Features of the Energy Spectrum of Cosmic Rays above 2.5×10$^{18}$ eV Using the Pierre Auger Observatory
2020
We report a measurement of the energy spectrum of cosmic rays above $2.5{\times} 10^{18}$ eV based on $215,030$ events. New results are presented: at about $1.3{\times} 10^{19}$ eV, the spectral index changes from $2.51 \pm 0.03 \textrm{ (stat.)} \pm 0.05 \textrm{ (sys.)}$ to $3.05 \pm 0.05 \textrm{ (stat.)}\pm 0.10\textrm{ (sys.)}$, evolving to $5.1\pm0.3\textrm{ (stat.)} \pm 0.1\textrm{ (sys.)}$ beyond $5{\times} 10^{19}$ eV, while no significant dependence of spectral features on the declination is seen in the accessible range. These features of the spectrum can be reproduced in models with energy-dependent mass composition. The energy density in cosmic rays above $5{\times} 10^{18}$ eV …
Media polarisation over independence for Catalonia. A comparative study of coverage in RT
2019
espanolEl proces catalan ha experimentado una intensa polarizacion mediatica, tanto en medios tradicionales como en redes sociales, donde la corporacion rusa RT ha sido acusada de apoyar al independentismo. Desde una perspectiva cuantitativa, realizamos un analisis comparado de la cobertura en Facebook del proces catalan en las corporaciones RT, BBC y DW. A pesar de la proximidad de RT con el independentismo, los resultados no revelan diferencias significativas entre los medios. Asimismo, las reacciones de los usuarios a las publicaciones en Facebook sugieren su simpatia por el independentismo.

Robust Conditional Independence maps of single-voxel Magnetic Resonance Spectra to elucidate associations between brain tumours and metabolites.
2020
The aim of the paper is two-fold. First, we show that structure finding with the PC algorithm can be inherently unstable and requires further operational constraints in order to consistently obtain models that are faithful to the data. We propose a methodology to stabilise the structure finding process, minimising both false positive and false negative error rates. This is demonstrated with synthetic data. Second, to apply the proposed structure finding methodology to a data set comprising single-voxel Magnetic Resonance Spectra of normal brain and three classes of brain tumours, to elucidate the associations between brain tumour types and a range of observed metabolites that are known to b…
Emotional Distress of Patients at End-of-Life and Their Caregivers: Interrelation and Predictors
2018
Background: Patients at the end of life and their families experience a strong emotional impact. The well-being of these patients and that of their family caregiver are related. Aim: To study the variables related with the emotional well-being of patients with and without cognitive impairment at the end of life and that of their primary family caregivers. Design: Cross- sectional study. Participants: Data was collected from 202 patients at the end of life with different diagnosis (COPD, cancer, and frail elderly) as well as from their respective 202 primary family caregivers. Results: Structural equation models indicated that the emotional state of the patients was best predicted by their f…
A field induced ferromagnetic-like transition below 2.8 K in Li2CuO2: An experimental and theoretical study
1998
The low temperature magnetic properties of the Li2CuO2 compound have been investigated by means of superconducting quantum interference device magnetometry. We find in addition to an antiferromagnetic phase below 9.5 K a ferromagnetic-like steep rise of the magnetization around 2.8 K. The observed low temperature behavior is discussed by considering second and fourth order magnetocrystalline effective anisotropy coefficients, in addition to the exchange couplings reported in the literature. Work at the Institut de Ciencia dels Materials was supported by the Spanish Comisión Interministerial de Ciencia y Technología Grant No. CICYT MAT 96-1037.
A matter of perspective : the cognitive style Field Independence - dependence, and why it matters
2016
Psykologi Herman Witkin aloitti vuonna 1948 kognitiivista ajattelutapaa tutkivan suuntauksen, jossa ihmiset jaettiin kahteen ryhmään: kenttäriippuvaisiin ja kenttäriippumattomiin. Kenttäriippumattomuutta ja -riippuvaisuutta on tutkittu aina 2010 luvulle saakka. Kansainvälisiä tutkimustuloksia löytyy aiheeseen liittyen runsaastikin, mutta Suomessa aihetta ei ole juurikaan tutkittu soveltavan kielitieteen näkökulmasta. Tutkimukset kenttäriippuvaisuudesta ja -riippumattomuudesta antavat viitteitä siihen, että tällä kognitiivisen ajattelun mallilla saattaa olla suurikin vaikutus oppilaiden oppimismenestykseen. Kenttäriippumattomat oppilaat ovat aiempien tutkimusten mukaan itsenäisempiä, havaits…
The corporate image of auditors in a developing audit market within the EU: the case of Spain
2004
This paper examines the images of audit firms in Spain. Spain offers a valuable research context in that it is a relatively new audit market and one where the top company audits are not totally dominated by the large multinational audit firms, allowing for a comparison of the images of such firms against those associated with smaller, national audit firms. The findings of this survey are pertinent given the current level of debate internationally over the role, regulation and quality of auditing services and concerns over the potential impact of recent corporate scandals on auditor reputation. Our study shows that the images of audit firms in Spain have differed on a number of dimensions, m…
A Chronology of Financial Crises for Norway
2010
The paper offers a chronology of financial crises in Norway from her independence in 1814 till present times. Firstly, business cycles, covering almost two hundred years of economic history are mapped. These reveal years of crises in the real economy. These seem to coincide with most of the major financial crises. Secondly, the paper the financial crises are described chronologically. Thirdly, the paper investigates key patterns in credit and money volumes. It concludes that major financial crises typically took place after substantial money and credit expansion causing financial instability, loss of long term equilibriums, overheating and bubbles followed by severe meltdowns in the economy.
Financial Behaviour Under Economic Strain in Different Age Groups: Predictors and Change Across 20 Years
2021
AbstractThe present study examined the multiple micro- and macro-level factors that affect individuals’ financial behaviour under economic strain. The following sociodemographic and economic factors that predict financial behaviour were analysed: age group, year of data gathering, and attitudes towards consumption (economical, deprived, and hedonistic). Subjective financial situations and demographic characteristics were controlled for. Finnish time series data that consisted of five cross-sectional nationally representative surveys were used (n = 10 043). The analyses revealed four types of financial behaviour: cutting expenses, borrowing, increasing income, and gambling. Young adults aged…
A methodology for assessing the effect of correlations among muscle synergy activations on task-discriminating information
2013
Delis, Ioannis | Berret, Bastien | Pozzo, Thierry | Panzeri, Stefano; International audience; ''Muscle synergies have been hypothesized to be the building blocks used by the central nervous system to generate movement. According to this hypothesis, the accomplishment of various motor tasks relies on the ability of the motor system to recruit a small set of synergies on a single-trial basis and combine them in a task-dependent manner. It is conceivable that this requires a fine tuning of the trial-to-trial relationships between the synergy activations. Here we develop an analytical methodology to address the nature and functional role of trial-to-trial correlations between synergy activation…
