Productie- en handelsdata voor fytosanitair beleid : inventarisatie ten behoeve van risicomanagement

Ter onderbouwing van fytosanitair risicomanagement zijn betrouwbare gegevens noodzakelijk. In dit onderzoek is aangegeven welke gegevens gewenst zijn in relatie tot bepaalde vragen met fytosanitaire achtergrond, waar deze gegevens te vinden zijn en aan welke eisen de gegevens voldoen. In grote lijnen gaat het om drie hoofdthema's: importgegevens vanwege risico's op insleep van organismen; exportgegevens vanwege economische belangen en mogelijke fytosanitaire problemen; gegevens van Nederlandse productie in verband met risico's op verspreiding van organismen en economische belangen. Ten slotte zijn aanbevelingen gedaan om te komen tot een gestructureerde gegevensverzameling in de toekoms

Concurrentiemonitor boomkwekerij

Het rapport Concurrentiemonitor boomkwekerij beschrijft de ontwikkelingen in de Nederlandse boomkwekerijsector en vergelijkt de Nederlandse concurrentiepositie met die van de belangrijkste concurrerende landen: Italië, België, Duitsland en Spanje. Het onderzoek is in grote lijnen uitgevoerd op basis van beschikbaar statistisch bronnenmateriaal. Om enige verdieping aan te kunnen brengen in de analyse heeft een expertbijeenkomst plaatsgevonden met kwekers en handelaren die goed zicht hebben op de concurrentiekracht van de Nederlandse sector

Performance Profile and Carcass Characteristics of Steers Fed Optaflexx

An experiment evaluated the live BW response of steers being fed Optaflexx for various durations. The design consisted of two Optaflexx levels (0 vs. 200 mg per steer daily) and two Optaflexx feeding durations (28 or 42 days immediately prior to slaughter). However, Optaflexx was started on the same day (day 151 of the feeding period). Feeding 200 mg/steer daily of Optaflexx significantly (P\u3c0.01) improved final BW, ADG, and F:G compared to controls. Feeding 200 mg /steer daily of Optaflexx provided 16.4 and 18.8 lb of added BW above controls for the 28 and 42 feeding duration, respectively, but most (approximately 87%) of this weight gain was within the first 28 days of the time that Optaflexx was fed

Practice and the dynamics of handwriting performance: Evidence for a shift of motor programming load

ABSTRACT. Sixteen adult subjects served in an experiment in which the writing of six unfamiliar graphemes was practiced. To investigate the learning process, we analyzed the absolute and relative changes of movement time of the first three consecutive segments as a function of practice. The results showed that movement time of all three segments decreased. This decrease was significantly less in the first segment than it was in the second and third segment, however. We interpret these effects of practice, from an information-processing viewpoint, as follows: (a) Initially separate response segments become integrated in more comprehensive response chunks, and (b) the preparation of later segments of the grapheme is realized more and more during the real-time execution of the initial segment. The results further revealed that these learning effects were more pronounced in graphemes composed of familiar segments than in graphemes that contained unfamiliar segments. Finally, it turned out that similarity between initial and final segments hindered the writing speed of the first segment; the effect of similarity was independent of the above-mentioned effects of practice. The latter effect is interpreted as confirming evidence for the view that the preparation of later segments of a grapheme is reflected by changes of movement time of the first segments of a grapheme

Eczema apps conformance with clinical guidelines: a systematic assessment of functions, tools and content

Background Eczema is a prevalent complex skin condition requiring active disease monitoring and personalized education. No studies have assessed the quality of apps that aim to support eczema self‐management. Objectives To evaluate the quality and comprehensiveness of English, Chinese and Spanish self‐management eczema smartphone apps for patients and/or their caregivers. Methods A systematic assessment of eczema apps from July 2018 to November 2018. The assessment criteria were based on conformance with international eczema guidelines. The following domains were assessed: consistency and comprehensiveness of eczema‐specific educational information; quality and comprehensiveness of eczema‐specific tracking functions; compliance with health information best practice principles. Results In total, 98 apps were assessed: 82 (84%) provided educational information; 38 (39%) tracking functions; and 13 (13%) both. We found that 34% (28/82) of apps provided misleading information, particularly regarding aspects of treatment and disease progression of eczema. Only 15% (12/82) provided international guideline supported information on pharmacological therapies and 16% (13/82) on nonpharmacological therapies. Among 38 apps with a tracking function, 82% (31/38) measured specific symptoms, disease severity or current skin condition and 89% (34/38) helped users to record medication usage including application of topicals. Environmental or dietary allergens were recorded by 34% (13/38). None of the included apps complied with all criteria for educational information, tracking functions or health information principles. Conclusions Eczema apps have not yet reached their potential. The large variance in quality of eczema apps highlights the need for quality assurance mechanisms for health apps and guidance for clinicians that would enable them to make personalized recommendations for patients and caregivers
