Machine Learning Methods for One-Session Ahead Prediction of Accesses to Page Categories
2004
This paper presents a comparison among several well-known machine learning techniques when they are used to carry out a one-session ahead prediction of page categories. We use records belonging to 18 different categories accessed by users on the citizen web portal Infoville XXI. Our first approach is focused on predicting the frequency of accesses (normalized to the unity) corresponding to the user’s next session. We have utilized Associative Memories (AMs), Classification and Regression Trees (CARTs), Multilayer Perceptrons (MLPs), and Support Vector Machines (SVMs). The Success Ratio (SR) averaged over all services is higher than 80% using any of these techniques. Nevertheless, given the …
The effectiveness of leadership development in the military context from a gender viewpoint
2021
In this case study, leadership development is investigated from the viewpoint of women in a military context. In particular, the effectiveness of a leadership development program in a specific context, namely the Finnish Defence Forces, is explored. The program being studied is unique because it is concerned with developing volunteers, not professional soldiers. A longitudinal, interview-based study of the topic was conducted with women who had participated in the program. The data consists of 45 open-ended interviews with 15 women. Each woman was interviewed three times: at the beginning, in the middle and at the end of the program. Content analysis was used to analyse the data. The result…
Motivational sources of practical nursing students at risk of dropping out from vocational education and training
2019
The aim of this study was to contribute to the understanding of the reasons for low or high academic motivation among practical nursing students at risk of dropping out from vocational education and training. The research data consisted of semi-structured interviews with 14 Finnish students, which were analysed by qualitative content analysis. The analysis identified six motivational sources. Two of these sources – Responsible agency and Completing out of necessity – were related to engagement in studying, whereas two other sources – Exhaustion from learning challenges and Tight-roping between competing responsibilities – were related to disengagement from studying. Emotional drive and Soci…
Comparison of Crop Trait Retrieval Strategies Using UAV-Based VNIR Hyperspectral Imaging.
2021
Hyperspectral cameras onboard unmanned aerial vehicles (UAVs) have recently emerged for monitoring crop traits at the sub-field scale. Different physical, statistical, and hybrid methods for crop trait retrieval have been developed. However, spectra collected from UAVs can be confounded by various issues, including illumination variation throughout the crop growing season, the effect of which on the retrieval performance is not well understood at present. In this study, four retrieval methods are compared, in terms of retrieving the leaf area index (LAI), fractional vegetation cover (fCover), and canopy chlorophyll content (CCC) of potato plants over an agricultural field for six dates duri…
Effects of tilling methods on soil penetration resistance, organic carbon and water stable aggregates in a vineyard of semiarid Mediterranean environ…
2018
Tillage, especially in semiarid Mediterranean environment, enhances the mineralization process of soil organic matter (SOM) and, in turn, decreases aggregate stability. Furthermore, continuous tillage leads to the formation of plough pan beneath the tilled layer. In the present study, we investigated the effect of an innovative self-propelled machine (spading machine, SM) for shallow tillage on SOM, water stable aggregates (WSA) and soil penetration resistance (PR). Such effects were compared to those of chisel plough (CP), rotary tiller (RT) and no tillage (NT). Each tilling method was applied up to a depth of 15 cm, whereas in NT only a brush cutter was used for weed control. Soil analyse…
Crossing Borders: An Online Interdisciplinary Course in Health Informatics for Students From Two Countries.
2017
A cross-countries and interprofessional novel approach for delivering an international interdisciplinary graduate health informatics course online is presented. Included in this discussion are the challenges, lessons learned, and pedagogical recommendations from the experiences of teaching the course. Four professors from three different fields and from three universities collaborated in offering an international health informatics course for an interdisciplinary group of 18 US and seven Norwegian students. Highly motivated students and professors, an online technology infrastructure that supported asynchronously communication and course delivery, the ability to adapt the curriculum to meet…
The integration of content and language in students’ task answer production in the bilingual classroom
2016
The notion of content and language integration has recently become a key topic of inquiry in research on content and language integrated learning and other kinds of bilingual educational programmes. Understanding what integration is and how it happens is of fundamental importance not only for researchers interested in gauging the possibilities and limitations of bilingual programmes, but also for practitioners seeking optimal ways to support student development. This study investigates integration as it takes place in the context of collaborative writing in the classroom. Drawing on conversation analytic methodology, text production is investigated as a social and sequentially evolving phen…
From interdependence to agency
2011
Maahanmuuttajien määrä Suomessa on kasvanut räjähdysmäisesti sitten 1990-luvun. Muutos väestörakenteessa vaikuttaa myös suomalaisten koulujen arkeen ja opettajien työhön, mutta tutkimusta maahanmuuttajista erityisesti kieliaineiden oppijina on vähän. Tämän tutkimuksen tarkoituksena olikin selvittää millainen maahanmuuttajan kielellinen ympäristö Suomessa on ja erityisesti sitä millainen vaikutus sillä on kielten oppimiseen. Tutkimus tarkastelee maahanmuuttajia toiminnan teorian valossa, ja vastauksia haettiin seuraaviin kysymyksiin: 1) miten maahanmuuttajaoppijat käsitteellistävät itsensä englannin ja suomen kielten oppijina, 2) minkälaisia välittyneisyyden keinoja he käyttävät englannin ja…
Imagen social de la prostitución en los medios de comunicación escritos en la ciudad de Valencia: análisis del diario Las Provincias
2014
El presente artículo es el resultado de una investigación realizada a partir del análisis de contenido del medio de comunicación escrito Las Provincias, con el objetivo de conocer y analizar la imagen social que transmiten los medios de comunicación escritos sobre la prostitución de Valencia. Se demuestra que la imagen que transmiten los medios de comunicación escritos ideológicamente conservadores, como es el periódico Las Provincias, determinan la formación de la opinión pública, hecho que favorecerá la producción, la reproducción y perpetuación de estereotipos sobre el ejercicio de la prostitución. This article is the result of a piece of research based on analysing the content of “Las P…
Effect of water content and temperature on seed longevity of seven Brassicaceae species after 5 years of storage.
2014
Maximising seed longevity is crucial for genetic resource preservation and longevity of orthodox seeds is determined by environmental conditions (water content and temperature). The effect of water content (down to 0.01 g·H₂O·g(-1) ) on seed viability was studied at different temperatures for a 5-year storage period in taxonomically related species. Seeds of seven Brassicaceae species (Brassica repanda, Eruca vesicaria, Malcolmia littorea, Moricandia arvensis, Rorippa nasturtium-aquaticum, Sinapis alba, Sisymbrium runcinatum) were stored at 48 environments comprising a combination of eight water contents, from 0.21 to 0.01 g·H₂O·g(-1) DW and six temperatures (45, 35, 20, 5, -25, -170 °C).
