FPGA-based Acceleration of Detecting Statistical Epistasis in GWAS

2014

Abstract Genotype-by-genotype interactions (epistasis) are believed to be a significant source of unexplained genetic variation causing complex chronic diseases but have been ignored in genome-wide association studies (GWAS) due to the computational burden of analysis. In this work we show how to benefit from FPGA technology for highly parallel creation of contingency tables in a systolic chain with a subsequent statistical test. We present the implementation for the FPGA-based hardware platform RIVYERA S6-LX150 containing 128 Xilinx Spartan6-LX150 FPGAs. For performance evaluation we compare against the method iLOCi[9]. iLOCi claims to outperform other available tools in terms of accuracy.…

Multimodal Communication and Peer Interaction during Equation-Solving Sessions with and without Tangible Technologies

2023

Despite the increasing use of technologies in the classroom, there are concerns that technology-enhanced learning environments may hinder students’ communication and interaction. In this study, we investigated how tangible technologies can enhance students’ multimodal communication and interaction during equation-solving pair work compared to working without such technologies. A tangible app for learning equation solving was developed and tested in fourth and fifth-grade classrooms with two class teachers and 24 students. Video data of the interventions were analysed using deductive and inductive content analysis. Coded data were also quantified for quantitative analysis. Additionally, teac…

Tablet-Supported Self-Assessment in a Class for Students with Intellectual Disability

2023

Self-assessment has been shown to have positive effects on students’ self-regulated learning strategies and academic achievement. However, self-assessment and self-assessment instruction are under-researched areas among students with intellectual disability. This data-driven qualitative study aimed at examining the self-assessment expressions students with intellectual disability documented in their learning diaries and how the teacher and teaching assistants used video recordings to facilitate students’ self-assessments in one Finnish special needs education class. The naturally occurring research data consisted of both students’ tablet-based learning diaries (N = 6) and video recordings o…

Item Response Trees: a recommended method for analyzing categorical data in behavioral studies

2015

Behavioral data are notable for presenting challenges to their statistical analysis, often due to the difficulties in measuring behavior on a quantitative scale. Instead, a range of qualitative alternative responses is recorded. These can often be understood as the outcome of a sequence of binary decisions. For example, faced by a predator, an individual may decide to flee or stay. If it stays, it may decide to freeze or display a threat and if it displays a threat, it may choose from several alternative forms of display. Here we argue that instead of being analyzed using traditional nonparametric statistics or a series of separate analyses split by response categories, this kind of data ca…

Puheviestintätaitojen arviointi : näkökulmia lukiolaisten esiintymis- ja ryhmätaitoihin

2003

Vuorovaikutustaidot ovat keskeinen osa yleissivistävän koulutuksen tuottamaa viestintäsivistystä. Lukiolaiset ovat myös voineet osallistua valtakunnalliseen puheviestinnän päättökokeeseen vuodesta 2000 lähtien. Yliassistentti Tarja Valkosen väitöstutkimus on ensimmäinen laaja-alainen selvitys siitä, miten lukiolaisten esiintymis- ja ryhmätaitoja ohjataan oppimaan ja arvioidaan. Se osoittaa, että päättökoe ja sen kehittelytyö ovat vaikuttaneet myönteisesti lukion puheviestinnän opetukseen. Lukiolaisten puheviestintätaitojen taso osoittautui tutkimuksessa keskimäärin hyväksi. Puhe-esitysten rakentamisen ja johdonmukaisen esittämisen taidot sekä esiintymisvarmuus kaipaavat kuitenkin kehittämis…

Towards Ethical Guidelines of Using Telepresence Robots in Residential Care

2021

AbstractRobotic telepresence is a potential technology to help alleviating the loneliness of elderly people. The impacts of long-term use of telepresence robots in residential care are not well known. We were interested in how using a telepresence robot influences the resident, family members and care workers at a facility, and what challenges and solutions there are for wider adoption of such robots in residential care. With a telepresence robot Double, we arranged a series of three trials in two separate residential care facilities: one 12-week trial in a private facility and two successive 6-week trials in a public facility. In each trial, we installed the telepresence robot in a room of…

Designing for Positive User Experience in Work Contexts: Experience Categories and their Applications

2018

Experience categories describe repeatedly occurring qualities of positive experiences that can be used for the analysis and generation of new/further/more positive experiences. This paper describes experience categories for the workplace. Based on 345 reports of positive user experiences in the workplace, we identified 17 experience categories through qualitative content analysis and describe their necessary and optional attributes. We believe that experience categories can support analysis and design activities for the work place in three ways: (a) using the questions derived from experience interviews to analyze existing positive experiences in work contexts, (b) explaining the potential …

Factory Workers' Ordinary User Experiences: An Overlooked Perspective

2018

Experiences with technology often are described as exciting and outstanding, for instance, in relation to novel technologies at home or at work. In this article, we aim to complement this perspective by emphasizing people’s mundane and ordinary experiences with technology, that is, unremarkable experiences happening in the background of people’s attention. Based on our investigations of user experience in a semiconductor factory, we show how such ordinary experiences are substantial in workers’ everyday interactions with technology, which are mainly shaped by repetitive activities and routines. However, current conceptions of user experience seem to overlook those mundane experiences and ho…
