Automatic crack detection results using a novel device for survey and analysis of road pavement condition
2019
To accurately schedule maintenance operations, it is crucial to monitor the pavement state and, thus, evaluate the structural and functional indices during its entire service life. In particular, surface conditions (cracks, potholes, patches, rutting, etc.) must be properly checked – especially in terms of detection, identification, and classification of distresses – for avoiding reaching dangerous values for users (overpassing safety thresholds). However, monitoring and survey activities can be so costly (not only in economic terms, but further considering the execution time) to discourage their execution, with evident drawbacks for a proper maintenance management and the related intervent…
Do you know what you are reading for? Exploring the effects of a task model enhancement on fifth graders' purposeful reading
2021
International audience; Background: Drawing on theories of purposeful reading, this study explored task conditions that support fifth graders' selective reading of documents in order to answer questions. More specifically, we investigated whether promoting students' elaboration of their task model increases task performance. Methods: Participants had to answer series of questions by searching documents for the relevant information. Half the participants received a task model prompt, and half received a control prompt. Participants' eye movements were recorded during text search, in order to investigate more precisely the effect of an enhanced task model. Results: Participants provided more …
“You really brought all your feelings out” – Scaffolding students to identify the socio-emotional and socio-cognitive challenges in collaborative lea…
2021
Abstract The aim of this study is to explore how students experience and describe socio-cognitive and socio-emotional challenges in collaborative learning. The participants (N = 20) were teacher education students whose collaborative learning was supported with a designed regulation macro script during a six-week mathematics course. The purpose of the script was to provide structured phases during the collaborative learning tasks for the group members to plan, monitor, and evaluate their workings. The video data of groups' face-to-face work was collected and analysed by focusing on the different types of challenges the groups experienced and the types of challenges they described during the…
The development of achievement strategies and academic skills during the first year of primary school
2002
Abstract The aim of the study was to investigate whether children's achievement strategies would predict the development of their reading and mathematical skills during the first school year, or whether it is rather these skills that predict the changes in their achievement strategies. One-hundred and five 6- to 7-year-old children were examined three times during their first year of primary school: in each measurement, their self-reported achievement strategies were assessed, and their reading and mathematical skills were rated by their classroom teacher. Their overall cognitive competence was also measured before entry into school. The results showed that the use of maladaptive achievemen…
Enabling Sociability When Using Virtual Reality Applications : A Design Science Research Approach
2019
Immersive virtual reality applications aim at providing an all-encompassing spatial experience where a user can feel like being in another world or dimension. The systems are inherently designed for individual use as the devices disconnect the user from the physical environment. However, the applications are seldom used alone. Specifically, when used for sales and marketing, the user often needs help from other people but also benefits from social interaction as a part of the experience. Design research methodology is applied to three iterative development versions of a virtual-reality application. The focus of the evaluation of the artifacts is in the social use emphasizing three sociabili…
Problem Space Identification for Developing Virtual Reality Learning Environments
2021
Our study argues that the extant literature on virtual reality-based learning environments (VRLEs) currently lacks proper definitions and context descriptions for a problem space, which is fundamental for conducting design science research (DSR). Without properly conducted problem space identification, the most pivotal problems cannot be identified resulting solutions lacking validity and unreliable evaluations. This is a major challenge for the DSR in the educational field, but also for the research on VRLEs. The purpose of this paper is to introduce a novel DSR method to support rigorous problem space identification, which would allow rigorous and profound problem space analysis. The inst…
Innovation Policies for Regional Structural Change: Combining Actor-Based and System-Based Strategies
2018
This chapter analyses opportunities and challenges for regional innovation policies designed to promote new path development in different types of regional innovation systems (RISs). RISs differ enormously in their capacity to develop new growth paths due to pronounced differences in endogenous potentials and varying abilities to attract and absorb exogenous sources for new path development. We distinguish between different types of regional industrial path development, which reflect various degrees of radicalness of regional structural change. The chapter offers a conceptual analysis of conditions and influences that enable and constrain new path development in different types of RISs and …
From job demands and resources to work engagement, burnout, life satisfaction, depressive symptoms, and occupational health
2016
This study investigated the cross-lagged associations between work engagement and burnout, and life satisfaction and depressive symptoms, their demands (i.e., workload) and resources (i.e., servant leadership, self-efficacy, resilience) and relationships with occupational health outcomes (i.e., recovery, number of mental health diagnoses, workaholism). This study is a part of an ongoing Occupational Health Study in which 1 415 employees (586 men, 829 women) were followed twice during two years 2011–12 through their occupational health services. The participants filled in a questionnaire on their work engagement, burnout symptoms, well-being, personal and work environmental resources and dem…
From omniscient narrator to involved participants: Places and spaces “activated” in the EHEC O104:H4 crisis 2011
2020
Crisis management is often conceived from the position of an omniscient narrator, albeit the general consensus that crises are subjectively interpreted and experienced. The paper makes an analytical attempt to de-homogenize the notion of crisis. We argue that the perception of crises differs and present a spatial perspective on crisis to foreground the positionality of different actor groups. By referring to the EHEC outbreak 2011 in Germany, we explore two spatial configurations that seem to be of particular relevance: territories embedded in a nested hierarchy and topologies of interconnected places. State authorities think and act strongly in terms of territorial borders and along sector…
Inattention and Uncertainty in the Predictive Brain
2021
Negative effects of inattention on task performance can be seen in many contexts of society and human behavior, such as traffic, work, and sports. In traffic, inattention is one of the most frequently cited causal factors in accidents. In order to identify inattention and mitigate its negative effects, there is a need for quantifying attentional demands of dynamic tasks, with a credible basis in cognitive modeling and neuroscience. Recent developments in cognitive science have led to theories of cognition suggesting that brains are an advanced prediction engine. The function of this prediction engine is to support perception and action by continuously matching incoming sensory input with to…
