Extending the Technology Acceptance Model with Personal Innovativeness and Technology Readiness : A Comparison of Three Models
2016
This study concentrates on the role of personal traits in technology acceptance by comparing which of the two personal trait constructs commonly used in IS research, personal innovativeness in the domain of information technology (PIIT) or technology readiness index (TRI), performs better in terms of promoting the explanatory power of the technology acceptance model (TAM). The comparisons are conducted in the case context of online services offered by electric suppliers, and the study is based on the data collected from 1,176 consumers through an online survey and analysed by using structural equation modelling (SEM). The findings of the study show that the inclusion of both PIIT and TRI in…
L'espace de liberté comme mesure synthétique du développement territorial durable
2011
By discussing the concept of development itself, authors propose two synthetic indexes relying on estimation of potential: Development Space Value and Development Space Creation Under the weak hypothesis that any successful development improves future possibilities, changes in potential are a good development measure. In their path, authors show how development space is tied with freedom: a shrink in it results mechanically in indexes fall. So, "sustainable" and "economic" become two sides of same piece rather than enemies. Reliable in simulations, the approach is to be tested in real conditions, to verify full data availability and to secure calculating methods.
Challenges and Opportunities of English Grammar Acquisition by Distance at the Tertiary Level
2021
Distance learning introduced in almost all educational establishments in spring 2020 has raised interest among researchers how to deal with it in a more productive way. Thus, the goal of the research was to find out undergraduates’ views on distance learning of English grammar and the use of online revision materials in developing students’ independent study skills at a tertiary institution in Latvia. the research tool was a questionnaire consisting of open-ended and closed questions. Twenty-three students answered the survey questions. the research results indicate that studying by distance is preferred because it allows the students to choose the study time and place, to develop their tim…
Decompressive Craniectomy Improves QTc Interval in Traumatic Brain Injury Patients
2020
Background: Traumatic brain injury (TBI) is commonly associated with cardiac dysfunction, which may be reflected by abnormal electrocardiograms (ECG) and/or contractility. TBI-related cardiac disorders depend on the type of cerebral injury, the region of brain damage and the severity of the intracranial hypertension. Decompressive craniectomy (DC) is commonly used to reduce intra-cranial hypertension (ICH). Although DC decreases ICH rapidly, its effect on ECG has not been systematically studied. The aim of this study was to analyze the changes in ECG in patients undergoing DC. Methods: Adult patients without previously known cardiac diseases treated for isolated TBI with DC were studied. EC…
Improving statistical classification methods and ecological status assessment for river macroinvertebrates
2016
Aquatic ecosystems are facing a growing number of human-induced stressors and the need to implement more biomonitoring to assess the ecological status of water bodies is eminent. This dissertation aims at providing tools to reduce the costs and improve the accuracy of freshwater benthic macroinvertebrate biomonitoring. To improve the cost-e ciency, we consider automated classi cation and develop a novel classi er suitable for complex macroinvertebrate image data. To enhance the accuracy of macroinvertebrate biomonitoring, we study the statistical properties of the Percent Model A nity index crucial to current Finnish biomonitoring and the factors a ecting these statistics. Finally, we perfo…
Distorsioni nel ricordo della spesa dei turisti: alcune evidenze empiriche
2012
The paper presents some remarks about the distortion of survey data that occurs when tourists are asked to recall the amount of their expenditure for the holiday. The difference between the concepts of perceived expenditure and reminded expenditure is stressed through a review of the relevant literature. An econometric analysis of PRIN 2007 survey data is then presented, with the aim of estimating the personal characteristics of the respondents that are most likely to do errors in remembering their expenditure.
L’efficacité de la communication pour la marque de destination urbaine. Représentations de touristes et de résidents
2019
Face à la concurrence, l’enjeu des destinations consiste à se différencier en développant une identité spécifique. La communication touristique joue alors un rôle capital dans la formation de l’image touristique de la destination. Toutefois, la multiplication des campagnes de communication des différentes strates territoriales ainsi que la couverture médiatique des divers événements peuvent brouiller l’image des destinations. Les recherches universitaires dans ce domaine étant peu nombreuses, il importe d’étudier l’efficacité de la communication des différentes strates territoriales envers une destination urbaine sous l’éclairage de la théorie des représentations sociales. À partir d’une co…
Weight Reduction Behaviors Among European Adolescents : Changes From 2001/2002 to 2017/2018
2020
Purpose The purpose of this study was to analyze changes in the prevalence of weight reduction behaviors (WRBs) among European adolescents from 26 countries between 2001/2002 and 2017/2018. The impact of the perception of body weight on WLB was also analyzed, with particular attention being paid to overestimation. Methods The data of 639,194 European adolescents aged 11, 13, and 15 years who participated in the Health Behaviour in School-aged Children survey were analyzed. Age-standardized prevalence rates of WRB were estimated separately by survey round and gender for each country, using the overall 2017/2018 Health Behaviour in School-aged Children study population as the standard. Multiv…
Makrofītu kā bioloģiskās kvalitātes indikatoru vērtējums Latvijas-Lietuvas pārrobežu upju baseinos
2016
Upena-Rasuma I. 2016. Maģistra darbs. Rīga, Latvijas Universitāte, 70 lpp. Maģistra darba mērķis ir makrofītu kā ekoloģiskās kvalitātes indikatoru izmantošanas iespēju izvērtējums Lielupes un Ventas baseinu upju posmos teorijā un praksē. Darbā veikti upju veģetācijas pētījumi, apsekojot 40 upju posmus Ventas un Lielupes baseinu vidēji lielās upēs, raksturotas Latvijā un Lietuvā izmantotās makrofītu pētījumu metodes un sugu trofijas indeksi, analizētas to izmantošanas iespējas un ticamības līmenis, priekšrocības un trūkumi teorijā un praksē, kā arī izvērtēta makrofītu loma Ūdens struktūrdirektīvas ietvaros. Rezultātu daļā sniegts ekoloģiskās kvalitātes novērtējuma izvērtējums, kā arī ieteiku…
Makrofītu sugu sastāva un sastopamības mainība dabiskos un regulētos upju posmos: Aģes upes piemērs
2015
Bakalaura darba mērķis ir noskaidrot makrofītu sugu sastāva un sastopamības mainību dabiskos un regulētos Aģes upes posmos. Darbā veikti upes veģetācijas pētījumi 10 Aģes posmos, no kuriem 5 posmi ir regulēti, bet 5 dabiski; novērtēta upes posmu ekoloģiskā kvalitāte, izmantojot trofijas un sugu daudzveidības indeksus, kā arī noteikti makrofītu augšanu ietekmējošie vides faktori. Iegūtie rezultāti parāda, ka Aģes regulētajos posmos ūdens ekoloģiskā kvalitāte un makrofītu sugu daudzveidība ir zemāka salīdzinājumā ar upes dabiskajiem posmiem.
