Il coinvolgimento dei giovani negli incidenti stradali: il trattamento dei dati attraverso un Web-GIS
2009
2021
Bulk stable nitrogen isotope values of the carbonate-bound organic matrix in bivalve shells (δ15NCBOM) are increasingly used to assess past food web dynamics, track anthropogenic nitrogen pollution and reconstruct hydrographic changes. However, it remains unresolved if the δ15NCBOM values are also affected by directed ontogenetic trends which can bias ecological and environmental interpretations. This very aspect is tested here with modern and fossil specimens of the long-lived ocean quahog, Arctica islandica, collected from different sites and water depths in the NE Atlantic Ocean. As demonstrated, δ15NCBOM values from the long chronologies show a general decrease through lifetime by −0.00…
Generalist invasion in a complex lake food web
2023
Invasive species constitute a threat not only to native populations but also to the structure and functioning of entire food webs. Despite being considered as a global problem, only a small number of studies have quantitatively predicted the food web-level consequences of invasions. Here, we use an allometric trophic network model parameterized using empirical data on species body masses and feeding interactions to predict the effects of a possible invasion of Amur sleeper (Perccottus glenii), on a well-studied lake ecosystem. We show that the modeled establishment of Amur sleeper decreased the biomasses o ftop predator fishes by about 10%–19%. These reductions were largely explained by inc…
Www-sovelluskehitys Vaadin-kehyksellä
2012
Tämä tutkielma käsittelee suomalaista WWW-sovelluskehystä Vaadinta. Se on palvelinpohjainen Java-kehys rikkaiden WWW-sovellusten kehittämiseen. Tutkielmassa esitellään myös WWW-kehyksiä yleisesti sekä WWW-kehysten yleensä käyttämä MVC-arkkitehtuuri. Lisäksi esitellään myös Vaatimen käyttämät tekniikat: AJAX, UIDL, JSON ja DOM sekä kuinka Vaadin niitä käyttää. Vaatimesta käydään läpi käyttöliittymäkomponentit, tapahtumien käsittely, tietomalli ja ulkoasun muokkaus. Lopuksi esitellään Vaatimen käyttöä esimerkkisovelluksen avulla.
Beyond Remittances
2016
Young, tertiary-educated emigrants see themselves, and are seen by their home country's government, as agents of economic and social change, especially if they can be incentivized to return home. In this paper we examine the barriers that prevent this positive impact from being fully realized, taking the case of Latvia, formerly part of the Soviet Union but since 2004 a member state of the European Union. We build our analysis on data from an online questionnaire (N = 307) and from narrative interviews (N = 30) with foreign-educated Latvian students and graduates. In moving beyond remittances, we examine knowledge transfer to the home country as a form of “social remittance” and break down …
Designing and Evaluating Online Language Learning Materials for Higher Education
2011
Nowadays, finding, choosing and developing or adapting materials is a very important component of education as well as a key element for the success of the whole learning process. A language teacher is also a materials developer and the materials development process should aim at ensuring that local needs and wants do not dictate decisions and that important learning principles are not forgotten. In the case of materials for Computer-Assisted Language Learning (CALL), a very thorough and pedagogically-sound set of guidelines should be followed prior to the design of the materials. Following that, a careful evaluation should take place so as to guarantee that those guidelines have been follo…

HTML5 tablet uutissovelluksen suunnittelu ja toteutus
2013
Keskipohjanmaa-lehdestä haluttiin toteuttaa web-pohjainen, HTML5:tä hyödyntävä tablet-uutissovellus Keski-Pohjanmaan Kirjapaino Oyj:lle. Työssä tut- kittiin uusimpia web-teknologioita, kannettavia laitteita, web-sovelluksen tekemis- tä ja tablet-sovelluksen luomista sanomalehdestä. Työn aikana toteutettiin kolme prototyyppiä ja kaksi virallista tablet-sovellusversiota. Ensimmäisessä virallisessa versiossa rakenne ja data olivat yhdessä sekä osa sovelluslogiikasta oli palvelimen koodissa. Toisessa versiossa data ja rakenne olivat erillään ja sovelluslogiikka oli tehty Javascriptillä. Tehdessä web-sovellusta tablet-laitteille selvisi, että on huomioi- tava suorituskyky ja Internet-selainten e…
Efficiency Analysis Of Resource Request Patterns In Classification Of Web Robots And Humans
2018
The paper deals with the problem of classification of Web traffic generated by robots and humans on e-commerce websites. Due to the still growing proliferation and specialization of bots, a large body of research into characterization and recognition of their traffic has been conducted so far. In particular, some approaches to classify bot and human sessions on websites have been proposed in the literature. In this paper we verify and discuss the efficiency of such recently proposed approach, which uses differences in resource request patterns of bots and humans. We reconstructed Web sessions from actual HTTP log data for three different e-commerce sites, varying in the traffic intensity an…
