Latvijas Universitātes publikācijas citējamības datubāzēs (2007-2011)
2012
Sākot ar 2012. gadu Latvijas Universitātei (LU) ir pieejamas divas nozīmīgākās citējamības datubāzes - Web of Science un Scopus, kas ļauj analizēt LU personāla publikāciju citējamību. Publikāciju skaits citējamības datubāzēs ir viens no augstskolas kvalitātes un atpazīstamības rādītājiem. Publikācijas atrašanās citējamības datubāzē raksturo arī tās zinātnisko kvalitāti. Citēšana tiek uzskatīta par publikācijas zinātniskā nozīmīguma rādītāju un citējumi norāda uz autora ieguldījumu zinātnes nozares attīstībā. Pētījumā ir raksturota LU personāla publikāciju un citējumu skaita dinamika pēdējos piecos gados Web of Science un Scopus datubāzēs.
Map of the visibility and search engine positioning of the main Spanish media groups
2020
Este trabajo analiza la visibilidad y posicionamiento en buscadores de los sitios web de los principales grupos de comunicación españoles. Se compara su visibilidad web y su presencia en los resultados de búsqueda de Google a través de programas de análisis SEO y una metodología propia que se ha denominado Índice de Visibilidad Agregada. Se ha realizado un análisis comparativo de los grupos Atresmedia, COPE, Godó, Hearst Magazines, Henneo, Imagina Media Audiovisual, Intereconomía Corporación, Joly, Mediaset España Comunicación, Planeta, Prensa Ibérica, Prisa, Unidad Editorial, Vocento y Zeta. Se ha podido establecer que Unidad Editorial es el grupo con mayor tráfico web proveniente de búsqu…
La Educación Musical en España dentro del currículo obligatorio de Educación Secundaria : estudio comparado entre comunidades autónomas
2020
Despite the fact that there are many studies that identify that the Music Education provides numerous benefits to all those students who study it, the truth is that in Spain there is a regression of its presence in the Compulsory Education as the different educational laws are enacted. If during the LOGSE (1990) both Art and Music Education were compulsory within their respective educational stages, in the last years with the LOMCE (2013) these subjects have become optional. In this way, their presence is at the mercy of the Autonomous Communities. Specifically, this article analyses the current situation of Music within the Compulsory Secondary Education through a comparative study among t…
Web-sovellusten testaaminen Selenium-testaustyökalun avulla
2016
Eräs tapa testata web-sovelluksia on automaattinen testaus, jota tässä tutkielmassa tarkastellaan. Testaaminen on web-sovelluksen elinkaaressa tärkeä osa, sillä websovelluksilta vaaditaan nykyään paljon niin käytettävyyden, turvallisuuden kuin tehokkuudenkin osalta. Tutkielmassa käydään läpi automaattisen testauksen perusperiaatteita ja esitellään web-sovellusten automaattiseen testaukseen käytettävää työkalua nimeltä Selenium. Selenium rakentuu useasta eri komponentista ja tämä tutkielma perehtyy erityisesti näistä kahteen: Selenium IDE-ohjelmointiympäristöön sekä WebDriver-rajapintaan. One way to test web applications is automated testing which this thesis examines. Software testing is an…
Digital recording as a teaching and learning method in the skills laboratory.
2017
Aim and objectives To obtain information on how nursing students react to, think about and learn from digital recording as a learning and teaching method over time. Background Based on the teaching and learning philosophy of the university college, we used digital recording as a tool in our daily sessions in skills laboratory. However, most of the studies referred to in the background review had a duration of from only a few hours to a number of days. We found it valuable to design a study with a duration of two academic semesters. Design A descriptive and interpretative design was used. Method First-year bachelor-level students at the department of nursing participated in the study. Data c…
Effects of feedback on self-efficacy, performance, and choice in an athletic task
1999
Abstract The purpose of the study was to examine the impact of feedback on self-efficacy, performance, and task choice, and the mediating effects of self-efficacy in the feedback-performance and task choice relationships. Participants were 69 Spanish students, 46 males and 23 females, between 18 and 24 years. The experimental paradigm consisted of three sessions. In the first, participants performed on the hurdles. In the second, manipulated feedback referring to the previous performance was provided. Participants then estimated their self-efficacy for a second task which they later performed. In the third session, participants were presented with three tasks involving clearing hurdles of p…
Studying the feasibility of a recommender in a citizen web portal based on user modeling and clustering algorithms
2006
This paper presents a methodology to estimate the future success of a collaborative recommender in a citizen web portal. This methodology consists of four stages, three of them are developed in this study. First of all, a user model, which takes into account some usual characteristics of web data, is developed to produce artificial data sets. These data sets are used to carry out a clustering algorithm comparison in the second stage of our approach. This comparison provides information about the suitability of each algorithm in different scenarios. The benchmarked clustering algorithms are the ones that are most commonly used in the literature: c-Means, Fuzzy c-Means, a set of hierarchical …
Growing Hierarchical Self-organizing Maps and Statistical Distribution Models for Online Detection of Web Attacks
2013
In modern networks, HTTP clients communicate with web servers using request messages. By manipulating these messages attackers can collect confidential information from servers or even corrupt them. In this study, the approach based on anomaly detection is considered to find such attacks. For HTTP queries, feature matrices are obtained by applying an n-gram model, and, by learning on the basis of these matrices, growing hierarchical self-organizing maps are constructed. For HTTP headers, we employ statistical distribution models based on the lengths of header values and relative frequency of symbols. New requests received by the web-server are classified by using the maps and models obtaine…
Web mining based on Growing Hierarchical Self-Organizing Maps: Analysis of a real citizen web portal☆
2008
This work is focused on the usage analysis of a citizen web portal, Infoville XXI (http://www.infoville.es) by means of Self-Organizing Maps (SOM). In this paper, a variant of the classical SOM has been used, the so-called Growing Hierarchical SOM (GHSOM). The GHSOM is able to find an optimal architecture of the SOM in a few iterations. There are also other variants which allow to find an optimal architecture, but they tend to need a long time for training, especially in the case of complex data sets. Another relevant contribution of the paper is the new visualization of the patterns in the hierarchical structure. Results show that GHSOM is a powerful and versatile tool to extract relevant …
A note on validity in law and regulatory systems (position paper)
2012
This is position paper is located at the theoretical crossroads of several projects: CAPER, EU Grant Agreement 261712; CROWDSOURCING DER2012-39492-C02-0, SINTELNET FP7-ICT-2009-C-286380; CONSUMEDIA INNPACTO IPT-2011-1015-430000; CROWD-CRISSCONTROL IPT-2012-0968-390000. The notion of validity fulfils a crucial role in legal theory. The emerging Web 3.0 opens a new landscape where Semantic Web languages, legal ontologies, and the construction of Normative Multiagent Systems are built up to cover new regulatory needs. Conceptual models for complex regulatory systems shape the characteristic features of rules, norms and principles in different ways. This position paper outlines one of such mult…
