Extraction of the mismatch negativity elicited by sound duration decrements: A comparison of three procedures
2009
This study focuses on comparison of procedures for extracting the brain event-related potentials (ERPs) - brain responses to stimuli recorded using electroencephalography (EEG). These responses are used to study how the synchronization of brain electrical responses is associated with cognition such as how the brain detects changes in the auditory world. One such event-related response to auditory change is called mismatch negativity (MMN). It is typically observed by computing a difference wave between ERPs elicited by a frequently repeated sound and ERPs elicited by an infrequently occurring sound which differs from the repeated sounds. Fast and reliable extraction of the ERPs, such as the…
Assessing Globalization Competences in the Information Systems Domain – Instruments and Methods
2012
Stén, Tiia Assessing Globalization Competences in the Information Systems Domain – Instruments and Methods Jyväskylä: University of Jyväskylä, 2012, 36 p. Information Systems Science, Bachelor’s thesis Supervisor: Pawlowski, Jan The goal of this bachelor’s thesis is to research suitable competence assessment instruments and methods for assessing globalization competence in the Infor-mation Systems domain. Within the framework of the study, globalization competences are the skills and abilities required from an individual in order for him or her to perform effectively in an international context in the Information Systems field. The results of the analysis indicate that the most applicable c…
The impact of senior management involvement, organisational commitment and group efficacy on ITIL implementation benefits
2014
Published version of an article from the journal: Information Systems and e-Business Management. Also available from Springerlink: http://dx.doi.org/10.1007/s10257-014-0253-4 Senior management involvement, organisational commitment and group efficacy are expected to have a positive impact on Information Technology Infrastructure Library (ITIL) implementation benefits. Specifically, more involvement, commitment and efficacy should produce greater achievement. Analysing data from a survey of 446 Nordic ITIL experts, this paper examines the relationships between these predictor factors and benefits, and investigates which is most critical. This study verifies the importance of all factors, but…
Grounded theory for generating theory in the study of behavior
2012
The use of grounded theory procedures for the study of information behavior has contributed to generating theory in this field. Thirty-one works were analyzed with regard to a) their relationship to the context in which the research was carried out, b) the aspect of information behavior researched, c) the use of grounded theory procedures, and d) the generation of theory. Most of the studies were carried out in the context of health information, and grounded theory procedures were for the most part only partially applied. The theoretical propositions produced depended on the subject being studied. Although this methodology is suitable for the study of an individual's interaction with inform…
Diffusion of theories and theoretical models in the Ibero‐American research on information behavior
2021
Ibero-American research on information behavior (IB) lacks the visibility typical of other parts of the world, and little is known about it in countries outside the area. The objective of this paper has therefore been to analyze the way in which Ibero-American research incorporates various theoretical references to empirical research on IB. The results point to the existence of different focuses of research in the past 10 years, in the sense of a reduced empirical approach and a moderate to minimal use of theories in the design of such research. Furthermore, the most cited theories and models of IB at an international level are those most widely applied in this geographical area, and the us…
PASSIM – an open source software system for managing information in biomedical studies
2007
Abstract Background One of the crucial aspects of day-to-day laboratory information management is collection, storage and retrieval of information about research subjects and biomedical samples. An efficient link between sample data and experiment results is absolutely imperative for a successful outcome of a biomedical study. Currently available software solutions are largely limited to large-scale, expensive commercial Laboratory Information Management Systems (LIMS). Acquiring such LIMS indeed can bring laboratory information management to a higher level, but often implies sufficient investment of time, effort and funds, which are not always available. There is a clear need for lightweig…
The Human Context of Information Systems
2005
In its past, IS research has focused on IT and the organizations that use IT. Human issues have been studied in HCI and the Human Factor Studies of MIS. Yet recently a new wave of attention has emerged to focus more explicitly on issues rising from the human context of information systems. Studies in this area are still scattered, but there seems to exist a common paradigmatic orientation in their basic assumptions of human beings and their interaction. The end-users of information systems should be seen holistically as physical, cognitive, emotional, and social beings, whose communication is rich and uses multiple media. These views add to and improve our understanding of information and k…
Comparing Cybersecurity Information Exchange Models and Standards for the Common Secure Information Management Framework
2021
Cyber threats have increased in spite of formal economic integration in the world. Decision-makers and authorities need to respond to the growing challenge of cyberthreats by increasing cooperation. Information is one of the main facilities when the objective is to prevent hybrid threats at the EU level and between the western countries. The main purpose of the study is to find out separating and combining factors concerning existing cyber information sharing models and information management frameworks in western countries. The aim is also to find out crucial factors, which affect the utilization of a common Early Warning System for the ECHO stakeholders. The main findings are that unclear…
The serendipitous impact of COVID-19 pandemic: A rare opportunity for research and practice
2020
Highlights • The Covid-19 pandemic is a rare opportunity to examine some fundamental aspects of IM and IS research and practice. • There are at least three areas where the pandemic has impacted practice: information management, work practices and design of technologies. • The IS discipline has appropriate methods and theories to study the design of technologies and social interactions. • Concepts such as “social distancing” that has emerged in the pandemic need to be studied through philosophical premises. • The IM practices that emerge after the pandemic is over, will be shaped by how well we seize the opportunity to learn from the pandemic.
Using store level scanner data to improve category management decisions: Developing positioning maps
2009
This paper provides evidence of the usefulness of aggregated point-of-sale scanner data to infer the positioning of competing brands, providing valuable information for category management and hence facilitating decision making. Specifically, the authors propose a methodology to study the internal market structure based on market share models with latent heterogeneity when only macro-level time series data (not individual choices) are available. The proposed approach assumes a multidimensional decomposition, latent in the preference structure that is implicit to these types of models. By empirically applying this approach, the authors (1) simultaneously identify both latent dimensions of co…
