A tale of two frames : Exploring the role of framing in the use discontinuance of volitionally adopted technology
2022
https://doi.org/10.1111/isj.12355 The discontinuance of volitional IS (i.e., information systems adopted, used and discontinued at will) has recently attracted remarkable attention from academics and practitioners alike. However, most research to date has been ahistorical. Ignoring the temporal progression can be problematic when the phenomenon under investigation is dynamic and evolving. To balance this, we adopt a stage modelling approach to understand the process ending with the technology use being discontinued by users of a popular crowdsourcing platform. Two questions guided our investigation: (1) Why do users discontinue using an IS they have volitionally adopted and used? (2) How do…
Deliberate or Instinctive? : Proactive and Reactive Coping for Technostress
2019
Employees in organizations face technostress that is, stress from information technology (IT) use. Although technostress is a highly prevalent organizational phenomenon, there is a lack of theory-based understanding on how IT users can cope with it. We theorize and validate a model for deliberate proactive and instinctive reactive coping for technostress. Drawing from theories on coping, our model posits that the reactive coping behaviors of distress venting and distancing from IT can alleviate technostress by diminishing the negative effect of technostress creators on IT-enabled productivity. The proactive coping behaviors of positive reinterpretation and IT control can help IT users by in…
Multimodal accomplishment of alignment and affiliation in the local space of distant meetings
2017
Technology-mediated (i.e. distant) meetings are complex settings that involve distributed participation frameworks and the coordination of actions in multiple interactional spaces. This paper examines how problems with hearing, speaking, or understanding in the overall meeting space enable the negotiation of alignment and affiliation by co-present participants in the same local meeting space. Conversation analysis is used to investigate the local accomplishment of alignment and affiliation achieved through the sequential and temporal organization of verbal, embodied, and material resources of interaction in three types of situations: during technological trouble, silences, and disagreements…
Agency and Learning in the Work of Software Professionals
2017
This chapter addresses software professionals’ agency and learning in work characterized by a need for innovative learning and fluency in renewing work practices. The study presented was conducted with software professionals in a medium-sized Finnish company producing digital business applications. We applied a mixed-method approach to data collection and analysis. Regarding professional agency, we found a range of opportunities to influence work-related matters. The professionals were primarily able to influence their working hours and the order of their work tasks, but had fewer opportunities to influence customer projects, or their salary. To some extent they were able to develop themsel…
Integrating Docker to a Continuous Delivery pipeline : a pragmatic approach
2016
Docker on kevyt avoimen alustan sovellus, joka pystyy pakkaamaan sovelluksen kaikkien tarvittavien riippuvuuksien kanssa yhteen konttiin, ja tätä teknologiaa kutsutaan konttiteknologiaksi. Oikein käytettynä IT-ammattilaiset voivat saada konttiteknologiasta merkittäviä hyötyjä, sillä näitä paketteja voidaan helposti rakentaa, lähettää ja ajaa hajautetuissa järjestelmissä. Dockerin nousu on hämmästyttävää, sillä siitä on tullut konttiteknologian standardi vain kolmessa vuodessa ja se toimii jo nativisti Windowsilla sekä Linuxilla. Tämä teknologia tarjoaa suuria mahdollisuuksia tulevaisuuden ohjelmistokehitykselle sekä käyttöönotolle tarjoamalla uudenlaisia tapoja siirrettävyyden, skaalautuvuu…
Proximal and distal antecedents of problematic information technology use in organizations
2021
PurposeExcessive use of work-related information technology (IT) devices can lead to major performance and well-being concerns for organizations. Extant research has provided evidence of the incidence of such problematic IT use in organizations. We extend the understanding of problematic IT use by examining its individual (proximal) and organizational (distal) antecedents.Design/methodology/approachDrawing from the self-worth theory and the concept of fear of being left behind, we address proximal antecedents that lead to problematic IT use. Drawing from the concept of autonomy paradox, we address distal antecedents of problematic IT use through a positive association with the two proximal …

Automatic image-based identification and biomass estimation of invertebrates
2020
1. Understanding how biological communities respond to environmental changes is a key challenge in ecology and ecosystem management. The apparent decline of insect populations necessitates more biomonitoring but the time-consuming sorting and expert-based identification of taxa pose strong limitations on how many insect samples can be processed. In turn, this affects the scale of efforts to map and monitor invertebrate diversity altogether. Given recent advances in computer vision, we propose to enhance the standard human expert-based identification approach involving manual sorting and identification with an automatic image-based technology. 2. We describe a robot-enabled image-based ident…
Human experts vs. machines in taxa recognition
2020
The step of expert taxa recognition currently slows down the response time of many bioassessments. Shifting to quicker and cheaper state-of-the-art machine learning approaches is still met with expert scepticism towards the ability and logic of machines. In our study, we investigate both the differences in accuracy and in the identification logic of taxonomic experts and machines. We propose a systematic approach utilizing deep Convolutional Neural Nets with the transfer learning paradigm and extensively evaluate it over a multi-pose taxonomic dataset with hierarchical labels specifically created for this comparison. We also study the prediction accuracy on different ranks of taxonomic hier…
Innovation Initiatives in Large Software Companies : A Systematic Mapping Study
2018
Context: To keep the competitive advantage and adapt to changes in the market and technology, companies need to innovate in an organised, purposeful and systematic manner. However, due to their size and complexity, large companies tend to focus on the structure in maintaining their business, which can potentially lower their agility to innovate.Objective:The aims of this study are to provide an overview of the current research on innovation initiatives and to identify the challenges of implementing those initiatives in the context of large software companies.Method: The investigation was primarily performed using a systematic mapping approach of published literature on corporate innovation …
