Molecular Alterations in Spermatozoa of a Family Case Living in the Land of Fires. A First Look at Possible Transgenerational Effects of Pollutants.
2020
In our previous work, we reported alterations in protamines/histones ratio, in DNA binding of these proteins and their involvement in DNA oxidative damage in 84% of the young men living in the Land of Fires. In the present work, we extended our findings, evaluating any alterations in spermatozoa of a family case, a father and son, living in this area, to also give a first look at the possibility of transgenerational inherited effects of environmental contaminants on the molecular alterations of sperm nuclear basic proteins (SNBP), DNA and semen parameters. In the father and son, we found a diverse excess of copper and chromium in the semen, different alterations in SNBP content and low DNA …
Análisis de la producción científica de las revistas españolas de ciencias de la salud indizadas en los Jornal Citation Reports (2003-2007)
2010
El enorme desarrollo y las dimensiones que ha cobrado la Ciencia moderna exige la evaluación de los resultados de la actividad investigadora y de los actores que intervienen en este proceso, evaluación que resulta fundamental para los propios investigadores, organismos gestores de las políticas científicas, editores y organizaciones implicadas en la generación y difusión del conocimiento científico. La tesis doctoral analiza las investigaciones difundidas en las principales revistas biomédicas editadas en España a lo largo del período 2003-2007, integrando las aportaciones de la Bibliometría para caracterizar la productividad, colaboración e impacto de los trabajos; el aporte del Análisis d…
Les drogodependències, una visió actualitzada
2013
Public opinion is not worried about drug dependence and other addictive disorders anymore. The changes in consumption patterns and the lack of visible situations related to drugs consumption have removed this problem from the top of the media’s agenda; however, we are able to establish that this is not a settled problem from the past, but quite the opposite. Despite all the prevention campaigns launched so far, the drugs consumption phenomenon prevails as well as the increase of the number of admissions in detoxification clinics for drug addicts. Therefore, it would be necessary to make a review of the history of drug dependence in order to find the key of the causes thereof nowadays, putti…
ProcessWiki: A Contribution for Bridging the Last Mile Problem in Automotive Retail
2012
In many real-world business process management (BPM) installments, the benefit of BPM is diminished by an insufficient implementation of the to-be business processes. One of the key reasons for this problem is the complexity of classical process modeling representations that exceed the BPM knowledge of many target groups.
Handling Evolving Data Warehouse Requirements
2015
A data warehouse is a dynamic environment and its business requirements tend to evolve over time, therefore, it is necessary not only to handle changes in data warehouse data, but also to adjust a data warehouse schema in accordance with changes in requirements. In this paper, we propose an approach to propagate modified data warehouse requirements in data warehouse schemata. The approach supports versions of data warehouse schemata and employs the requirements formalization metamodel and multiversion data warehouse metamodel to identify necessary changes in a data warehouse.
Dietas confinadas: análisis del discurso de la prensa sobre la nutrición en tiempos de Covid-19
2021
The essential elements of the Spanish press’s discourse on nutrition guidelines during the Covid-19 health crisis are identified. To do this, the evolution of media representation is examined, with a semantic analysis of the news appearing in the national media in Spanish regarding nutrition and Covid-19. The analyzed period is from 31 January 2020 to 31 January 2021. The content search carried out using the Factiva database identified 117 records, which were analysed using T-LAB software. The results reveal that the press warned of hoaxes regarding nutrition during the study period. Four semantic groups are identified, informing about the most appropriate eating patterns according to the d…
Revenue models, in-app purchase, and the app performance: Evidence from Apple's App Store and Google Play
2016
The effect of revenue models on app performance depends on the app store.The effect of in-app purchase on app performance depends on the app store.Paid, freemium and in-purchase models are shown to be effective in app store.Freemium and in-app purchase models are shown to be less effective in Google Play.App category influences the effects of both revenue models and in-app purchase. In this paper, we empirically examine how the revenue model (paid, free, or freemium) adopted for a given app affects the app revenue performance as measured by the app daily revenue rank. We also study the impact of in-app purchase on this measure of performance. Moreover, we study how such relationships are co…
TOURISM MARKETING - KEY CONCEPT OF TOURISM IN A WORLD OF GLOBALIZATION
2012
The latest trends in tourism emphasize the power of the globalized tourist-consumer, in the context of mondialisation of the market and of the diversity of tourism services, the tourism organizations must answer to a range of different tourism motivations meant to meet the needs and wishes of the tourism consumers over the period they travel for.

Performing transnational family with the affordances of mobile apps : a case study of Polish mothers living in Finland
2020
Affordances provided by digital technologies and mobile apps (WhatsApp, Skype, Messenger) help in maintaining familyhood. These mobile apps enable the creation of in-app family groups. They also afford image sharing, which is used for phatic purposes. Digital connectivity provides the illusions of togetherness and belonging, and allows for performing family in a transnational context (emotional transnationalism). However, it also generates the feelings of guilt through infrequent communication. In the auto-driven visual elicitation interviews, the study looks at family constellations and technologically mediated communication from the perspective of five Polish mothers living in Finland. Ap…
