Nación, emoción y fantasía. La España melodramática de Ayguals de Izco = Nation, Emotion and Fantasy. Ayguals de Izco's Melodramatic Spain
2017
El artículo analiza las novelas por entregas de Wenceslao Ayguals de Izco (1801-1873) desde su dimensión melodramática para señalas de qué modo participaron en la creación de los imaginarios, las narrativas sociales y políticas y la "comunidad emocional" del radicalismo democrático español de mediados del siglo XIX. Posteriormente examino una serie de "fantasías nacionales" que se repiten con insistencia en estas novelas melodramáticas: la unión matrimonial como metáfora de la plenitud nacional, el mártir por la patria y el "ángel de salvación" que socorre a los desfavorecidos. Todas estas fantasías se fundan en la diferencia sexual (al tiempo que la construyen) y permiten la identificación…
The Rhetoric and Relevance of IS Research Paradigms: Conceptual Foundations and Empirical Evidence
2006
This paper discusses the relevance of IS research with respect to the rhetoric associated with the three major IS research paradigms in use - positivism, constructivism/interpretivism and critical research. The conceptual discussion is framed in terms of the following dimensions: ontological, epistemological and methodological assumptions, relationship between theory and practice, and the role of the researcher in the research process. Based on this discussion, we propose a conceptual model to study the relationship between the espoused philosophical assumptions of researchers and the degree of relevance of researchers’ knowledge claims. This conceptual model was evaluated with data obtaine…

THE MATHEMATICAL MODELING OF METALS CONTENT IN PEAT
2015
Metals deposition in peat can aid to evaluate impact of atmospheric or wastewaters pollution and thus can be a good indicator of recent and historical changes in the pollution loading. For peat using in agriculture, industrial, heat production etc. knowledge of peat metals content is important. Experimental determination of metals in peat is very long and expensive work. Using experimental data the mathematical model for calculation of concentrations of metals in different points for different layers is developed. The values of the metals (Ca, Mg, Fe, Sr, Cu, Zn, Mn, Pb, Cr, Ni, Se, Co, Cd, V, Mo) concentrations in different layers in peat taken from Knavu peat bog from four sites are deter…
Similarities and Differences of Mental Health in Women and Men: A Systematic Review of Findings in Three Large German Cohorts
2021
In Germany, large, population-based cohort studies have been implemented in order to identify risk and protective factors for maintaining health across the life span. The purpose of this systematic review is to analyse findings from three large ongoing cohorts and to identify sex-specific prevalence rates, risk and protective factors for mental health. Published studies from the Cooperative Health Research in the Region Augsburg (KORA), the Study of Health in Pomerania (SHIP) and the Gutenberg Health Study (GHS)), representing the southern, north-eastern and middle parts of Germany, were identified through searches of the databases PubMed and Web of Science. A total of 52 articles was ident…
The Impact of COVID-19 Pandemic and Lockdown Measures on Quality of Life among Italian General Population
2021
The COVID-19 pandemic that has hit the world in the year 2020 has put a strain on our ability to cope with events and revolutionized our daily habits. On 9 March, Italy was forced to lockdown to prevent the spread of the infection, with measures including the mandatory closure of schools and nonessential activities, travel restrictions, and the obligation to spend entire weeks in the same physical space. The aim of this study was to assess the impact of the COVID-19 pandemic and lockdown measures on quality of life (QoL) in a large Italian sample, in order to investigate possible differences in QoL levels related to both demographic and pandemic-specific variables. A total of 2251 Italian a…
Prevalence of maxillary canine impaction in skeletal Class III malocclusions compared to Class I malocclusions
2019
Background The aim of the present investigation was to evaluate if an orthodontic population of Class III malocclusion patients shows a different prevalence of maxillary canine impaction than Class I subjects. Material and methods Fifty-eight subjects were retrospectively selected and assigned to the Class I group (n= 32) or the Class III group (n= 26), depending on the ANB and WITS values. Lateral cephalograms were used to collect angular and linear measurements that described the skeletal and dental maxillary features of the subjects, while orthopantomography was used to assess the impaction or the correct eruption of the maxillary canines. An independent samples T-test or a Mann-Whitney …
Blood absorption capacity of different xenograft bone substitutes. An in-vitro study
2019
Background Commercially available xenograft blocks, claim to have adequate characteristics to interact with biological media and thus permitting biological fluid absorption. The objective of this in vitro study was to compare the blood absorption capacity of four different xenograft block materials of different composition of collagen and porosity. Material and Methods Four brands of xenograft block materials were used (NuOss®, Bio-Oss®, Osteobiol® and Smartbone®). Five samples of each brand were analyzed, making a total of 20 tests. Human blood was used as the absorption liquid for the present experiment. The time period, in which the block remains in contact with the blood, was registered…
Positive solutions of discrete boundary value problems with the (p,q)-Laplacian operator
2017
We consider a discrete Dirichlet boundary value problem of equations with the (p,q)-Laplacian operator in the principal part and prove the existence of at least two positive solutions. The assumptions on the reaction term ensure that the Euler-Lagrange functional, corresponding to the problem, satisfies an abstract two critical points result.
Public Health Genomics education in post-graduate schools of hygiene and preventive medicine: a cross-sectional survey.
2014
Background The relevance of Public Health Genomics (PHG) education among public health specialists has been recently acknowledged by the Association of Schools of Public Health in the European Region. The aim of this cross-sectional survey was to assess the prevalence of post-graduate public health schools for medical doctors which offer PHG training in Italy. Methods The directors of the 33 Italian public health schools were interviewed for the presence of a PHG course in place. We stratified by geographical area (North, Centre and South) of the schools. We performed comparisons of categorical data using the chi-squared test. Results The response rate was 73% (24/33 schools). Among respond…
