An algorithm for earthquakes clustering based on maximum likelihood
2007
In this paper we propose a clustering technique set up to separate and find out the two main components of seismicity: the background seismicity and the triggered one. We suppose that a seismic catalogue is the realization of a non homogeneous space-time Poisson clustered process, with a different parametrization for the intensity function of the Poisson-type component and of the clustered (triggered) component. The method here proposed assigns each earthquake to the cluster of earthquakes, or to the set of independent events, according to the increment to the likelihood function, computed using the conditional intensity function estimated by maximum likelihood methods and iteratively chang…
Determinants of individual tourist expenditure as a network: Empirical findings from Uruguay
2014
Abstract This paper introduces the use of graphical models for assessing the determinants of individual tourist spending. These models have the advantage of synthesizing and visualizing the relationships occurring within large sets of random variables, through an easy to interpret output. To this end, individual data from a large official survey of international tourists in Uruguay are used. Symmetric conditional independence structures are first investigated. Then subgraphs of each expenditure item's neighbourhood are extracted in order to assess the impact of main effects and interactions through proportional ordinal logistic regression. Results highlight the marginal role of socio-demogr…
A particle based simulation model for glacier dynamics
2013
This publication is contribution number 22 of the Nordic Centre of Excellence SVALI, “Stability and Variations of Arctic Land Ice”, funded by the Nordic Top-level Research Initiative (TRI). The work has been supported by the SVALI project through the University of Lapland, Arctic Centre, and through the University Centre in Svalbard. Funding was also provided by the Conoco-Phillips and Lunding High North Research Program (CRIOS: Calving Rates and Impact on Society). A particle-based computer simulation model was developed for investigating the dynamics of glaciers. In the model, large ice bodies are made of discrete elastic particles which are bound together by massless elastic beams. These…
Helical Shift Mechanics of Rubber V-Belt Variators
2011
A very common configuration of V-belt variators for motorcycles considers the correction of the belt tensioning depending on the resistant torque by means of suitable helical-shaped tracks allowing the driven half-pulleys to close/open. The theoretical model for belt-pulley coupling is rather complex for this configuration, where one half-pulley may run in advance and the other one behind with respect to the belt, and requires the repeated numerical solution of a strongly nonlinear differential system by a sort of shooting technique, until all the operating conditions are fulfilled (angular contact extent, torque, and axial force). After solving the full equations, the present study develop…
Modeling of 137Cs migration in soils using an 80-year soil archive: role of fertilizers and agricultural amendments
2008
An 80-year soil archive, the 42-plot experimental design at the INRA in Versailles (France), is used here to study long-term contamination by 137Cs atmospheric deposition and the fate of this radioisotope when associated with various agricultural practices: fallow land, KCl, NH4(NO3), superphosphate fertilizers, horse manure and lime amendments. The pertinence of a simple box model, where radiocaesium is supposed to move downward by convectional mechanisms, is checked using samples from control plots which had been neither amended, nor cultivated since 1928. This simple model presents the advantage of depending on only two parameters: α, a proportional factor allowing the historical atmosph…
Agreements regarding the property relations of transnational couples and their effects under the application of the twin regulations
2021
It is a true and verifiable fact that the family institution has evolved over recent decades in Europe and throughout the world, but not uniformly or at the same time. This is because it is influenced by social and cultural connotations specific to each State. All of which are respected under EU Regulations 2016/1103 and 2016/1104. This work analyses the Twins Regulations, that gives the couples the possibility of choosing the jurisdiction (art. 7) and applicable legal system underpinning the property consequences of the marriage and registered partnerships (art. 22.1). However, we try to show you these rules absolute freedom of choice is not granted to the parties, because this freedom is …
On the calculation of derived variables in the analysis of multivariate responses
1992
AbstractThe multivariate regression of a p × 1 vector Y of random variables on a q × 1 vector X of explanatory variables is considered. It is assumed that linear transformations of the components of Y can be the basis for useful interpretation whereas the components of X have strong individual identity. When p ≥ q a transformation is found to a new q × 1 vector of responses Y∗ such that in the multiple regression of, say, Y1∗ on X, only the coefficient of X1 is nonzero, i.e. such that Y1∗ is conditionally independent of X2, …, Xq, given X1. Some associated inferential procedures are sketched. An illustrative example is described in which the resulting transformation has aided interpretation.
Cognitive behavioural therapy and mindfulness for stress and burnout : a waiting list controlled pilot study comparing treatments for parents of chil…
2018
Background Parents of children with chronic conditions often experience a crisis with serious mental health problems for themselves as a consequence. The healthcare focus is on the children; however, the parents often worry about their children's health and future but are seldom offered any counselling or guidance. Aim The aim of this study was to investigate the effectiveness of two group-based behavioural interventions on stress and burnout among parents of children with chronic conditions. Design, participants and setting After a waiting list control period (n = 28), parents were offered either a cognitive behavioural (CBT, n = 10) or a mindfulness program (MF, n = 9). Results Both inter…
Eldercare work and technology. 2019 University of Jyväskylä survey study on eldercare work : Overview of survey data
2019
University of Jyväskylä has launched a survey study on eldercare work aimed to obtain information on 1) employees working with services for older people, 2) the nature of the work and working conditions in services for older people and 3) a current view of the use of technology in services for older people. The goal is to examine how the use of digital technologies is linked to working conditions, daily work routines and care relationships and to monitor the nature of care work and its digitalisation during 2019-2025. The first baseline survey was conducted on April 2019 resulting with 6 903 answers and of the respondents, 3,758 joined the respondent panel. The 2019 survey data shows that i…
Ylikuormitusta, lähijohtajan tuen puutetta vai vääränlaisia tehtäviä : miksi yhä useammat vanhustyöntekijät harkitsevat työnsä lopettamista?
2021
Yhä useampi suomalainen vanhustyöntekijä harkitsee nykyisen työnsä lopettamis-ta. Artikkelin mukaan työntekijöiden psykofyysinen kuormitus on selvästi keskeisin lopettamisaikeita ennustava tekijä. Lisäksi lopettamisaikeita ennustavat epäkohdat työn sisällössä ja lähijohtamisessa. Nuoret, yrityksissä työskentelevät, osa-aikatyötä tekevät ja yli kahden vuoden hoitotyön koulutuksen saaneet vanhustyöntekijät har-kitsivat työnsä lopettamista muita vastaajia tavallisemmin. Increasing numbers of employees working in the care of older people in Finland are seriously considering leaving their jobs. This article examines factors that predict care workers’ leaving intentions. The data consist of NORDC…
