Media literacy of secondary school students: evaluation of manipulative language and digital tools in social media Instagram content during the Covid…
2020
Maģistra darba mērķis ir izpētīt, kādi manipulatīvie valodas, informācijas un digitālie līdzekļi lietoti sociālā medija Instagram Latvijas jauniešu influenceru ierakstos, un noskaidrot, vai un kurus no tiem vidusskolēni spēj identificēt. Teorētiskajā daļā ietverti medijpratības, mediju izglītības aspekti, dezinformācija un manipulatīvo līdzekļu lietojums pārliecināšanā, kā arī izpētīti sociālo mediju un digitālā satura veidošanas nosacījumi. Darbā izmantota kvantitatīvā un kvalitatīvā kontentanalīze influenceru ierakstu analīzei un tiešsaistes aptauja vidusskolēnu medijpratības noteikšanai. Secināts, ka influenceri ierakstos iesaista valodas manipulatīvos līdzekļus, kurus atpazīst arī vidus…

Terapeuttisen harjoittelun vaikuttavuus päänsäryn hoidossa : systemaattinen katsaus ja meta-analyysi satunnaistetuista, kontrolloiduista tutkimuksista
2014
Tausta: Päänsärky on yksi yleisimmistä neurologisista oireista, sillä lähes kaikilla on jossain vaiheessa elämäänsä päänsärkyä. Tämän vuoksi on tärkeää selvittää myös ei-lääkkeellisten hoitomuotojen käyttöä päänsäryn hoidossa. Tämän systemaattisen katsauksen ja meta-analyysin tarkoituksena oli tutkia terapeuttisen harjoittelun vaikutusta päänsärkyyn. Tutkimusmenetelmä: Tähän analyysin haettiin satunnaistettuja, kontrolloituja tutkimuksia seuraavista tietokannoista vuosilta 1980 - 2013 syyskuu; PubMed (Medline), The Cochrane Central Register of controlled Trials, SPORTDiscus, Cinahl ja The Physiotherapy evidence based database (PEDro). Katsaukseen hyväksyttiin tutkimukset, jotka käsittelivät…
On the volumetric response of a compacted clay subjected to wetting and drying cycles
2009
Experimental evidence on the volumetric response of a compacted clay was collected in controlled suction oedometric tests, with the aim to assess the volumetric response of this soil when subjected to wetting and drying cycles. The overall soil behaviour seems mainly to depend on the double structural arrangement observed in the compacted specimens. Selected results are presented and discussed focusing on the influence of the stress history on the volumetric response. Test results are simulated by a double-structure suction-dependent elasto-plastic constitutive model, in which the mechanical response is related to micro and macrostructural deformations and their mutual interactions. The pro…
Design and realization of a DC/DC converter with a partially saturated inductor
2017
DC/DC converters, in some types of applications such as portable equipments, can require more space than it is actually available. The inductor is typically the most bulky element and the possibility to reduce its size can save up to 50% of the converter volume and area [1][2], thus increasing the power density. This reduction, however, comes with nonlinear effects caused by the saturation of the ferromagnetic core. An appropriate modelling of the inductor and of the converter circuit is needed for guaranteeing a good output power quality (Fig. 1). A Boost converter with an inductor in the partially saturated roll-off operating zone was designed and realized to study the behaviour of DC/DC …
Non-Linear Inductor Models Comparison for Switched-Mode Power Supplies Applications
2022
The use of non-linear power inductors, intended as devices exploited up to a current at which the inductance is halved, is of great interest in switched-mode power supplies (SMPSs). Indeed, it allows the use of lighter and cheaper inductors improving the power density. On the other hand, the analysis of SMPSs equipped with non-linear inductors requires appropriate modeling of the inductor reproducing the inductance versus current. This paper compares two main analytical models proposed in the literature: the former is based on a polynomial, and the latter exploits the arctangent function to reproduce the non-linearity of the inductance. Performance is compared by considering the effort of r…
Readers’ Theater Projects for Special Education : A Randomized Controlled Study
2022
A randomized controlled trial was conducted to study the effectiveness of two readers’ theater (RT) programs in promoting reading skills and motivation of dysfluent readers in Grades 3–4. One program (RT Goal) included a goal of preparing a performance for an audience (n = 50), while another program (RT Practice) did not include such a goal (n = 49). A group of dysfluent readers receiving traditional oral reading intervention (Control group; n = 59) and a group of classroom peers (Mainstream group; n = 159) served as controls. The results indicate that both RT groups and the Control group developed at a higher rate in oral reading speed during the intervention period than the Mainstream gro…
Exercise for bone and cartilage in postmenopausal women with mild knee osteoarthritis
2016
The purpose of this study was to investigate the effects of high-impact exercise on bone mineral mass and strength, and on knee cartilage composition in postmenopausal women with mild knee osteoarthritis (OA). In addition, the association between knee OA and femoral neck bone structural characteristics in women with mild knee radiographic OA and those without radiographic knee OA was studied. Also, the reproducibility of measuring human knee joint cartilage by the delayed gadolinium-enhanced MRI (dGEMRIC) technique was determined in healthy asymptomatic subjects. Data from a 12-month randomized controlled trial (RCT) was used to assess the effects of exercise on bones and cartilages. The tr…
