Monitoring van ziekten en plagen van tomaat, roos en potplanten

Referaat Sensortechnologie neemt een grote vlucht. Beeld verwerkende technieken en technieken voor de detectie van vluchtige stoffen zijn steeds beter in staat om de kleinste details waar te nemen met een steeds hogere snelheid, nauwkeurigheid, intelligentie en datacapaciteit tegen steeds lagere kosten. Het idee is om de nieuwe sensortechnologie toe te passen op basis van bestaande infrastructuur om ziekten en plagen te signaleren en te interpreteren, om vervolgens over te gaan tot de juiste maatregelen en acties. In een beperkte consultancy opdracht is parate kennis van onderzoekers, probleemhouders en andere experts verzameld, met een afsluitende workshops is aan aanpak voor vervolg gepresenteerd. Een uitgebreide literatuurstudie en expert review heeft niet plaatsgevonden. In de afsluitende workshop hebben probleemhouders in roos en potplanten zich positief uitgelaten voor verdere implementati

Exploring the Application of NLP in Narrative Patterns of Adult Attachment

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/

The eye lens dose of the interventionalist:Measurement in practice

Objective: Early 2018, the new eye lens dose limit of 20 mSv per year for occupational exposure to ionising radiation was implemented in the European Union. Dutch guidelines state that monitoring is compulsory above an expected eye lens dose of 15 mSv/year. In this study we propose a method to investigate whether the eye lens dose of interventionalists would exceed 15 mSv/year and to determine if the eye lens dose can be derived from the regular personal dosimeter measurements. Methods: The eye lens dose, Hp(3), of interventional radiologists (n = 2), cardiologists (n = 2) and vascular surgeons (n = 3) in the Máxima Medical Centre, The Netherlands, was measured during six months, using thermoluminescence dosimeters on the forehead. Simultaneously, the surface dose, Hp(0,07), and whole body dose, Hp(10), were measured using regular dosimeters outside the lead skirt at chest level. The dosimeters were simultaneously refreshed every four weeks. The eye lens dose was compared to both the body-worn dosimeter values. Measurements were performed in the angiography suite, Cath lab and hybrid OR. Results: A clear relation was observed between the two dosimeters: Hp(3) ≈ 0,25 Hp(0,07). The extrapolated year dose for the eye lens did not exceed 15 mSv for any of the interventionalists (average 3 to 10 studies/month). Conclusions: The eye lens dose can be monitored indirectly through the regular dosimeter at chest level. Additionally, based on the measurements we conclude that all monitored interventionalists remain below the dose limit and compulsory monitoring limit for the eye lens dose.</p

Chronic sleep reduction in adolescents - clinical cut-off scores for the Chronic Sleep Reduction Questionnaire (CSRQ)

The Chronic Sleep Reduction Questionnaire is a validated questionnaire that measures symptoms of prolonged insufficient and/or poor sleep and therefore accounts for individuals’ sleep need and sleep debt. This study extends its psychometric properties by providing cut-off scores, using a matched sample of 298 healthy adolescents (15.38 ± 1.63 years, 37.9% male, mean Chronic Sleep Reduction Questionnaire score: 32.98 ± 6.51) and 298 adolescents with insomnia/delayed sleep–wake phase disorder (15.48 ± 1.62 years; 37.9% male, mean Chronic Sleep Reduction Questionnaire score: 42.59 ± 7.06). We found an area under the curve of 0.84 (95% confidence interval: 0.81–0.87). Cut-off scores for optimal sensitivity, optimal specificity and based on Youden's criterion are provided. These cut-off scores are highly relevant for use of the Chronic Sleep Reduction Questionnaire in future studies and clinical practice

The rhythm of life: the perfect rhythm of morse code

Morse code is a unique exemplar of the inherent complexities of rhythm. Learning Morse code in wartime presented challenges to expedite skill acquisition. This thesis explored the strategies used to teach and learn Morse code in the second World War and investigated the resourceful techniques used by the WRANS in an empirical study. The first study investigated the teaching and learning strategies of wartime telegraphists to learn Morse code. Five WRANS described a series of techniques to learn Morse code, including rote learning and repetition, visualisation and pattern recognition, intoning and mnemonics, and music. Music provided effective training for the fundamental teaching and learning of Morse code by matching the rhythmical properties of Morse code to music. Music equipped Morse code operators with a unique approach to Morse code instruction. Learning Morse code with music was described as a way of making sense of the ‘rhythm’ and ‘shape’ of the Morse code letters and proved an invaluable aid to learning and teaching Morse code. The second study examined the effectiveness of learning Morse code with the aid of music. Novices formed two groups, Control Group (no music aid) and Music Group (with music aid). Results confirmed the effectiveness of music training in three Morse code letters, Q V, and A in two experiments, the first with known Morse code letters (Q V A) and the second with unknown letters. The Music Group accurately identified 90% of known and unknown Morse code letters compared to the Control Group who identified less then 50% of known and unknown Morse code letters. This thesis explored the transferable attributes of rhythm perception in music as a teaching and learning mechanism for Morse code. There is extensive research on the complex learning and retention of Morse code but the studies in this thesis have indicated that the ground-breaking wartime strategy of music and Morse code is a powerful duo. The investigation of learning and teaching strategies of the WRANS showed that musical rhythm influenced the skill acquisition of Morse code and the perceptual test suggests that current work in rhythm perception extends beyond music pedagogy and has further implications for all cognitive function
