Towards an integrated approach to emergency management: interdisciplinary challenges for research and practice
2015
This article presents an interdisciplinary vision for large-scale integrated emergency management that has been inspired by the transition from platform centric to integrated operations in the oil and gas fields, which uses remote emergency control centres collaborating virtually with local responders. The article discusses some of the most salient research challenges for integrated emergency management, including the role of mobile technology, human-centred sensing, citizen participation and social media, and the socio-cultural determinants of disaster management. The purpose of this article is to frame an integrated emergency management approach that adopts a multi-disciplinary approach, …

Folk theories of algorithmic operations during Internet use: A mixed methods study
2021
We used the folk theory perspective to investigate Internet users’ understanding of algorithms during their Internet use. Empirically, we conducted a mixed-method study. First, we carried out semi-...
Social media as a place to see and be seen : Exploring factors affecting job attainment via social media
2023
Job seekers can utilize social media platforms to actively search for job opportunities and also receive unsolicited job offers from recruiters and employers. Using data from a representative sample of Finnish social media users, this article studies both aspects of social media job attainment by analyzing how much individuals successfully apply for jobs and get recruited to positions through social media. Results show that the prevalence of successfully applying to jobs through social media does not differ statistically between socio-economic groups, but the prevalence of getting recruited to jobs through social media is greater within higher socio-economic groups. LinkedIn users are more …
Designing Deliberation Systems
2010
In a liberal democracy, the evolution of political agendas and formation of policy involves deliberation: serious consideration of political issues. Modern day political participation is dependent on widespread deliberation supported by information and communication technologies, which also offer the potential to revitalize and transform citizen engagement in democracy. Although the majority of web 2.0 systems enable these discourses to some extent, government institutions commission and manage specialized deliberation systems (information systems designed to support participative discourse) intended to promote citizen engagement. The most common examples of these are political discussio…

Abstract Information technology (IT) engagement is defined as a need to spend more time using IT. Practice-based examples show that IT engagement can have adverse effects in organizations. Although users can potentially get more work done through IT engagement, observations show that the users might jeopardize their well-being and hamper their work performance. We aimed to investigate this complexity in the research on IT engagement by examining its potential antecedents and outcomes in organizations. Considering the potentially mixed outcomes, we developed a model to examine the effects of IT engagement on personal productivity and strain. We also aimed to explain the antecedents of IT eng…
Social Network Banking : A Case Study of 100 Leading Global Banks
2018
Social media is widely recognized as a challenging new communication technology in both economic and social contexts. The present article explores how banks have exploited this technology in the range of consumer retail banking services offered by 100 leading global banks on the three major social networking sites (SNS): Facebook, Twitter, and YouTube. Viewing social network (SN) banking as a separate delivery channel and offering a working definition of SN banking, the article shows that banks have been more cautious than other businesses in using SNS. The available services are classified on nine main dimensions: marketing, financial education and advice, information support, customer sup…
Customer’s role in knowledge management and in the innovation process: effects on innovation capacity and marketing results
2016
Scholars have acknowledged customer knowledge management (CKM) as a key strategic resource for improving innovation and supporting long-term customer relationship management. This study provides a deeper understanding of the internal antecedents of business innovation capacity overcoming previous approaches. A model that had not previously been tested was used to analyse the role of customer collaboration and CKM – measured as a second-order construct – in innovation processes and marketing results. To test the model, structural equation modelling (partial least squares) was applied to a random sample of 210 Spanish companies. Results confirm that CKM and customer collaboration are antecede…
Online Density Estimation of Heterogeneous Data Streams in Higher Dimensions
2016
The joint density of a data stream is suitable for performing data mining tasks without having access to the original data. However, the methods proposed so far only target a small to medium number of variables, since their estimates rely on representing all the interdependencies between the variables of the data. High-dimensional data streams, which are becoming more and more frequent due to increasing numbers of interconnected devices, are, therefore, pushing these methods to their limits. To mitigate these limitations, we present an approach that projects the original data stream into a vector space and uses a set of representatives to provide an estimate. Due to the structure of the est…
Reverse-Safe Text Indexing
2021
We introduce the notion of reverse-safe data structures. These are data structures that prevent the reconstruction of the data they encode (i.e., they cannot be easily reversed). A data structure D is called z - reverse-safe when there exist at least z datasets with the same set of answers as the ones stored by D . The main challenge is to ensure that D stores as many answers to useful queries as possible, is constructed efficiently, and has size close to the size of the original dataset it encodes. Given a text of length n and an integer z , we propose an algorithm that constructs a z -reverse-safe data structure ( z -RSDS) that has size O(n) and answers decision and counting pattern matc…
