Perspectives on Relevance : the Relevance Test in the Constructive Research Approach
2017
Abstract Interventionist research (IVR), such as the constructive research approach (CRA), has been suggested as a method to improve the relevance of management accounting (MA) research. Although literature identifies several perspectives on relevance, the current assessment of CRA focuses on practical relevance. Moreover, an overreliance on pragmatism in assessing CRA research in the form of CRA market tests has been criticized. This article analyses the challenges inherent in conducting and assessing CRA research, both conceptually and with a CRA case example. In order to overcome these possible CRA challenges, we suggest analyzing CRA relevance from multiple perspectives. The perspective…
Students evaluating Internet sources – From versatile evaluators to uncritical readers
2008
The Internet is a significant information resource for students due to the ease of access it allows to a vast amount of information. As the quality of the information on the Internet varies, it is important that students are able to evaluate such information critically. The aim of the study was to investigate how students evaluate Internet sources in an authentic learning task. Upper secondary school students ( n = 25) were asked to look for source material on the Internet in order to write an essay. They were asked to verbalize their thoughts during the material gathering process. Their verbalizations and actions on the Internet were recorded and analyzed. The five evaluation profiles eme…
Serendipity in recommender systems
2018
The number of goods and services (such as accommodation or music streaming) offered by e-commerce websites does not allow users to examine all the available options in a reasonable amount of time. Recommender systems are auxiliary systems designed to help users find interesting goods or services (items) on a website when the number of available items is overwhelming. Traditionally, recommender systems have been optimized for accuracy, which indicates how often a user consumed the items recommended by system. To increase accuracy, recommender systems often suggest items that are popular and suitably similar to items these users have consumed in the past. As a result, users often lose interest…
Challenges of Serendipity in Recommender Systems
2016
Most recommender systems suggest items similar to a user profile, which results in boring recommendations limited by user preferences indicated in the system. To overcome this problem, recommender systems should suggest serendipitous items, which is a challenging task, as it is unclear what makes items serendipitous to a user and how to measure serendipity. The concept is difficult to investigate, as serendipity includes an emotional dimension and serendipitous encounters are very rare. In this paper, we discuss mentioned challenges, review definitions of serendipity and serendipity-oriented evaluation metrics. The goal of the paper is to guide and inspire future efforts on serendipity in r…
Dialogic journalism : how can journalists participate in the networks of social innovation?
2017
This thesis asks the question “What is the role of journalism in social innovation?” It explores how journalism is redefined when it engages in the creation of “the new” in society. The study analyzes four cases of journalism-related social innovation in two countries – the USA and Finland: a contentious national media event; crowdsourcing for legislation; a series of dialogic innovation workshops in Finland; an environment of data-based civic innovation in the USA. Social innovation is defined as innovations that work in meeting social goals. In literature and the contemporary discussion on the crisis of journalism, innovation is required to restore journalisms’ legitimacy and financial su…

Legitimacy and relevance of a performance measurement system in a Finnish public-sector case
2019
Purpose This study investigates the difficulties involved in translating stakeholder expectations into action and maintaining legitimacy through the use of a performance measurement system (PMS) created in a Finnish regional development company (RDC). This longitudinal case study illustrates the fluctuating and socially constructed nature of legitimacy in the public sector. Design/methodology/approach This qualitative case study longitudinally analyzes the various developments occurring during and after the development of a PMS system for the case organization. Empirical data include interviews, workshops, observation and other materials relating to the case organization. Findings The init…
Cost Management in the Public Sector : Legitimation Behaviour and Relevant Decision Making
2016
This paper presents a case study where a cost management project was implemented using action research methodology at two Finnish organizations working in a purchaser–provider relationship. While the study demonstrates the efficiency-seeking motive behind the implementation of the management accounting tool, subsequent investigation found that tool remained partly unused despite showing its potential relevance for practice through user involvement. However, this does not necessarily signal legitimation-seeking behaviour. Reasons for not using some parts of the tool point to an overestimation of the functionality and an underestimation of implementation problems during the design process. Th…
