Information and communication technology in retailing: A cross-industry comparison
2009
Abstract Information technology (IT) may represent a source of competitive advantage for businesses in general and for retailers in particular. However, there is debate in the literature over the usefulness of investing in technology. This paper aims at analyzing the relationship between consumers’ perception on the use of information and communication technology by the retailer and consumer satisfaction with retailer technologies. Results support the need to restrict the investment in IT to what is strictly necessary, although there are significant differences according to retailer activity.
Developing Solutions For Healthcare : Deploying Artificial Intelligence to an Evolving Target
2017
—The pace of deploying artificial intelligence (AI) techniques to healthcare has been speeding up. Many of the initiatives have been technology driven aiming at finding problems matching the new technology while systematic, demand driven search for solutions has been limited. Here we describe the process of identifying opportunities for deploying artificial intelligence to healthcare and social services on regional and national levels in Finland. The process includes idea generation and elaboration using a design thinking method complemented with architectural design for identifying required AI capabilities for the 34 best use cases. In this paper, we focus on the development of use case “M…
Dielectric spectroscopy as a potential technique for prediction of kiwifruit quality indices during storage
2019
Dielectric spectroscopy has been employed as a simple, low cost and a non-destructive way for prediction of some physicochemical indices of kiwifruit during storage. A parallel-plate capacitor was developed and supplied with sinusoidal voltage waves within a frequency range of 40 kHz – 20 MHz. Dielectric properties of samples were measured by the dielectric sensor. Additionally, changes associated with fruit ripening properties, including firmness, total soluble solid (TSS) and pH were determined as a function of time at 2 °C. The results showed that storage time significantly affected the quality characteristics of kiwifruit. Artificial neural networks (ANNs) were employed to develop model…
Antiferromagnetism and p‐type conductivity of nonstoichiometric nickel oxide thin films
2020
Plasma‐enhanced atomic layer deposition was used to grow non‐stoichiometric nickel oxide thin films with low impurity content, high crystalline quality, and p‐type conductivity. Despite the non‐stoichiometry, the films retained the antiferromagnetic property of NiO.
On attracting sets in artificial networks: cross activation
2018
Mathematical models of artificial networks can be formulated in terms of dynamical systems describing the behaviour of a network over time. The interrelation between nodes (elements) of a network is encoded in the regulatory matrix. We consider a system of ordinary differential equations that describes in particular also genomic regulatory networks (GRN) and contains a sigmoidal function. The results are presented on attractors of such systems for a particular case of cross activation. The regulatory matrix is then of particular form consisting of unit entries everywhere except the main diagonal. We show that such a system can have not more than three critical points. At least n–1 eigenvalu…
Medical Student Motivation to Work in E-learning
2015
Nowadays information technology is widley used in studying process thus enabling students to acquire knowledge in a convenient place and time. It is a novel approach and a challenge for both – the students and the faculty of Latvian University Riga Medical College (LU RMK). In order to provide and develope e-learning environment LU RMK has launched a Project whose main objective is „to develop guidelines and video training materials in the e-environment for students and faculty staff in order to provide a more efficient studying process”. Implementation of the project has been started with a pilot study „Medical students’ motivation to work in e-environment”, designed to explore students’ m…

La utilització de WebQuest i de Sistemes de Resposta Interactiva en l'assignatura Investigació de Mercats
2010
Aquest treball té com objectiu estudiar la importància d'implantar metodologies docents centrades en les noves tecnologies de la informació i comunicació (TIC), amb la finalitat de potenciar la participació de l'estudiant i de millorar els seus resultats d'aprenentatge. Concretament,aprofundirem en el disseny d'una WebQuest i en l'ús de Sistemes de Resposta Interactiva en l'assignatura Investigació de Mercats. Els resultats obtinguts serviran de base per a dissenyar les guies i metodologies docents de les assignatures de l'àrea de Comercialització i Investigació de Mercats en els nous estudis de grau.
The effect of time and place dependence when utilizing video lectures
2009
In many learning institutes, diversification of teaching with the help of various technologies has become an essential part of educational arrangements. With the increase in the use of networks for teaching purposes, the use of streaming videos is now one of the possibilities to be reckoned with in trying to increase flexibility in studies. Specially recorded on-demand videos provide the students with better chances to decide when, where and how to study. Information on how students use on-demand videos can be obtained, apart from student questionnaires, from the log files of a media server. These files offer an information source that, on the one hand, is diverse but, on the other, cumbers…
Diversification of adult education with the help of video lectures
2010
For some years now, adult education and working while studying have had an important role in the modern society. Mature-age study brings with it some special features, such as time use limitations, which must be taken into account when creating educational programmes for the students concerned. Above all, flexibility must become a major feature of participation in education. In relation to the Master Studies in Mathematical Information Technology at Kokkola University Consortium, the aim for some years now has been to increase that flexibility by diversifying traditional lecture teaching with the help of real-time and on-demand video lectures. With the help of the results presented in this …
