Ympäristövaikutusten arviointiin liittyvät selvitykset maatuulivoimahankkeissa
2016
Euroopan Unioni on asettanut Suomelle tavoitteeksi tuottaa 38 % energian loppukulutuksesta uusiutuvilla energiantuotantolähteillä vuonna 2020. Tuulivoima on Suomessa varsin uusi energiantuotantomuoto, minkä vuoksi tuulivoimahankkeiden YVA-menettelyjen (ympäristövaikutusten arviointimenettely) toteuttamistavat vaihtelevat paljon hankkeiden välillä. Tässä tutkimuksessa selvitettiin, miten maatuulivoimaloiden ympäristövaikutuksia on Suomessa arvioitu. Tarkastelu rajattiin tuulivoiman merkittävimpiin vaikutuksiin ja tutkimuksen laatijan omiin mielenkiinnon kohteisiin. Tutkimus on toteutettu dokumenttianalyysinä ennen vuoden 2014 syksyä valmistuneista YVA-selostuksista kaksivaiheisella koodausme…
An IPMSM torque/weight and torque/moment of inertia ratio optimization
2014
In this paper, a torque/weight and torque/moment of inertia ratio optimization procedure for interior permanent magnet syncronous motors (IPMSMs) is presented. More in detail, a performance comparison between several IPMSM rotor structures has been carried out in order to determine the optimum geometry that can maximize the torque/weight and torque/moment of inertia ratios. A commercial motor, with known electrical and mechanical characteristics, has been taken as reference. Its rotor structure has been modified several times, obtaining different rotor geometries and, therefore, many IPMSM models with different electrical and mechanical characteristics. The finite element method (FEM) analy…
Pienten lasten osallisuus vuorohoidon iltojen vuorovaikutustilanteissa
2021
Tutkimuksessa tarkastellaan, kuinka pienten lasten osallisuus toteutuu vuorohoidon iltojen vuorovaikutustilanteissa ja millaisia haasteita tähän liittyy. Aineisto kerättiin havainnoimalla 20–36 kk ikäisten lasten iltoja kahdessa erilaisessa vuoropäiväkodissa. Temaattisen analyysin perustana toimivat Lundyn (2007) kuvaamat, Yhdistyneiden Kansakuntien (YK) lapsen oikeuksien sopimuksen artiklaan 12 pohjautuvat lasten osallisuuden edellytykset. Huomion kohteena olivat erityisesti työntekijöiden toiminta ja sen lapsille luomat mahdollisuudet ilmaista mielipiteitään sekä tulla kuulluksi ja huomioiduksi. Muuttuva iltaryhmä sekä päiväkodin rutiinit ja säännöt rajoittivat toisinaan lasten osallisuud…
A Follow-Up On The Changes in the Changes in the Use Intention of Digital Wellness Technologies and Its Antecedents Over Time : The Use of Physical A…
2021
This study aims to further promote the understanding of the antecedents of the acceptance and use of digital wellness technologies among elderly people through a follow-up to our two prior studies, one which examines the potential longer-term temporal changes in the use intention of digital wellness technologies and its antecedents in the case of the young elderly segment and physical activity logger applications. We base this examination theoretically on UTAUT2 and empirically on survey data that is collected from 92 Finnish young elderly users of a physical activity logger application in three subsequent time points and analysed with partial least squares structural equation modelling (PL…
Forming Sustainable Physical Activity Programs Among Young Elderly : A Combined ELM & UTAUT Approach
2021
There is consensus in health studies that regular physical activities of sufficient intensity and duration contribute to better health both in the short and long term. In an ongoing research program, we focus on getting the young elderly, the 60-75 years age group, to adopt and include physical activities as part of their daily routines. One reason for addressing young elderly is large numbers – in Finland health care costs for the elderly was 3.7 B€ in 2019 and will increase dramatically if the young elderly group is in bad shape when they reach the 75+ age group. We are finding out that systematic physical activities can serve as preventive health care for the young elderly. We are also l…
Applying UTAUT2 to Explain the Use of Physical Activity Logger Applications Among Young Elderly
2020
Digital wellness technologies have been proposed as a promising way to promote the levels of physical activity and to solve the prevalent problem of physical inactivity among elderly people. In this study, we propose and test a research model for explaining the acceptance and use of these technologies in the case of the young elderly segment (people aged 60–75 years) and physical activity logger applications. The proposed model is theoretically founded on UTAUT2, and it is empirically tested by using the data collected from 115 Finnish young elderly users of a physical activity logger application and analysed with partial least squares based structural equation modelling (PLS-SEM). We find …
Narratives and Counter-Narratives about Radicalization: Experiences of Moderation of an Online Communication Campaign
2021
This paper presents the results of a cyber-ethnographic study. The research analyzes the dynamics that make, calm and increase the radicalization narratives. This study is part of the Oltre project (ISF - DG Migration and Home Affairs, EU) which directly involved 42 Italian and second generation youths in the dissemination and moderation of an online communication campaign in order to prevent radicalized behaviors. This paper illustrates how the young “moderators” interacted each other, highlighting how counter-narratives can represent useful tools for deconstructing "complex" issues such as radicalization. Furthermore, the paper shows (using social network analysis) how on the social media…
A valued partner or a mere support function : the role of marketing in Software-as-a-Service SMEs
2017
Ohjelmistoala on läpikäynyt valtavia muutoksia 2000-luvulla uusien teknologisten innovaatioiden syntyessä ja levitessä kiihtyvällä tahdilla. Pilvipalvelu on yksi tunnetuimmista innovaatioista ja kuvaa internetissä tapahtuvaa tietotekniikan käyttöä. Samaa nimitystä käytetään kaikista pilvessä tarjottavista palveluista, joista Software-as-a-Service (SaaS) on saanut laajimman suosion. Enemmistö uusista pilvipalveluorganisaatioista on pieniä tai keskisuuria yrityksiä, joilla on tutkimusten mukaan hyvin omalaatuinen tapa suunnitella ja toteuttaa markkinoinnin toimenpiteitä. Perinteiset suurille organisaatioille sopivat markkinoinnin teoriat ja mallit eivät istu nuorten ja ketterien ohjelmistoyri…
Towards a Contingency Framework for Engineering an Enterprise Architecture Planning Method
2007
Enterprise architecture (EA) has a key role in managing and relating business strategies and processes, information systems, and IC technologies. EA planning devises an EA plan with development steps to make necessary enhancements to the current state of the affairs in EA. Accomplishing EA planning in a systematic and efficient manner requires the availability of frameworks and methods suitable to the situation at hand. The selection and adaptation of these methodical artifacts for the use of EA planning is often quite challenging in practice. We argue that the contingency approach can help in these activities of method engineering (ME), and present a contingency framework (named here EACon…
