Energy Drink Consumption Among Finnish Adolescents: Prevalence, Associated Background Factors, Individual Resources, and Family Factors.
2020
Objectives: Energy drink consumption among adolescents has become a notable global phenomenon, and has been associated with numerous negative health outcomes. In order to understand the popularity of energy drinks among adolescents, and to target interventions, it is important to identify the determinants underpinning consumption. Methods: The nationally representative data (cross-sectional) were drawn from the Health Behaviour in School-aged Children (HBSC) surveys, conducted in 2014 and 2018, each comprising 13- and 15-year-old Finnish adolescents (n = 7405). Results: Weekly energy drink consumption increased among Finnish adolescents between 2014 (18.2%) and 2018 (24.4%), especially amon…
Motivational sources of practical nursing students at risk of dropping out from vocational education and training
2019
The aim of this study was to contribute to the understanding of the reasons for low or high academic motivation among practical nursing students at risk of dropping out from vocational education and training. The research data consisted of semi-structured interviews with 14 Finnish students, which were analysed by qualitative content analysis. The analysis identified six motivational sources. Two of these sources – Responsible agency and Completing out of necessity – were related to engagement in studying, whereas two other sources – Exhaustion from learning challenges and Tight-roping between competing responsibilities – were related to disengagement from studying. Emotional drive and Soci…
Equivalence of viscosity and weak solutions for the normalized $p(x)$-Laplacian
2018
We show that viscosity solutions to the normalized $p(x)$-Laplace equation coincide with distributional weak solutions to the strong $p(x)$-Laplace equation when $p$ is Lipschitz and $\inf p>1$. This yields $C^{1,\alpha}$ regularity for the viscosity solutions of the normalized $p(x)$-Laplace equation. As an additional application, we prove a Rad\'o-type removability theorem.
On the second-order regularity of solutions to the parabolic p-Laplace equation
2022
AbstractIn this paper, we study the second-order Sobolev regularity of solutions to the parabolic p-Laplace equation. For any p-parabolic function u, we show that $$D(\left| Du\right| ^{\frac{p-2+s}{2}}Du)$$ D ( D u p - 2 + s 2 D u ) exists as a function and belongs to $$L^{2}_{\text {loc}}$$ L loc 2 with $$s>-1$$ s > - 1 and $$1<p<\infty $$ 1 < p < ∞ . The range of s is sharp.
Antibiotiku punkta prevalences pētījums bērnu slimnīcā
2020
Antibiotikas ir bieži izrakstītas recepšu zāles gan pieaugušo, gan bērnu populācijā. Nereti antibiotikas nozīmē nepamatoti, tāpēc rodas bažas par pārmērīgu antibiotiku lietošanu un rezistences attīstību. Antibiotikas bērniem tiek izrakstītas gan bakteriālo infekciju ārstēšanai, gan arī ķirurģiskās profilakses nolūkos. Bakalaura darba ietvaros VSIA “Bērnu Klīniskā Universitātes slimnīca” tika veikts punkta prevalences pētījums pēc antibiotiku rezistences un zāļu izrakstīšanas Eiropas bērniem (ARPEC) modeļa. Darba mērķis: Noskaidrot bērnu un jaundzimušo antibakteriālo zāļu izrakstīšanas tendences VSIA “Bērnu Klīniskā Universitātes slimnīca”, lai rastu ieteikumus antibiotiku lietošanas un kval…
Ontological diversity in gaming disorder measurement: a nationally representative registered report
2022
Gaming-related health problems have been researched since the 1980s with numerous different ontologies as reference systems, from self-assessed ‘game addiction’ to ‘pathological gambling’ (in the Diagnostic and Statistical Manual of Mental Disorders [DSM]-IV), ‘internet gaming disorder’ (in the third section of the DSM-5) and most recently ‘gaming disorder’ (in the International Classification of Diseases [ICD]-11). Our goal was to investigate how screening instruments that derive from different ontologies differ in identifying associated problem groups. By using four central screening instruments, each representing a different ontological basis, we hypothesized differences and similarities…
Problematising the equivalence of the test results of performance-based critical thinking tests for undergraduate students
2015
Abstract This article compares the test results of two different performance-based assessments of critical thinking: a constructed-response task from the Collegiate Learning Assessment (CLA) and a multiple-choice questionnaire (MCQ). These tests ostensibly measure the same critical thinking skills, such as analysing, interpreting and evaluating information and problem solving. The study utilised a mixed-method approach to explore the differences in students’ ( n = 330) test scores. The results showed that the correspondence between the CLA and the MCQ was fully comparable in 45.5% of the students’ test performances. Ten percent of the students had completely opposite test results. Explanat…
Apikālā periodontīta sastopamības biežums un endodontikās ārstēšanas kvalitāte pieaugušo izvēlētā populācijā Latvijā
2022
Apikālais periodontīts (AP) ir izplatīta hroniska iekaisuma slimība, kas izpaužas kā dinamiska organisma aizsargreakcija pret mikrobu infekciju zobu sakņu kanālu sistēmā. Pētījumi liecina, ka AP ir plaši izplatīts pieaugušajiem - vismaz viens zobs ar AP ir 27 - 80% pieaugušo (Kirkevang & Vaeth, 2019). AP ir tieša saistība ar sakņu kanālu ārstēšanas kvalitāti – nekvalitatīva ārstēšana tiek saistīta ar palielinātu AP izplatību (Chala et al., 2011; Meirinhos et al., 2020). Darba mērķis bija izpētīt apikālā periodontīta izplatību un endodontiskās ārstēšanas biežumu un kvalitāti izvēlētā Latvijas pieaugušo populācijā.
The Fuzzy Concept of Idiom and What It Might Mean for Bilingual Dictionaries
2019
Linguistic categories were developed as tools for describing language systems and making them easier to learn. However, like many theoretical concepts and systems, they do not fully represent the real world and, in some cases, seek to imprison linguistic units within a well-ordered system – a procrustean bed as it were. Besides, although the most general categories are universal, the lower-ranking ones are often language-specific. Idiom (or phraseologism) is a very unclear linguistic concept, subject to never-ending debate. However, a strict adherence to categorisation is observable in practical bilingual lexicography and phraseography. This may lead to unwanted compartmentalisation and a…
Embeddings of Danielewski hypersurfaces
2008
In this thesis, we study a class of hypersurfaces in $\mathbb{C}^3$, called \emph{Danielewski hypersurfaces}. This means hypersurfaces $X_{Q,n}$ defined by an equation of the form $x^ny=Q(x,z)$ with $n\in\mathbb{N}_{\geq1}$ and $\deg_z(Q(x,z))\geq2$. We give their complete classification, up to isomorphism, and up to equivalence via an automorphism of $\mathbb{C}^3$. In order to do that, we introduce the notion of standard form and show that every Danielewski hypersurface is isomorphic (by an algorithmic procedure) to a Danielewski hypersurface in standard form. This terminology is relevant since every isomorphism between two standard forms can be extended to an automorphism of the ambiant …
