Actual and Potential Pedagogical Use of Tablets in Schools

2013

This study reviews the potential of tablet technology for teaching and learning. In autumn 2012, we conducted a focused survey comprising quantitative and qualitative questions with Finnish teachers (N = 171, from 54 schools). We focused on perceived pedagogical opportunities and the actualized pedagogical potential of tablets at schools. The survey results indicate that the actual usefulness of tablets in schools was significantly less than what teachers perceived as the pedagogical potential. However, the results demonstrate the positive impact these devices are having on teaching and learning, as well as prompting changes in pedagogical perspectives. Teachers stated that tablets can dive…

Tietotekniikan valtakunnallisten oppisisältöjen toteutuminen Keski-Suomen peruskoulujen opetuskäytänteissä

2017

Tutkimus sai alkunsa kiinnostuksesta uusia Perusopetuksen opetussuunnitelman perusteita kohtaan. Vuonna 2014 hyväksytty POPS asettui erityisesti tieto- ja viestintätekniikan opetuksen osalta vastaamaan perusopetuksessa havaittuihin puutteisiin ja ongelmiin. Tutkimuksen tarkoituksena oli selvittää mitä uusia sisältöjä POPS14 tuo tietotekniikan opetukseen sekä kuinka noiden sisältöjen opetus toteutuu koulujen arjessa. Tutkimuksessa tunnistettiin tyypilliset ja yleisesti käytössä olevat TVT:n opetusmenetelmät ja niitä pyrittiin kuvailemaan laadullisen tutkimuksen keinoin. Tavoitteeseen päästiin lähinnä Opetushallituksen julkaisuihin kohdistuneen kirjallisuuskatsauksen, Keski-Suomen peruskouluj…

Moving from intention to behaviour: a randomised controlled trial protocol for an app-based physical activity intervention (i2be).

2022

IntroductionEfficacy tests of physical activity interventions indicate that many have limited or short-term efficacy, principally because they do not sufficiently build on theory-based processes that determine behaviour. The current study aims to address this limitation.Methods and analysisThe efficacy of the 8-week intervention will be tested using a three-condition randomised controlled trial delivered through an app, in women with a prior hypertensive pregnancy disorder. The intervention is based on the integrated behaviour change model, which outlines the motivational, volitional and automatic processes that lead to physical activity. The mechanisms by which the behaviour change techniq…

An Efficient Implementation of Parallel Parametric HRTF Models for Binaural Sound Synthesis in Mobile Multimedia

2020

The extended use of mobile multimedia devices in applications like gaming, 3D video and audio reproduction, immersive teleconferencing, or virtual and augmented reality, is demanding efficient algorithms and methodologies. All these applications require real-time spatial audio engines with the capability of dealing with intensive signal processing operations while facing a number of constraints related to computational cost, latency and energy consumption. Most mobile multimedia devices include a Graphics Processing Unit (GPU) that is primarily used to accelerate video processing tasks, providing high computational capabilities due to its inherent parallel architecture. This paper describes…

Towards a sociology of the mobile phone

2005

Use of the mobile phone is an immensely significant social and cultural phenomenon. However, market hype and utopian dreams greatly exaggerate its importance. The fundamental issue for sociology is the process of change. Bound up with contemporary issues of change, the mobile phone is a prime object for sociological attention both at the macro and micro levels of analysis. This article considers the strengths and weaknesses of four methods for studying the sociality of the mobile phone (social demography; political economy; conversation, discourse and text analysis; and ethnography), the different kinds of knowledge they produce, and the interests they represent. Recent ethnographic researc…

LoRa interference simulator

2018

This is a simulation tool for testing the performance of a LoRa link in case of collision between LoRa packets modulated with different spreading factors. You can use it for obtaining the results presented in Table 1 of our paper.

Monitoring Risk Factors and Improving Adherence to Therapy in Patients With Chronic Kidney Disease (Smit-CKD Project): Pilot Observational Study

2022

Background Chronic kidney disease is a major public health issue, with about 13% of the general adult population and 30% of the elderly affected. Patients in the last stage of this disease have an almost uniquely high risk of death and cardiovascular events, with reduced adherence to therapy representing an additional risk factor for cardiovascular morbidity and mortality. Considering the increased penetration of mobile phones, a mobile app could educate patients to autonomously monitor cardiorenal risk factors. Objective With this background in mind, we developed an integrated system of a server and app with the aim of improving self-monitoring of cardiovascular and renal risk factors and…

Consumer adoption of mobile technologies: a literature review

2015

Although the total number of mobile subscriptions reached 6.8 billion worldwide (ITU, 2013) confirming in the process that mobile technology is widespread, academic literature has so far focused only on explaining adoption of mobile technology and services. This literature review analyses 67 studies from the period 2005-2013 and finds the following: a) most studies are quantitative in nature and come from Asia; b) the Technology Acceptance Model is the most used theory; c) future research should also utilise qualitative methods and examine the behavioural outcomes of mobile adoption instead of simply adoption in consumer markets. peerReviewed

Who are the Showroomers? Socio-Demographic Factors Behind the Showrooming Behavior on Mobile Devices

2022

This quantitative study focuses on socio-demographic variables and their associations with different forms of showrooming behavior. The purpose of this study is to find which consumer groups based on age, gender, and income level are demographically the most probable showroomers, and how much each of these variables explain showrooming. The data used is a structured online survey from 1,028 Finnish omnichannel consumers aged between 18 and 75 years. We compare the means of demographic groups’ shares on different aspects of showrooming, and then use partial least squares structural equation modeling with confirmatory factor analysis to see how much each of the variables explain showrooming. …
