Surrogacy relationships: a critical interpretative review
2020
Abstract Based on a critical interpretative review of existing qualitative research investigating accounts of ‘lived experience’ of surrogates and intended parents from a relational perspective, this article proposes a typology of surrogacy arrangements. The review is based on the analysis of 39 articles, which belong to a range of different disciplines (mostly sociology, social psychology, anthropology, ethnology, and gender studies). The number of interviews in each study range from as few as seven to over one hundred. Countries covered include Australia, Canada, Greece, India, Iran, Israel, Italy, Mexico, Norway, Russia, Sweden, UK, Ukraine, and the USA. Most studies focus only on surrog…
Rotational effects on the oscillation frequencies of newly born proto-neutron stars
2003
In this paper we study the effects of rotation on the frequencies of the quasi-normal modes of a proto-neutron star (PNS) born in a gravitational collapse during the first minute of life. Our analysis starts a few tenths of seconds after the PNS formation, when the stellar evolution can be described by a sequence of equilibrium configurations. We use the evolutionary models developed by Pons et al. (1999; 2001) that describe how a non rotating star cools down and contracts while neutrino diffusion and thermalization processes dominate the stellar dynamics. For assigned values of the evolution time, we set the star into slow rotation and integrate the equations of stellar perturbations in th…
Kernel Feature Extraction Methods for Remote Sensing Data Analysis
2014
Technological advances in the last decades have improved our capabilities of collecting and storing high data volumes. However, this makes that in some fields, such as remote sensing several problems are generated in the data processing due to the peculiar characteristics of their data. High data volume, high dimensionality, heterogeneity and their nonlinearity, make that the analysis and extraction of relevant information from these images could be a bottleneck for many real applications. The research applying image processing and machine learning techniques along with feature extraction, allows the reduction of the data dimensionality while keeps the maximum information. Therefore, develo…

Assessment itineraries and its relation with academic achievement
2017
[EN] In recent years the university educational reality shows signs of change. Among other innovations, it has meant the introduction of new ways of assessment, arousing the scientific interest it deserves. Concretely, the formative and shared assessment is developed in assessment routes that try to adapt to the needs of the students. However, the continuous, mixed and final assessment methods are related to different academic performance, which is worth considering. This article tries to deepen in the relation that these itineraries have with the obtained marks and analyses descriptively teacher assessment trends and students’ system assessment preferences of choice. The results show, on t…

Choroidal thickness in glaucoma patients and glaucoma suspects measured by spectral domain coherence optical tomography
2012
Purpose: The aim of our study was to evaluate and compare retro-foveolar choroidal thickness (RFCT) of healthy subjects, individuals with intraocular hypertension, patients with primary open-angle glaucoma (POAG), patients with normal tension glaucoma (NTG) and patients with primary angle-closure glaucoma (PACG) by spectral domain optical coherence tomography (SD-OCT).Methods: Sixty-five healthy eyes, 30 eyes with intraocular hypertension, 90 eyes with POAG, 30 eyes with NTG and 20 eyes with PACG were included in this cross-sectional study. RFCT, foveolar retinal thickness and average retinal nerve fiber layer thickness (RNFL) were measured by SD-OCT (Spectralis HRA-OCT, Heidelberg Engineer…
Quality culture boosts agile transformation : Action research in a business‐to‐business software business
2023
Agile methodologies are sometimes adopted, with the assumption that benefits can be attained by only using a set of best practices, which can sometimes work to a degree. In this paper, a case is discussed where a software-producing organization of seven teams achieved significant improvements. The goal of the research was to answer two questions: how an already agile organization could improve its performance further and what is the impact of promoting quality aspects? The questions were answered by implementing interventions based on prior literature and data emerging from semi-structured interviews. The context was an established business with a complex revenue stream structure, meaning t…
