Numerical Simulations of the Flow Field of a Submerged Hydraulic Jump over Triangular Macroroughnesses

2021

The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity regi…

Personalisation in Journalism: Ethical insights and blindspots in Finnish legacy media

2022

The algorithmic personalisation and recommendation of media content has resulted in considerable discussion on related ethical, epistemic and societal concerns. While technologies of personalisation are widely employed by social media platforms, they are currently also being instituted in journalistic media. The objective of this study is to explore how concerns about algorithms are articulated and addressed when technologies of personalisation meet with long-standing journalistic values, norms and publicist missions. It first distinguishes five normative concerns related to personalisation: autonomy, opacity, privacy, selective exposure and discrimination. It then traces the ways that the…

The effects of two-way communication and chat service usage on consumer attitudes in the e-commerce retailing sector

2018

In e-commerce retailing (e-retailing), where competitors are only one click away and prices are easy to compare, providing superior customer service and reciprocal communication via a company’s website are important aspects of attracting and retaining customers. One increasingly popular solution to improve customer service is a “live chat” interface that allows consumers to have real-time conversations online with customer service agents. As the literature on the impacts of real-time communication via live chat is currently very limited, this study develops and tests a model that demonstrates the moderating effects of a chat service on the relationship between two-way communication (i.e., a…

When more is less: The other side of artificial intelligence recommendation

2022

Based on consumers' preferences, AI (artificial intelligence) recommendation automatically filters information, which provokes scholars' debate. Supporters believe that by analyzing the consumers' preferences, AI recommendation enables consumers to choose products more quickly and with lower cost. Critics deem that consumers are more easily trapped in information cocoons because of the use of AI recommendation. This reduces the possibility of consumers contacting with a variety of commodities, thus lowering the consumer decision quality. Based on experiments, this paper discusses the moderating role of AI recommendation on the relationship of consumers' preferences and information cocoons. …

Learning Slovak in new language learning environments

2017

The aim of this dissertation is to throw light on the development of teaching and learning Slovak in the new language learning environment. New developments in teaching led to the design of an experimental e-learning course in Slovak based on the philosophy of dynamic learning and using the metaphor of climbing a mountain for learning Slovak. The course was grounded in constructivist views of learning and teaching, which emphasize the importance of learning by doing and the process-like nature of learning. The teaching experiment included reflection-on-action research, with the goal of exploring learners' beliefs about themselves as e-learners before the course, and their perceptions and ex…

Using AI to personalise emotionally appealing advertisement

2019

Personal data and information collected online by companies can be used to design and personalise advisements. This chapter extends existing research into the online behavioural advertising by proposing a model that incorporates artificial intelligence and machine learning into developing emotionally appealing advertisements. It is proposed that big data and consumer analytics collected through AI from different sources will be aggregated to have a better understanding of consumers as individuals. Personalised emotionally appealing advertisements will be created with this information and shared digitally using pragmatic advertising strategies. Theoretically, this chapter contributes towards…

Transformative technologies, spatial changes : essays on mobile phones and the Internet

2009

Sakari Taipale tarkastelee väitöskirjassaan sitä, kuinka matkapuhelimen ja internetin käyttö vaikuttaa sosiaalisten tilojen muodostumiseen.Uudet informaatio- ja kommunikaatioteknologiat ovat monipuolistaneet sosiaalisen vuorovaikutuksen muotoja. Matkapuhelimen ja internetin avulla sosiaalisia tiloja, erilaisia toimijoiden yhteenliittymiä, voidaan luoda tietoverkoissa ilman toisten ihmisten fyysistä läsnäoloa. Tämän seurauksena sosiaalisen tilan kahden keskeisen osatekijän, rajojen ja tarkoituksen, välinen suhde on muuttunut. Rajat näyttävät menettäneen suhteellista merkitystään sosiaalisen tilan koossapysyvyyden kannalta, kun taas tilan tarkoituksen merkitys on vahvistunut.- Verkkoympäristö…

The Networked Utilisation of Satellite Images and Geospatial Technology in Journalism

2022

Satellite technology has become increasingly affordable and accessible in the past few decades. This has enabled many newsrooms to engage with genuinely remote journalism. This chapter explores the networked nature of satellite journalism and investigates its inclusion of experts and citizens outside newsrooms. Satellite journalism uses satellite-borne technology either as a (1) part of storytelling or (2) source of information. Academic research on the topic is scarce, so this chapter builds a base of knowledge on the contemporary practices, limitations and ethics—as well as directions of future development—of satellite journalism. By interviewing six journalists and one earth observation …

Liiketoimintaverkostoon vaikuttavat tekijät - teknologinen näkökulma

2013

Tutkielmassa tutkitaan liiketoimintaverkostoja ja siihen vaikuttavia tekijöitä, erityisesti teknologian näkökannalta. Liiketoimintaverkostolla tarkoitetaan verkostoa jossa toimii useampi yritys ja joita sitoo toisiinsa erilaiset suhteet. Teknologialla tarkoitetaan tutkielmassa kaikkea teknologiaa jota käytetään muun muassa informaation eri muotojen luomiseen, tallennukseen, kommunikointiin ja käyttöön. Tarkemmin on tarkasteltu internettiä ja sitä hyödyntäviä teknologioita kuten sähköpostia, videoneuvottelua ja erilaisia IOS-järjestelmiä sekä digitalisaatiota. Tutkielman tutkimuskysymyksiä tarkasteltiin liiketoimintaverkoston kolmen myytin ja kolmen paradoksin teorioiden kautta. Tutkimuksen …
