Online interventions to prevent mental health problems implemented in school settings: the perspectives from key stakeholders in Austria and Spain
2021
Abstract Background Schools are key settings for delivering mental illness prevention in adolescents. Data on stakeholders’ attitudes and factors relevant for the implementation of Internet-based prevention programmes are scarce. Methods Stakeholders in the school setting from Austria and Spain were consulted. Potential facilitators (e.g. teachers and school psychologists) completed an online questionnaire (N=50), policy makers (e.g. representatives of the ministry of education and health professional associations) participated in semi-structured interviews (N=9) and pupils (N=29, 14–19 years) participated in focus groups. Thematic analysis was used to identify experiences with, attitudes a…
An International Survey of Quality and Safety Programs in Radiology
2021
Purpose: The aim of this study was to determine the status of radiology quality improvement programs in a variety of selected nations worldwide. Methods: A survey was developed by select members of the International Economics Committee of the American College of Radiology on quality programs and was distributed to committee members. Members responded on behalf of their country. The 51-question survey asked about 12 different quality initiatives which were grouped into 4 themes: departments, users, equipment, and outcomes. Respondents reported whether a designated type of quality initiative was used in their country and answered subsequent questions further characterizing it. Results: The re…
Sampling in Local Tourism Quantification: Critical Issues and Field Experience
2013
The aim of this paper is to detail some issues relating to tourist sampling by means of three case studies. Tourism quantification issues and solutions will be illustrated in three paradgmatic situations: sampling in a self-contained context with multiple access points (an Island in Aeolian archipelago), tourism in a seaside town, and nautical tourism. In these contexts the issue of building a space-time grid to circumscribe the target population is made more complex by the mobile nature of these populations.
Tyttöjen ja poikien väliset erot seksuaalisesta hyväksikäytöstä kertomisessa
2020
Tytöt ja pojat eroavat toisistaan siinä, kuinka he kertovat kokemastaan seksuaalisesta hyväksikäytöstä. Kokemukset jäävät usein myös kokonaan aikuisille kertomatta. Hyväksikäytön kokemusten tunnistaminen, asian puheeksi ottaminen ja siihen puuttuminen on edellytys myös laajemmalle toimintakulttuurin kehittämiselle sekä asenteellisille ja rakenteellisille muutoksille. This article addresses the frequency of child sexual abuse and its disclosure from the perspective of girls and boys between ages 11 and 17 years. It is based on data from two population-based studies in the Child Victim Surveys 2008 (N = 13,459) and 2013 (N = 11,364), with sexual abuse examined from the perspectives of disclos…
A Multi-Projector Calibration Method for Virtual Reality Simulators with Analytically Defined Screens
2017
The geometric calibration of projectors is a demanding task, particularly for the industry of virtual reality simulators. Different methods have been developed during the last decades to retrieve the intrinsic and extrinsic parameters of projectors, most of them being based on planar homographies and some requiring an extended calibration process. The aim of our research work is to design a fast and user-friendly method to provide multi-projector calibration on analytically defined screens, where a sample is shown for a virtual reality Formula 1 simulator that has a cylindrical screen. The proposed method results from the combination of surveying, photogrammetry and image processing approac…
A soil biodiversity survey coupled with the national soil quality monitoring network?
2021
International audience; Despite its importance for human activities, soil biodiversity remains largely unknown and threatened. Aware of the need for large-scale monitoring, we studied the feasibility to add a soil biodiversity survey (RMBS-Biodiversity) to the already existing French soil quality monitoring network (RMQS). We worked with soil biodiversity experts to couple RMBS-Biodiversity with RMQS i.e. to choose soil taxons and functions, the methodologies and the sampling design. According to the experts, the sampling design of RMQS fits with a soil biodiversitysurvey. We propose sampling protocols for i) bacteria and fungi, ii) protists, iii) nematodes, iv) mesofauna (particularly spri…

Probabilistic and preferential sampling approaches offer integrated perspectives of Italian forest diversity
2023
Aim: Assessing the performances of different sampling approaches for documenting community diversity may help to identify optimal sampling efforts and strategies, and to enhance conservation and monitoring planning. Here, we used two data sets based on probabilistic and preferential sampling schemes of Italian forest vegetation to analyze the multifaceted performances of the two approaches across three major forest types at a large scale. Location: Italy. Methods: We pooled 804 probabilistic and 16,259 preferential forest plots as samples of vascular plant diversity across the country. We balanced the two data sets in terms of sizes, plot size, geographical position, and vegetation types. F…
Integrating vehicle specific power methodology and microsimulation in estimating emissions on urban roundabouts
2021
In this study pollutant emissions were estimated from VSP modal emission rates and the distribution of time spent in each VSP mode obtained from the speed profiles both gathered in the field and simulated in AIMSUN at a sample of urban roundabouts. The versatility of the micro-simulation model for a calibration aimed at improving accuracy of emissions estimates was tested in order to ensure that second-by-second trajectories experienced in the field by a test vehicle through the sampled roundabouts properly reflected the simulated speed profiles. The first results which the thesis will refer, confirmed the feasibility of the smart approach that integrates the use of field-observed and simul…
