The role of regional competitiveness in shaping the heterogeneous impact of the Great Recession
2020
This paper assesses the employment resilience of 202 European regions to the Great Recession by investigating the role of regional competitiveness. By using the regional shift component derived from a multiple bases shift–share analysis of employment change as a measure of regional endogenous employment growth, we show that pre‐crisis regional competitiveness determinants are associated with positive performances during the crisis period. However, the variables considered explain well the different vulnerability of the economies, but less convincingly the ability to recover. Taking into account the spatial interactions among regions, results are confirmed and allow us to identify spillover …
Predicted gamma-ray image of SN 1006 due to inverse Compton emission
2009
We propose a method to synthesize the inverse Compton (IC) gamma-ray image of a supernova remnant starting from the radio (or hard X-ray) map and using results of the spatially resolved X-ray spectral analysis. The method is successfully applied to SN 1006. We found that synthesized IC gamma-ray images of SN 1006 show morphology in nice agreement with that reported by the H.E.S.S. collaboration. The good correlation found between the observed very-high energy gamma-ray and X-ray/radio appearance can be considered as an evidence that the gamma-ray emission of SN 1006 observed by H.E.S.S. is leptonic in origin, though the hadronic origin may not be excluded.
Partycypacja społeczna w kontekście budowy trasy średnicowej w Opolu
2019
Autor artykułu postawił sobie za cel opisanie przebiegu konfliktu przestrzennego oraz analizę procesu partycypacji społecznej w kontekście planowanej budowy trasy średnicowej przebiegającej przez wyspę Pasiekę w Opolu. Posługując się metodą studium przypadku podjęto próbę znalezienia odpowiedzi na pytania: czy władze samorządowe zastosowały „dobre praktyki” postulowane przez organizacje pozarządowe oraz jaką rolę odegrał w nich ruch miejski.
Self-reported life-space mobility in the first year after ischemic stroke: longitudinal findings from the MOBITEC-Stroke project
2023
Abstract Background Life-space mobility is defined as the size of the area in which a person moves about within a specified period of time. Our study aimed to characterize life-space mobility, identify factors associated with its course, and detect typical trajectories in the first year after ischemic stroke. Methods MOBITEC-Stroke (ISRCTN85999967; 13/08/2020) was a cohort study with assessments performed 3, 6, 9 and 12 months after stroke onset. We applied linear mixed effects models (LMMs) with life-space mobility (Life-Space Assessment; LSA) as outcome and time point, sex, age, pre-stroke mobility limitation, stroke severity (National Institutes of Health Stroke Scale; NIHSS), modified R…
Social participation in shaping their local landscape
2015
Charakter lokalnego krajobrazu w znaczącej części zależy od poziomu świadomości społeczności, która na danym terenie egzystuje. Głównie chodzi tutaj o poczucie własnej wartości kulturowej oraz znajomości chociażby podstawowych zasad ekologicznego korzystania z zasobów krajobrazowych. Głównym celem badań, których wyniki przedstawiono w niniejszym rozdziale było uzyskanie odpowiedzi na ile i w jakim zakresie ankietowani uważają, że mają znaczący wpływ na podejmowane decyzje w dziedzinie szeroko pojętego modelowania otaczającego ich krajobrazu? Stwierdzenie „Myśl globalnie – działaj lokalnie” czy też „Gmina terenem racjonalnego kształtowania krajobrazu” – jak potwierdzają wyniki przeprowadzony…

Spatial distribution of soil water repellency in a grassland located in Lithuania
2014
Soil water repellency (SWR) it is recognized to be very heterogeneous in time in space and depends on soil type, climate, land use, vegetation and season (Doerr et al., 2002). It prevents or reduces water infiltration, with important impacts on soil hydrology, influencing the mobilization and transport of substances into the soil profile. The reduced infiltration increases surface runoff and soil erosion. SWR reduce also the seed emergency and plant growth due the reduced amount of water in the root zone. Positive aspects of SWR are the increase of soil aggregate stability, organic carbon sequestration and reduction of water evaporation (Mataix-Solera and Doerr, 2004; Diehl, 2013). SWR depe…
Soundscape design through evolutionary engines
2008
Abstract Two implementations of an Evolutionary Sound Synthesis method using the Interaural Time Difference (ITD) and psychoacoustic descriptors are presented here as a way to develop criteria for fitness evaluation. We also explore a relationship between adaptive sound evolution and three soundscape characteristics: keysounds, key-signals and sound-marks. Sonic Localization Field is defined using a sound attenuation factor and ITD azimuth angle, respectively (Ii, Li). These pairs are used to build Spatial Sound Genotypes (SSG) and they are extracted from a waveform population set. An explanation on how our model was initially written in MATLAB is followed by a recent Pure Data (Pd) impleme…
Neighbourhood effects and determinants of population changes in Italy: a spatial perspective
2023
Population trends in Italy are strongly spatially differentiated, with some munic- ipalities showing a systematic loss of population, and others showing an equally continuous demographic increase. Here, we focus our attention on the spatial dimension of population change, looking at how different socio-economic and demographic dimensions affect population changes, as well as their spatial effects. After performing a preliminary descriptive analysis of the trends of population growth and decline in Italy over the last 40 years and the relevant demographic components, we used a spatial Durbin model (SDM) to investigate the potential existence of a diffusion process and the determinants of the…
