Nasjonalt innført! Nasjonalt behov? : Eksperter i et innbyggerpanels forventninger og opplevelser til Nasjonal kjernejournal – Et Delphistudie

2017

Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2017 Technology plays a part in nearly every aspect of life. Electronic self-services such as online banking, control of tax returns, or application for construction permits are daily events unfolding online. Health services are coming along, and their last addition is the national medical core journal. Based on numbers that indicate a low utilization, full adoption by the citizens of the solution seems absent. The purpose of this study is to research what expectations and experiences the citizens have to the national medical core journal. The issue for the study is, "What are the most important factors to contribute…

L’ADULTO COME SPECCHIO. MODALITÀ COMUNICATIVE E APPRENDIMENTO

2021

Numerose ricerche sull’infanzia condotte a partire dal secolo scorso, hanno mostrato come i bambini, fin dai primi mesi di vita, siano attivi e propositivi nella interazione con gli altri esseri umani. In una prospettiva educativa, di promozione dei processi di apprendimento e di sostegno alla costruzione di una immagine di sé positiva e fiduciosa nelle proprie potenzialità, sono di grande importanza le modalità comunicative e relazionali degli adulti significativi. A tali modalità farò riferimento nel mio contributo, soffermandomi sul rispecchiamento verbale e non verbale, nelle sue diverse forme, approfondendone le ragioni teoriche e metodologiche e riflettendo su come possa attuarsi una …

Facing the Normative Challenges : The Potential of Reflexive Historical Research

2016

This article explores methodological problems of qualitative research templates, that is, the Eisenhardt and the Gioia case study approaches, which are relevant for the business and society (B&S) scholarship and outlines a reflexive historical research methodology that has the potential to face these challenges. Building on Hans-Georg Gadamer’s philosophical hermeneutics, we draw critical attention to qualitative B&S research and frame the methodological problems identified as the normative challenges of qualitative research, that is, to productively deal with both the researchers’ norms and the research subjects’ norms. We then introduce the reflexive historical case study (RHCS), …

Modeling long-range memory with stationary Markovian processes

2009

In this paper we give explicit examples of power-law correlated stationary Markovian processes y(t) where the stationary pdf shows tails which are gaussian or exponential. These processes are obtained by simply performing a coordinate transformation of a specific power-law correlated additive process x(t), already known in the literature, whose pdf shows power-law tails 1/x^a. We give analytical and numerical evidence that although the new processes (i) are Markovian and (ii) have gaussian or exponential tails their autocorrelation function still shows a power-law decay =1/T^b where b grows with a with a law which is compatible with b=a/2-c, where c is a numerical constant. When a<2(1+c) th…

Status of Advanced Virgo

2017

The LIGO and the Virgo collaborations have recently announced the first detections of Gravitational Waves. Due to their weak amplitude, Gravitational Waves are expected to produce a very small effect on free-falling masses, which undergo a displacement of the order of 10-18 m for a Km-scale mutual distance. This discovery showed that interferometric detectors are suitable to reveal such a feeble effect, and therefore represent a new tool for astronomy, astrophysics and cosmology in the understanding of the Universe. To better reconstruct the position of the Gravitational Wave source and increase the signal-to-noise ratio of the events by means of multiple coincidence, a network of detectors…

Limits on point-like sources of ultra-high-energy neutrinos with the Pierre Auger Observatory

2019

With the Surface Detector array (SD) of the Pierre Auger Observatory we can detect neutrinos with energy between 1017 eV and 1020 eV from point-like sources across the sky, from close to the Southern Celestial Pole up to 60 in declination, with peak sensitivities at declinations around ∼-53 and ∼+55, and an unmatched sensitivity for arrival directions in the Northern hemisphere. A search has been performed for highly-inclined air showers induced by neutrinos of all flavours with no candidate events found in data taken between 1 Jan 2004 and 31 Aug 2018. Upper limits on the neutrino flux from point-like steady sources have been derived as a function of source declination. An unrivaled sensit…

Existence of three solutions for a mixed boundary value system with (p_1,...,p_m)-Laplacian

2014

In this paper we prove the existence of at least three weak solutions for a mixed boundary value system with (p_1,,...,p_m)-Laplacian. The approach is based on variational methods.

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…

KERNEL ESTIMATION OF THE TRANSITION DENSITY IN BIFURCATING MARKOV CHAINS

2023

We study the kernel estimator of the transition density of bifurcating Markov chains. Under some ergodic and regularity properties, we prove that this estimator is consistent and asymptotically normal. Next, in the numerical studies, we propose two data-driven methods to choose the bandwidth parameters. These methods are based on the so-called two bandwidths approach.
