COVID-19 and Changes in Social Habits. Restaurant Terraces, a Booming Space in Cities. The Case of Madrid
2021
The COVID-19 pandemic and the fear experienced by some of the population, along with the lack of mobility due to the restrictions imposed, has modified the social behaviour of Spaniards. This has had a significant effect on the hospitality sector, viewed as being an economic and social driver in Spain. From the analysis of data collected in two of our own non-probabilistic surveys (N ~ 8400 and N ~ 2000), we show how, during the first six months of the pandemic, Spaniards notably reduced their consumption in bars and restaurants, also preferring outdoor spaces to spaces inside. The restaurant sector has needed to adapt to this situation and, with the support of the authorities (regional and…
Research on Unrealistic Optimism among HoReCa Workers as a Possible Future Hotspot of Infections
2021
As we are facing a new surge of the highly infectious delta variant of COVID-19, there is an urgent need for research to reduce the harm before this next wave hits. In the present paper, we present data that is alarming. We have found that HoReCa (hotels, restaurants, and catering services) workers, who are highly exposed to many new social interactions in close contact, present an unrealistic optimism (UO) bias: they perceive themselves as less at risk to this virus in comparison to others. From the literature, we already know that individuals holding this view are less involved in preventive actions and present more risky behaviors. In the face of the delta variant, this leads to the conc…
Characteristics of the diffuse astrophysical electron and Tau neutrino flux with six years of IceCube high energy cascade data
2020
We report on the first measurement of the astrophysical neutrino flux using particle showers (cascades) in IceCube data from 2010-2015. Assuming standard oscillations, the astrophysical neutrinos in this dedicated cascade sample are dominated (∼90%) by electron and tau flavors. The flux, observed in the sensitive energy range from 16 TeV to 2.6 PeV, is consistent with a single power-law model as expected from Fermi-type acceleration of high energy particles at astrophysical sources. We find the flux spectral index to be γ=2.53±0.07 and a flux normalization for each neutrino flavor of φastro=1.66-0.27+0.25 at E0=100 TeV, in agreement with IceCube's complementary muon neutrino results and wit…
Euclid preparation XV. Forecasting cosmological constraints for the Euclid and CMB joint analysis
2022
The combination and cross-correlation of the upcoming $Euclid$ data with cosmic microwave background (CMB) measurements is a source of great expectation since it will provide the largest lever arm of epochs, ranging from recombination to structure formation across the entire past light cone. In this work, we present forecasts for the joint analysis of $Euclid$ and CMB data on the cosmological parameters of the standard cosmological model and some of its extensions. This work expands and complements the recently published forecasts based on $Euclid$-specific probes, namely galaxy clustering, weak lensing, and their cross-correlation. With some assumptions on the specifications of current and…
Counselling for physical activity, life-space mobility and falls prevention in old age (COSMOS): protocol of a randomised controlled trial.
2019
IntroductionThe most promising way to promote active life years in old age is to promote regular participation in physical activity (PA). Maintaining lower extremity muscle function with good balance has been associated with fewer falls and the need of help from others. This article describes the design and intervention of a randomised controlled trial (RCT) investigating the effectiveness of a health and PA counselling programme on life-space mobility and falls rates in community-dwelling older adults at the Health Kiosk and/or Service Centre.Methods and analysisCommunity-dwelling men and women (n=450) aged 65 years and over with early phase mobility limitation will be recruited to a 24-mo…
Synthèse de ligands macrocycliques comportant des fragments aromatiques et leur application pour la détection des cations métalliques
2011
The PhD thesis deals with the synthesis of polyazaligands using Pd-catalyzed amination of aryl halides. The manuscript consists of two parts. In the first part the scope of the Pd-catalyzed amination reaction for the synthesis of polyazamacrocyclic ligands is studied. The Pd-catalyzed amination of 2,7-dibromonaphthalene, 3,3’-dibromobiphenyl and 6,6’-dibromo-2,2’-bipyridyl with linear polyamines and oxadiamines is thoroughly investigated, and corresponding nitrogen- and oxygen-containing macrocycles is synthesized in yields up to 45%. The dependence of the formation of macrocycles and cyclic oligomers on the nature of the starting compounds is established. Two alternative approaches to cycl…
One-bond 1 J (15 N,H) coupling constants at sp2 -hybridized nitrogen of Schiff bases, enaminones and similar compounds: A theoretical study
2020
1 J(15 N,H) coupling constants for enaminones and NH-forms of intramolecularly hydrogen-bonded Schiff bases as model compounds for sp2 -hybridized nitrogen atoms are evaluated using density functional theory (DFT) to find the optimal functionals and basis sets. Ammonia is used as a test molecule and its one-bond coupling constant is compared with experiment. A methylamine Schiff base of a truncated molecule of gossypol is used for checking the performance of selected B3LYP, O3LYP, PBE, BHandH, and APFD density functionals and standard, modified, and dedicated basis sets for coupling constants. Both in vacuum and in chloroform, modeled by the simple continuum model of solvent, the modified b…
L’agroforesterie, le futur de la viticulture ?
2020
L’agroforesterie est l’association sur une même parcelle d’une végétation arborée et/ou arbustive, et d’une production végétale, animale ou mixte. Les espèces ligneuses peuvent être réparties uniformément, inégalement ou en bordure de parcelle. Les systèmes agroforestiers fournissent des services écosystémiques et des produits et ce à différentes échelles ; parcelle, exploitation agricole, unité paysagère » (RRAF, 2018). La productivité de ces systèmes dépend de la différence nette entre les avantages et les coûts, entre les utilisations et les composantes biophysiques de l’agroenvironnement. Dans les systèmes de cultures intercalaires, les avantages des arbres sont à la fois économiques et…
Kriminālās domāšanas profila aptaujas sākotnējā adaptācija Latvijā
2019
Pētījuma mērķis bija veikt pirmo adaptācijas posmu Latvijā Kriminālās domāšanas profila aptauju (Criminal Thninking Profile (CTP), Mitchell & Tafrate, 2011) un veikt tās ticamības un validitātes pārbaudi. Kriminālā domāšana ir izziņas process, kas balstās uz kriminālu dzīvesveidu (Walters & White, 1989, kā minēts Tafrate & Mitchell, 2014). Kriminālā domāšana ir atslēga kriminogēnajās vajadzībās, kas balstās uz psihiskajiem traucējumiem, kuri kalpo priekš racionalizācijas ,un iezīmējot aprises noziedzīgai uzvedībai un, kas var paredzēt atkārtotu likumpārkāpumu (Tangney, Mashek, & Stuewig, 2007; Walters, 2012, kā minēts Tangney, Dobbins, Stuewig & Schrader, 2017). Pētījumā tika izvirzīts jaut…
