    The Adult Attachment Interview (AAI) is a protocol-based, semi-structured interview method widely used to measure adults’ states of mind with respect to attachment. Recently, transcripts of this interview have been used to code secure base script knowledge, which is script-like knowledge related to the way parents dealt with their distress during childhood (ie., child went to parent for comfort, parent provided instrumental and emotional support, child went back to play). Manually coding the verbatim transcripts is labor-intensive and requires a lot of centralized training. The potential integration of machine learning and natural language processing (NLP) techniques may automate certain aspects of AAI analysis, potentially optimizing the process. The aim of this research project is to explore the practical application of these technologies in analyzing AAI transcripts.The project uses data from a pooled set of 12 studies originating from four countries. Upon reviewing the 1,410 AAI transcripts in this set (conducted in three languages), notable discrepancies in the administration of the interviews emerged, some of which may affect the suitability of the interview to assess secure base script knowledge. The first focus of this research project is therefore to develop a model to automatically assess the quality of the transcripts, first for English studies and then for all studies and languages. This model will prioritize evaluating interview characteristics, including instances of unintelligibility and non-adherence to the prescribed AAI protocol. As a next step in the project, employing sentiment analysis will enable an investigation into the correlation between participant-provided adjectives and their corresponding narratives. Finally, this research project will explore the possibility of automatically coding secure base script knowledge in AAI transcripts. By combining technological advances with nuanced human insights, this research project not only provides a pathway toward research studies at scale, but also presents an opportunity to achieve a deeper understanding of emotional and cognitive dimensions within attachment narratives.<br/

    Om aan de eisen van de Kaderrichtlijn Water te voldoen moet in de glastuinbouwsector de emissie van nutriënten en gewasbeschermingsmiddelen sterk worden gereduceerd. Overheid en de glastuinbouwsector zijn in GlaMi-verband overeengekomen, dat in 2027 de emissie nagenoeg nul zal zijn. Spuiwater is een belangrijke emissieroute. In de rozenteelt is groeiremming een belangrijke reden om te spuien. Het zuiveren van het recirculatiewater, bovenop de reeds toegepaste waterontsmetting, zou de groeiproblemen kunnen oplossen en de emissie verminderen. Met een aantal biotoetsen is nagegaan of groeiremming kon worden aangetoond in het drainwater van een aantal rozenbedrijven (fase 0). Vervolgens is getest of zuivering van het water met geavanceerde oxidatie, een combinatie van waterstofperoxide (H2O2) en UV, groeiremming kan terugdringen (fase 1). Behandelingen zijn uitgevoerd met verschillende doseringen H2O2 en UV. Tevens is gekeken naar het effect van deze zuiveringsbehandelingen op de afbraak van gewasbeschermingsmiddelen in het drainwater. De resultaten van de uitgevoerde testen op experimenteel niveau waren veelbelovend. Een kosten/baten analyse is uitgevoerd om zicht te krijgen op de bedrijfeconomische haalbaarheid van de aanschaf van de zuiveringsapparatuur (fase 2). Om het zuiveringconcept met H2O2 en UV in de rozenteelt praktijkrijp te maken is een langdurige proef van een jaar op een praktijkbedrijf essentieel (fase 3). Het gaat om inzicht te krijgen in het effect van geavanceerde oxidatie op de lange termijn op het voorkomen van groeiremming en het minimaliseren van lozing. Een proefplan voor deze duurproef is opgesteld. De vragen, die met deze duurproef moeten worden beantwoord zijn: - Is er groeiremming bij niet-lozen? - Zo ja, vermindert H2O2+UV de groeiremming? - Zo ja, vermindert door H2O2+UV de lozing

    La transferencia de tecnología sostenible es compleja para las firmas de construcción. Una posible solución es analizar esa clase de transferencia como una red social ya que, si se identifican las diferentes relaciones entre los actores del sector construcción, es posible evaluar la capacidad de adaptación tecnológica de dichos actores. El objetivo fue evaluar la transferencia de tecnología sostenible entre empresas constructoras internacionales que se dedican a construir vivienda social o accesible. Para esto, se identificaron dos países con capacidad de transferencia de tecnología sostenible (Reino Unido y Estados Unidos) y dos países de menor capacidad tecnológica y con potencial de adaptarse a dichas tecnologías (Brasil y Colombia); posteriormente, se seleccionaron cinco firmas constructoras por cada país, con las cuales se hizo un análisis de redes (grado, intensidad, cercanía y densidad), y luego, procesos de simulación. Como resultado se identificó la capacidad de transferencia tecnológica que tienen las empresas latinoamericanas para aceptar y adaptar tecnologías de empresas de países industrializados, y se espera poder desarrollar indicadores de medición del proceso de transferencia tecnológica que permitan comprender mejor la complejidad de este proceso en el área de la vivienda social

    Proceedings of On the Move to Meaningful Internet Systems (OTM)Massive-scale distributed computing is a challenge at our doorstep. The current exponential growth of data calls for massive-scale capabilities of storage and processing. This is being acknowledged by several major Internet players embracing the cloud computing model and offering first generation distributed tuple stores. Having all started from similar requirements, these systems ended up providing a similar service: A simple tuple store interface, that allows applications to insert, query, and remove individual elements. Further- more, while availability is commonly assumed to be sustained by the massive scale itself, data consistency and freshness is usually severely hindered. By doing so, these services focus on a specific narrow trade-off between consistency, availability, performance, scale, and migration cost, that is much less attractive to common business needs. In this paper we introduce DataDroplets, a novel tuple store that shifts the current trade-off towards the needs of common business users, pro- viding additional consistency guarantees and higher level data process- ing primitives smoothing the migration path for existing applications. We present a detailed comparison between DataDroplets and existing systems regarding their data model, architecture and trade-offs. Prelim- inary results of the system's performance under a realistic workload are also presented

    Advanced oxidation to eliminate growth inhibition and to degrade plant protection products in a recirculating nutrient solution in Rose cultivation

    The EU Water Framework Directive demands a sound ecological and chemical basis for ground and surface waters. This has motivated the Dutch greenhouse industry to seek more sustainable water management procedures which will enable a zero-emission of nutrients and plant protection products (PPP) in the year 2027. Although closed soilless growing systems are widely applied in The Netherlands, it appears that discharge of nutrients varies between 5 and 40%. Discharge based on salinity is only a minor part, up to 15%. In rose cultivation, growth inhibition is the major reason for discharge of the nutrient solution. Former research could not find a proper reason for growth inhibition, but it is most likely of organic origin. The water treatment method of advanced oxidation, at which first hydrogen peroxide is added, directly followed by an exposure to UV-C light (200-280 nm), is known to degrade large organic molecules. Therefore this method has been investigated to eliminate growth inhibition and also to degrade PPPs. Among all methods advanced oxidation has been a first choice because many rose growers already possess a UV installation for elimination of pathogens from the recirculating solution. Trials with advanced oxidation have been performed at two rose nurseries at which the dosages of hydrogen peroxide (0-25 mg/L) and UV lighting (0-900 mJ/cm2) have been varied to search for indications for elimination of growth inhibition and the degradation of PPPs. After treatment samples were taken to test for growth inhibition of the solution in a bioassay, Phytotoxkit; the chemical composition; the residual amount of PPPs and the presence of micro-organisms. Preliminary results show that (1) growth inhibition exists and can be decreased, (2) plant protection products can be degraded, (3) pathogens have been eliminated and (4) composition of the nutrient solution is unchanged except for iron

    Short-term prognosis of breakthrough venous thromboembolism in anticoagulated patients

    Background: Evidence for guideline recommendations for the treatment of venous thromboembolism (VTE) during anticoagulant therapy is scarce. We aimed to observe and to describe the management of VTE occurring during anticoagulant therapy. Methods: This prospective multi-center, observational study included patients with objectively confirmed VTE during anticoagulant therapy (breakthrough event), with a follow-up of 3 months, after the breakthrough event. Results: We registered 121 patients with a breakthrough event, with a mean age of 56 years (range, 19 to 90); 61 were male (50%). Fifty-eight patients (48%) had an active malignancy. At the time of the breakthrough event, 57 patients (47%) were treated with a vitamin K antagonist (VKA), 53 patients (44%) with low-molecular-weight heparin (LMWH) and 11 patients (9%) with direct oral anticoagulants, unfractionated heparin, or VKA plu

    Objective: Children with suprasellar brain damage are at risk of hypothalamic dysfunction (HD). HD may lead to decreased resting energy expenditure (REE). Decreased REE, however, is not present in all children with HD. Our aim was to assess which children suspect for HD have low REE, and its association with clinical severity of HD or radiological hypothalamic damage.Patients and methods: A retrospective cohort study was performed. Measured REE (mREE) of children at risk of HD was compared to predicted REE (pREE). Low REE was defined as mREE <90% of predicted. The mREE/pREE quotient was associated to a clinical score for HD symptoms and to radiological hypothalamic damage.Results: In total, 67 children at risk of HD (96% brain tumor diagnosis) with a mean BMI SDS of +2.3 +/- 1.0 were included. Of these, 45 (67.2%) had low mREE. Children with severe HD had a significant lower mean mREE/pREE quotient compared to children with no, mild, or moderate HD. Mean mREE/pREE quotient of children with posterior hypothalamic damage was significantly lower compared to children with no or anterior damage. Tumor progression or tumor recurrence, severe clinical HD, and panhypopituitarism with diabetes insipidus (DI) were significant risk factors for reduced REE.Conclusion: REE may be lowered in children with hypothalamic damage and is associated to the degree of clinical HD. REE is, however, not lowered in all children suspect for HD. For children with mild or moderate clinical HD symptoms, REE measurements may be useful to distinguish between those who may benefit from obesity treatment that increases REE from those who would be better helped using other obesity interventions.Analysis and Stochastic
