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…
Towards the Design of Respond Action in Disaster Management Using Knowledge Modeling
2017
This position paper highlights current problems linked to the aspects of the multi-agency collaboration during disaster response. The coordination and cooperation depend on the information sharing and use which must face up to interoperability, access rights, and quality problems. The research project aims at providing an assessment of information impact on the disaster response in order to support the decision-making about what information shared or what quality of data used to improve the response efficiency. Our research approach propose to combine an information system able to integrate heterogeneous data and a simulation system to assess different strategies of information sharing, dis…
A Framework for Software Risk Management
1996
We present a simple, but powerful framework for software risk management. The framework synthesizes, refines, and extends current approaches to managing software risks. We illustrate its usefulness through an empirical analysis of two software development episodes involving high risks. The framework can be used as an analytical device to evaluate and improve risk management approaches and as a practical tool to shape the attention and guide the actions of risk managers.
Implementing IT Service Management: A systematic literature review
2013
Author's version of an article in the journal: International Journal of Information Management. Also available from the publisher at: http://dx.doi.org/10.1016/j.ijinfomgt.2013.01.004 This article provides a systematic review of existing research related to the implementation of IT Service Management (ITSM) and the Information Technology Infrastructure Library (ITIL). The review's main goals are to support research; to facilitate other researchers' search for relevant studies; and to propose areas for future studies within this area. In addition, we provide IT managers with useful information on ITSM and ITIL, based on research-based knowledge of their implementation. The review results sug…
Using organizational influence processes to overcome IS implementation barriers: lessons from a longitudinal case study of SPI implementation
2014
A fundamental tenet of the information systems (IS) discipline holds that: (a) a lack of formal power and influence over the organization targeted for change, (b) weak support from top management, and (c) organizational memories of prior failures are barriers to implementation success. Our research, informed by organization influence, compellingly illustrates that such conditions do not necessarily doom a project to failure. In this paper, we present an analysis of how an IS implementation team designed and enacted a coordinated strategy of organizational influence to achieve implementation success despite these barriers. Our empirical analysis also found that technology implementation and …
Errors and Complications in SQL Query Formulation
2018
SQL is taught in almost all university level database courses, yet SQL has received relatively little attention in educational research. In this study, we present a database management system independent categorization of SQL query errors that students make in an introductory database course. We base the categorization on previous literature, present a class of logical errors that has not been studied in detail, and review and complement these findings by analyzing over 33,000 SQL queries submitted by students. Our analysis verifies error findings presented in previous literature and reveals new types of errors, namely logical errors recurring in similar manners among different students. We…
Privacy preserving mechanisms for enforcing security and privacy requirements in E-health solutions
2016
In the last few decades, there have been significant efforts in integrating information and communication technologies (ICT) into healthcare practices. This new paradigm commonly identified as electronic healthcare (e-health) allows provisioning of healthcare services at an affordable price to its consumers. However, there have been questions raised about the security of the sensitive information such as health records as well as the privacy of involving parties raising doubts on the minds of the general public. Thus, it is important to understand the potential security challenges in e-health systems and successfully resolve them by taking adequate measures to ensure fair utilization of suc…
ECCOLA : a method for implementing ethically aligned AI systems
2021
Artificial Intelligence (AI) systems are becoming increasingly widespread and exert a growing influence on society at large. The growing impact of these systems has also highlighted potential issues that may arise from their utilization, such as data privacy issues, resulting in calls for ethical AI systems. Yet, how to develop ethical AI systems remains an important question in the area. How should the principles and values be converted into requirements for these systems, and what should developers and the organizations developing these systems do? To further bridge this gap in the area, in this paper, we present a method for implementing AI ethics: ECCOLA. Following a cyclical action res…
