Identifying territories using presence-only citizen science data : An application to the Finnish wolf population
2022
Citizens, community groups and local institutions participate in voluntary biological monitoring of population status and trends by providing species data e.g. for regulations and conservation. Sophisticated statistical methods are required to unlock the potential of such data in the assessment of wildlife populations. We develop a statistical modelling framework for identifying territories based on presence-only citizen science data. The framework can be used to jointly estimate the number of active animal territories and their locations in time. Our approach is based on a data generating model which consists of a dynamic submodel for the appearance/removal of territories and an observatio…

A latent profile analysis of trait emotional intelligence to identify beneficial and risk profiles in well-being and job performance: a study among J…
2016
Trait emotional intelligence (EI) is a noteworthy psychological resource in nursing. However, its effects on well-being and job performance are inconsistent. Thus, we explored the latent beneficial and risk profiles of trait EI among 461 Japanese eldercare nurses. Latent profile analysis revealed six latent profiles. In addition, multivariate analysis of covariance (MANCOVA) showed that the profile with the highest overall scores on the trait EI dimensions was associated with the most beneficial outcomes (better well-being, higher job performance). In contrast, the profiles with lower overall scores on the trait EI dimensions showed negative outcomes. Moreover, a disproportional profile, ch…
Riskien havainnollistamisohjelmisto RiskDemo
2018
RiskDemo on vapaasti käytettävä ohjelmistotyökalu, joka on tarkoitettu havainnollistamaan riskejä todennäköisyyslaskennan ja tilastotieteen näkökulmasta. Ohjelmalla voidaan havainnollistaa riskejä monenlaisten graafisten esitysten, taulukoiden ja riskilukujen avulla. Tällä hetkellä sillä voidaan havainnollistaa demografiaa, korko- ja osakesijoittamista sekä klassista vararikkoteoriaa. Tässä artikkelissa esitellään RiskDemo-ohjelmiston ominaisuudet ja opastetaan sen käyttämiseen riskien havainnollistamisessa. Lukija voi RiskDemon avulla tutustua moniin riskienhallinnan avainkäsitteisiin havainnollisessa ja konkreettisessa muodossa. peerReviewed
Predicting the 2000‐m Rowing Ergometer Performance from Anthropometric, Maximal Oxygen Uptake and 60‐s Mean Power Variables in National Level Young R…
2020
Abstract Many studies reported various relationships between 2000-m rowing performance and anthropometric as well as metabolic variables, however, little is known about 60-s mean power in elite youth athletes. The aim of this study was to develop different regression models to predict 2000-m rowing indoor performance time (t2000) using anthropometric variables, maximal oxygen uptake (VO2max) and mean power established during a 60-s all-out test (W60) in national elite youth rowers. Fifteen youth male Italian rowers (age: 15.7 ± 2.0 years; body height: 176.0 ± 8.0 cm; body mass: 71.2 ± 10.0 kg) performed an incremental maximal test, a 60-s all-out test and a 2000-m race simulation using a Co…
The participant interview: a method to understand the individual's experience in the car
2019
L’individu dans son automobile, durant ses déplacements quotidiens, habite d’une façon ou d’une autre l’espace circonscrit dans lequel il se trouve alors. De ce point de vue, il apparaît nécessaire de développer une ethno-sociologie des manières d’habiter son automobile. Pour atteindre cette ambition heuristique, nous préciserons ici les termes de cette méthode que nous nommons « entretien participant ». Hybridant les méthodes de l’entretien et de l’observation participante, l’entretien du rapport de l’individu contemporain à son automobile alternant sans cesse entre réflexivité et routines, entre repli sur soi et disponibilité au monde et à soi.
Safety Culture and Safety Performance in High-Reliability Organizations: A Synthesis of IDOCAL’S Contributions to the Literature
2020
Improving safety culture and safety performance is a constant concern for companies operating in high-risk environments. For almost two decades, IDOCAL (the Research Institute of Personnel Psychology, Organizational Development and Quality of Working Life) has been contributing to advancing our understanding of these important concepts through theoretical development and empirical research. The objective of this article is to synthesize these contributions. Some of the most prominent are (1) the development of a framework for the evaluation of safety culture and its correlates based on the AMIGO model, (2) the establishment of the empowering leadership model as a valuable concept in safety …
Improving the Downwind Sail Design Process by Means of a Novel FSI Approach
2021
The process of designing a sail can be a challenging task because of the difficulties in predicting the real aerodynamic performance. This is especially true in the case of downwind sails, where the evaluation of the real shapes and aerodynamic forces can be very complex because of turbulent and detached flows and the high-deformable behavior of structures. Of course, numerical methods are very useful and reliable tools to investigate sail performances, and their use, also as a result of the exponential growth of computational resources at a very low cost, is spreading more and more, even in not highly competitive fields. This paper presents a new methodology to support sail designers in ev…
Spatial data fusion and analysis for soil characterization: a case study in a coastal basin of south-western Sicily (southern Italy)
2012
Salinization is one of the most serious problems confronting sustainable agriculture in semi-arid and arid regions. Accurate mapping of soil salinization and the associated risk represent a fundamental step in planning agricultural and remediation activities. Geostatistical analysis is very useful for soil quality assessment because it makes it possible to determine the spatial relationships between selected variables and to produce synthetic maps of spatial variation. The main objective of this paper was to map the soil salinization risk in the Delia-Nivolelli alluvial basin (south-western Sicily, southern Italy), using multivariate geostatistical techniques and a set of topographical, phy…

Objetivo. Explorar la estructura factorial de una adaptación al castellano del "Maslach Burnout Inventory-General Survey" (MBI-GS). Material y métodos. La muestra la integraron 149 policías municipales de Tenerife, España, a quienes se les aplicó el cuestionario en 1999. Se realizó un análisis factorial mediante Componentes Principales y rotación Varimax. Resultados. Cuatro factores tuvieron eigenvalues mayores que 1. En el Factor I se agruparon los items de Eficacia Profesional, en el Factor II tres items de Cinismo, en el Factor III los items de Agotamiento, y en el Factor IV dos items de Cinismo. Posteriormente se realizó otro análisis ajustando a tres la extracción de factores. La soluc…
