Data from: Low but contrasting neutral genetic differentiation shaped by winter temperature in European great tits
2015
Gene flow is usually thought to reduce genetic divergence and impede local adaptation by homogenising gene pools between populations. However, evidence for local adaptation and phenotypic differentiation in highly mobile species, experiencing high levels of gene flow, is emerging. Assessing population genetic structure at different spatial scales is thus a crucial step towards understanding mechanisms underlying intraspecific differentiation and diversification. Here, we studied the population genetic structure of a highly mobile species – the great tit Parus major – at different spatial scales. We analysed 884 individuals from 30 sites across Europe including 10 close-by sites (< 50 km)…
- SHADOW PRICES AND DISTANCE FUNCTIONS: AN ANALYSIS FOR FIRMS OF THE SPANISH CERAMIC PAVEMENTS INDUSTRY.
1999
This paper deals with the calculation of shadow prices for two industrial wastes generated on their production processes by a sample of eighteen firms belonging to the Spanish ceramic pavements industry. These prices are used to construct a corrected index of productivity which allows for considering wastes going with the production of marketable goods. It is followed the ethodologicalapproach first proposed by Färe, Grosskopf, Lovell y Yaisawarng (1993), which establishes a duality between distance and revenue functions. The shadow prices obtained for watery muds and used oils allow to measure in terms of a loss of marketable output the cost of achieving a marginal reduction in the product…
Development of Network Security Education
2021
Distance education has grown tremendously over the last decade. Internet technologies have enabled a large-scale dispensation of lectures, exercises, and training. Virtual Learning Management Systems (LMSs) offer a number of tools to realize distance education and distance learning. In this work, we present a virtual system architecture for training cyber security professionals with hands-on skills. The architecture is based on a VirtualBox virtualization environment. Guest machines are installed on an instance of VirtualBox. The installed environment offers a safe and isolated workbench for experiments. After installation and configuration of the environment, students perform a number of i…
Etäteknologian vaikuttavuus vyötärön ympärysmittaan ja rasvaprosenttiin liikuntaa sisältävissä painonpudotusinterventioissa : järjestelmällinen kirja…
2017
Teknologian vaikuttavuutta painonhallintaan on tutkittu paljon, mutta tulokset ovat olleet ristiriitaisia (Hutchesson ym. 2015). Painonpudotustutkimuksissa tulosmuuttujina on yleensä ollut kehon massa tai painoindeksi. Nämä eivät kuitenkaan erottele lihaksiin liittyvää massaa rasvaan liittyvästä massasta. Tämän tutkimuksen tarkoituksena oli tutkia etäteknologian vaikuttavuutta vyötärön ympärysmittaan ja rasvaprosenttiin liikuntaa sisältävissä painonpudotusinterventiossa verrattuna tavanomaiseen hoitoon. Aineistoa kerättiin kahdeksasta tietokannasta: EMBASE, CENTRAL, Ovid MEDLINE, CINAHL, PsycINFO, PEDro, WoS sekä OT-Seeker. Haku tehtiin ajalta 1/2000 – 1/2016 hyödyntäen Cochrane-katsausten …
Sports injuries in Finnish elite cross-country skiers, swimmers, long-distance runners and soccer players
2011
In sports with different exercise-loading characteristics, acute and overuse injury profiles and gender differences in injuries were investigated. In addition, trainingrelated risk factors for overuse injuries in endurance athletes were studied. This twelve-month retrospective questionnaire study comprised Finnish elite crosscountry skiers (n=149), swimmers (n=154), long-distance runners (n=143) and soccer players (n=128) aged 15–35 years. Questionnaires were sent to the athletes in each sports at the end of the 2006 competition season. Athletes who ended their sports career because of injury were studied in more detail by means of a telephone interview (n=20) 7-11 months after the question…
Problem dystansu władzy w szwedzkich materiałach dydaktycznych jako przykład dobrych praktyk
2016
Tekst stanowi przyczynek do dyskusji nad zjawiskiem społecznego konstruowania nierówności przez system edukacji. Autorka, na przykładzie szwedzkich podręczników szkolnych, dokonuje analizy ich zawartości pod kątem teorii wymiarów kultury G. Hofstede, koncentrując się na jednym z wymiarów (dystansu władzyj. Taki sposób analizy może stanowić inspirację zarówno w obszarze metodologii badania materiałów dydaktycznych, jak i praktycznych sposobów sposobu wprowadzania do szkolnych podręczników treści kształtujących postawy równościowe.
Radio frequency fingerprinting for outdoor user equipment localization
2017
The recent advancements in cellular mobile technology and smart phone usage have opened opportunities for researchers and commercial companies to develop ubiquitous low cost localization systems. Radio frequency (RF) fingerprinting is a popular positioning technique which uses radio signal strength (RSS) values from already existing infrastructures to provide satisfactory user positioning accuracy in indoor and densely built outdoor urban areas where Global Navigation Satellite System (GNSS) signal is poor and hard to reach. However a major requirement for the RF fingerprinting to maintain good localization accuracy is the collection and updating of large training database. The Minimization…
Distance learning training in genetics and genomics testing for Italian health professionals: results of a pre and post-test evaluation
2022
BackgroundProgressive advances in technologies for DNA sequencing and decreasing costs are allowing an easier diffusion of genetic and genomic tests. Physicians’ knowledge and confidence on the topic is often low and not suitable for manage this challenge. Tailored educational programs are required to reach a more and more appropriate use of genetic technologies.MethodsA distance learning course has been created by experts from different Italian medical associations with the support of the Italian Ministry of Health. The course was directed to professional figures involved in prescription and interpretation of genetic tests. A pretest-post-test study design was used to assess knowledge impr…
A Preliminary Analysis of the Importance of Distance, Angle, and Insight When Soccer Referees Make Penalty Decisions
2021
Soccer referees move freely on the pitch to place themselves in the best location for making decisions. While Football Association UK (FA) highlights that a referee should never be more than 20 m away from the playing situation, previous studies have been inconsistent in indicating appropriate distance to a situation for increasing the likelihood of a correct decision. Further, appropriate angle and insight are also likely to influence the correctness of referees' decisions. The aim of this study was to provide an initial investigation of elite referees' positioning in the field (distance, angle, and insight) when making correct and erroneous decisions in potential penalty situations. An ex…
On developing adaptive vocabulary learning game for children with an early language delay
2018
Vocabulary replenishment is an ordinary child development process. Deviations in this process can significantly affect the further progress and perception of the educational material in the school. A hypothesis was proposed that the similarity of words on various factors can influence the child's understanding. To test this hypothesis in this work, we propose the development of AdapTalk game for children. This game is concentrated on learning words, in the context of animals. The game will create the basis for further testing the influence of the semantic similarity of words for the child. This work describes the development background, the basic principles of calculating the semantic simil…
