Over the past few decades, education systems, especially in higher education, have been redefined. Such reforms inevitably require reconsideration of operational notions and definitions of quality, along with a number of related concepts. This reconsideration aligns with the core of higher education reforms: improving efficacy and compatibility with emerging social demands while adapting to competitiveness and accountability trends. As primary players in the teaching and learning process, online tutors have a protagonistic role and, therefore, must be equipped with a suitable set of competencies and attributes in addition to content knowledge. This quantitative research aims to analyze the perceptions of 250 online tutors working in European higher education institutions, distributed in 5 knowledge areas: Business, Education, Humanities, Sciences and Health. This descriptive and exploratory nonexperimental study reveals the technological and pedagogical skills and competencies that online tutors consider fundamental for effective online teaching and proposes professional development actions to ensure quality online teaching.

In a recent official statement, Google highlighted the negative effects of fake reviews on review websites and specifically requested companies not to buy and users not to accept payments to provide fake reviews (Google, 2019). Also, governmental authorities started acting against organisations that show to have a high number of fake reviews on their apps (DigitalTrends, 2018; Gov UK, 2020; ACM, 2017). However, while the phenomenon of fake reviews is well-known in industries as online journalism and business and travel portals, it remains a difficult challenge in software engineering (Martens & Maalej, 2019). Fake reviews threaten the reputation of an organisation and lead to a disvalued source to determine the public opinion about brands. Negative fake reviews can lead to confusion for customers and a loss of sales. Positive fake reviews might also lead to wrong insights about real users’ needs and requirements. Although fake reviews have been studied for a while now, there are only a limited number of spam detection models available for companies to protect their corporate reputation. Especially in times with the coronavirus, organisations need to put extra focus on online presence and limit the amount of negative input that affects their competitive position which can even lead to business loss. Given state-of-the-art derived features that can be engineered from review texts, a spam detector based on supervised machine learning is derived in an experiment that performs quite well on the well-known Amazon Mechanical Turk dataset.

This research demonstrates the power and robustness of the vocabulary method by Hernández-Rubio et al. (2019) for aspect extraction from online review data. We showcase that this algorithm not only works on the English language based on the CoreNLP toolkit, but also extend it on the Dutch language, specifically with aid of the Frog toolkit. Results on sampled datasets for three different retailers show that it can be used to extract fine-grained aspects that are relevant to acquire corporate reputation insights.

Tango is among the most widespread world music genres nowadays. However, only partial information about the elements and techniques of composing, arranging and performing tango has been documented and made available so far. This research project aims at investigating tango’s main aspects in the oeuvre of relevant tango musicians, promoting its creative practice and expanding its artistic community. By making the implicit knowledge in scores and recordings explicit and ready for creative use by the greater artistic community, tango can be preserved, on one side; and musicians can experiment and reach new artistic horizons, securing its continuation and development as vivid, contemporary music, on the other. The project has two research questions: 1. What are the main features and techniques of tango music composition, arrangement and performance? 2. How can musicians nowadays integrate these features and techniques into their practice to deepen their understanding and enhance their artistic creations and performances? This research uses a mixed method design, including the analysis of scores and recordings, literature review, interviews, observational studies and experimentation. It expands the artistic community on the topic and bridges two top-notch institutions devoted to tango learning: Codarts and UNSAM (Argentina). The research also endeavours improvements in the Codarts curriculum as it complements and expands its educational programme by providing students with research tools to enhance their creative practice. Theoretical and artistic outcomes will be documented and disseminated in concerts, concert-lectures, papers, articles and a tailor-made website containing compositions, arrangements, videos, text, musical examples and annotated scores, so as to record: a) the musical materials and techniques found in the analysed scores and recordings, together with their applications in practice and performance; b) the artistic processes, reflections and production of the participants; c) information on how to create, arrange and perform tangos.
Aanleiding Mede door de vergrijzing groeit de zorgvraag in Nederland. Tegelijkertijd vallen veel verpleegkundigen uit door fysieke en mentale arbeidsbelasting. Dit begint al tijdens de opleiding/aan de start van de loopbaan. Dreigende arbeidstekorten en decentralisatie in de zorg vragen om verpleegkundigen die regie kunnen voeren over hun eigen werkgerelateerde gezondheid. Er is nog weinig wetenschappelijke kennis over het vroegtijdig signaleren en aanpakken van uitval onder verpleegkundigen. Bovendien hapert de invoer van effectieve interventies. Daarom willen zorginstellingen, verpleegkunde-opleidingen en wetenschappelijke organisaties onderzoek doen naar de oorzaken van uitval en een instrument ontwikkelen om problemen vroegtijdig te herkennen en te ondervangen. Doelstelling Het consortium wil een wetenschappelijk en praktisch onderbouwd instrumentarium ontwikkelen voor het signaleren van risicofactoren, gezondheidsproblemen, productiviteitsverlies en uitval bij stagiairs en beginnende verpleegkundigen, met daaraan gekoppeld effectieve preventieve interventies voor in de onderwijs- en stagepraktijk. Het programma kent twee fases. 1) literatuuronderzoek, kwalitatief onderzoek naar nog onbekende risicofactoren en longitudinaal cohortonderzoek vormen de basis voor een signaleringsinstrument/predictiemodel. In het cohortonderzoek worden van 750 (aankomend) verpleegkundigen 2,5 jaar de determinanten voor uitval gemonitord. In expertmeetings selecteert men vervolgens 6 evidencebased interventies. 2) het onderzoeksteam pre-test deze interventies op eerste haalbaarheid bij studenten verpleegkunde met risico. De 2 kansrijkste interventies, één voor mentale en één voor fysieke werkbelasting, worden in pilots op effectiviteit getoetst. In het onderzoek zet men de psychometrisch beproefde meetinstrumenten in van de European Nurses Early Exit Study (online enquêtes), aangevuld met inzichten uit interviews, fysieke metingen en praktijkobservaties. Beoogde resultaten De beoogde resultaten van het project zijn: " inzicht in de fysieke en mentale problemen van verpleegkundigen; " een gevalideerd predictiemodel voor geïndiceerde preventie in de zorg; " good practices en een kant-en-klare webapplicatie voor vroegsignalering met interventies in het stageonderwijs en het werkveld om uitval te voorkomen; " valorisatie van kennis in co-creatie met studenten, zorginstellingen en zorgprofessionals in de regio; " kennisinput voor de opleidingen Nurse practitioner, Verpleegkunde, Arbeid en Gezondheid, HRM. Een grote groep studenten is respondent in het onderzoek. In de uitvoering participeren ook studenten en daarnaast onder meer lectoren, onderzoekers en docenten van Hogeschool Rotterdam en twee promovendi. Voor de wetenschappelijke disseminatie worden refereerbijeenkomsten en presentaties gehouden op internationale congressen, en proefschriften en artikelen geschreven gepubliceerd. De verspreiding onder maatschappelijke partners gebeurt via vakpublicaties, expertmeetings en een slotsymposium. Met internationale partners uit het netwerk worden mogelijkheden verkend voor internationale parallelstudies.
