Is 're-calibration' of standard cardiovascular disease (CVD) risk algorithms the panacea to improved CVD risk prediction and prevention?

Musical Feature and Novelty Curve Characterizations as Predictors of Segmentation Accuracy

2017

Novelty detection is a well-established method for analyzing the structure of music based on acoustic descriptors. Work on novelty-based segmentation prediction has mainly concentrated on enhancement of features and similarity matrices, novelty kernel computation and peak detection. Less attention, however, has been paid to characteristics of musical features and novelty curves, and their contribution to segmentation accuracy. This is particularly important as it can help unearth acoustic cues prompting perceptual segmentation and find new determinants of segmentation model performance. This study focused on spectral, rhythmic and harmonic prediction of perceptual segmentation density, whic…

Alcohol drinking behavior and its developmental antecedents

2006

Juomiskäyttäytymisen pitkän aikavälin muotoutumisesta tiedetään varsin vähän, sillä tutkimuksia samojen ihmisten käyttäytymisestä lapsuudesta aikuisuuteen on maailmassa vain muutama. Pitkänen osoitti tutkimuksessaan, että varhainen päihteiden käyttö, heikko itsehallinta ja kouluiän ongelmat ennakoivat alkoholin ongelmakäyttöä.Perhetaustaan liittyvät ongelmat, erityisesti vaikeudet vanhemmuudessa sekä vanhempien alkoholinkäyttö ja äidin tupakoiminen lisäsivät riskiä sekä varhaiseen alkoholinkäytön aloittamiseen että aikuisiän ongelmajuomiseen. Heikko itsehallinta ja koulusopeutumattomuus 14-vuotiaana sekä pojilla heikko itsehallinta jo lapsuudessa olivat myös keskeisiä aikuisiän alkoholin on…

The Predictors of Literacy Skills among Monolingual and Bilingual Finnish–Swedish Children During First Grade

2021

The aim of the study was to examine which predictor variables are related to literacy skills among monolingual Swedish (n = 269) and bilingual Finnish–Swedish (n = 229) children at the first grade in the Swedish-speaking schools in Finland. The participants were assessed in phonological awareness, letter knowledge, rapid automatized naming (RAN), word recognition, reading fluency, and spelling. The results showed that RAN was the most significant predictor of reading and spelling skills in both language groups, and monolingual children performed significantly better in RAN. Moreover, letter knowledge predicted reading and spelling skills in both groups. However, no significant differences b…
