Rescate folicular y regeneración del nicho ovárico mediante células madre humanas derivadas de la médula ósea
2019
El envejecimiento, la baja respuesta ovárica (PR) y otras condiciones de daño como los tratamientos oncológicos alteran la función del ovario. Sin embargo, incluso cuando los ovarios pierden su capacidad de ovular, permanecen en ellos folículos residuales durmientes que pueden ser rescatados para crecer al proporcionarles un nicho ovárico apropiado mediante distintas aproximaciones. Concretamente, se ha descrito la recuperación de la función ovárica tras el trasplante de médula ósea en pacientes con insuficiencia ovárica prematura (POI) inducida por quimioterapia. Esto sugirie un efecto positivo de las células madre de la médula ósea en el nicho ovárico. En base a ello, nos propusimos evalu…
Izmaiņas Latvijas piekrastes ainavā 20.-21. gadsimta mijā un mūsdienu izaicinājumi
2013
Dažādi faktori ietekmē piekrastes zonas attīstību gan pasaulē, gan Latvijā, kā rezultātā notiek izmaiņas ainavas struktūrā un tās spējā nodrošināt sabiedrībai nepieciešamos resursus. Promocijas darbā Latvijas piekrastes ainava ir pētīta atšķirīgos mērogos un kontekstos: i) izmaiņas jūras piekrastes ainavas struktūrā un tās ietekmējošie faktori ir vērtēti visas Latvijas piekrastes zonā; ii) potenciālā vēja enerģijas ražošanas jūrā ietekme uz ainavas vizuālo struktūru ir novērtēta unikālajā Baltijas jūras stāvkrastu zonā; iii) pludmales ainavas kā rekreācijas pakalpojuma nodrošinātāja nozīmīgums ir noskaidrots četrās atšķirīgās Latvijas pludmalēs. Darbs ir transdisciplinārs, jo tajā ir izmant…
Verb-Second and (micro)-variation in two Rhaeto-Romance varieties of Northern Italy.
2018
Rhaeto-Romance varieties are the only present-day Romance varieties which exhibit the Verb Second constraint (Benincà 1994, Poletto 2002, Salvi 2010). In this chapter we examine two properties typically ascribed to the Verb Second phenomenon, subject-finite verb inversion and restrictions on the co-occurrence of multiple constituents in the sentence-initial position, in two Rhaeto-Romance varieties spoken in South Tyrol (Province of Bolzano, Northern Italy). We demonstrate that both varieties behave like Verb-Second languages as far as both phenomena are concerned, but exhibit a specific Verb-Second system governed by the interplay between syntactic and discourse constraints which differs f…
An ultra-short measure of positive and negative affect: The Reduced Affective Well-Being Scale (RAWS).
2020
In applied organizational research, where economy of scale is often a crucial factor in successful assessment, ultra-short measures are often needed. This study investigates the psychometric properties of the Reduced Affective Well-Being Scale (RAWS), an ultra-short measure of positive and negative affect in the workplace. This 6-item ultra-short version was compared with the original 12-item scale proposed by Segura and González-Romá (2003) in terms of internal consistency and criterion validity, using a sample of 1117 bank employees. In addition, longitudinal measurement invariance and within-subject reliability of the RAWS over time were assessed in a longitudinal sample of 458 employees…

Nueva evidencia sobre la Statistical Anxiety Scale (SAS)
2014
Title: New evidence on the Statistical Anxiety Scale (SAS). Abstract: As anxiety is negatively related to academic performance, and it is broadly known the existence of both anxiety towards statistics and nega- tive statistics results, statistical anxiety may play a role of mediating negative outcomes in this subject. In this context, the Statistical Anxiety Scale (Vigil- Colet, Lorenzo-Seva, & Condon, 2008) aims to be a useful tool in the comparison of the predictive power of specific and general measures of statistics performance. In order to achieve this goal, the scale is based on three dimensions of anxiety, referred to three specific issues: regarding the exam, when asking for help or…
First insights into female sperm storage duration in tardigrades.
2022
Female sperm storage is ubiquitous in the animal kingdom and it has been shown to be linked to several evolutionary processes, from postcopulatory sexual selection to dispersal. Here we report, for the first time, long-term sperm storage in females of the tardigrade Macrobiotus polonicus. Females, isolated after a short contact with a male, were able to use the stored sperm for up to 5 weeks (mean of 2 weeks), which translates to a considerable proportion of female post-mating longevity under controlled laboratory conditions (60% on average). Our study provides the first insights into the duration of sperm storage, an underexplored feature of the reproductive biology of tardigrades. Additio…
Un "sentiero" di ricerca
2019
A research study on the ways landscape is actually communicated. Movies, advertising and partially TV are focused in order to understand the various ideas of landscape conveyed. Major studies on landscape are analized in the first part. Especially the theories of Gilles Clement on the "Third Landcape" are connected to the second part.
PROGETTARE LO SPAZIO INTERCULTURALE. Approccio multi-scalare nel quartiere Albergheria a Palermo / DESIGNING INTERCULTURAL SPACE. A multi-scalar appr…
2020
Migration has always been a major driver of urban transformation stimulating opportunities and challenges for cities and encouraging architectural and urban designers for taking a proactive and dynamic role in responding to the crisis. Enhancing these changes, and designing intercultural spaces for local communities, is a complex and urgent spatial challenge, that should be addressed by a multi-scalar approach aiming to integrate urban, architectural and public spaces. This paper illustrates a research-action resulting from a collective work developed on key urban spaces of the Albergheria neighborhood of Palermo, where a design-led research based on a multiscalar regeneration approach (urb…
Contour map of the top of the regional geothermal reservoir of Sicily (Italy).
2015
An integrated review of existing geological and geophysical data – partly acquired during oil and gas exploration – combined with new data provided by deep geothermal studies of selected key areas, was used for the 3D modeling and mapping of the top of the geothermal reservoir developed at a regional scale in Sicily (Central Mediterranean). The resulting 1:500,000 scale map covers the area of the whole Sicily (about 25,700 km2) and is devoted to represent the main input for both the thermal modeling and the evaluation of geothermal potential at a regional scale. As the map indicates the distribution at depth of a likely target for geothermal drilling, it can be also used as a rough indicato…
