Minimum Description Length Based Hidden Markov Model Clustering for Life Sequence Analysis

2010

In this article, a model-based method for clustering life sequences is suggested. In the social sciences, model-free clustering methods are often used in order to find typical life sequences. The suggested method, which is based on hidden Markov models, provides principled probabilistic ranking of candidate clusterings for choosing the best solution. After presenting the principle of the method and algorithm, the method is tested with real life data, where it finds eight descriptive clusters with clear probabilistic structures. nonPeerReviewed

Ammattikorkeakouluopiskelijoiden uupumus, imu ja kuormituksesta palautuminen

2010

Tässä pro gradu -tutkielmassa selvitettiin ammattikorkeakouluopiskelijoiden opiskelu-uupumusta, opiskeluintoa ja kuormituksesta palautumista. Tutkimuksen tavoitteena oli lisätä ymmärrystä ammattikorkeakouluopiskelijoiden hyvinvoinnista ja paneutua tuoreeseen tutkimusaiheeseen, josta toistaiseksi on olemassa vain vähän aiempaa tutkimustietoa. Tutkimus toteutettiin internet-kyselynä, johon vastasi 582 ensimmäisen ja kolmannen vuoden ammattikorkeakouluopiskelijaa. Tutkimuksen tulokset osoittivat, että opiskelu-uupumuksen ja -innon kokeminen oli varsin yleistä ammattikorkeakouluopiskelijoiden keskuudessa. Erityisesti naiset, opiskelun loppuvaihe sekä kokemus opintojen odotettua huonommasta eten…

Predicting delayed letter name knowledge and its relation to grade 1 reading achievement in children with and without familial risk for dyslexia

2006

The authors examined the developmental trajectories of children's early letter knowledge in relation to measures spanning and encompassing their prior language-related and cognitive measures and environmental factors and their subsequent Grade 1 reading achievement. Letter knowledge was assessed longitudinally at ages 4.5, 5.0, 5.5, and 6.5 years; earlier language skills and environmental factors were assessed at ages 3.5 and 4.5 years; and reading achievement was assessed at the beginning and end of Grade 1. The analyses were conducted on a longitudinal data set involving children with and without familial risk for dyslexia. Emerging from the trajectory analysis of letter knowledge were 3 …
