Factores asociados al estrés prenatal y la ansiedad en gestantes durante el COVID-19 en España
2022
AIM OF THE STUDY To describe prenatal stress and state anxiety levels in pregnant women living in Spain during the lockdown of the first wave of COVID-19 and its relation with obstetric factors, perception of health care, and concerns about the socio-sanitary situation. METHODS The present study is an observational, correlational, and cross-sectional quantitative study. The participants in the study were pregnant women recruited through non-probabilistic convenience and snowball sampling during the lockdown. A web link was provided to an online questionnaire designed for this research, which collected socio-demographic and obstetric variables, perceptions of health care received during the …
RDF-Based Web Information Integration System: A Travel System Use Case
2018
Enterprises are continually faced with the challenge of integrating heterogeneous systems with incompatible interfaces, data structures (Source structured relational databases, semi-structured sources, XML, or unstructured documents: texts), access mode and technologies. When companies adopt SOA (Service Oriented Architecture), that provides an alternative to traditional design of applications by allowing a designer to assemble and compose existing services that implement the functions of a given application domain, they realize that there is a significant risk that Web services only do not solve the problem of compatibility in the data. Our paper gives a solution to these issues by setting…
Integration of distributed healthcare records: publishing legacy data as XML documents compliant with CEN/TC251 ENV13606
2003
To support co-operative work among health professionals and institutions it is necessary to share healthcare information about patients in a meaningful way. But, nowadays, in most hospitals health data are distributed across several information systems whose interconnection is difficult to achieve, this leads to the so-called islands of information. This paper briefly describes the architecture, design and implementation of the PANGEA system. PANGEA allows healthcare professionals to access patient information stored in heterogeneous autonomous information systems through a set of formal aggregates of health data based on the European pre-standard of Healthcare Record Architecture ENV13606 …
Revenue models in cloud computing
2012
Cloud computing brings new possibilities, allowing software firms to sell their software products using the Software-as-a-Service (SaaS) model. SaaS provides opportunities for flexible pricing but creates challenges on how to achieve a profitable revenue stream. In this multicase study, the revenue models of five SaaS providers were examined. The main interest of the study was to investigate the different revenue models and the reasons for using particular revenue models. The revenue models were found to be mainly based on software renting, with a variety of pricing strategies. For SaaS providers, software renting generates a steady and predictable stream of revenue. The software renting mo…
How Can Secure Websites Improve Buying Intention?
2014
A conceptual model is proposed to show 3 effects of augmenting security perceptions (more pleasure, less perceived risk and higher trust) in order to improve buying intention. The role of usability in reinforcing these direct and indirect security effects has also been tested. This study examines the reinforcement of previous relationships in highly usable contexts. To test this, a fictitious website was designed for a nonexistent clothing company directed at the segment of middle class consumers. Two blocks of changes were made to alter website usability: one concerning website speed and the other related to ease of use. Results for a study sample of 170 respondents show that in usable con…
Proactive Future Internet: Smart Semantic Middleware for Overlay Architecture
2009
Some initiatives towards Future Internet, e.g., GENI, DARPA's Active Networks, argue the need for programmability of the network components. Some other initiatives extend this with argumentation for declarative networking, where the behavior of a network component is specified using some high-level declarative language, with a software-based engine implementing the behavior based on that specification. Our Proactive Future Internet (PROFI) vision follows these initiatives targeting also the following two problems: interoperability of the network elements programmed by different organizations, and the need for flexible cooperation among network elements, including coordination, conflict reso…
Key drivers of consumer loyalty to Facebook fan pages
2014
Purpose – With the rapid expansion of social networking sites, researchers and practitioners are challenged to understand drivers of customer loyalty in fan pages.

Design/methodology/approach – The impact of trust, fan page content dependency, attitude and consumer beliefs on loyalty to fan pages was tested through structural equation modelling techniques. The sample consisted of 691 Spanish Facebook users. Findings – Data analysis shows that attitude appears as a key variable in increasing loyalty to fan pages. T…
Blogs ciudadanos en las elecciones españolas de 2008: asimilación de la agenda y reproducción de la lógica partidista
2012
El presente estudio se propone dilucidar las características de la blogosfera política española durante la campaña de 2008 mediante una muestra de tres reputados blogs ciudadanos y esclarecer si se produce una discusión ciudadana independiente de la agenda partidista y mediática. El análisis de contenido permitirá identificar el tipo de cobertura que estos blogs realizan sobre la campaña a través de las siguientes variables: enlaces, temas principales, protagonistas y valoraciones de los autores. Las conclusiones sugieren una significativa fragmentación de la blogosfera en espacios ideológicos, carentes de conexión entre sí y tendentes a la polarización del discurso. The present study inten…
Exploring User Behavior in Destination Websites: An Application of Web Mining Techniques
2021
The development of the Internet has so strongly affected the way a tourist destination can be promoted that portals now play an important role in defining the marketing strategies of tourist destinations. Hence, investigating website surfing behavior has become crucial to understanding the needs of potential tourists. Using Web Mining techniques, our study explores the information-seeking behavior of those who log on to a website promoting the island of Sicily, a well known tourist destination in the South of Italy. The study explores whether a tourist’s country of origin affects their information needs and surfing behavior. Actually, our results do show differences in behavior between user…
A REST-based publish/subscribe platform to support things-to-services communications
2013
The term “Internet of Things” has been used widely in recent years, bringing up a grand idea of connecting physical objects with one another through both wired and wireless networks. Maturity of the Internet Protocol has pushed 21st century communications between devices to go all-IP, which includes everyday objects. Many new services are deployed in the “cloud”, utilising the Internet infrastructure and the Web, and information from everyday objects can play an important role. This paper presents an information integration platform which enables everyday objects to communicate with Internet services based on event-driven service-oriented architecture paradigm. A proof-of-concept prototype …
