Design principles for learning analytics information systems in higher education
2020
This paper reports a design science research (DSR) study that develops, demonstrates and evaluates a set of design principles for information systems (IS) that utilise learning analytics to support learning and teaching in higher education. The initial set of design principles is created from theory-inspired conceptualisation based on the literature, and they are evaluated and revised through a DSR process of demonstration and evaluation. We evaluated the developed artefact in four courses with a total enrolment of 1,173 students. The developed design principles for learning analytics information systems (LAIS) to establish a foundation for further development and implementation of learning…
Random Slicing: Efficient and Scalable Data Placement for Large-Scale Storage Systems
2014
The ever-growing amount of data requires highly scalable storage solutions. The most flexible approach is to use storage pools that can be expanded and scaled down by adding or removing storage devices. To make this approach usable, it is necessary to provide a solution to locate data items in such a dynamic environment. This article presents and evaluates the Random Slicing strategy, which incorporates lessons learned from table-based, rule-based, and pseudo-randomized hashing strategies and is able to provide a simple and efficient strategy that scales up to handle exascale data. Random Slicing keeps a small table with information about previous storage system insert and remove operations…
Replication Data for: CNN-based People Detection in Voxel Space using Intensity Measurements and Point Cluster Flattening
2021
Dataset used to train and test a human classifier in the article "CNN-based People Detection in Voxel Space using Intensity Measurements and Point Cluster Flattening". The set contains both the raw point cloud data from an outdoor test site, as well as generated images used for training.
Cargo-Cult Containerization : A Critical View of Containers in Modern Software Development
2022
Software is increasingly developed and deployed using containers. While the concept of a container is conceptually straightforward, there are various issues to be considered while using them, ranging from technical details inside containers to the orchestration of containers that jointly form a meaningful application. In recent years, the use of containers has become so prevalent that developers have a tendency to resort to cargo-cult containerization - ritual adherence to the use of containers just because so many others are doing the same thing. In this paper, we study advantages and downsides of containers in modern-day software development. We foresee the use of containers to spread int…
Toward a Theory of Information Systems Security Behaviors of Organizational Employees: A Dialectical Process Perspective
2019
Practice-/policy-oriented abstract: Understanding why employees do or do not comply with information systems security (ISS) procedures is an imperative in today’s organizations whose futures often depend on how well they protect and harness information assets. We use a predominantly inductive approach to develop a theoretical understanding of how employees’ reasons for engaging to ISS behaviors (ISSBs) change over time, using ideas from dialectics as our scaffolding. Our dialectical view of this process suggests that explanations for engaging in different ISSBs change over time as individuals seek to balance contradictory demands. Furthermore, our view suggests that new experiences and ext…
Dialectics and contradictions in public procurement of information systems
2014
Published version of a chapter from the book M. Janssen, H. Scholl, M. Wimmer & F. Bannister (Eds.), Electronic Government : Springer Berlin Heidelberg, 2014. Also available on SpringerLink: http://dx.doi.org/10.1007/978-3-662-44426-9_24 Public procurement of Information Systems is a highly complex process. Not surprisingly, systems often fail to meet the needs for which they were procured. One of the main causes of this is the contradictions between goals of different stakeholders. Identifying and understanding these conflicts and contradictions are essential to develop strategies to improve the procurement process. In this paper, we present a case study where we examined the procurement p…
Didatext : entrer en Littérature dans un environnement informatique
1996
Le logiciel Didatext s'inscrit dans un projet qui a pour but de permettre à l'élève de contrôler le processus d'appropriation et d'exploitation de la distance esthétique entre son horizon d'attente et le texte littéraire, en subordonnant les caractéristiques ludiques de l'environnement informatique à une "immersion en littérature".
« Thyroid diseases and Controversies »
2022
The topic of the presentation is related to thyroid controversies online, specifically the Levothyrox controversy that took place in France in 2017. The objective of this work aims at performing a quantitative content analysis of online messages in order to understand how digital tools and technologies such as an online forum, shape and impact controversies.
