A Framework for a Smart City Design : Digital Transformation in the Helsinki Smart City
2019
Recently, there has been substantial interest in the concept of a smart city, as it has been a viable solution to the dilemmas created by the urbanization of cities. Digital technologies—such as Internet-of-Things, artificial intelligence, big data, and geospatial technologies—are closely associated with the concept of a smart city. By means of modern digital technologies, cities aim to optimize their performance and services. Further, cities actively endorse modern digital technologies to foster digitalization and the emergence of data-based innovations and a knowledge economy. In this paper, a framework for a smart city design is presented. The framework considers a smart city from the pe…
Towards a Trustful Digital World : Exploring Self-Sovereign Identity Ecosystems
2021
In the current global situation-burdened by, among others, a vast number of people without formal identification, digital leap, the need for health passports and contact tracking applications-providing private and secure digital identity for individuals, organizations and other entities is crucial. The emerging self-sovereign identity (SSI) solutions rely on distributed ledger technologies and verifiable credentials and have the potential to enable trustful digital interactions. In this human-centric paradigm, trust among actors can be established in a decentralized manner while the identity holders are able to own and control their confidential data. In this paper, we build on observations…
Navigating in the Digital Jungle : Articulating Combinatory Affordances of Digital Infrastructures for Collaboration
2019
During digital transformation, companies integrate digital technologies creating large and complex digital infrastructures. These digital infrastructures hold combinatory affordances enabling companies to achieve outcomes that are more than the sum of their parts (i.e., the individual digital technologies). Owing to the complexity of digital infrastructures, these combinatory affordances are ever-present but hidden in the thicket of the infrastructure making their effective use a challenge. We report on an ethnographic study of a large German car manufacturer (Car Inc.) that increasingly integrated digital technologies into its infrastructure as part of its digital transformation strategy. …
Adoption of a COVID-19 Contact Tracing App Among Older Internet Users in Finland
2022
The outbreak of the COVID-19 pandemic created an unequal need for limiting physical contacts and tracing possible exposures to a novel coronavirus. Smartphone-based contact tracing applications (CTAs) were presented as a vehicle for stopping virus transmission chains and supporting the work of contact tracing teams. In this study, older adults’ adoption of a CTA was studied using socioeconomic background factors, satisfaction with health, and the measure of digital activity as predictors. The data were drawn from a larger questionnaire survey targeted at older internet users. A subsample of older Finnish internet users (N = 723) was analyzed using a logistic regression model. Results showed…
Digitaalisen kommunikaatiosovelluksen kehittäminen kodin ja koulun vuorovaikutuksen edistämiseksi
2006
Juha-Matti Latvala tutki väitöstyössään mahdollisuuksia parantaa kodin ja koulun välistä viestintää nykyaikaista tekniikkaa hyväksi käyttäen. Jyväskylän yliopiston MUKAVA-hankkeessa kehitettiin vuosina 2003–2005 Kivahkoksi nimetty sovellus. Latvala tarkastelee sovelluksen käyttäjälähtöistä kehitysprosessia sekä sovelluksen merkitystä kokeiluun osallistuneiden luokkien oppilaiden vanhemmille ja opettajille.Latvalan kuvaaman tutkimus- ja kehitysprosessin tulos, Kivahko-viestintäsovellus, on teknisen ja sosiaalisen innovaation yhdistelmä. Se yhdistää olemassa olevia tekniikoita uuteen käyttötarkoitukseen ja parantaa käytänteitä kodin ja koulun yhteistyössä. Viestintäsovellus on tarkoitettu kod…
More years, more technologies : aging in the digital era
2018
This special issue presents research on the role of digital health and communication technologies in later life. Drawing from the observation that people’s longer lives are affected by digital technologies to varying extents and recognizing the vast supply of traditional and digital technologies targeted at older users, we maintain that the principle of aged heterogeneity also manifests itself with respect to the adoption and use of digital technologies. Basing on the findings presented in the articles of the issue, we conclude n this introduction to the issue that the concept of aged heterogeneity and the particularities of old age as a stage of life are still insufficiently incorporated i…
Sosiaali-, terveys- ja kuntoutusalan opettajien digitaalinen osaaminen
2020
Tiivistelmä Tutkimuksen tarkoituksena oli kuvata sosiaali-, terveys- ja kuntoutusalan (soteku) opettajien (n=388) digitaalista osaamista osana TerOpe-hanketta. Aineisto kerättiin DigCompEdu CheckIn Self-reflection Tool -itsearviointityökaluun perustuvalla mittarilla, joka sisälsi 21 (strukturoitua) väittämää ja yhden avoimen kysymyksen. DigCompEdu-viitekehyksen kuutta osa-aluetta (ammatillinen sitoutuminen, digitaaliset resurssit, opettaminen ja oppiminen, arviointi, oppijoiden voimaannuttaminen ja oppijoiden digitaalisen osaamisen tukeminen) käytettiin sekä määrällisen aineiston keskiarvomuuttujien muodostamisessa että laadullisen aineiston deduktiivis-induktiivisen analyysin runkona. Opet…
Instrumentation for time-of-flight elastic recoil detection analysis
2016
Time-of-flight elastic recoil detection is an ion beam based method to analyze the elemental composition of thin film samples at different depths. In order to improve the mass resolution and to enable kinematic correction a position sensitive gas ionization chamber energy detector was constructed. This detector along with pre-existing timing detectors were connected to a modern fully digitizing data acquisition setup. This thesis describes the design of these instruments, including all aspects from the mechanical design of the gas ionization detector to the algorithm and software development of the digitizing acquisition setup. The performance of the system has been studied with measurements …
Improving Smart City Design : A Conceptual Model for Governing Complex Smart City Ecosystems
2018
Smart city concept is a viable nominee to solve the dilemmas urbanization creates globally. By means of digital technologies like Internet-of-Things, artificial intelligence and data analytics cities aim to optimize city performances like mobility, environment, security, health care and social services. Furthermore, cities actively endorse usage of digital technologies to foster digitalization and new business innovation to nurture local economy and social well-being. Smart city market is growing, but simultaneously fragmented smart city markets and initiatives face challenges with governance, ecosystem orchestration and continuity. Transformation to smart city is a complex long-term proces…
