Vertaisarvioinnin harjoitusohjelma ja vertaisarviointien toteutus Ketosen väitöskirjassa
2021
Tämä materiaali on suomenkielinen kuvaus vertaisarviointi-intervention toteutuksesta Ketosen (2021) väitöskirjassa. Toteutus sisältää vertaisarvioinnin harjoituksia ja varsinaisia vertaisarviointeja. Interventio kesti 1,5 vuotta ja se toteutettiin fysiikan ja kemian oppiaineissa luokka-asteilla 7-8 vuosien 2018-2019 aikana. Harjoitukset ja vertaisarvioinnit on materiaalissa kuvattu siinä järjestyksessä, jossa ne tutkimuksessa toteutettiin. Interventio suunniteltiin vertaisarvioinnin aiempaa tutkimustietoa peruskoulun kontekstiin soveltaen. Materiaali toimii esimerkkinä siitä, miten vertaisarviointia voi harjoitella ja toteuttaa peruskoulussa osana oppiaineen opiskelua. This material is a de…
Kyselytutkimus fysio- ja toimintaterapeuteille GAS-menetelmän käyttökokemuksista
2014
TIIVISTELMÄ Jenni Tuomi 2014 Kyselytutkimus fysio- ja toimintaterapeuteille GAS-menetelmän käyttökokemuksista Liikuntatieteellinen tiedekunta Terveystieteiden laitos Jyväskylän yliopisto 53 sivua, 4 liitettä Goal attainment scaling (GAS-menetelmä) on 1960-luvulla kehitetty menetelmä kuntoutuksen tavoitteiden asettamiseen ja arviointiin. Tutkimuksen tarkoituksena oli saada tietoa fysio- ja toimintaterapeuttien käyttökokemuksista GAS-menetelmästä. Tarkoituksena oli lisäksi selvit-tää, mitä hyötyjä ja haasteita GASin käyttöön liittyy. Aineisto (n=29) kerättiin kyselytutkimuksena syksyn 2013 ja kevään 2014 aikana. Taustatie-toina selvitettiin sukupuoli, ikä, ammatti, työskentelykaupunki, työkok…
Go-tekoälyjen toteutusratkaisuja
2009
Go tarjoaa tekoälytutkijoille jatkuvasti uusia haasteita ja tapoja testata ideoitaan. Toistaiseksi ei ole vielä onnistuttu kehittämään tekoälyä, jota ihminen ei voisi voittaa, mutta yrityksiä on monenlaisia. Yksinkertaisista säännöistä huolimatta go on hyvin strateginen ja taktinen peli ja gon ratkaisemista pidetään yleisenä tavoitteena tekoälytutkimuksessa.
Assessing the Performance of Interactive Multiobjective Optimization Methods
2021
Interactive methods are useful decision-making tools for multiobjective optimization problems, because they allow a decision-maker to provide her/his preference information iteratively in a comfortable way at the same time as (s)he learns about all different aspects of the problem. A wide variety of interactive methods is nowadays available, and they differ from each other in both technical aspects and type of preference information employed. Therefore, assessing the performance of interactive methods can help users to choose the most appropriate one for a given problem. This is a challenging task, which has been tackled from different perspectives in the published literature. We present a …
GDL90fuzz: Fuzzing - GDL-90 Data Interface Specification Within Aviation Software and Avionics Devices–A Cybersecurity Pentesting Perspective
2022
As the core part of next-generation air transportation systems, the Automatic Dependent Surveillance-Broadcast (ADS-B) is becoming very popular. However, many (if not most) ADS-B devices and implementations support and rely on Garmin’s GDL-90 protocol for data exchange and encapsulation. In this paper, we research GDL-90 protocol fuzzing options and demonstrate practical Denial-of-Service (DoS) attacks on popular Electronic Flight Bag (EFB) software operating on mobile devices. For this purpose, we specifically configured our own avionics pentesting platform. and targeted the popular Garmin’s GDL-90 protocol as the industry-leading devices operate on it. We captured legitimate traffic from …
Interactivized : Visual Interaction for Better Decisions with Interactive Multiobjective Optimization
2022
In today’s data-driven world, decision makers are facing many conflicting objectives. Since there is usually no solution that optimizes all objectives simultaneously, the aim is to identify a solution with acceptable trade-offs. Interactive multiobjective optimization methods are iterative processes in which a human decision maker repeatedly provides one’s preferences to request computing new solutions and compares them. With these methods, the decision maker can learn about the problem and its limitations. However, advanced optimization software usually offer simple visualization tools that can be significantly improved. On the other hand, current approaches for multiobjective optimization…
Life-space mobility assessment in older people in Finland; measurement properties in winter and spring.
2014
Background: Life-space mobility refers to the spatial area an individual moves through, the frequency and need for assistance. Based on the assumption that measurement scale properties are context-specific, we tested the scale distribution, responsiveness, and reproducibility of the 15-item University of Alabama at Birmingham Study of Aging Life-Space Assessment in older people in Finland, specifically accounting for season. Methods: Community-dwelling older men and women in cent ral Finland aged 75-90 y ears were interviewed to determine life-space mobility (score range 0-120). Baseline (January-June 2012) and one-year follow-up data (January-June 2013; n = 806) from the cohort study “ Lif…
Investigation of antihypertensive class, dementia, and cognitive decline: a meta-analysis
2020
ObjectiveHigh blood pressure is one of the main modifiable risk factors for dementia. However, there is conflicting evidence regarding the best antihypertensive class for optimizing cognition. Our objective was to determine whether any particular antihypertensive class was associated with a reduced risk of cognitive decline or dementia using comprehensive meta-analysis including reanalysis of original participant data.MethodsTo identify suitable studies, MEDLINE, Embase, and PsycINFO and preexisting study consortia were searched from inception to December 2017. Authors of prospective longitudinal human studies or trials of antihypertensives were contacted for data sharing and collaboration.…
Demographic Differences in the Effectiveness of a Physical Activity Application to Promote Physical Activity: Study Among Aged People
2021
The global population is ageing and simultaneously the life expectancy at older ages is improving. To support healthy and active aging, it is imperative to find solutions to support physical activity (PA) in older age. Digital wellness technologies are a potential solution, but in order for such technologies to be successful, research is needed to gain a better understanding on their use and effectiveness among aged people. To address this need, this study investigated the effectiveness of a physical activity application to promote PA behavior among aged people of different demographics (gender, age, education, marital status). PA levels were measured before taking the application into use …
Monitoring peatland water table depth with optical and radar satellite imagery
2022
Peatland water table depth (WTD) and wetness have widely been monitored with optical and synthetic aperture radar (SAR) remote sensing but there is a lack of studies that have used multi-sensor data, i.e., combination of optical and SAR data. We assessed how well WTD can be monitored with remote sensing data, whether multi-sensor approach boosts explanatory capacity and whether there are differences in regression performance between data and peatland types. Our data consisted of continuous multiannual WTD data from altogether 50 restored and undrained Finnish peatlands, and optical (Landsat 5–8, Sentinel-2) and Sentinel-1 C-band SAR data processed in Google Earth Engine. We calculated rando…
