Tourism statistics and unobserved tourism: empirical evidences in Sicily

2013

Despite its strategic importance, accurately measuring visitor attendance has been a challenging and problematic exercise for tourism managers for decades. Consequently, the primary aim of tourism statistics of accurately quantify tourism flows has been only partially achieved; indeed at a lower territorial scale tourism statistics appear less precise and accurate. The aim of this paper is: to introduce the concept of unobserved tourism, by highlighting the main limits of official statistical systems (with a special focus on the European statistical system on tourism statistics; to formalize a theoretical model in which tourism nights and trips in a given destination are decomposed intoobse…

Geostatistical computing of acoustic maps in the presence of barriers

2009

Acoustic maps are the main diagnostic tools used by authorities for addressing the growing problem of urban acoustic contamination. Geostatistics models phenomena with spatial variation, but restricted to homogeneous prediction regions. The presence of barriers such as buildings introduces discontinuities in prediction areas. In this paper we investigate how to incorporate information of a geographical nature into the process of geostatistical prediction. In addition, we study the use of a Cost-Based distance to quantify the correlation between locations.

Hacer Teatro: beneficios para el desarrollo positivo en adolescentes

1970

Este estudio se centra en analizar las opiniones de los adolescentes sobre los beneficios que para ellos supone participar en experiencias teatrales. Se han identificado a partir de seis grupos foco, con una muestra de 53 participantes, de entre 12 y 20 años. Los resultados apuntan a que dichas prácticas: promueven habilidades personales; ofrecen una oportunidad para explorar y expresar sentimientos; proporcionan un contexto de apoyo y seguridad; posibilitan hacer amigos; incrementan habilidades comunicativas; proporcionan recursos para ser empleados en otros ámbitos y momentos de la vida; ayudan a formar la identidad y a mejorar la autoestima; desarrollan destrezas para entender a los otro…

Quick Affective Judgments: Validation of a Method for Primed Product Comparisons

2015

A method for primed product comparisons was developed, based on the methodological considerations of emotional appraisal process and affective mental contents. The method was implemented as a computer tool, which was utilised in two experiments (N = 18 for both). Ten adjectives served as primes, and five drinking glass pictures as stimuli. Participants' task was to choose a preference between two glasses, given the priming adjective. The results validate the method by providing test-retest reliability measures and showing convergence with questionnaires. Further, different evaluation times between the primes and the stimuli reveal the existence of different mental processes associated with …

Identifiability problem for recovering the mortality rate in an age-structured population dynamics model

2014

In this article is studied the identifiability of the age-dependent mortality rate of the Von Foerster–Mc Kendrick model, from the observation of a given age group of the population. In the case where there is no renewal for the population, translated by an additional homogeneous boundary condition to the Von Foerster equation, we give a necessary and sufficient condition on the initial density that ensures the mortality rate identifiability. In the inhomogeneous case, modelled by a non-local boundary condition, we make explicit a sufficient condition for the identifiability property, and give a condition for which the identifiability problem is ill-posed. We illustrate this latter case wit…

Analysis of ecological shifts in the two‐age structured population model with Allee effect and environmental noise

2020

We study noise-induced transformations in the two-age structured population model with the Allee effect and environmental fluctuations. In this bistable model, ecological shifts are associated mathematically with random transitions between basins of coexisting attractors. The following phenomena are revealed and studied: (i) noise-induced extinction, (ii) stochastic regeneration, and (iii) excitement of random mixed-mode oscillations. Constructive abilities of the analytical method of confidence domains are demonstrated in the parametric study of these phenomena.

Bone marrow-derived progenitors are greatly reduced in patients with severe COPD and low-BMI.

2009

Chronic obstructive pulmonary disease (COPD) patients have reduced circulating hemopoietic progenitors. We hypothesized that severity of COPD parallels the decrease in progenitors and that the reduction in body mass index (BMI) could be associated with more severe bone marrow dysfunction. We studied 39 patients with moderate to very severe COPD (18 with low-BMI and 21 with normal-BMI) and 12 controls. Disease severity was associated to a greater reduction in circulating progenitors. Proangiogenetic and inflammatory markers correlated with disease severity parameters. Compared to normal-BMI patients, low-BMI patients showed: greater reduction in circulating progenitors; higher VEGF-A, VEGF-C…

Russian speakers’ media engagement and acculturation in Finland and Latvia

2022

AbstractThis comparative study looks into Russian speakers’ acculturation in Finland and Latvia by contrasting their cultural involvement and cultural preference Carlson and Güler (J Int Migr Integr 19:625–647, 2018. 10.1007/s12134-018-0554-4) with their self-reported news media use. Drawing on survey data collected from both countries (N = 224), the findings show that participants in both countries scored closer to biculturalism than monoculturalism. Majority of the respondents report predominantly engaging with non-Russian news media sources. However, regardless of the societal context, respondents who were more engaged with Russian news media sources also scored higher on cultural prefer…
