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.

This study assessed the effect of visitors' personality and emotional response on finding positive meaning in life and the intention to spread positive word of mouth. The sample (n = 260) consists of visitors to Sachsenhausen Memorial and Museum near Berlin. Findings indicate that the emotion of interest positively contributes to finding positive meaning in life and positive word of mouth. The effects of personality are marginal. Personality explains little of the variance in positive meaning and positive word of mouth. Emotional response accounts for 25% of the variance in finding positive meaning in life-in terms of finding personal benefit from the visit, controlled for personality. Despite the dominant negative emotional response, tourists find positive meaning in their visit. These findings correspond with those observed in studies on personal trauma and loss. Positive meaning could potentially contribute to adjustment processes to cope with what occurred. Future research should include address longer term effects on postvisit behavior.

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.
In order to stay competitive and respond to the increasing demand for steady and predictable aircraft turnaround times, process optimization has been identified by Maintenance, Repair and Overhaul (MRO) SMEs in the aviation industry as their key element for innovation. Indeed, MRO SMEs have always been looking for options to organize their work as efficient as possible, which often resulted in applying lean business organization solutions. However, their aircraft maintenance processes stay characterized by unpredictable process times and material requirements. Lean business methodologies are unable to change this fact. This problem is often compensated by large buffers in terms of time, personnel and parts, leading to a relatively expensive and inefficient process. To tackle this problem of unpredictability, MRO SMEs want to explore the possibilities of data mining: the exploration and analysis of large quantities of their own historical maintenance data, with the meaning of discovering useful knowledge from seemingly unrelated data. Ideally, it will help predict failures in the maintenance process and thus better anticipate repair times and material requirements. With this, MRO SMEs face two challenges. First, the data they have available is often fragmented and non-transparent, while standardized data availability is a basic requirement for successful data analysis. Second, it is difficult to find meaningful patterns within these data sets because no operative system for data mining exists in the industry. This RAAK MKB project is initiated by the Aviation Academy of the Amsterdam University of Applied Sciences (Hogeschool van Amsterdan, hereinafter: HvA), in direct cooperation with the industry, to help MRO SMEs improve their maintenance process. Its main aim is to develop new knowledge of - and a method for - data mining. To do so, the current state of data presence within MRO SMEs is explored, mapped, categorized, cleaned and prepared. This will result in readable data sets that have predictive value for key elements of the maintenance process. Secondly, analysis principles are developed to interpret this data. These principles are translated into an easy-to-use data mining (IT)tool, helping MRO SMEs to predict their maintenance requirements in terms of costs and time, allowing them to adapt their maintenance process accordingly. In several case studies these products are tested and further improved. This is a resubmission of an earlier proposal dated October 2015 (3rd round) entitled ‘Data mining for MRO process optimization’ (number 2015-03-23M). We believe the merits of the proposal are substantial, and sufficient to be awarded a grant. The text of this submission is essentially unchanged from the previous proposal. Where text has been added – for clarification – this has been marked in yellow. Almost all of these new text parts are taken from our rebuttal (hoor en wederhoor), submitted in January 2016.
Binnen het huidige muziekaanbod voor ouderen zijn veel praktijken gericht op woonzorg- en verpleeghuizen. Het grootste deel van de kwetsbare ouderen woont echter thuis. Vanuit de gedachte dat muziek een katalysator kan zijn voor welzijn en welbevinden, wordt met Dichtbij met Muziek een nieuwe innovatieve muziekpraktijk geïnitieerd waarbij professionele musici op maat muziek maken voor kwetsbare ouderen die (nog) thuis wonen en hun mantelzorgers. De uitbraak van de corona-pandemie zorgde ervoor dat de praktijk uiteindelijk virtueel tot stand is gekomen.Voorziene uitkomsten van het onderzoek naar de (virtuele) praktijk zijn:-Een nieuw ontworpen virtuele vorm van persoonsgericht musiceren met kwetsbare ouderen die (nog) thuis wonen en hun mantelzorgers, mogelijk inzetbaar in diverse situaties van isolatie;-Beter begrip van de bijdrage die (virtueel) persoonsgericht musiceren kan leveren aan het welzijn van kwetsbare ouderen, hun mantelzorgers en hun directe omgeving.Professionele musici ontwikkelen steeds vaker praktijken in ouderenzorgcontexten. De afgelopen jaren heeft het lectoraat Lifelong Learning in Music in samenwerking met (inter)nationale partners uit de muziek- en zorgsector nieuwe intramurale persoonsgerichte muziekpraktijken ontwikkeld: in verpleeghuizen voor mensen met dementie (Muziek en Dementie 2010-2014) en in het ziekenhuis (MiMiC - Meaningful Music in Healthcare 2015-heden). Gemeenschappelijk bij al deze praktijken is de persoonsgerichte aanpak, waarbij musici (gearrangeerd) repertoire spelen of een nieuw stuk improviseren, ‘in het moment’ en op maat van mensen. Binnen het huidige muziekaanbod voor ouderen zijn veel praktijken gericht op woonzorg- en verpleeghuizen. Het grootste deel van de kwetsbare ouderen in Nederland woont echter thuis. Dichtbij met muziek wil onderzoeken hoe persoonsgericht musiceren kan worden ingezet op maat van een groeiende groep thuiswonende kwetsbare ouderen en hun mantelzorgers. Als gevolg van de coronapandemie is de ontwikkeling van de praktijk gestart op virtuele wijze.Het doel van dit onderzoek is de ontwikkeling van een virtuele vorm van persoonsgericht musiceren voor kwetsbare ouderen en hun naasten, cq. mantelzorgers, waarbij wordt gedoeld op het versterken van bestaande relaties en gevoel van menselijke waardigheid.
