Data from: Successive invasion-mediated interspecific hybridizations and population structure in the endangered cichlid Oreochromis mossambicus
2013
Hybridization between invasive and native species accounts among the major and pernicious threats to biodiversity. The Mozambique tilapia Oreochromis mossambicus, a widely used freshwater aquaculture species, is especially imperiled by this phenomenon since it is recognized by the IUCN as an endangered taxon due to genetic admixture with O. niloticus an invasive congeneric species. The Lower Limpopo and the intermittent Changane River (Mozambique) drain large wetlands of potentially great importance for conservation of O. mossambicus, but their populations have remained unstudied until today. Therefore we aimed (1) to estimate the autochthonous diversity and population structure among genet…
On the Use of XML in Medical Imaging Web-Based Applications
2016
The rapid growth of digital technology in medical fields over recent years has increased the need for applications able to manage patient medical records, imaging data, and chart information. Web-based applications are implemented with the purpose to link digital databases, storage and transmission protocols, management of large volumes of data and security concepts, allowing the possibility to read, analyze, and even diagnose remotely from the medical center where the information was acquired. The objective of this paper is to analyze the use of the Extensible Markup Language (XML) language in web-based applications that aid in diagnosis or treatment of patients, considering how this proto…
School of migrant children, an ethnography in an unregistered migrant school in Beijing
2012
This thesis discusses about the challenge of education for migrant children in the rapidly urbanized Chinese society. An ethnographic research was conducted in one of the unregistered migrant schools in Beijing. Through a triangulation of research methods of participatory observation, semi-structured and life history interview, as well as photography, the research, from emic perspectives, analyzes the advantages and disadvantages of the migrant schools in education provision to migrant children, understands the gaps between policy commitments and on-the-ground delivery of public education provision, and raises a few policy recommendations of developing the migrant schools and improving educ…
Neutriinojen ja kvarkkien sekoitusmatriisien välinen yhteys
2012
In this thesis relations between neutrino mixing matrix and quark mixing matrix are studied. The focus of the analysis is on two simple cases. In the first case it is assumed that the left matrix that diagonalizes the mass matrix of charged leptons and the corresponding matrix of down quarks are equal. In the second case it is likewise assumed that the corresponding diagonalizing matrices of neutrinos and up quarks are equal. First, theoretical concepts related to the mixing of quarks and especially to the mixing of neutrinos are presented. These are e.g. fermion mass generation in the Standard Model, Majorana masses of neutrinos and the so-called seesaw mechanism. Regarding experiments, ne…
Regional concentration of university graduates : The role of high school grades and parental background
2020
In this paper, we analyse long-term changes in the regional distribution and migration flows of university graduates in Finland and Sweden. This study is based on detailed longitudinal population register data, including information on high school grades and parental background. We find a distinct pattern of skill divergence across regions in both countries over the last 3 decades. The uneven distribution of human capital has been reinforced by the mobility patterns of university graduates, for whom regional sorting by high school grades and parental background is evident. Our findings indicate that traditional measures of human capital concentration most likely underscore actual regional …
El trastorn de l'espectre autista i les aules de comunicació i llenguatge: coneixements dels futurs mestres, efectivitat de la metodologia TEACCH i a…
2018
L’augment de la prevalença dels xiquets diagnosticats amb trastorn de l’espectre autista (TEA) en els últims anys (Christensen et al., 2016), junt a la promulgació del principi d’inclusió establert a les darreres lleis educatives (LOE, 2006; LOMQE, 2013), ha comportat que l’atenció d’aquests xiquets siga una vertadera necessitat social, sobre la qual el professorat requereix estar preparat. Tot i que tradicionalment no ha estat contemplat als criteris diagnòstics, diversos estudis han evidenciat que gran part dels xiquets amb TEA presenten alteracions en el processament sensorial de la informació (per ex.: Ashburner et al., 2008; Ben-Sasson et al., 2009; Lai et al., 2011; Tomchek et al., 20…

Abbreviaciâ kak sposob slovoobrazovaniâ v russkom âzyke : na osnove tekstov SMI
2017
Tutkin pro gradu-tutkielmassani lyhenteiden käyttöä ja muodostumista massamedian teksteissä. Tarkoituksenani on selvittää, miten lyhenteitä käytetään sekä miten ne muodostuvat uutisteksteissä ja keskustelufoorumeilla. Tutkielmassani keskityn tarkastelemaan nimenomaan lyhenteiden muodostumisen eroja median eri ympäristöissä. Selvitän, onko lyhenteiden käytössä eroja uutisteksteissä ja keskustelufoorumeilla, ja jos on, niin millaisia. Olen asettanut työlleni seuraavanlaiset tutkimuskysymykset: 1) Miten lyhenteet muodostuvat, sekä miten niitä käytetään uutisteksteissä ja keskustelufoorumeilla? Millaisia eroja lyhenteiden käytössä on? 2) Millaisia ovat lyhenteiden käytön ja muodostumisen eritys…
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…
