Experiences, reputation, references and decision-making in an online hospitality network
2014
The aim of this thesis was to analyse behavioural patterns that occur after a negative experience during a hospitality exchange. The focus of this study is the largest online hospitality network to date, the CouchSurfing Project. CouchSurfing enables travellers to connect and to offer each other help in form of a free hospitality exchange. Furthermore, CouchSurfing presents a platform for cultural exchange and the possibility for members to connect in this online-offline community. As part of a qualitative study, a voluntary online questionnaire has been distributed and answered by 35 CouchSurfing members. The results give insight of how they deal with a negative experience after offline in…

Towards Successful Implementation of a Virtual Classroom for Vocational Higher Education in Indonesia
2019
The virtual classroom continues to grow, but it is becoming more and more the norm, and it is fundamentally different from the vocational students at the Indonesian university. With the promised benefits of the virtual classroom, many challenges and difficulties come in the implementation. Although there are already successful design principles for virtual classrooms that support organizations in overcoming the challenges, the approach to implementing the design principles of virtual classroom at the vocational higher education in Indonesia is still lacking. In this study, we aim to answer the research gap and used the design sciences research by interviewing the lecturers to design the sol…
HALE-IoT: HArdening LEgacy Internet-of-Things devices by retrofitting defensive firmware modifications and implants
2022
Internet-Of-Things (IoT) devices and their firmware are notorious for their lifelong vulnerabilities. As device infection increases, vendors also fail to release patches at a competitive pace. Despite security in IoT being an active area of research, prior work has mainly focused on vulnerability detection and exploitation, threat modelling, and protocol security. However, these methods are ineffective in preventing attacks against legacy and End-Of-Life devices that are already vulnerable. Current research mainly focuses on implementing and demonstrating the potential of malicious modifications. Hardening emerges as an effective solution to provide IoT devices with an additional layer of d…
P2PRealm - Peer-to-Peer Network Simulator
2006
Peer-to-peer realm (P2PRealm) is an efficient peer-to-peer network simulator for studying algorithms based on neural networks. In contrast to many simulators, which emphasize on detailed network simulation, the speed of simulation in P2PRealm is essential, because neural networks require a time consuming training phase. Efficiency has been obtained by optimizing training loops inside the simulator, using Java native interface (JNI) as well as distributing the simulator to hundreds of workstations using the P2PDisCo platform. In this paper we describe the architecture of P2PRealm and its input/output interfaces. Also, we present the mechanisms used for internally optimizing the implementatio…
JavaScript ja takaisinkutsut suomalaisilla verkkosivuilla : takaisinkutsumenetelmän yleisyys ja ongelmat
2016
JavaScript on hyvin paljon käytetty ohjelmointikieli ja verkkosivuilla vallitsevassa asemassa. JavaScript-kieliset ohjelmat sisältävät kuitenkin paljon virheitä. Verkkokeskusteluissa ”takaisinkutsuhelvetti”, eli tilanne jossa ohjelmakoodi on monien sisäkkäisten takaisinkutsullisten funktioiden vuoksi hyvin vaikesti ymmärrettävä ja hallittava, nostetaan yhdeksi kielen kipupisteistä. Tässä tutkimuksessa tutkittiin kirjallisuudesta JavaScriptin takaisinkutsumenetelmään liitettyjä ongelmia sekä sitä korvaavia asynkronisen toiminnan menetelmiä. Empiirisessä tutkimuksessa kartoitettiin suomalaisten verkkosivujen JavaScript-ohjelmakoodia. Ohjelmakoodin määriä, sijaintia ja ominaisuuksia mitattiin.…
Sharing media content in social media: The challenges and opportunities of user-distributed content (UDC)
2017
The article explores the distribution of mass media content by the online audience that connects by using the different social platforms, such as Facebook, Twitter and WhatsApp. The focus is on the new and developing concept of user-distributed content (UDC). From the viewpoint of media organisations, UDC is a process by which the mass media converge with online social networks through the intentional use of social media services and platforms in an effort to expand the distribution of media content. UDC does not have a long trajectory as a study object in media studies. The study suggests that practices related to UDC can be more strongly incorporated into management and journalism in main…
Avoimuudella on merkitystä! Kirjaston julkaisuyksikkö Jyväskylän yliopiston vaikuttavuuden edistäjänä
2012
Julkaisuyksikkö on toimintansa alusta alkaen tähdännyt Jyväskylän yliopiston näkyvyyden ja menestymisen sekä tieteen avoimuuden tukemiseen. Pekka Olsbo käy artikkelissaan läpi julkaisuyksikön toiminnan keskeisiä virstanpylväitä. Julkaisuyksikkö on vuosien saatossa vakiinnuttanut asemansa yliopiston keskeisenä palveluyksikkönä. Yliopistossa tuotettavien moninaisten digitaalisten aineistojen verkkojulkaisemisen myötä se myös jatkaa työtään kansallisen open access -työn eturintamassa. nonPeerReviewed
