Community detection of seismic point processes

2022

In this paper, we combine robin and Local Indicators of Spatio-Temporal Association (LISTA) functions. robin is an R package to assess the robustness of the community structure of a network found by one or more methods to give indications about their reliability. We use it to propose a classification algorithm of events in a spatio-temporal point pattern, by means of the local second-order characteristics and the community detection procedure in network analysis. We demonstrate the proposed procedure on a real data analysis on seismic data.

Modelling analysis of distribution network filling process during intermittent supply

2009

The paper presents the modeling results of the filling process of a water distribution network subjected to intermittent supply. The local tanks built by users for reducing their vulnerability to intermittent supply increase user water demand at the beginning of the service period and the time required for completely fill the network. Such a delicate process is responsible of the inequalities taking part among users. Users located in advantaged positions can receive water resources soon after the beginning of the service period while disadvantaged users have to wait until the network is full. Such an highly dynamic process requires ad-hoc models to be developed in order to obtain reliable r…

2016

The economy, nowadays, is leading us toward a huge crisis. An environmental crisis, a new financial crisis and finally a war crisis.

Several propositions are made about education, culture and economy to obtain sustainable changes in the economic landscape and in order to promote entrepreneurship in this fictive economy.

Verkkomedian ominaispiirteiden arvo asiakkaalle

2015

Mediat elävät murrosta, joka johtuu digitalisoitumisesta ja internetin yleistymi-sestä. Ongelmana on se, että medioiden perinteiset toimintatavat ja asiakkaan kulutustottumukset eivät sovellu yksiin. Asiakas pystyy saamaan tietoa milloin vain ja mistä vain. Perinteisen median toimintatavat eivät pysty vastaamaan tähän tarpeeseen. Tästä syystä mediat ovat siirtyneet vauhdilla verkkoon tar-joamaan sisältöä. Verkossa ongelmaksi on muodostunut kova kilpailu, joka on pudottanut valtavirtauutisten arvon lähes ilmaiseksi. Vaihtoehtojen ollessa laa-jat asiakkaalle ja medioiden väliset vaihtokustannukset pienet, asiakkaat eivät ole olleet valmiit maksamaan mediatuotteista verkossa. Asiakkaan maksuha…

Customer Value Framework and Recommendation Intention: The Moderating Role of Customer Characteristics in an Online Travel Community

2019

The aim of this study was to develop and test a model that examined the interactions among the customer value framework, recommendation intention and customer characteristics in an online travel community (OTC). Data were obtained using Amazon Mechanical Turk from 251 members of an OTC as a sample. The partial least squares method was used to analyse the data. We found that all the variables of the customer value framework, including functional value, hedonic value and social value, were positively related to recommendation intention. In addition, using multi-group analyses, the study found differences between how different customer segments perceive each of the value dimensions and their e…

Appropriateness of surgery performed for abdominal aortic aneurysm at tertiary hospitals in Spain

2021

Background: The aim of this study was to analyze the appropriateness of the type of repair (open or endovascular) performed for abdominal aortic aneurysm (AAA) in five university hospitals in Spain, according to evidence-based recommendations. Methods: A multicenter, retrospective cross-sectional study of patients with AAA who underwent elective open surgical repair (OSR) or endovascular aneurysm repair (EVAR). Data were collected on demographic and clinical variables and type of surgical repair. A pair of vascular surgeons from each participating hospital performed a blinded assessment based on GRADE recommendations. The concordance between the two evaluators and the agreement between thei…

Energy Drink Consumption Among Finnish Adolescents: Prevalence, Associated Background Factors, Individual Resources, and Family Factors.

2020

Objectives: Energy drink consumption among adolescents has become a notable global phenomenon, and has been associated with numerous negative health outcomes. In order to understand the popularity of energy drinks among adolescents, and to target interventions, it is important to identify the determinants underpinning consumption. Methods: The nationally representative data (cross-sectional) were drawn from the Health Behaviour in School-aged Children (HBSC) surveys, conducted in 2014 and 2018, each comprising 13- and 15-year-old Finnish adolescents (n = 7405). Results: Weekly energy drink consumption increased among Finnish adolescents between 2014 (18.2%) and 2018 (24.4%), especially amon…

Pre-service subject teachers’ personal teacher characterisations after the pedagogical studies

2020

This study explored how five pre-service subject teachers characterised themselves as teachers after completing their year-long pedagogical studies in a Finnish university. Our narrative analysis of the interview data showed that the students shared a social representation of a past teacher characterised by wide power and emotional distance between pupils and the teacher. The students differentiated themselves from this kind of teacher character, and rather positioned themselves as interactive and caring educators identifying with their own ideal teachers as well as meaningful learning experiences in the pedagogical studies. Consequently, the study showed that engaging pre-service subject t…
