For my PhD research I build a structural model to predict student success. Initially to show the influence of social media use by first year students in higher education. However, for this research I use the model to investigate the predictive value of a student choice test. This test is mandatory for all students prior to their enrolment at the Amsterdam University of Applied Sciences. In this study two of the Institutes (Communication and Creative Business/Media, Information and Communication) of the Faculty of Digital Media and the Creative Industries participated with a first year enrollment in the year 2017 of 1010 students (respectively of 327 and 683), and in 2018, 1193 students (respectively 225 and 968). This study choice test involved an assignment that the student-to-be had to do at home and bring to the Institute when they took part in the second half of the study choice test. This second half involved an exam in topics central to the curriculum, a Dutch language test and all students had a final meeting with a teacher where they were given a positive or negative advice. Because of the large number of students, a substantial number of teachers and resources were used for this test. In order to see the pros and cons of the test, the predictive value was tested along with other variables which are proven to have a predictive value on student success. The best proven variables from Tinto’s theory were included, based on previous studies. The central variable in Tinto’s study is ‘satisfaction’ (which in other research is revert to as ‘engagement’ of ‘belonging’), consisting originally of a vast number of manifest variables. By using a fraction of those variables, I simplified the model, so it was an easier tool to use for teachers and management and in the meantime, avoiding the capitalization of chance. The smaller latent variable ‘satisfaction’ was tested using principal component analysis to prove the manifest variables where in fact representing one latent variable. Cronbach’s alpha and Guttman’s lambda-2 then provided the internal consistency and reliability of the variable. Along with ‘satisfaction’, the model included different background variables (gender, prior education, ethnicity), commitment and effort, expected progress and of course study success. This was measured by the time it takes a student to finish all first year exams and the average grade point (GPA). SPSS AMOS was used for testing the fit of the model and showed reasonable values for the normed fit index (NFI), the comparative fit index (CFI), the Tucker-Lewis Index (TLI) and the root mean square error of approximation (RMSEA). The advice from the study choice test and the scores were tested in the model to uncover if there was a significant difference. Furthermore, the influence of all variables in the model were compared for their influence on study success.

Social work in the Netherlands is attracting an increasing number of Turkish and Moroccan Dutch professionals, mostly second-generation migrant women from a Muslim background. Inspired by Amartya Sen’s capability approach, this article presents the findings of a qualitative content analysis of 40 interviews with professionals by peers from the same background. The question is, what kind of professionals do these newly started social workers desire to be and what hindrances do they encounter? The professionals challenge the dominance of Western beliefs and values. This becomes tangible in their desires and constraints and especially in the process of choice.

Although science, technology, engineering and mathematics (STEM) study paths and STEM work fields may be relatively difficult and therefore not appropriate for everyone, too many children prematurely exclude STEM-related study and work options, based on negative images of the field or negative ability beliefs. In the present article, we provide an overview of the literature from different research perspectives that shows that study choice and career decisions made by young adults have their roots in earlier in childhood. In our view, the literature reviewed points to three interrelated factors that are important in the study choice and career development of children aged 8–16: knowledge, affective value, and ability beliefs and self-efficacy building. Based on this review, we argue that knowledge of the STEM field, and of the self in STEM activities, and parents’ and teachers’ knowledge of the early circumscription processes of children aged 8–16 needs to be broadened. Also, negative and often-stereotypical affective values adhered to STEM study choices or careers among parents and teachers need to be countered. With regard to ability beliefs, we argue that we should focus more attention on turning pupils’ entity beliefs into incremental ones.

The objective of Waterrecreatie Nederland is to improve water recreation in the Netherlands. One of the focus points that the foundation focuses on is strengthening sustainable water recreation. With this study, Waterrecreatie Nederland wants to map the current CO2 emissions of recreational shipping (here: sailing and motor boats), in order to be able to report and communicate about this, and also as a baseline measurement for future monitoring in this area.Societal IssueShipping has a substantial impact on several environmental systems, amongst others through air and water pollution, and its contribution to climate change. The role of recreational shipping in these issues is not well known, as measurements are scarce and often partly based on assumptions. Benifit to societyThis project tries to strengthen the knowledge base on the carbon (CO2) emissions of recreational shipping in the Netherlands, and to provide detail on fuel use, fuel types, distances, etc. That knowledge can help in making more informed choices on the future development of recreational shipping, with a lower impact on climate change.
The production, use, disposal and recovery of packaging not only generates massive volumes of waste, it also consumes raw materials, water and energy (Fitzpatrick et al. 2012). Simultaneously, consumers have shown an increasing interest in products incorporating sustainable and social attributes (Kletzan et al., 2006). As a result, environmentally friendly packaging, also called ecofriendly or sustainable packaging, has become mainstream. In this context, packaging is more than just ensuring the product's protection and easing transportation, it is also a communicative tool (Palmer, 2000) and it becomes associated with multiple drivers of the purchasing process. Consequently, companies face pressure to innovate responding to consumer demands, and focusing on sustainable solutions that reduce harmful materials and favour green alternatives for both, the product and the packaging. Although the above has triggered research on consumer choice for sustainable products and alternatives on sustainable packaging, the relation between sustainable packaging and consumer behaviour remains underexplored. This research unpacks this relationship, i.e., empirically verifies which dimensions (recyclability, biodegradability, reusability) of sustainable packaging are perceived and valued by consumers. Put differently, this research investigates consumer behaviour towards the functions of sustainable packaging in terms of product protection, convenience, reliability of information and promotion, and scrutinises the perceived credibility of the associated ethical responsibility claims. It aims to identify those packaging materials and/or sustainability characteristics perceived as more sustainable by consumers as well as the factors influencing actual consumer choice towards sustainable packaged products. We aim to gain more insights in the perceptual frame that different types of consumers apply when exposed to sustainable packaging. To this end, we will make use of revealed preference methods to measure consumer valuations of sustainable packaged products. This game-theoretic approach should provide a more complete depiction of consumers' perceptions and preferences.
On a yearly basis 120 million kg of spent coffee ground (SCG) is disposed as waste. Two partners in the project have the intension to refine the valuable compounds from this coffee residue. One of these compounds is the group of melanoidins. It is proven that these natural polymers, with polyphenols incorporated, can be used as a colorant for wool. The polyphenols show antioxidant ability and high levels of ultraviolet radiation blocking which will give extra benefits when the SCG extract is applied as a colorant in smart packaging. In this project the extraction process is refined and industrial dyeing methods for wool, cotton and paper are evaluated. SCG colored samples are tested for color intensity and light and wash fastness. For the best coloring results commercial potential will be evaluated in a market study. Prospects in textile, paper and packaging industries are contacted to share their view about the possible applications of SCG extracts as colorants. The results are used in the business plan of the SCG refinery plant. With the SCG extract as a professional biobased colorant in the market, companies in textile, paper and packaging industry will have a wider choice in using environmental friendly products. At the end, this will lead to complete biodegradable products for consumers.
