Molecular phylogeny of the genus Chondrina (Gastropoda, Panpulmonata, Chondrinidae) in the Iberian Peninsula
2022
[EN] Chondrina Reichenbach, 1828 is a highly diverse genus of terrestrial molluscs currently including 44 species with about 28 subspecific taxa. It is distributed through North Africa, central and southern Europe, from Portugal in the West to the Caucasus and Asia Minor in the East. Approximately 70% of the species are endemic to the Iberian Peninsula constituting its main center of speciation with 34 species. This genus includes many micro endemic taxa, some of them not yet described, confined to limestone habitats (being strictly rock-dwelling species). They are distributed on rocky outcrops up to 2000 m.a.s.l. It is a genus of conical-fusiform snails that differ mainly in shell characte…
Species size affects hatching response to different temperature regimes in a rotifer cryptic species complex
2013
The strategy of decreasing size with increasing temperature known as Bergmann’s rule operates at geographic scale and in spite of extensive studies still presents a puzzle to researches. The aim of this work was to verify whether patterns of diapausing egg hatching of closely related species are consistent with the expectations from Bergmann’s rule. In a laboratory study of the cryptic species complex of the rotifer Brachionus plicatilis, the response to temperature (17.5, 22.5, and 25.0 °C) of diapausing eggs collected in a pond where the three tested species coexist was assessed by (1) the number of hatchlings emerging or (2) the time needed to hatch. Our results show that the response to…
Misunderstanding Situations in Culture and Cultural Care
2017
This article focuses on cultural misunderstanding in care relations, starting from the analysis of the effects misunderstanding causes in the relation between doctor and migrant patient. The Western medical model tends to be based on objective data, which can be diagnosed through more and more precise and detailed techniques, but it excludes human and cultural aspects of subjectivity and relation from care. This exclusion creates distance, which increases when doctor and patient do not share a cultural homogeneity but differ for their language and the way they conceive their body, health, and disease. By showing some clinical examples, this contribution points out how specialized competence…
Differential constraints for iteratively generated curves
2021
Roughness is a complex concept, that is multiscale, and based on the study of the local behavior of a curve or a surface in a given neighborhood. A large number of conventional statistical parameters are currently available to attempt to appreciate this concept in the different application areas that make use of it. But it is often difficult, for a given application domain or a special need, to know precisely which parameter(s) connect(s) the topography of a surface to the physical phenomena that it undergoes. We believe that a geometric characterization should be more suitable. We suggest to control roughness by exploiting the differential behavior of curves and surfaces. We are interested…
Species–area relationships in continuous vegetation: Evidence from Palaearctic grasslands
2019
Aim Species-area relationships (SARs) are fundamental scaling laws in ecology although their shape is still disputed. At larger areas, power laws best represent SARs. Yet, it remains unclear whether SARs follow other shapes at finer spatial grains in continuous vegetation. We asked which function describes SARs best at small grains and explored how sampling methodology or the environment influence SAR shape. Location Palaearctic grasslands and other non-forested habitats. Taxa Vascular plants, bryophytes and lichens. Methods We used the GrassPlot database, containing standardized vegetation-plot data from vascular plants, bryophytes and lichens spanning a wide range of grassland types throu…
The Role of 3D-Printed Custom-Made Vertebral Body Implants in the Treatment of Spinal Tumors: A Systematic Review
2022
In spinal surgery, 3D prothesis represents a useful instrument for spinal reconstruction after the removal of spinal tumors that require an “en bloc” resection. This represents a complex and demanding procedure, aiming to restore spinal length, alignment and weight-bearing capacity and to provide immediate stability. Thus, in this systematic review the authors searched the literature to investigate and discuss the advantages and limitations of using 3D-printed custom-made vertebral bodies in the treatment of spinal tumors. A systematic literature review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement, with no limits in terms …
Characterizing Web sessions of e-customers interested in traditional and innovative products
2016
Web traffic characterization and modelling is currently a hot research issue. Low-level analysis of HTTP traffic on the server allows one to build adequate traffic models to be used in server benchmarking. High-level analysis of Web user behavior allows one to optimize website structure and develop personalized service strategies. In this paper, analysis of customer sessions in an online store is performed using Web server log data. The goal is to explore possible differences between sessions of customers viewing and purchasing innovative products, and customers only interested in traditional products.
Importance of Strategic Social Media Marketing
2017
Technological innovation has grown at an unprecedented rate over the past couple of decades, creating multiple opportunities for marketing in online settings. The proliferation of social media helps customers become more empowered and engaged in their brand interactions, while also providing them with new tools in their search, evaluation, choice and purchases of marketing offerings. Consequently, these developments are influencing marketing practices, both strategically, and tactically. Nowadays, social media has developed in an essential part of marketing strategy for its ability to generate co-created value, to interactively connect brands to consumers, to monitor brand-related discussio…
Developing and Validating a Behavioural Model of Cyberinsurance Adoption
2021
Business disruption from cyberattacks is a growing concern, yet cyberinsurance uptake remains low. Using an online behavioural economics experiment with 4800 participants across four EU countries, this study tests a predictive model of cyberinsurance adoption, incorporating elements of Protection Motivation Theory (PMT) and the Theory of Planned Behaviour (TPB) as well as factors in relation to risk propensity and price. During the experiment, participants were given the opportunity to purchase different cybersecurity measures and cyberinsurance products before performing an online task. Participants likelihood of suffering a cyberattack was dependent upon their adoption of cybersecurity me…
Cybersex in the “Net generation”: Online sexual activities among Spanish adolescents
2016
The internet offers several opportunities to explore sexuality among adolescents. However, some studies have also revealed problematic effects of cybersex in earlier stages. Despite this, few studies analyze the online sexual behavior among adolescents, even less in Spain where there is very little data. For this reason, our aim is to examine the use of internet for sexual purposes among Spanish adolescents, including gender differences. Three hundred and twenty-two adolescents completed an ad-hoc questionnaire and the Spanish version of the Internet Sex Screening Test. In general, boys report more cybersex than girls do, for example, in masturbating while the Internet (60.6% of boys and 7.…
