In this study, we compared the impact of audio-, video-, and text-chat interaction on target language use during online learner-learner interaction and on learner affect amongst adolescent learners of German as a foreign language. Repeated measures and ANOVA analyses revealed a high percentage of target language output in all conditions for all four tasks, especially in text- chat. Audio-chatters produced the most output and used the most meaning negotiation, compensation strategies, self-repair and other-repair strategies. Learners in all conditions gained in enjoyment, willingness to communicate and self-efficacy. Anxiety reduced for text-chatters. Task effects partly determined the quantity of L2 output, while condition effects determined meaning-oriented and form-focused processing.

Robots need sensors to operate properly. Using a single image sensor, various aspects of a robot operating in its environment can be measured or monitored. Over the past few years, image sensors have improved a lot: frame rate and resolution have increased, while prices have fallen. As a result, data output has increased and in a number of applications data transfer to a processing unit has become the limiting factor for performance. Local processing in the sensor is one way of reducing data transfer. A report on the Vision in Robotics and Mechatronics project
Hedonic (happiness) and eudaimonic (meaning in life) well-being are negatively related to depressive symptoms. Genetic variants play a role in this association, reflected in substantial genetic correlations. We investigated the overlap and differences between well-being and depressive symptoms, using results of Genome-Wide Association studies (GWAS) in UK Biobank. Subtracting GWAS summary statistics of depressive symptoms from those of happiness and meaning in life, we obtained GWASs of respectively “pure” happiness (neffective = 216,497) and “pure” meaning (neffective = 102,300). For both, we identified one genome-wide significant SNP (rs1078141 and rs79520962, respectively). After subtraction, SNP heritability reduced from 6.3% to 3.3% for pure happiness and from 6.2% to 4.2% for pure meaning. The genetic correlation between the well-being measures reduced from 0.78 to 0.65. Pure happiness and pure meaning became genetically unrelated to traits strongly associated with depressive symptoms, including loneliness, and psychiatric disorders. For other traits, including ADHD, educational attainment, and smoking, the genetic correlations of well-being versus pure well-being changed substantially. GWAS-by-subtraction allowed us to investigate the genetic variance of well-being unrelated to depressive symptoms. Genetic correlations with different traits led to new insights about this unique part of well-being. Our results can be used as a starting point to test causal relationships with other variables, and design future well-being interventions.

One of the mission-driven innovation policies of the Netherlands is energy transition which sets, among others, the challenge for a carbon-neutral built environment in 2050. Around 41% of Dutch houses do not yet have a registered energy label, and approximately 31% of the registered houses have label C or lower. This calls for action within the housing renovation industry. Bound to the 70 percent rule, a renovation plan requires full (or at least 70 percent) agreement on the renovation between relevant parties, including residents. In practice, agreement indicators focus mostly on economic and energy aspects. When indicators include people’s needs and preferences, it is expected to speed participation and agreement, increasing residents’ satisfaction and enhances the trust in public institutions. Tsavo was founded in 2015 to organise the sustainability of buildings for ambitious clients. Its sustainability process aims to accelerate renovation by keeping at their core value the social needs and preferences of residents. In this project Tsavo and TU Delft work together to optimise the sustainability process so, it includes everyone’s input and results in a sustainability plan that represents everyone. Tsavo’s role will be key in keeping the balance between both a sustainable renovation service that is cheaper and fast yet also attractive and with an impact on the quality of living. In this project, Tsavo’s sustainable renovation projects will be used to implement methods that focus on increasing participation and residents’ satisfaction. TU Delft will explore principles of attractive, accessible and representative activities to stimulate residents to decide on a renovation plan that is essential and meaningful to all.
The SPRONG-collaboration “Collective process development for an innovative chemical industry” (CONNECT) aims to accelerate the chemical industry’s climate/sustainability transition by process development of innovative chemical processes. The CONNECT SPRONG-group integrates the expertise of the research groups “Material Sciences” (Zuyd Hogeschool), “Making Industry Sustainable” (Hogeschool Rotterdam), “Innovative Testing in Life Sciences & Chemistry” and “Circular Water” (both Hogeschool Utrecht) and affiliated knowledge centres (Centres of Expertise CHILL [affiliated to Zuyd] and HRTech, and Utrecht Science Park InnovationLab). The combined CONNECT-expertise generates critical mass to facilitate process development of necessary energy-/material-efficient processes for the 2050 goals of the Knowledge and Innovation Agenda (KIA) Climate and Energy (mission C) using Chemical Key Technologies. CONNECT focuses on process development/chemical engineering. We will collaborate with SPRONG-groups centred on chemistry and other non-SPRONG initiatives. The CONNECT-consortium will generate a Learning Community of the core group (universities of applied science and knowledge centres), companies (high-tech equipment, engineering and chemical end-users), secondary vocational training, universities, sustainability institutes and regional network organizations that will facilitate research, demand articulation and professionalization of students and professionals. In the CONNECT-trajectory, four field labs will be integrated and strengthened with necessary coordination, organisation, expertise and equipment to facilitate chemical innovations to bridge the innovation valley-of-death between feasibility studies and high technology-readiness-level pilot plant infrastructure. The CONNECT-field labs will combine experimental and theoretical approaches to generate high-quality data that can be used for modelling and predict the impact of flow chemical technologies. The CONNECT-trajectory will optimize research quality systems (e.g. PDCA, data management, impact). At the end of the CONNECT-trajectory, the SPRONG-group will have become the process development/chemical engineering SPRONG-group in the Netherlands. We can then meaningfully contribute to further integrate the (inter)national research ecosystem to valorise innovative chemical processes for the KIA Climate and Energy.
Bij de ontwikkeling van kinderen speelt de omgeving waarin zij opgroeien en de wijze waarop zij zich verbonden voelen met hun buurt een belangrijke rol (Owens, 2004; 2016). Om als basisschool goed bij te kunnen dragen aan de ontwikkeling van kinderen is het van belang dat scholen de omgeving en de buurt waarin hun leerlingen opgroeien kennen en kunnen benutten voor hun onderwijs. In het bijzonder gaat het daarbij om de betekenis die deze omgeving voor hun leerlingen heeft. Voor basisscholen in wijken met een grote diversiteit aan inwoners kan de betekenis van eenzelfde omgeving voor verschillende leerlingen ook zeer verschillend zijn. Naar de wijze waarop kinderen zich verbonden voelen met de fysieke en sociale ruimte is nog weinig onderzoek gedaan (Tani, 2016). Naast inzicht in de bestaande verbinding van kinderen met hun omgeving is het voor het onderwijs belangrijk om inzicht te verkrijgen in de wijze waarop kinderen in staat kunnen worden gesteld om zich te binden aan een plek en om deze plek te benutten bij hun ontwikkeling. De capability approach (Nussbaum, 2014) en een perspectief op de veerkracht van kinderen (Enthoven, 2007) bieden een kader om naar dit vraagstuk te kijken. Het onderzoek richt zich op wat het primair onderwijs kan doen om de aan de omgeving gerelateerde vermogens van kinderen te ontwikkelen. Onderwijs waarin de leefomgeving van kinderen wordt betrokken of waarin de leefomgeving op enige wijze een rol speelt kan hiertoe een middel zijn. Dit vanuit de notie dat door het ontwikkelen van een ‘sense of place’ (Dolan, 2016) de kennis, persoonlijke verbondenheid en verantwoordelijkheid voor de lokale omgeving versterkt kunnen worden. Het onderzoek zal na een verkennende fase een ontwerpgericht karakter krijgen, waarbij op onderzoeksmatige wijze materiaal wordt ontwikkeld dat bruikbaar is op basisscholen en lerarenopleidingen basisonderwijs.
