from the article: "The purpose of this paper is to design a rubric instrument for assessing oral presentation performance in higher education and to test its validity with an expert group. Design/methodology/approach This study, using mixed methods, focusses on: designing a rubric by identifying assessment instruments in previous presentation research and implementing essential design characteristics in a preliminary developed rubric; and testing the validity of the constructed instrument with an expert group of higher educational professionals (n=38). Findings The result of this study is a validated rubric instrument consisting of 11 presentation criteria, their related levels in performance, and a five-point scoring scale. These adopted criteria correspond to the widely accepted main criteria for presentations, in both literature and educational practice, regarding aspects as content of the presentation, structure of the presentation, interaction with the audience and presentation delivery. Practical implications Implications for the use of the rubric instrument in educational practice refer to the extent to which the identified criteria should be adapted to the requirements of presenting in a certain domain and whether the amount and complexity of the information in the rubric, as criteria, levels and scales, can be used in an adequate manner within formative assessment processes. Originality/value This instrument offers the opportunity to formatively assess students’ oral presentation performance, since rubrics explicate criteria and expectations. Furthermore, such an instrument also facilitates feedback and self-assessment processes. Finally, the rubric, resulting from this study, could be used in future quasi-experimental studies to measure students’ development in presentation performance in a pre-and post-test situation."

Purpose The purpose of this paper is to synthesize the fragmented literature on organizational citizenship behavior (OCB), leader–member exchange (LMX), learning, innovative work behavior (IWB) and employee performance across different countries, disciplines and organizations, thereby broadening the literature breath and making gap identification comprehensive. Second, it provides information on how much studies have been concentrated on Africa with the goal of provoking scholarly work in a unique cultural setting on the interrelatedness of these concepts. Design/methodology/approach Relevant literature search was undertaken using key search terms, “employee performance,” “OCB,” “LMX,” “IWB,” “individual learning” and “team learning.” Findings The findings show positive relationships between the behaviors and employee performance. They also reveal an interesting diversity in the study across multidisciplinary fields holding both cultural and contextual significance for academia and practitioners. Research limitations/implications – The limitation of literature to peer-reviewed journals from the authors’ university library might have missed important information not in this domain. Further studies must make use of additional search terms and engines excluded from this study to provide a more comprehensive analysis. Practical implications The paper has important managerial implications for practitioners. The analysis can support the understanding of employee performance from a broader and more diverse view points; and help in providing insight into real-life opportunities, constraints and solutions in enhancing performance management. Originality/value – This systematic literature review highlights important knowledge gaps which need to be explored especially in the African and Ghanaian contexts.
Objective: To determine content validity of the Muscle Power Sprint Test (MPST) and construct validity and reliability of the MPST, 10x5 Meter Sprint Test (10x5MST), slalom test and one stroke push test (1SPT) in wheelchair-using youth with spina bifida (SB). Design: Clinimetric study Setting: Rehabilitation centers, SB outpatient services, private practices Participants: A convenience sample of 53 children (5-19 years, 32 boys / 21 girls) with SB who use a manual wheelchair. Participants were recruited in the Netherlands through rehabilitation centers, SB outpatient services, pediatric physical therapists and the BOSK (Association of and by parents of children, adolescents and adults with a disability). Interventions: Not applicable. Main Outcome Measures: Construct validity of the the MPST was determined by comparing results with the arm-cranking Wingate Anaerobic test (WAnT) using paired t-tests and Pearson Correlation Coefficients, while content validity was assessed using time based criteria for anaerobic testing . Construct validity of the 10x5MST, slalom test and 1SPT was analyzed by hypothesis testing using Pearson Correlation Coefficients and Multiple Regression. For reliability, Intra Class Correlation coefficients (ICC) and smallest detectable changes (SDC) were calculated. Results: For the MPST, mean exercise time of four sprints was 28.1 sec. (±6.6 sec.). Correlations between the MPST and WAnT were high (r>0.72, p<0.01). Excellent correlations were found between the 10x5MST and slalom test (r=0.93, p<0.01), while correlations between the10x5MST or slalom test and MPST and 1SPT were moderate (r=-0.56- -0.70; r=0.56, p<0.01). The 1SPT was explained for 38% by wheelchair mass (Beta -0.489) and total upper muscle strength (Beta 0.420). All ICCs were excellent (ICC>0.95) but the SDCs varied widely. Conclusions: The MPST, 10x5MST and slalom test are valid and reliable tests in wheelchair-using youth with SB for measuring respectively anaerobic performance or agility. For the 1SPT, both validity and reliability are questionable.
The European eel (Anguilla anguilla) is a delicacy fish and an integral part of the Dutch culinary history. However, the stock of adult eel has decreased significantly due to a precipitous recruitment of glass eel fall. This relates to multiple factors including obstacles in migration pathways, loss of habitat and chemical pollution. Consequently, Anguilla anguilla has become a critically endangered species and is protected under European legislation. One possible solution, explored on laboratory scale, is the captive reproduction of eels and growth of glass eel in aquaculture. A big challenge of this technique is the limiting aspect of possible nutrients for the eels in the larval stage, as the diet must be delivered in micrometric capsules (< 20 µm) with a high protein content. Such diets are not yet available on the market. Electrohydrodynamic atomization (EHDA) is a novel option to prepare a micro-diet suitable for eel larvae. EHDA is especially interesting for its narrow size distribution capabilities and for applications which require submicrometric sizes. This project aims to evaluate the use of EHDA to produce high protein content micrometric size capsules for feeding larval eels. If successful, this would assist in the captivity production of glass eel and to make the eel culture independent of wild catches, restoring the culinary market. The project will be conducted in two phases. Firstly, tests will be conducted to evaluate the necessary conditions of the capsules using EHDA. Subsequently, the obtained capsules will be tested as feed for eel larvae. The main objective is to favour the development of a more sustainable eel culture, regarding the possibilities of investigating the current fish in natura option and exchanging it for a captivity one.
Als gevolg van de energietransitie wordt het steeds moeilijker om energieaanbod en -vraag op elkaar af te stemmen en ontstaan problemen op het elektriciteitsnet. Energieopslag biedt een oplossing: duurzame energie wordt opgeslagen op momenten dat er aanbod en weinig energievraag is en beschikbaar gesteld wanneer er weinig aanbod en veel vraag is. Lokale opslag biedt een kans om lokale uitval van het elektriciteitsnet te voorkomen en geeft meerwaarde aan duurzame energie. Opslag in waterstof is uitermate geschikt voor zowel toepassingen op MW-schaal (windparken), voor seizoensopslag en voor toepassingen waar distributie relevant is. De wens van bedrijventerreinen om te verduurzamen biedt een kans om gericht aan oplossingen voor lokale energieopslag in waterstof en bijbehorende toepassingen te werken. In dit project werkt de HAN samen met MKB-bedrijven, Saxion, TU Delft, lokale overheden en een aantal overige partners aan het ontwikkelen en optimaliseren van een energieopslagsysteem gebaseerd op waterstof en bijbehorende waterstoftoepassingen op en voor bedrijventerrein IPKW in Arnhem. Beschikbare windenergie van in aanbouw zijnde turbines langs de Rijn bij IPKW vormen de aanleiding voor het ontwerpen, modelleren, construeren en testen van een (geschaald) energieopslagsysteem gebaseerd op de productie, en opslag van waterstof. Specifieke toepassingen op het industriepark worden geïnventariseerd, en waar mogelijk gerealiseerd en gemonitord, voor met name lokaal bedrijfstransport en elektriciteitslevering. Scenario’s voor ontwikkeling en toepassing van de technologie ontwikkeld en haalbaarheidsstudies uitgevoerd. Kennis en expertise worden ontwikkeld om het proces van optimale implementatie van waterstof voor energieopslag in een energieketen met specifieke toepassingen op een bedrijventerrein te ondersteunen. Met dit project bouwen wij voort op de vele eerdere waterstofprojecten die bij de HAN zijn uitgevoerd en maken we gebruik van ons recent gerealiseerde shared facility HAN Waterstoflab op IPKW.
Het doel van het project is om inzicht te krijgen in praktische en commerciële haalbaarheid rondom de Aquabooster van het bedrijf Wabbi dat eigendom is van studentondernemer Faik Durmus. Het onderzoek waaruit de Aquabooster is ontstaan is gedaan door studenten van de opleiding Biologie en Medisch Laboratoriumonderzoek aan de Saxion Hogeschool. Daarmee borduurt dit project voort op praktijkgericht onderzoek vanuit een kennisinstelling. De Aquabooster is het enige product van het bedrijf Wabbi. De Aquabooster reinigt herbruikbare flessen (zoals de Dopper®) van consumenten met als doel de levensduur te verlengen en de afvalberg te verlagen. Hiermee hoopt Wabbi bij te dragen aan SDG12: ‘Responsible consumption and production’. De belangrijkste projectactiviteiten om het doel te realiseren omvatten: a. Het bouwen van meerdere prototypes; b. Validatie van de prototypes in relevante fieldlabs teneinde feedback uit de markt te krijgen; c. Onderzoek naar Intellectueel Eigendom; d. Schrijven van een businessplan. Deze activiteiten moeten er toe leiden dat er een beeld ontstaat over de potentie van Wabbi met haar Aquabooster. Het project duurt 9 maanden en het budget bedraagt conform begroting €40.000. De projectpartners zijn: Wabbi, Het Saxion Centrum voor Ondernemerschap (penvoerder), de lectoraten Mechatronica en Industrial Design en een partner ten aanzien van het onderzoek naar Intellectueel Eigendom (wordt nog gezocht). Aanvullend worden studenten ingezet om feedback uit de markt te krijgen en deelsystemen te ontwikkelen.
