Språkbadselevers skriftliga kunskaper i svensk grammatik enligt utvecklingsnivåerna av processbarhetsteorin
2016
Tutkielman tarkoituksena oli tarkastella kuudesluokkalaisten kielikylpyoppilaiden ruotsin kieliopin taitoja Manfred Pienemannin prosessoitavuusteorian valossa. Tärkein tutkimuskysymys oli, mille teorian viidestä tasosta oppilaat sijoittuvat. Tutkimuksen materiaalina oli 12 19 oppilaan kirjoittamaa kirjoitelmaa, eli osa kirjoitelmista oli kirjoitettu ryhmässä. Tutkimus oli kvalitatiivinen ja menetelmänä käytettiin teorialähtöistä sisällönanalyysiä. Tulokset osoittivat, että oppilaat sijoittuivat prosessoitavuusteorian neljännelle ja viidennelle tasolle. Parityöskentelystä johtuen tuloksia voidaan tarkastella ennemmin ryhmä- kuin yksilötasolla. Pienestä aineistosta johtuen tuloksia ei myöskää…
Strategisk kommunikasjon i sosiale medier : en studie av NSBs dialogiske kommunikasjon på Facebook
2016
Masteroppgave samfunnskommunikasjon- Universitetet i Agder, 2016 I denne oppgaven undersøkes det hvordan virksomheter kan bruke sosiale medier i sitt arbeid med strategisk kommunikasjon. For å finne ut av dette vil jeg se på hvordan NSB bruker dialogisk kommunikasjon på Facebook for å bygge og vedlikeholde gode relasjoner til sine kunder. Til grunn for oppgaven ligger teorier om sosiale medier, strategisk kommunikasjon og samtaleanalyse. Studien er delt inn i to analysedeler: én tekstanalyse og én kontekstanalyse. I tekstanalysen rettes fokuset mot hvordan NSB kommuniserer på Facebook. Analysen innledes med et kvantitativ kartleggende studie som skal gi en oversikt over NSBs Facebookside. D…
Past, present, and future of green product innovation
2021
Firms are under constant pressure from various governmental and nongovernmental agencies to switch from conventional environmentally polluting products to green product innovations (GPIs). However, the relevant research pertaining to GPI has been published in a diverse set of journals that vary in their scope and readership and, therefore, the scholarly contribution to the topic remains largely fragmented. This study has utilised a systematic literature review approach to examine the literary corpus on GPI to paint a holistic picture of its different aspects. The content and thematic analysis of 85 studies resulted in the extraction of seven key research themes: organisational capabilities,…
Durability is improved by both low and high intensity endurance training
2023
Introduction: This is one of the first intervention studies to examine how low- (LIT) and high-intensity endurance training (HIT) affect durability, defined as ‘time of onset and magnitude of deterioration in physiological-profiling characteristics over time during prolonged exercise’.Methods: Sedentary and recreationally active men (n = 16) and women (n = 19) completed either LIT (average weekly training time 6.8 ± 0.7 h) or HIT (1.6 ± 0.2 h) cycling for 10 weeks. Durability was analyzed before and after the training period from three factors during 3-h cycling at 48% of pretraining maximal oxygen uptake (VO2max): 1) by the magnitude and 2) onset of drifts (i.e. gradual change in energy ex…
A Network-Based Framework for Mobile Threat Detection
2018
Mobile malware attacks increased three folds in the past few years and continued to expand with the growing number of mobile users. Adversary uses a variety of evasion techniques to avoid detection by traditional systems, which increase the diversity of malicious applications. Thus, there is a need for an intelligent system that copes with this issue. This paper proposes a machine learning (ML) based framework to counter rapid evolution of mobile threats. This model is based on flow-based features, that will work on the network side. This model is designed with adversarial input in mind. The model uses 40 timebased network flow features, extracted from the real-time traffic of malicious and…
DOBRO : a prediction error correcting robot under drifts
2016
We propose DOBRO, a light online learning module, which is equipped with a smart correction policy helping making decision to correct or not the given prediction depending on how likely the correction will lead to a better prediction performance. DOBRO is a standalone module requiring nothing more than a time series of prediction errors and it is flexible to be integrated into any black-box model to improve its performance under drifts. We performed evaluation in a real-world application with bus arrival time prediction problem. The obtained results show that DOBRO improved prediction performance significantly meanwhile it did not hurt the accuracy when drift does not happen.
Dabas aizsardzības telpu veidošanās Ķemeru Nacionālajā parkā 20. – 21.gs.
2022
Bakalaura darbā “Dabas aizsardzības telpu veidošanās Ķemeru Nacionālajā parkā 20.-21. gs.” tika noskaidrotas dabas aizsardzības teritoriju veidošanās īpatnības Ķemeru Nacionālajā parkā 20.-21. gs. Darbā tika aplūkotas tādas tēmas kā dabas aizsardzības ģeogrāfija, N. Trifta telpu koncepts, dabas aizsardzības ideju attīstība pasaulē un Latvijā. Pētījumā ir interpretētas dabas aizsardzības teritorijas, kā empīriskā, plūsmu, attēlu un vietas telpa. Balstoties uz dažādu ar dabas aizsardzību saistīto avotu analīzi, ir izveidota un analizēta ĶNP veidošanās laiktelpas reprezentācija: notikumu un pasākumu hronoloģiskā laika skala un teritoriālās attīstības kartes. Rezultātos tika analizēti Ķemeru Na…
