“I want creative neighbours”. Do creative service industries spillovers cross regional boundaries?
2014
The occurrence of creative service industries (CSI) is a strong determinant of differences in wealth amongst European regions. However, it is unknown if the strong effects are limited to occurring within regional boundaries or whether there are spillover effects into neighbouring regions. The purpose of this paper is to assess the existence of CSI spillover effects on the wealth of neighbouring regions. CSI and spillovers are integrated into both an empirical model and an endogenous growth model. Both models are estimated for a sample of 250 regions in the European Union in 2008. We find that most of the effects of CSI take place within regions, although there is also evidence that CSI has …
Crime Analysis of the Metropolitan Region of Santiago de Chile: A Spatial Panel Data Approach
2022
The aim of our work is to determine the influence that socio-economic and demographic factors have had on crimes that have taken place during the period 2010–2018 in the communes of the Metropolitan Region of Chile, as well as the existence of possible spatial or temporal effects. We address 12 kinds of crime that we have grouped into two main types: against people and against property. Our interest focuses on crimes against people, using crimes against property as an additional covariate in order to investigate the existence of the broken-windows phenomenon in this context. The model chosen for our analysis is a spatial panel model with fixed effects. The results highlight that covariates …

Geostatistics for Mapping Leaf Area Index over a Cropland Landscape: Efficiency Sampling Assessment
2010
This paper evaluates the performance of spatial methods to estimate leaf area index (LAI) fields from ground-based measurements at high-spatial resolution over a cropland landscape. Three geostatistical model variants of the kriging technique, the ordinary kriging (OK), the collocated cokriging (CKC) and kriging with an external drift (KED) are used. The study focused on the influence of the spatial sampling protocol, auxiliary information, and spatial resolution in the estimates. The main advantage of these models lies in the possibility of considering the spatial dependence of the data and, in the case of the KED and CKC, the auxiliary information for each location used for prediction pur…
Crystal structure of 1-(2-fluorobenzoyl)-2,7-dimethoxynaphthalene
2014
The asymmetric unit of the compound contains two independent conformers. Each conformer is stacked along the a axis to form columns through van der Waals interactions only.
Characterization of spatial porosity and mineral distribution of crystalline rock using X-ray micro computed tomography, C-14-PMMA autoradiography an…
2019
The spatial porosity and mineral distribution of geological materials strongly affects transport processes in them. X-ray micro computed tomography (X-mu CT) has proven to be a powerful tool for characterizing the spatial mineral distribution of geological samples in 3-D. However, limitations in resolution prevent an accurate characterization of pore space especially for tight crystalline rock samples and 2-D methods such as C-14-polymethylmethacrylate (C-14-PMMA) autoradiography and scanning electron microscopy (SEM) are needed. The spatial porosity and mineral distributions of tight crystalline rock samples from Aspo, Sweden, and Olkiluoto, Finland, were studied here. The X-mu CT were use…

Spatial updating and domain expertise: the case of dancers: Poster
2021
Dancers are a unique group of individuals who routinely engage in coordi nated highly skilled performances with others in the immediate environment. Previous research suggests that, compared to non-dancers, dancers have superior cognitive and motor skills, such as memory, posture control and balance. Although differences between dancers and non-dancers are reported for spatial skills as well, it is still unknown whether they are the result or the cause of dancing experience, with individuals having superior skills being more likely to take up dancing. To answer this question, we asked novices with no formal dance experience to attend dance lessons for a year. To investigate the effects of d…
