Big data analytics received much attention in the last decade and is viewed as one of the next most important strategic resources for organizations. Yet, the role of employees' data literacy seems to be neglected in current literature. The aim of this study is twofold: (1) it develops data literacy as an organization competency by identifying its dimensions and measurement, and (2) it examines the relationship between data literacy and governmental performance (internal and external). Using data from a survey of 120 Dutch governmental agencies, the proposed model was tested using PLS-SEM. The results empirically support the suggested theoretical framework and corresponding measurement instrument. The results partially support the relationship of data literacy with performance as a significant effect of data literacy on internal performance. However, counter-intuitively, this significant effect is not found in relation to external performance.

BackgroundPatients undergoing total knee arthroplasty (TKA) often experience strength deficits both pre- and post-operatively. As these deficits may have a direct impact on functional recovery, strength assessment should be performed in this patient population. For these assessments, reliable measurements should be used. This study aimed to determine the inter- and intrarater reliability of hand-held dynamometry (HHD) in measuring isometric knee strength in patients awaiting TKA.MethodsTo determine interrater reliability, 32 patients (81.3% female) were assessed by two examiners. Patients were assessed consecutively by both examiners on the same individual test dates. To determine intrarater reliability, a subgroup (n = 13) was again assessed by the examiners within four weeks of the initial testing procedure. Maximal isometric knee flexor and extensor strength were tested using a modified Citec hand-held dynamometer. Both the affected and unaffected knee were tested. Reliability was assessed using the Intraclass Correlation Coefficient (ICC). In addition, the Standard Error of Measurement (SEM) and the Smallest Detectable Difference (SDD) were used to determine reliability.ResultsIn both the affected and unaffected knee, the inter- and intrarater reliability were good for knee flexors (ICC range 0.76-0.94) and excellent for knee extensors (ICC range 0.92-0.97). However, measurement error was high, displaying SDD ranges between 21.7% and 36.2% for interrater reliability and between 19.0% and 57.5% for intrarater reliability. Overall, measurement error was higher for the knee flexors than for the knee extensors.ConclusionsModified HHD appears to be a reliable strength measure, producing good to excellent ICC values for both inter- and intrarater reliability in a group of TKA patients. High SEM and SDD values, however, indicate high measurement error for individual measures. This study demonstrates that a modified HHD is appropriate to evaluate knee strength changes in TKA patient groups. However, it also demonstrates that modified HHD is not suitable to measure individual strength changes. The use of modified HHD is, therefore, not advised for use in a clinical setting.

Background: A Dutch nationwide prospective cohort study was initiated to investigate recovery trajectories of people recovering from coronavirus disease 2019 (COVID-19) and costs of treatment by primary care allied health professionals. Objectives: The study described recovery trajectories over a period of 12 months and associated baseline characteristics of participants recovering from COVID-19 who visited a primary care allied health professional. It also aimed to provide insight into the associated healthcare and societal costs. Methods: Participants completed participant-reported standardized outcomes on participation, health-related quality of life, fatigue, physical functioning, and costs at baseline (ie, start of the treatment), 3, 6, 9 and 12 months. Results: A total of 1451 participants (64 % women, 76 % mild/moderate severity) with a mean (SD) age of 49 (12) years were included. Linear mixed models showed significant and clinically relevant improvements over time in all outcome measures between baseline and 12 months. Between 6 and 12 months, we found significant but not clinically relevant improvements in most outcome measures. Having a worse baseline score was the only baseline factor that was consistently associated with greater improvement over time on that outcome. Total allied healthcare costs (mean €1921; SEM €48) made up about 3% of total societal costs (mean €64,584; SEM €3149) for the average participant in the cohort. Conclusions: The health status of participants recovering from COVID-19 who visited an allied health professional improved significantly over a 12-month follow-up period, but nearly the improvement occurred between baseline and 6 months. Most participants still reported severe impairments in their daily lives, and generated substantial societal costs. These issues, combined with the fact that baseline characteristics explained little of the variance in recovery over time, underscore the importance of continued attention for the management of people recovering from COVID-19.

Chemical preservation is an important process that prevents foods, personal care products, woods and household products, such as paints and coatings, from undesirable change or decomposition by microbial growth. To date, many different chemical preservatives are commercially available, but they are also associated with health threats and severe negative environmental impact. The demand for novel, safe, and green chemical preservatives is growing, and this process is further accelerated by the European Green Deal. It is expected that by the year of 2050 (or even as soon as 2035), all preservatives that do not meet the ‘safe-by-design’ and ‘biodegradability’ criteria are banned from production and use. To meet these European goals, there is a large need for the development of green, circular, and bio-degradable antimicrobial compounds that can serve as alternatives for the currently available biocidals/ preservatives. Anthocyanins, derived from fruits and flowers, meet these sustainability goals. Furthermore, preliminary research at the Hanze University of Applied Science has confirmed the antimicrobial efficacy of rose and tulip anthocyanin extracts against an array of microbial species. Therefore, these molecules have the potential to serve as novel, sustainable chemical preservatives. In the current project we develop a strategy consisting of fractionation and state-of-the-art characterization methods of individual anthocyanins and subsequent in vitro screening to identify anthocyanin-molecules with potent antimicrobial efficacy for application in paints, coatings and other products. To our knowledge this is the first attempt that combines in-depth chemical characterization of individual anthocyanins in relation to their antimicrobial efficacy. Once developed, this strategy will allow us to single out anthocyanin molecules with antimicrobial properties and give us insight in structure-activity relations of individual anthocyanins. Our approach is the first step towards the development of anthocyanin molecules as novel, circular and biodegradable non-toxic plant-based preservatives.
Ten gevolge van de klimaatverandering Nederland bedreigt. De Verenigde Naties benoemt ‘17 Gobal Goals for a Sustainable Development’ nader gespecificeerd. Goal 13:” versterk de veerkracht en het aanpassingsvermogen aan klimaatgerelateerde gevaren en natuurrampen”. Deze klimaatverandering vraagt om een continue inzicht in de waterafvoercapaciteit van Nederlandse water-infrastructuur. Autonome vaartuigen maken een continue bemeting en realtime informatie van de vaarwegen mogelijk op basis waarvan waar snel actie ondernomen kan worden. Diverse partijen zowel publiek als privaat hebben de wens om continue en autonoom te varen en zijn afzonderlijk hiermee bezig zoals onder andere Rijkswaterstaat, Saeport Groningen en Provincie Overijssel . Het lectoraat mechatronica, dat succesvol onderzoek doet naar ‘autonome systemen in ongestructureerde omgevingen’ heeft veel kennis en ervaring op het gebied van grond (2D navigatie) en lucht robots (3D navigatie). Deze ontwikkelde technologieën zijn potentieel zeer geschikt voor navigatie op het water (2D, 2.5D) en onderwater (3D). Tijdens de vraaginventarisatie bleek er reeds veel interesse van partijen om kennis te delen en samen door te ontwikkelen. Er zijn semi-autonome vaartuigen beschikbaar hiervoor, maar bij de partijen ontbrak een totaal overzicht van de huidige stand van der technologie. Daarom wil het lectoraat Mechatronica samen met Marinminds, Aquatic Drones en DronExpert een onderzoek uitvoeren naar de ‘State of the Art’ betreft autonoom varen. In dit project zal dit onderzoek worden uitgevoerd door specificatie van de gewenste functionele bouwblokken (WP1), een state-of-the art van beschikbare technische oplossingen (WP2), een Gap-analysis tussen deze beide (WP3), verkennende experimenten hiernaar met behulp van een demonstrator (WP4) en een nieuwe specifiek gemaakte projectaanvraag (WP5). Dit cross-over project van de topsector HTSM/SmartIndustry met de topsector Water & Maritiem versterkt al direct de kennispositie van alle betrokken partijen, waardoor deze consortia sneller de vaarwegen klimaat-adaptief kunnen maken, zodat daarmee de Nederlandse (water) veiligheid beter wordt geborgd.
The impacts of tourism on destinations and the perceptions of local communities have been a major concern both for the industry and research in the past decades. However, tourism planning has been mainly focused on traditions that promote the increase of tourism without taking under consideration the wellbeing of both residents and visitors. To develop a more sustainable tourism model, the inclusion of local residents in tourism decision-making is vital. However, this is not always possible due to structural, economic and socio-cultural restrictions that residents face resulting to their disempowerment. This study aims to explore and interpret the formal processes around tourism decision-making and community empowerment in urban settings. The research proposes a comparative study of three urban destinations in Europe (The Hague in the Netherlands, San Sebastian in Spain and, Ioannina in Greece) that experience similar degree of tourism growth. The proposed study will use a design-based approach in order to understand tourism decision-making and what empowers or disempowers community participation within the destinations. Based on the findings of primary and secondary data, a community empowerment model will be applied in one the destinations as a pilot for resident engagement in tourism planning. The evaluation of the pilot will allow for an optimized model to be created with implications for tourism planning at a local level that can contribute to sustainable destinations that safeguard the interests of local residents and tourists.
