Global Perspective on Marital Satisfaction
2020
Across the world, millions of couples get married each year. One of the strongest predictors of whether partners will remain in their relationship is their reported satisfaction. Marital satisfaction is commonly found to be a key predictor of both individual and relational well-being. Despite its importance in predicting relationship longevity, there are relatively few empirical research studies examining predictors of marital satisfaction outside of a Western context. To address this gap in the literature and complete the existing knowledge about global predictors of marital satisfaction, we used an open-access database of self-reported assessments of self-reported marital satisfaction wit…
Otolith chemical composition suggests local populations of Antarctic silverfish Pleuragramma antarctica (Boulenger, 1902) around Antarctica are expos…
2021
The Antarctic silverfish Pleuragramma antarctica is a key species in the Southern Ocean ecosystem, and it is potentially threatened by the climate change affecting Antarctic ecosystems. Assessing the possible exposure to similar or different environmental conditions at early life stages and gathering information about connectivity or segregation between local populations of P. antarctica can be key for planning sound management strategies for this species. By using Laser Ablation Inductively Coupled Plasma Mass Spectrometry, we characterized the otolith chemical composition of 163 adult Antarctic silverfish collected from three areas located thousands of kilometers apart from each other: Ca…
Intra-urban residential differentiation in the post-Soviet city: the case of Riga, Latvia
2014
Cities in many Central and Eastern European (CEE) countries have transformed rapidly since the political and socio-economic restructuring started in the early 1990s. Economi reforms, growing income inequalities, changes in housing system and selective residential mobility are resulting in increasing socio-spatial differentiation among urban neighbourhoods also in Riga. In addition, litt le is known about the ethnic dimension of intra-urban residential differentiation, despite the existence of sizeable minority populations. The focus on ethnicity is important, since Riga is the only capital city in the Baltic States where the ethnic majority is outnumbered by the non-Latvian minority. This p…
Current understanding of genetic polymorphisms as biomarkers for risk of biological complications in implantology
2018
Background In the last decade, multiple studies have been published that analyze the relationship between the risk of experiencing biological complications with implants and the presence of certain types of genetic polymorphisms. In the present report, we analyze the controversies that have arisen from this important area of investigation and synthesize the most prominent aspects of knowledge related to this possible etiopathogenic relationship. Material and methods For this review, the biomedical databases PubMed-Medline, SciELO, and DOAJ were used. Different search strategies were employed, from which 298 articles initially emerged. After refinement of the search, 55 articles published be…
Origination and extinction patterns of mammals in three central Western Mediterranean islands from the Late Miocene to Quaternary
2008
Abstract An overview of the population histories of three insular realms (Gargano palaeo-archipelago, Sardinia–Maritime Tuscany palaeo-bioprovince and the Sicilian insular complex) during the Late Miocene and Quaternary are here presented. The complexity of biodiversity changes in the islands is analysed to propose an interpretation of origination and extinction patterns. The study highlighted several important aspects of insular faunas. Evolutionary radiations were found to contribute significantly only to the Gargano faunal diversity, likely because the area was an archipelago at the time. Another interesting result is that large and small mammals do not disperse and become extinct all at…
Primary Epithelial Ovarian Neoplasms: New Concepts Concerning Origin, Pathogenesis and Classification Based on Morphology, Immunomarkers, Molecular F…
2011
The World Health Organization (WHO) classification of ovarian tumors, which first appeared in 1983 and since then has undergone a number of revisions, is based on morphologic features as well as on the concept that each category of ovarian tumors develops from a specific ovarian cell. According to this histogenetic classification, all the epithelial ovarian neoplasms are derived from the ovarian surface epithelium and/or from ovarian inclusion cysts, which are lined by the above epithelial cells. In recent years, a new approach to morphologic data, increasing presumptive evidence that the cell of origin of most, if not all, ovarian epithelial tumors may be extraovarian, especially from fall…
Pinceladas y palabras en la paleta de imágenes de la Malinche
2007
El presente artículo se centra en el estudio de las imágenes literarias y pictóricas de una enigmática figura de la historia mexicana: la Malinche. Se intenta establecer una especie de diálogo entre las representaciones de estos dos registros, cuyas réplicas parecen completarse y, al mismo tiempo, dejar en evidencia la “no integridad” y a veces, incluso, la controversia del retrato de Malintzín. La figura de la joven india parece, más bien, un puzzle caleidoscópico de colores y palabras que se han pronunciado sobre ella. Por tanto, el objetivo de este artículo es configurar una conversación entre estas imágenes de la Malinche.
Evaluación docente vs. evaluación de la calidad
2014
Resumen basado en el de la publicación Título, resumen y palabras clave en inglés y español Artículo originalmente presentado como ponencia en el III Congreso Virtual de AIDIPE Se presenta una revisión sobre los instrumentos y dimensiones que utilizan las distintas universidades españolas para evaluar a los profesores a partir, fundamentalmente, de encuestas a los alumnos. A partir de los items que se repiten en las pruebas utilizadas en cuatro o más universidades, se ha creado un nuevo instrumento que se ha validado con 334 alumnos de la Universidad de A Coruña. A raíz de los resultados obtenidos, este instrumento podría servir tanto para la evaluación del profesorado desde la autoridad ac…

Origin of methane and light hydrocarbons in natural fluids emissions: A study from Greece.
2018
Abstract Greece, a country characterised by intense seismic and volcanic activity, has a complex geodynamic and geological setting that favours the occurrence of many gas manifestations. In this study, we address the origin of CH 4 and light hydrocarbons in cold and thermal emissions discharging along the Hellenic territory. Also, we investigate their possible relationship with the main geochemical composition of the gases and the different geological settings of the sampling sites. For this purpose we collected 101 new samples that were analysed for their chemical (O 2 , N 2 , CH 4 , CO 2 , He, Ne, Ar, H 2 , H 2 S and C 2 -C 6 hydrocarbons) and isotopic (R/R A , δ 13 C-CO 2 , δ 13 C-CH 4 a…
