Current status of the TSensor systems roadmap - Walsh, Steven
We apply our work from the contemporary pharmaceutical industry to generate a third generation-style technology roadmap for TSensor Systems. First we identify drivers and consortia. We then identify relevant technology components, namely multiple root technologies, multiple unit cells, multiple critical dimensions, strict boundary conditions constraining innovations and products, a heightened importance of drivers, and a more prominent role for consortia. These components include chips and nanogenerators, enhanced lithium ion batteries and supercapacitors, and standards and protocols. We also identify the Technology Readiness Levels (TRL) of those components. The overall TRL for the TSensor Systems landscape is 4/9, “Component and/or breadboard...
ADAPTER: Analysing & Developing Adaptability & performance in Teams to enhance resilience - Beek, Dolf (F.A.) van der; Schraagen, Jan Maarten
In the current study, the concept of team resilience was operationalized by developing a first version of a questionnaire (ADAPTER) driven by the four essential abilities of resilience (Hollnagel, 2011) and expanded with more relation-oriented abilities of leadership and cooperation. The development and administration of ADAPTER took place within two companies. Factor analyses using data of 91 participants largely supported the hypothesized 6-dimension taxonomy. Support was found for Team responding behavior, Shared Leadership and Cooperation with other teams/ departments. Anticipation showed considerable overlap with the Monitoring scale, possibly due to the fact that monitoring items dealt with prospective situations. Using...
Teachers' knowledge sharing: a study on the influence of work engagement, occupational self-efficacy and Human Resources Management on knowledge sharing - Vermeulen, M.; Runhaar, P.; Konermann, J.; Sanders, Karin
Knowledge sharing is one of the professionalizetion processes and is an important factor in the competition between organizations and for innovation processes to sustain. In this study the central theme is the way knowledge sharing is affected by occupational self-efficacy (OSE), work engagement and High Commitment HRM (HC-HRM). In investigating these relations the AMO framework is used. The research data were obtained by 126 teachers from one secondary school. However from the regression analyses it was learned that the relationship between the variables OSE, HC HRM and work engagement with knowledge sharing was more complex than expected. Additional analyses by...
Working mechanism of a multidimensional computerized adaptive test for fatigue in rheumatoid arthritis - Nikolaus, Stephanie; Bode, Christina; Taal, Erik; Vonkeman, Harald E.; Glas, Cees A.W.; Laar, Mart A.F.J. van de
This paper demonstrates the mechanism of a multidimensional computerized adaptive test (CAT) to measure fatigue in patients with rheumatoid arthritis (RA). A CAT can be used to precisely measure patient-reported outcomes at an individual level as items are consequentially selected based on the patient’s previous answers. The item bank of the CAT Fatigue RA has been developed from the patients’ perspective and consists of 196 items pertaining to three fatigue dimensions: severity, impact and variability of fatigue.
The CAT Fatigue RA was completed by fifteen patients. To test the CAT’s working mechanism, we applied the flowchart-check-method. The adaptive item selection...
Modeling habitual and addictive smartphone behavior: The role of smartphone usage types, emotional intelligence, social stress, self-regulation, age, and gender - Deursen, Alexander J.A.M. van; Bolle, Colin L.; Hegner, Sabrina M.; Kommers, Piet A.M.
The present study investigates the role of process and social oriented smartphone usage, emotional intelligence, social stress, self-regulation, gender, and age in relation to habitual and addictive smartphone behavior. We conducted an online survey among 386 respondents. The results revealed that habitual smartphone use is an important contributor to addictive smartphone behavior. Process related smartphone use is a strong determinant for both developing habitual and addictive smartphone behavior. People who extensively use their smartphones for social purposes develop smartphone habits faster, which in turn might lead to addictive smartphone behavior. We did not find an influence of emotional intelligence on...
Exploring teachers' use of TPACK in design talk: The collaborative design of technology-rich early literacy activities - Boschman, Ferry; Mckenney, Susan; Voogt, Joke
Research shows the benefits of collaborative design activity by teachers are that in their conversations (design talk) they develop technological pedagogical content knowledge (TPACK). While more and more teachers engage in collaborative design, little is known about how they use TPACK during design. The main question of this study was: “What is the nature of design talk of a group of teachers during the design of technology-rich early literacy activities?” Using a holistic case study on design talk, the analysis focused on the topics that were under discussion and how these topics were discussed. Three phases of coding were applied:...
Approximations for the waiting-time distribution in an M/P H/c priority queue - Al Hanbali, A.M.; Alvarez, E.M.; Heijden, M.C. van der
We investigate the use of priority mechanisms when assigning service engineers to customers as a tool for service differentiation. To this end, we analyze a non-preemptive M/PH/c priority queue with various customer classes. For this queue, we present various accurate and fast methods to estimate the first two moments of the waiting time per class given that all servers are occupied. These waiting time moments allow us to approximate the overall waiting time distribution per class. We subsequently apply these methods to real-life data in a case study.
