Interventiovastemallien tarjoamat mahdollisuudet kolmiportaisen tuen mallin kehittämiseen : esimerkkinä matematiikan oppimisen tuki

2015

Tässä katsausartikkelissa esitellään Yhdysvalloissa monin paikoin käytössä olevaa interventiovastemallia (Response to Intervention, RTI), joka sisältää tutkimusperustaisen näkökulman koulussa annettavaan oppimisen tukeen. Ennen kaikkea pohditaan interventiovastemallille ominaisen tuen tiheyden, keston ja arvioinnin merkitystä ja hyödynnettävyyttä suomalaisessa kolmiportaisen tuen mallissa. Lopuksi esitetään jatkokeskustelua ja -tutkimusta varten matematiikan oppimisen tuen kolmivaihemalli, johon on yhdistelty RTI-lähestymistapaa matematiikan oppimisvaikeuksiin annettavan tuen osalta ja joka kuitenkin on suomalaisen lainsäädännön mukainen. Kolmivaihemalli pohjaa yksityiskohdiltaan yhdysvalta…

Stability, electronic structure, and optical properties of protected gold-doped silver Ag29−xAux (x = 0–5) nanoclusters

2017

In this work, we used density functional theory (DFT) and linear response time-dependent DFT (LR-TDDFT) to investigate the stability, electronic structure, and optical properties of Au-doped [Ag29-xAux(BDT)12(TPP)4]3- nanoclusters (BDT: 1,3-benzenedithiol; TPP triphenylphosphine) with x = 0-5. The aim of this work is to shed light on the most favorable doped structures by comparing our results with previously published experimental data. The calculated relative energies, ranging between 0.8 and 10 meV per atom, indicate that several doped Ag29-xAux nanoclusters are likely to co-exist at room temperature. However, only the Au-doped [Ag29-xAux(BDT)12(TPP)4]3- nanoclusters that have direct bon…

Sex steroid hormone receptors, their ligands, and nuclear and non-nuclear pathways

2015

The ability of a cell to respond to a particular hormone depends on the presence of specific receptors for those hormones. Once the hormone has bound to its receptor, and following structural and biochemical modifications to the receptor, it separates from cytoplasmic chaperone proteins, thereby exposing the nuclear localization sequences that result in the activation of the receptor and initiation of the biological actions of the hormone on the target cell. In addition, recent work has demonstrated new pathways of steroid signaling through orphan and cell surface receptors that contribute to more rapid, “non-nuclear” or non-transcriptional effects of steroid hormones, often involving G-pro…

Heart Rate Variability Monitoring During Strength and High-Intensity Interval Training Overload Microcycles

2019

Objective: In two independent study arms, we determine the effects of strength training (ST) and high-intensity interval training (HIIT) overload on cardiac autonomic modulation by measuring heart rate (HR) and vagal heart rate variability (HRV). Methods: In the study, 37 well-trained athletes (ST: 7 female, 12 male; HIIT: 9 female, 9 male) were subjected to orthostatic tests (HR and HRV recordings) each day during a 4-day baseline period, a 6-day overload microcycle, and a 4-day recovery period. Discipline-specific performance was assessed before and 1 and 4 days after training. Results: Following ST overload, supine HR, and vagal HRV (Ln RMSSD) were clearly increased and decreased (small …

Oxygen uptake, acid-base balance and hormonal responses in maximal 300 - 400 m running in child, adolescent and adult athletes

2013

Vilmi, Nikke (2013). Oxygen uptake, acid-base balance and hormonal responses in maximal 300 - 400 m running in child, adolescent and adult athletes. Department of Biology of Physical Activity, University of Jyväskylä, Master's thesis, Science of Sport Coaching and Fitness Testing, 55 pp. The 400 m sprint demands both aerobic and anaerobic energy systems. During the race the acid-base balance of the body is disturbed and that has effects on the oxygen uptake. The purpose of this study was to investigate the oxygen uptake and acid-base balance during and after the maximal anaerobic running test in child (300 m), adolescent (350 m) and adult (400 m) athletes. Furthermore, the aim was also to d…

Oxymetazoline modulates proinflammatory cytokines and the T‐cell stimulatory capacity of dendritic cells

2007

The nasal decongestant oxymetazoline (OMZ) is frequently used in the topical treatment of rhinitis/sinusitis. As proinflammatory cytokines play a critical role in the development and maintenance of local inflammation, the aim of this study was to investigate the influence of OMZ on immune cells in order to diminish the mucosal infiltration of the nose. Peripheral blood mononuclear cells (PBMC) from buffy coats of healthy volunteers were isolated and stimulated in the presence or absence of OMZ. In addition, monocyte-derived dendritic cells (DC) were generated and different concentrations of OMZ were added. DC phenotype and their T-cell stimulatory properties were analysed. The vasoactive su…

To feed back or to feed forward? : Students' experiences of and responses to feedback in a Finnish EFL classroom

2017

Good feedback is a powerful element in learning. Ultimately, however, the impact feedback has on learning depends on how the learner responds to that feedback. So far, foreign or second language studies on feedback have mainly concentrated on different methods of error correction, not on students’ responses to feedback in general. This study aims to find out what students thought of the feedback they had received in their EFL studies. Furthermore, the study seeks to discover students’ different responses to that feedback. The data was gathered using a web-based questionnaire filled out by 140 students. The students, aged 17–19, were all from a single Finnish upper secondary school. The data…

Hormesis: Decoding Two Sides of the Same Coin

2015

In the paradigm of drug administration, determining the correct dosage of a therapeutic is often a challenge. Several drugs have been noted to demonstrate contradictory effects per se at high and low doses. This duality in function of a drug at different concentrations is known as hormesis. Therefore, it becomes necessary to study these biphasic functions in order to understand the mechanistic basis of their effects. In this article, we focus on different molecules and pathways associated with diseases that possess a duality in their function and thus prove to be the seat of hormesis. In particular, we have highlighted the pathways and factors involved in the progression of cancer and how t…
