BEMOD: A DSGE Model for the Spanish Economy and the Rest of the Euro Area

2006

In this paper we present the theoretical foundations and the simulation results obtained with a new dynamic general equilibrium model developed at the Banco de España for the Spanish economy and the rest of Euro area. The model is designed to help in simulating the effect of alternative shocks on the main aggregate variables. The main contributions of this work from a theoretical perspective are the modelling of a monetary union composed of two regions, the inclusion of housing as a durable good with its own sector of production and the degree and detail of the disaggregation considered for each country in the model, which replicates the Quarterly National Accounts. On the empirical side, t…

The use of very high resolution images for studying Posidonia oceanica reefs

2020

Posidonia oceanica is an endemic Mediterranean seagrass that forms wide and dense meadows from the surface up to about 40 m depth. This species can develop a biogenic structure called matte, a typical terraced formation built up by itself, consisting of intertwined rhizomes, roots and sediment, which may allow shoots to reach the sea surface forming reefs (récif barrière), considered natural monuments. Posidonia oceanica reefs are particularly exposed to the ongoing increase in temperature and in storm frequency and intensity due to climate change, with negative repercussions on their conservation. Much more attention must be paid to the implementation of monitoring tools able to detect ear…

Student engagement, truancy, and cynicism : a longitudinal study from primary school to upper secondary education

2021

Truancy in upper secondary education is a widespread problem, which contributes significantly to school dropout risk. However, the underlying mechanisms of truancy have remained unstudied. This longitudinal study of 1853 Finnish students examined how initial levels and changes in student engagement from primary (Grade 6) to lower secondary school (Grades 7 and 9) predicted truancy in upper secondary education, and whether cynicism (losing interest in school) mediated the relationship between engagement and truancy. Growth curve models showed that high engagement levels in primary school and increases in engagement over time predicted less truancy in upper secondary education. Cynicism media…

La estructura de capital en las empresas de la Comunidad Andina de Naciones (CAN) y españolas

2018

Este estudio analiza los determinantes de la estructura de capital de las empresas industriales cotizadas de los países de la Comunidad Andina de Naciones (CAN), integrados por Bolivia, Colombia, Ecuador y Perú, a lo largo del periodo 2008 a 2014. El principal objetivo que se persigue es aportar evidencia empírica en estos países desde el punto de vista de las teorías tradicionales de trade-off y pecking order, por un lado, y a partir de los enfoques más recientes de investigación que introducen el impacto de factores macroeconómicos e institucionales en los modelos de análisis, por otro. Adicionalmente, con el fin de robustecer la investigación, se realiza un análisis comparativo con una m…

Testing the Modified Sediment Delivery Model (MOSEDD) at SPA2 Experimental Basin, Sicily (Italy)

2017

A new version of a spatially distributed sediment delivery model taking into account the hillslope sediment transport efficiency, named MOSEDD, is presented. This model gives estimates of basin sediment yield at event scale, which are more reliable than those obtained by the original SEDD. For SPA2 basin discretized into morphological units, four different calculation schemes of MOSEDD, including the original SEDD version, were applied. All parameterization schemes of the model were calibrated using 15 events measured at the outlet of the experimental basin in the period February 2005–February 2010. The model calibration was used to determine a relationship between the coefficient βe of the…

Multi-Scale Modelling of Segmentation : Effect of Music Training and Experimental Task

2016

While listening to music, people, often unwittingly, break down musical pieces into constituent chunks such as verses and choruses. Music segmentation studies have suggested that some consensus regarding boundary perception exists, despite individual differences. However, neither the effects of experimental task (i.e. realtime vs annotated segmentation), nor of musicianship on boundary perception are clear. Our study assesses musicianship effects and differences between segmentation tasks. We conducted a real-time task experiment to collect segmentations by musicians and non-musicians from 9 musical pieces; in a second experiment on non-realtime segmentation, musicians indicated boundaries …

Being active in pregnancy: Theory-based factors associated with physical activity among pregnant women.

2018

ABSTRACTAlthough regular physical activity is recommended for pregnant women, compared to pre-pregnancy, antenatal physical activity often reduces or ceases completely. Drawing from the theory of planned behavior, self-determination theory, and theory on self-control, we aimed to test an integrative model of physical activity in a sample of pregnant women. The current study was conducted in Brisbane, Australia, in 2014–2015 using a prospective-correlational design with a one-week follow-up. Participants (N = 207, Time 1; Meanage = 30.03 years, SDage = 4.49 years) completed an initial survey measuring: intrinsic motivation from the self-determination theory, social cognitive constructs from …

Sense of quality of life and self-discrepancy - differences between social science and technology students

2020

The main purpose of the research is to determine personality predictors related to a new model of the sense of quality of life in a diverse group of students. The study is based on the self-discrepancy theory developed by Higgins, and the Personality and Axiological Model developed by Mróz. Method. Sixty four (64) pedagogy students and 62 electrical engineering students were the subjects of the research. The Adjective Check List test (ACL), the Modified Quality of Life Questionnaire as well as interview and observation were applied in the research. Results. Individuals with low self-discrepancy achieved significantly better results in Competences, Relationships, and Autonomy as part of the …

Recalled parental rearing style, self-esteem, and psychopathological symptoms in the general population

2020

The enduring impact of perceived parental behavior on self-esteem as well as anxiety and depression in adults is still unknown. In a large random route sample (age range 18?92), 4,747 subjects were asked to complete questionnaires about recalled parental rearing, selfesteem, anxiety, and depression. Structural equation modeling was used, and the data from the mother and the father version of the FEE (a questionnaire for recalled parental rearing) were analyzed separately. A model proposing that self-esteem mediates the relationship between parental behavior and psychopathological symptoms fits the data rather well (CFI = .95, RMSEA = .05, TLI = .94). Hence, the recalled authoritative parent…
