Un “ chef d’orchestre” ? Le PSU en mai-juin 1968

2019

En juillet 1968, la Direction centrale des renseignements généraux (DCRG) consacre un long rapport aux événements qui ont secoué le pays depuis mai. Elle y passe en revue les différentes organisations suspectées d’avoir joué un rôle subversif et pose le PSU en « chef d’orchestre », avant de pointer le rôle particulièrement trouble de Marc Heurgon. On peut s’esclaffer et ironiser sur la propension des Renseignements généraux à chercher des complots lorsqu’il doit faire face à des mouvements so...

Seeking Technical Debt in Critical Software Development Projects : An Exploratory Field Study

2016

In recent years, the metaphor of technical debt has received considerable attention, especially from the agile community. Still, despite the fact that agile practices are increasingly used in critical domains, to the best of our knowledge, there are no studies investigating the occurrence of technical debt in critical software development projects. The results of an exploratory field study conducted across several projects reveal that a variety of business and environmental factors cause the occurrence of technical debt in critical domains. Using Grounded Theory method, these factors are categorized as ambiguity of requirement, diversity of projects, inadequate knowledge management, and res…

Supporting Agile Development by Facilitating Natural User Interaction with Executable Formal Specifications

2011

Agile development benefits from fast feedback from various stakeholders. If implemented in a suitable way, formal methods can enhance the agile development process. With an executable formal specification, it is possible to analyse and simulate the behaviour of the target system before it is being built. However, for the users' and developers' natural participation in the development process, it is necessary to use a real end-user interface and bind it to the execution environment being used in the simulations and animations. This requires, though, that the execution model used to simulate the specification is appropriately changed to facilitate the use of these user interfaces. The authors…

Consumers’ adoption of information services

2013

This paper reports on a design science research study that seeks to investigate how information service components affect consumers’ potential adoption of such services. More specifically, the paper develops a conceptual model that uses the theory of organizational information services (TOIS) and the unified theory of acceptance and use of technology (UTAUT) as a basis. The results indicate that individual constructs can be linked to service components. In turn, this result can potentially be instrumental in progress toward a deeper understanding of consumers’ adoption of information services and how this affects the development of such services and systems that support them.

Consumer Acceptance and Use of Instagram

2016

This study extends the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model to investigate factors affecting the acceptance and use of a social networking service (SNS) called Instagram. The UTAUT2 model is modified to better suit the context of SNSs by replacing the price value construct with self-congruence. Furthermore, we explore the effects of behavioral intention and use behavior on "user indegree" defined as the number of people who follow an SNS user. The results of the survey study largely support the hypothesized model in the context of Instagram. The findings contribute to previous knowledge by demonstrating the important roles of hedonic motivation and habit in co…

Domain Specific Case Tool for ICT-Enabled Service Design

2014

One major problem in service design is the limited availability of information gathered during the development process. In particular, information on end-user requirements is difficult for designers, developers, and maintainers to access. Here, we provide a mechanism that supports the gathering and modeling of various types of information throughout the service and software development life cycle. As various existing tools focus on a particular part of the life cycle, essential information is not available, or it is more difficult to obtain in later stages. The linkage between information collected in the different stages is often lost. The implemented tool support enables the modeling of r…

Internet Adoption at the User Level: Empirical Evidence from The Gambia

2014

The unified theory of acceptance and use of technology (UTAUT) are used to investigate technology adoption. However, its application in Sub-Saharan Africa is rare and barely extended to the validation phase. In this paper, we introduce six new moderating factors for UTAUT core determinants and two other direct determinants of Internet adoption. The objective of this approach is to identify relevant elements of Internet adoption at the user level in The Gambia. Moderating factors are interacting terms used when the relationship between independent and dependent variable is weak, inconsistent or non-existent. A case study research design was employed and the data were gathered in Autumn of 20…

User expectations, use experiences and continued adoption of a mobile secure communication application

2018

The importance of secure communication between employees in enterprises and governmental organizations as well as technologies to support that has increased tremendously over the past years. This study examines the user expectations before and the use experiences during the implementation phase of a mobile secure communication application together with expectation–confirmation and its influence on continued adoption. The study is explorative in nature and empirically based on thematic analysis of qualitative data collected from pilot users of a mobile secure communication application who work in a governmental organization in Finland. The theoretical basis of the study draws from two well-e…

L’unificazione della segnaletica stradale verticale nell’ambito dell’Unione Europea: un’applicazione ai segnali di pericolo

2010

La presente memoria illustra la metodologia ed i risultati di un’attività di ricerca finalizzata a studiare il problema dell’unificazione europea dei sistemi di segnaletica stradale verticale, la quale rappresenta uno dei presupposti fondamentali per favorire la crescita dei livelli di efficienza e sicurezza della mobilità delle persone e delle merci in ambito UE. Nella prima fase di tale studio, i cui risultati sono riportati in questo articolo, l’attenzione è stata focalizzata sui cartelli stradali di pericolo, utilizzando una base dati relativa a 19 Stati membri dell’Unione Europea. I set di segnali di pericolo di questi Paesi sono stati confrontati tramite un’analisi a molti criteri, ba…
