Populārās Latvijas personas Instagram vietnē kā viedokļa līderi kosmētikas un modes preču segmentā Latvijas patērētāju starpā 2016.-2017. gadā

2018

Maģistra darba mērķis ir izpētīt sociālajā tīklā Instagram populāro Latvijas iedzīvotāju auditorijas izcelsmi un aktivitāti; noteikt, vai sociālajā tīklā Instagram Latvijas ietekmētāji ir bijuši viedokļu līderi Latvijas iedzīvotājiem vecumā no 18 līdz 35 gadiem modes preču segmentā 2016.-2017.gadā; noteikt faktorus, kas ļauj identificēt un izvērtēt sociālo tīklu ietekmētājus kosmētikas līdzekļu un apģērbu jautājumos. Darbā aplūkotās tādas tēmas kā patēriņa kultūra, demonstratīvs patēriņš, etalongrupas, viedokļu līderi, komunikācija no mutes mutē, sociālo tīklu ietekmētāji un to atlases un novērtēšanas paņēmieni. Tika izmantotas trīs pētījuma metodes – kontentanalīze, daļēji strukturētās int…

Development of microfluidics for sorting of carbon nanotubes

2018

Sorting of carbon nanotubes by their chirality is the current bottleneck in the way to their broad employment based on their exceptional electronic and optical properties. Despite the extensive effort, there is no known method, which would result in really pure chirality ensembles. Previously reported sorting protocols result in enrichment rather than in sorting, alter electronic structure, and suffer from low yield. This is mostly due to the statistical approach, where the nanotubes with mixed chiralities are treated as a set. In this thesis, we propose a new sorting technique based on nanotube-by-nanotube compartmelization, characterization, and sorting in a continuously running droplet-b…

Adaptation to stressful environments : invasion success of the Colorado potato beetle (Leptinotarsa decemlineata)

2018

Biological invasions, specifically human-induced dispersals, are one of the major threats to our biodiversity and are predicted to increase. Invasive pests provide an opportunity to study whether adaptation to human-induced environments could promote invasions to other human-induced environments. One major anthropogenic selection pressure is created by pesticides, and pests can be exposed to various pesticides in their native, as well as introduced, ranges. I investigated whether exposure to anthropogenic selection (i.e. insecticides and herbicides) and exposure to multiple anthropogenic stressors selects for higher stress tolerance. I also tested whether parental prolonged diapause or inse…

Literacy Skill Development of Children With Familial Risk for Dyslexia Through Grades 2, 3, and 8

2015

This study followed the development of reading speed, reading accuracy, and spelling in transparent Finnish orthography through Grades 2, 3, and 8. We compared two groups of children with familial risk for dyslexia, with or without dyslexia in Grade 2 (Dys_FR, n = 35 and NoDys_FR, n = 66) to a group of children without familial risk and dyslexia (Controls, n = 72). The Dys_FR group showed persisting deficiency especially in reading speed, and, to a minor extent, in reading and spelling accuracy. The Dys_FR children, contrary to the other two groups, relied heavily on letter-by-letter decoding in Grades 2 and 3. In children not fulfilling the criteria for dyslexia in Grade 2, the familial ri…

Tooth replacement rates in early chondrichthyans: a qualitative approach

2009

The continuous replacement of teeth throughout their lifetime is a common characteristic of most chondrichthyans. This process was already present in the earliest representatives of the group. It has been well established that different species of extant sharks show rapid tooth replacement rates; however, some authors have suggested that in early chondrichthyans this rate might have been much slower. Here we present a qualitative approach to analyse tooth replacement rates in the Early Devonian shark Leonodus carlsi, the earliest tooth-bearing shark known to date. For this, we have examined 1,103 isolated teeth from Celtiberia, Spain. Our study provides strong evidences of an extremely slow…

Estudio longitudinal del impacto de la violencia de pareja sobre la salud mental y el sistema endocrino de las mujeres

2012

Está ampliamente reconocido que la violencia de pareja tiene un elevado impacto sobre la salud integral de las mujeres. En este sentido, resulta necesario investigar tal impacto a lo largo del tiempo y evaluar qué factores contribuyen a la recuperación o deterioro de la salud. Los objetivos de esta Tesis fueron, en primer lugar, evaluar la evolución de la salud mental, principalmente: sintomatología depresiva, ansiedad, trastorno de estrés postraumático (PTSD) y suicidio, y la evolución del impacto sobre el sistema endocrino, concretamente el funcionamiento de las hormonas cortisol y dehidroepiandrosterona (DHEA) a lo largo de un periodo de tres años, y en segundo lugar, estudiar qué factor…
