Dr. Scott Allison and Dr. Al Goethals – Faculty Author Interview
No full textDr. Scott Allison, Professor, Department of Psychology and Dr. Al Goethals, Professor, Jepson School of Leadership Studies discuss their recent book, Heroes: What They Do and Why We Need Them. Published by Oxford University Press, the book offers a stimulating tour of the psychology of heroism, shedding light on what heroism and villainy mean to most people and why heroes — both real people and fictional characters — are so vital to our lives.

On the Theory of Zm Linear Codes: the Zm Linear Preparata and Goethals Codes for m>2
No full textLet m ∈ N and Zm def/ ={0,1, ⋯, m-1} be the m ary alphabet. A Zm linear code of length n ∈ N is a submodule of the module (Zmn,+mod m, Zm, · bmod m). This paper presents a significant lower bound for the minimum Lee distance dLee (C), of any Zm linear code C. This bound facilitates, for a given minimum Lee distance, the efficient design of high information rate codes, which are computationally simple to implement using algebraic operations over fields of small cardinality. Two notable examples of such codes are provided, demonstrating the application of this bound. These families of codes generalize the Z4 linear Preparata and Goethals codes over the alphabet Zm, m=2l ∈ N with l ≥ 2. Specifically, for any m=2l>2 and h ∈ N, h odd, the generalized Zm linear Preparata codes have length n+1=2h, minimum Lee distance 6 and cardinality |C|=mn-h-1⌈ m / 4⌉h⌈ m / 8⌉. For the same parameters m, l, n, h ∈ N, the generalized Zm linear Goethals codes have length n+1=2h, minimum Lee distance 8 and cardinality |C|=mn-2 h-1⌈ m / 2⌉h⌈ m / 4⌉h⌈ m / 8⌉. Notably, both families of codes are less redundant and less complex than m-ary codes with the same minimum Lee distances obtained by applying the Gray mapping to l-bit subblocks of codewords from binary linear codes
Using social network data to predict technology acceptance
No full textIn contrast to popular literature on technology acceptance, this research-in-progress paper does not intend to build an explanatory model of technology acceptance but a predictive model so as to predict whether a specific person is likely to accept some technology. We show that the constructs that were identified in the classic UTAUT (such as performance expectancy, effort expectancy and social influence) can be used in a predictive model but that better predictions of system use can be made using knowledge about social networks that exist between people. Both social influence and social selection data are valuable to make predictions. Our approach is tested in the context of a video system which is part of an online learning platform, using a sample of 133 interconnected students
Emotionele impact van de chronische ziekte op het kind en zijn gezin
No full textEmotionele impact van de chronische ziekte op het kind en zijn gezin
Een chronische ziekte heeft een impact op het emotioneel welbevinden van het opgroeiende kind, de jongere, jongvolwassene en zijn gezin. De behandeling omhelst veelal intensieve dagelijkse opvolging. Therapietrouw (de mate waarin patiënten hun voorgeschreven behandeling volgen zoals met het behandelend team overeengekomen; WHO, 2003) is een complex gegeven. In deze bijdrage worden de resultaten besproken van een omvattend Vlaams onderzoek rond therapietrouw bij kinderen en jongeren met type 1 diabetes (N=291) waarin zowel jongeren als hun beide ouders werden bevraagd (Goethals et al., 2017). Er zal vooral worden ingezoomd op de belangrijke rol van de onderliggende opvoedingsdimensies (responsiviteit, psychologische controle etc.) die ouders hanteren. Er wordt ingegaan op de werkzame factoren in de behandeling en begeleiding door de psycholoog, onder meer gebaseerd op de Zelfdeterminatietheorie (Ryan & Deci, 2000; Vansteenkiste & Soenens, 2015).

Model-Based Reinforcement Learning with State Abstraction: A Survey
No full textModel-based reinforcement learning methods are promising since they can increase sample efficiency while simultaneously improving generalizability. Learning can also be made more efficient through state abstraction, which delivers more compact models. Model-based reinforcement learning methods have been combined with learning abstract models to profit from both effects. We consider a wide range of state abstractions that have been covered in the literature, from straightforward state aggregation to deep learned representations, and sketch challenges that arise when combining model-based reinforcement learning with abstraction. We further show how various methods deal with these challenges and point to open questions and opportunities for further research.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Interactive IntelligencePattern Recognition and Bioinformatic

No full textk-Point semidefinite programming bounds for equiangular lines
No full textWe propose a hierarchy of k-point bounds extending the Delsarte–Goethals–Seidel linear programming 2-point bound and the Bachoc–Vallentin semidefinite programming 3-point bound for spherical codes. An optimized implementation of this hierarchy allows us to compute 4, 5, and 6-point bounds for the maximum number of equiangular lines in Euclidean space with a fixed common angle.Discrete Mathematics and Optimizatio
