Changes in the proteome of sea urchin Paracentrotus lividus coelomocytes in response to LPS injection into the body cavity.
2020
Background The immune system of echinoderm sea urchins is characterised by a high degree of complexity that is not completely understood. The Mediterranean sea urchin Paracentrotus lividus coelomocytes mediate immune responses through phagocytosis, encapsulation of non-self particles, and production of diffusible factors including antimicrobial molecules. Details of these processes, and molecular pathways driving these mechanisms, are still to be fully elucidated. Principal findings In the present study we treated the sea urchin P. lividus with the bacterial lipopolysaccharide (LPS) and collected coelomocytes at different time-points (1, 3, 6 and 24 hours). We have shown, using label-free q…
The interplay between emotion regulation, interpersonal problems and eating symptoms in individuals with obesity: A network analysis study
2023
Introduction: A complex and bidirectional relationship between eating and psychological symptoms in individuals with obesity has been proposed. This study aims to identify the specific processes playing a role in this association, using a data-driven approach. Methods: Two hundred ninety-four adults with obesity, including 106 (36 %) with binge-eating disorder, were consecutively admitted to a specialized public center. They completed self-report questionnaires to assess emotion regulation, interpersonal problems, self-esteem, binge-eating symptoms, and expectancies regarding eating behaviors. To assess the interplay among eating and psychological variables, a network analysis was used. The…
Psychological Network Analysis of General Self-Efficacy in High vs. Low Resilient Functioning Healthy Adults
2021
Resilience to stress has gained increasing interest by researchers from the field of mental health and illness and some recent studies have investigated resilience from a network perspective. General self-efficacy constitutes an important resilience factor. High levels of self-efficacy have shown to promote resilience by serving as a stress buffer. However, little is known about the role of network connectivity of self-efficacy in the context of stress resilience. The present study aims at filling this gap by using psychological network analysis to study self-efficacy and resilience. Based on individual resilient functioning scores, we divided a sample of 875 mentally healthy adults into a …
Effective 1-day ahead prediction of hourly surface ozone concentrations in eastern Spain using linear models and neural networks
2002
The aim of this research was to develop pure predictive models in order to provide 24 h advance forecasts of the hourly ozone concentration for the rural site of Carcagente (Valencia, Spain) and the urban sites of Paterna (Valencia, Spain) and Alcoy (Alicante, Spain) over 4 years from 1996 to 1999. The peculiarity of the model presented here is that it uses past and previously predicted information of inputs exclusively, thus being this is the first genuine 24 h advance O3 predictive model with neural networks. We used autoregressive-moving average with exogenous inputs (ARMAX), multilayer perceptrons and FIR neural networks. Five performance measures yield reasonably good results in the th…
Utility of social networks and online data collection in nursing research: Analysis of Spanish nurses’ level of knowledge about palliative care
2018
Introduction Internet-based social networks are used by nurses with different purposes, including the creation of working groups and to share and create knowledge. Purpose To evaluate the utility of social networks in the dissemination of an online questionnaire and to measure Spanish RNs’ knowledge about palliative care. Methods A descriptive cross-sectional study was carried out. Using social networks we distributed an online questionnaire with the Spanish version of Palliative Care Quiz for Nurses (PCQN-SV) throughout August 2015. Results A direct relationship between the number of responses and the questionnaire’s apparitions in each social network was found. Comparing the results obtai…
A prospective study on an innovative online forum for peer reviewing of surgical science
2017
Background Peer review is important to the scientific process. However, the present system has been criticised and accused of bias, lack of transparency, failure to detect significant breakthrough and error. At the British Journal of Surgery (BJS), after surveying authors' and reviewers' opinions on peer review, we piloted an open online forum with the aim of improving the peer review process. Methods In December 2014, a web-based survey assessing attitudes towards open online review was sent to reviewers with a BJS account in Scholar One. From April to June 2015, authors were invited to allow their manuscripts to undergo online peer review in addition to the standard peer review process. T…
ESCR Review: Citizenship and Politics
2020
This chapter describes the analyses and results for the ESRC Domain of Citizenship and Politics, guided by two main questions: How digital technology impacts on our autonomy, agency, and privacy; Whether and how our understanding of citizenship is evolving in the digital age. It first provides an initial overview of the major insights from the literature review and analysis, the Delphi surveys, and workshop discussions about the relevant range of the concepts of citizenship and politics in a digital age. Over time the literature shows a shift from issues of public sphere and use of the Internet by government and candidates to more focus on political participation and engagement, especially …

A Study of the Bibliometry and Areas of the Research Groups of Archivos de Bronconeumología (2003–2007)
2010
Introduction Scientific cooperation is essential for the advance of biomedical research. Scientists set up informal groups to work together on common issues, who are the main units in the research funding system. Bibliometric and Social Network Analysis methods allow informal groups in scientific papers to be identified and characterised. The objective of the study is to identify research groups in Archivos de Bronconeumologia between 2003 and 2007 period with the aim of characterizing their scientific collaboration patterns and research areas.
Reti mafiose. Cosa nostra e camorra: organizzazioni criminali a confronto
2011
Nella vastissima produzione editoriale sul fenomeno mafioso i gruppi criminali sono stati spesso rappresentati come organizzazioni verticistiche, fortemente centralizzate e gerarchizzate. Si è fatto spesso ricorso alla metafora della piramide, della burocrazia o dell'azienda, evidenziando, in tal modo, la presenza di una netta articolazione interna e di una precisa suddivisione dei ruoli e delle funzioni tra i singoli associati. Pur riconoscendo l'efficacia e la persistente attualità di una simile rappresentazione, questo volume guarda alle organizzazioni criminali da un punto di vista differente, adoperando una prospettiva di analisi di tipo relazionale. Le singole cosche possono essere, i…
