aves acuáticas más importantes de Europa (Clemente et al. 2004). En 2001 uno de los autores (J.L. Espinar) documentó por primera vez la presencia del helecho de origen americano Azolla filliculoides, una especie invasora con capacidad para fijar el N atmosférico, que acabó extendiéndose por el humedal en los años siguientes (Cobo y Bañuls, 2005) En este trabajo se analizan los cambios ambientales ocurridos en la marisma de Doñana con anterioridad a la invasión, en relación con lo acaecido en anteriores episodios de invasión por Azolla de otras áreas naturales.Peer reviewe

Long-term stability of surgical-orthodontic correction of class III malocclusions with long-face syndrome

Objectives: In the first place, to evaluate skeletal changes of the maxilla and mandible induced by surgical-orthodontic correction of malocclusions class III with long-face syndrome and secondly, to analyze the stability of these skeletal changes in the long term (more than 6 years). Design of Study: A retrospective, unicentric and longitudinal study of 19 patients who had undergone surgical and orthodontic therapy for class III skeletal malocclusion with long-face syndrome was undertaken. A cephalometric analysis based on 8 angle measurements, and statistical analyses at three different points in time (before orthodontic treatment, after orthognathic surgery and after a retention period of at least 6 years) were carried out. Results: The changes produced following surgery show that, with the exception of the maxillary plane and the facial axis, all other variables presented changes of great statistical difference. Conclusions: Skeletal changes after orthodontic-surgical correction present maxillary advance, mandibular regression and mandibular anterorotation. The angles that represent the mandibular vertical position (ramus angle, goniac angle and mandibular plane angle) showed statistically significant relapses and no stability in contrast to the facial axis

On the contribution of qualitative analysis in mathematical modeling of plasmid-mediated ceftiofur resistance

The acquisition of antibiotic resistance due to the consumption of food contaminated with resistant strains is a public health problem that has been increasing in the last decades. Mathematical modeling is contributing to the solution of this problem. In this article we performed the qualitative analysis of a mathematical model that explores the competition dynamics in vivo of ceftiofur-resistant and sensitive commensal enteric Escherichia coli (E. coli) in the absence and during parenteral ceftiofur therapy within the gut of cattle, considering the therapeutic effects (pharmacokinetics (PK)/pharmacodynamics (PD)) in the outcome of infection. Through this analysis, empirical properties obtained through in vivo experimentation were verified, and it also evidenced other properties of bacterial dynamics that had not been previously shown. In addition, the impact of PD and PK has been evaluated

External apical root resorption in maxillary root-filled incisors after orthodontic treatment : a split-mouth design study

Introduction: The purpose of this study was to compare, in a split mouth design, the external apical root resorption (EARR) associated with orthodontic treatment in root-filled maxillary incisors and their contralateral teeth with vital pulps. Methodology: The study sample consisted of 38 patients (14 males and 24 females), who had one root-filled incisor before completion of multiband/bracket orthodontic therapy for at least 1 year. For each patient, digital panoramic radiographs taken before and after orthodontic treatment were used to determine the root resortion and the proportion of external root resorption (PRR), defined as the ratio between the root resorption in the endodontically treated incisor and that in its contralateral incisor with a vital pulp. The student?s t-test, chi-square test and logistic regression analysis were used to determine statistical significance. Results: There was no statistically significant difference (p > 0.05) between EARR in vital teeth (1.1 ± 1.0 mm) and endodontically treated incisors (1.1 ± 0.8 mm). Twenty-six patients (68.4%) showed greater resorption of the endodontically treated incisor than its homolog vital tooth (p > 0.05). The mean and standard deviation of PPR were 1.0 ± 0.2. Multivariate logistic regression suggested that PRR does not correlate with any of the variables analyzed. Conclusions: There was no significant difference in the amount or severity of external root resorption during orthodontic movement between root-filled incisors and their contralateral teeth with vital pulps
