Testing Sediment Connectivity at the Experimental SPA2 Basin, Sicily (Italy)
2017
The concept of sediment delivery can be used as a measure of sediment connectivity, and it can be linked to the structural connectivity (morphological unit, slope length, slope steepness, travel time) of a basin and to the hydrological connectivity (rainfall–runoff processes at morphological unit scale). In this paper, the sediment connectivity concept was tested at basin scale applying SEdiment Delivery Distributed model, which takes into account the hillslope sediment transport, and using sediment yield measurements carried out at SPA2 experimental basin (Sicily, Italy). For the SPA2 basin discretized into morphological units, the SEdiment Delivery Distributed model was first calibrated a…
Short-Term Vegetation Recovery after a Grassland Fire in Lithuania: The Effects of Fire Severity, Slope Position and Aspect
2016
In Lithuania, fire is frequently used by farmers as a tool to remove dry grass, improve soil nutrient status and help soil tilling. However, little is known about the ecological impacts of these fires, including vegetation recovery. The objective of this work is to study the impacts of a spring grassland fire on vegetation recuperation on an east-facing (A) and a west-facing slope (B), considering fire severity and slope position, 10, 17, 31 and 46 days after the fire. Because of their effects on fire behaviour, aspect, steepness and heterogeneity of topography favoured higher fire severity on slope B than on slope A. Three different slope positions were identified on slope A – flat top, mi…
Does EU cohesion policy work? Theory and evidence
2017
This paper evaluates the effectiveness of European Cohesion Policy in the regions of 12 EU countries in the period 1991–2008, on the basis of a spatial growth model, which allows for the identification of both direct and indirect effects of EU funds on GDP per worker growth. We find that “Objective 1” funds are characterized by strong spatial externalities and a positive and concave effect on the growth of GDP per worker, which reaches a peak at the ratio funds/GDP of approximately 3 percent and becomes non-significant after 4 percent. “Objective 2” and “Cohesion” funds have nonsignificant effects, while all the other funds exert a positive and significant effect, but their size is very lim…
Data on the effects of low iron diet on serum lipid profile in HCV transgenic mouse model
2017
Here, we presented new original data on the effects of iron depletion on the circulating lipid profile in B6HCV mice, a murine model of HCV-related dyslipidemia. Male adult B6HCV mice were subjected to non-invasive iron depletion by low iron diet. Serum iron concentration was assessed for evaluating the effects of the dietary iron depletion. Concentrations of circulating triglycerides, total cholesterol, Low Density Lipoproteins (LDLs), High Density Lipoproteins (HDLs) were analyzed and reported by using stacked line charts. The present data indicated that low serum iron concentration is associated to i) lower serum triglycerides concentrations and ii) increased circulating LDLs. The presen…
Gender gap in Swiss vocational education and training teachers’ economics content knowledge and the role of teaching experience
2019
In the commercial sector, which is of crucial importance to the Swiss economy among other countries, a large number of apprentices are trained on a vocational education and training programme every year. Besides other subjects, the subject Economics and Society forms an integral part of the vocational education and training curriculum and serves to prepare apprentices for professional, economic and civic participation. Although content knowledge is widely considered necessary to both teaching quality and student achievement, little is known about the subject-specific content knowledge of Swiss Economics and Society teachers. As previous research has shown a gender gap in the content knowled…
Cognitive mechanisms underlying reading and spelling development in five European orthographies
2014
This paper addresses the question whether the cognitive underpinnings of reading and spelling are universal or language/orthography-specific. We analyzed concurrent predictions of phonological processing (awareness and memory) and rapid automatized naming (RAN) for literacy development in a

Multisensory texture exploration at the tip of the pen
2016
A tool for the multisensory stylus-based exploration of virtual textures was used to investigate how different feedback modalities (static or dynamically deformed images, vibration, sound) affect exploratory gestures. To this end, we ran an experiment where participants had to steer a path with the stylus through a curved corridor on the surface of a graphic tablet/display, and we measured steering time, dispersion of trajectories, and applied force. Despite the variety of subjective impressions elicited by the different feedback conditions, we found that only nonvisual feedback induced significant variations in trajectories and an increase in movement time. In a post-experiment, using a pa…
