Designing knowledge construction in pre-service teachers’ collaborative planning talk

2022

In this paper, we report on a qualitative study of student teachers’ collaboration in planning and implementing a course that integrated physics and the Finnish language. Audio-recorded planning sessions and interviews were examined using qualitative content analysis, first, to discover what kind of space for knowledge construction student teachers designed for learners and, second, to identify the characteristics of their collaboration in developing a new cross-disciplinary pedagogical practice. The analysis revealed challenges in integrating meaning-making resources for knowledge construction; especially the role of language remained mostly invisible. This indicates a need to develop teac…

A Novel Mathematical Model For TLCD: Theoretical And Experimental Investigations

2014

In this paper, a novel mathematical model for the Tuned Liquid Column Damper (TLCD) is presented. Taking advantages of fractional derivatives and related concepts, a new equation of motion of the liquid inside the TLCD is obtained. Experimental laboratory tests have been performed in order to validate the proposed linear fractional formulation. Comparison among experimental results, numerical obtained using the classical formulation and numerical with the new linear fractional formulation are reported. Results in frequency domain show how the new linear fractional formulation can predict the real behavior of such a passive vibration control system, more correctly than the classical mathemat…

Work stress and health problems of professional drivers: A hazardous formula for their safety outcomes

2018

BackgroundSeveral empirical studies have shown that professional drivers are a vulnerable occupational group, usually exposed to environmental stressors and adverse work conditions. Furthermore, recent studies have associated work-related stress with negative job performances and adverse health outcomes within this occupational group, including cardiovascular diseases and unsafe vehicle operation.ObjectiveThe aim of this study was to describe the working conditions and the health status of this occupational group, and to evaluate the association between the Demand–Control model of job stress and their self-reported health and safety outcomes.MethodsA pooled sample of 3,665 Colombian profess…

Impact of PNPLA3 and IFNL3 polymorphisms on hepatic steatosis in Asian patients with chronic hepatitis C.

2017

Background and aims A recent meta-analysis revealed that the genotype PNPLA3 rs738409 GG is associated with a higher risk of hepatic steatosis (HS) in Caucasian patients with chronic hepatitis C (CHC). However, controversial results were found regarding Asian populations. Furthermore, previous studies have shown a negative association between interferon lambda 3 (IFNL3) rs12979860 CC and HS in Caucasian CHC patients, but there have been no reports indicating any such association in Asian populations. In this study, then, we investigated the association of PNPLA3 and IFNL3 polymorphisms with HS in Asian CHC patients. Methods We enrolled consecutive CHC patients who underwent liver biopsy pri…

Nuclear Energy Density Optimization: UNEDF2

2014

The parameters of the UNEDF2 nuclear energy density functional (EDF) model were obtained in an optimization to experimental data consisting of nuclear binding energies, proton radii, odd-even mass staggering data, fission-isomer excitation energies, and single particle energies. In addition to parameter optimization, sensitivity analysis was done to obtain parameter uncertainties and correlations. The resulting UNEDF2 is an all-around EDF. However, the sensitivity analysis also demonstrated that the limits of current Skyrme-like EDFs have been reached and that novel approaches are called for.

Sosiaalinen media ja verkko-opiskelu

2010

 Koskelainen, Tiina Elina Tietojärjestelmätieteen kandidaatintutkielma / Tiina Koskelainen Jyväskylä: Jyväskylän yliopisto, 2009, 39 s. Kandidaatintutkielma Tässä tutkimuksessa kartoitetaan sosiaalisen median ominaispiirteitä sekä oppimisen ja verkko-opiskelun käsitteitä. Lisäksi tutkitaan millaisia vaikutuksia sosiaalisen median käytöllä on verkko-opiskeluun. Tutkimus on toteutettu kirjallisuuskatsauksena. Tieto- ja viestintäteknologian nopea kehitys, vuorovaikutukseen perustuvat kommunikointitavat sekä sosiaaliset sovellukset ovat lisänneet yhteisöllisyyttä ja mahdollistaneet sosiaalisen median kehittymisen. Käyttäjälähtöisyys, verkostoituminen ja uudet kommunikointitavat ovat muuttaneet …

T100: A modern classic ensemble to profile irony and stereotype spreaders

2022

In this work we propose a novel ensemble model based on deep learning and non-deep learning classifiers. The proposed model was developed by our team for participating at the Profiling Irony and Stereotype Spreaders (ISSs) task hosted at PAN@CLEF2022. Our ensemble (named T100), include a Logistic Regressor (LR) that classifies an author as ISS or not (nISS) considering the predictions provided by a first stage of classifiers. All these classifiers are able to reach state-of-the-art results on several text classification tasks. These classifiers (namely, the voters) are a Convolutional Neural Network (CNN), a Support Vector Machine (SVM), a Decision Tree (DT) and a Naive Bayes (NB) classifie…

Oral plus vaginal alpha-lipoic acid in women at risk for preterm delivery

2018

Objective: The etiology of preterm labor is multifactorial. An inflammatory response is always involved with the activation of NF-kB that determines synthesis and release of inflammatory molecules, implicated in fetal membrane activation, cervical modifications, abdominal pain and spontaneous uterine contractions. There is a close relationship between preterm birth and cervical shortening in the second quarter of pregnancy. We evaluated the benefits of alpha-lipoic acid administration on women considered at risk of preterm delivery due to the presence of symptoms (pelvic pain and uterine contractions) or reduced cervical length. Patients and Methods: This prospective observational study was…
