PURPOSE: To investigate the reliability and validity of the SQUASH physical activity (PA) questionnaire in a multi-ethnic population living in the Netherlands.METHODS: We included participants from the HELIUS study, a population-based cohort study. In this study we included Dutch (n = 114), Turkish (n = 88), Moroccan (n = 74), South-Asian Surinamese (n = 98) and African Surinamese (n = 91) adults, aged 18-70 years. The SQUASH was self-administered twice to assess test-re-test reliability (mean interval 6-7 weeks) and participants wore an accelerometer and heart rate monitor (Actiheart) to enable assessment of construct validity.RESULTS: We observed low test-re-test reliability; Intra class correlation coefficients ranged from low (0.05 for moderate/high intensity PA in African Surinamese women) to acceptable (0.78 for light intensity PA in Moroccan women). The discrepancy between self-reported and measured PA differed on the basis of the intensity of activity: self-reported light intensity PA was lower than measured but self-reported moderate/high intensity PA was higher than measured, with wide limits of agreement. The discrepancy between questionnaire and Actiheart measures of moderate intensity PA did not differ between ethnic minority and Dutch participants with correction for relevant confounders. Additionally, the SQUASH overestimated the number of participants meeting the Dutch PA norm; Cohen's kappas for the agreement were poor, the highest being 0.30 in Dutch women.CONCLUSION: We found considerable variation in the test-re-test reliability and validity of self-reported PA with no consistency based on ethnic origin. Our findings imply that the SQUASH does not provide a valid basis for comparison of PA between ethnic groups.

Objective: To examine the prevalence of sarcopenia and its association with protein intake in men and women in a multi-ethnic population. Design: We used cross-sectional data from the HELIUS (Healthy Life in an Urban Setting) study, which includes nearly 25,000 participants (aged 18–70 years) of Dutch, South-Asian Surinamese, African Surinamese, Turkish, Moroccan, and Ghanaian ethnic origin. For the current study, we included 5161 individuals aged 55 years and older. Sarcopenia was defined according to the EWGSOP2. In a subsample (N = 1371), protein intake was measured using ethnic-specific Food Frequency Questionnaires. Descriptive analyses were performed to study sarcopenia prevalence across ethnic groups in men and women, and logistic regression analyses were used to study associations between protein intake and sarcopenia. Results: Sarcopenia prevalence was found to be sex- and ethnic-specific, varying from 29.8% in Turkish to 61.3% in South-Asian Surinamese men and ranging from 2.4% in Turkish up to 30.5% in South-Asian Surinamese women. Higher protein intake was associated with a 4% lower odds of sarcopenia in the subsample (OR = 0.96, 95%-CI: 0.92–0.99) and across ethnic groups, being only significant in the South-Asian Surinamese group. Conclusion: Ethnic differences in the prevalence of sarcopenia and its association with protein intake suggest the need to target specific ethnic groups for prevention or treatment of sarcopenia.

Background to the problem Dutch society demonstrates a development which is apparent in many societies in the 21st century; it is becoming ethnically heterogeneous. This means that children who are secondlanguage speakers of Dutch are learning English, a core curriculum subject, through the medium of the Dutch language. Research questions What are the consequences of this for the individual learner and the class situation?Is a bi-lingual background a help or a hindrance when acquiring further language competences. Does the home situation facilitate or impede the learner? Additionally, how should the TEFL professional respond to this situation in terms of methodology, use of the Dutch language, subject matter and assessment? Method of approach A group of ethnic minority students at Fontys University of Professional Education was interviewed. The interviews were subjected to qualitative analysis. To ensure triangulation lecturers involved in teaching English at F.U.P.E. were asked to fill in a questionnaire on their teaching approach to Dutch second language English learners. Thier response was quantitatively and qualitatively analysed. Findings and conclusions The students encountered surprisingly few problems. Their bi-lingualism and home situation were not a constraint in their English language development. TEFL professionals should bear the heterogeneous classroom in mind when developing courses and lesson material. The introduction to English at primary school level and the assessment of DL2 learners require further research.

Titel: The Exodus from the Netherlands or Brain Circulation: Push and Pull Factors of Remigration among Highly Educated Turkish Dutch Auteurs: Gürkan Çelik and Ton Notten In: European Review, 22 (3), 2014, pp. 403-413 The exodus from the Netherlands or brain circulation: Push and pull factors of remigration among highly educated Turkish-Dutch An increasing number of Turks, the Netherlands’ largest ethnic minority, are beginning to return to their country of origin, taking with them the education and skills they have acquired abroad, as the Netherlands faces challenges from economic difficulties, social tension and increasingly powerful right wing parties. At the same time Turkey’s political, social and economic conditions have been improving, making returning home even more appealing for Turkish migrants at large. This article gives explanations about the push and pull factors of return migration. The factors influencing return to one’s country of origin are “pulls”. It is assumed that remigration is more affected by positive developments in the country of origin than by negative developments in the country of residence. Civil society, business world and the Dutch government can develop policies to bind these capable people to the Netherlands, at least in the form of “brain circulation” so that they can serve as “bridge builders” between the two countries. Keywords Return migration, integration, Turkish-Dutch, Turkish migrants, brain circulation =============================================================================== SAMENVATTING De uittocht uit Nederland of breincirculatie: Push- en pull-factoren van remigratie onder hoogopgeleide Turkse Nederlanders. In Nederland zien we een lichte toename van het aantal Turken, de grootste etnische minderheidsgroep in Nederland, die terugkeren naar hun land van herkomst. Ze exporteren daarmee goede opleidingen en vaardigheden die ze in Nederland verwierven. De oorzaken: de economische neergang, sociale spanningen en de groeiende invloed van extreemrechtse partijen. Tegelijkertijd verbeteren in Turkije de politieke, sociale en economische omstandigheden die steeds meer aantrekkingskracht uitoefenen op immigranten in dat land. Dit artikel gaat in op de push- and pull-factoren voor remigranten. Pull-factoren beinvloeden iemands terugkeer naar zijn land van herkomst. Aangenomen wordt dat zo’n remigratie sterker wordt bevorderd door positieve ontwikkelingen in het land van herkomst dan door negatieve (push-factoren) in het land waar men op dat moment woont. De civil society, het bedrijfsleven en de Nederlandse overhead kunnen een beleid ontwikkelen dat verdienstelijke inwoners weet te behouden, hen op z’n minst kan inschakelen als bruggenbouwers en aldus kenniscirculatie mogelijk maakt tussen beide landen. Trefwoorden Retourmigratie, integratie, Turkse Nederlanders, Turkse migranten, kenniscirculatie, breincirculatie

The crossroads of living in cities on the one hand and ageing of the population on the other is studied in an interdisciplinary field of research called urban ageing (van Hoof and Kazak 2018, van Hoof et al. 2018). People live longer and in better health than ever before in Europe. Despite all the positive aspects of population ageing, it poses many challenges. The interaction of population ageing and urbanisation raises issues in various domains of urban living (Phillipson and Buffel 2016). According to the Organisation for Economic Co-operation and Development (OECD 2015), the population share of those of 65 years old is expected to climb to 25.1% in 2050 in its member states. Cities in particular have large numbers of older inhabitants and are home to 43.2% of this older population. The need to develop supportive urban communities are major issues for public policy to understand the relationship between population ageing and urban change (Buffel and Phillipson 2016). Plouffe and Kalache (2010) see older citizens as a precious resource, but in order to tap the full potential these people represent for continued human development (Zaidi et al. 2013), the world’s cities must ensure their inclusion and full access to urban spaces, structures, and services. Therefore, cities are called upon to complement the efforts of national governments to address the consequences of the unprecedented demographic shift (OECD 2015). Additionally, at the city level there is a belief to understand the requirements and preferences of local communities (OECD 2015). An important question in relation to urban ageing is what exactly makes a city age-friendly (Alley et al. 2007, Lui et al. 2009, Plouffe and Kalache 2010, Steels 2015, Moulaert and Garon 2016, Age Platform Europe 2018)? Another relevant question is which factors allow some older people in cities to thrive, while others find it hard to cope with the struggles of daily life? This chapter explores and describes which elements and factors make cities age-friendly, for instance, on the neighbourhood level and in relation to technology for older people.

New approach methodologies predicting human cardiotoxicity are of interest to support or even replace in vivo-based drug safety testing. The present study presents an in vitro–in silico approach to predict the effect of inter-individual and inter-ethnic kinetic variations in the cardiotoxicity of R- and S-methadone in the Caucasian and the Chinese population. In vitro cardiotoxicity data, and metabolic data obtained from two approaches, using either individual human liver microsomes or recombinant cytochrome P450 enzymes (rCYPs), were integrated with physiologically based kinetic (PBK) models and Monte Carlo simulations to predict inter-individual and inter-ethnic variations in methadone-induced cardiotoxicity. Chemical specific adjustment factors were defined and used to derive dose–response curves for the sensitive individuals. Our simulations indicated that Chinese are more sensitive towards methadone-induced cardiotoxicity with Margin of Safety values being generally two-fold lower than those for Caucasians for both methadone enantiomers. Individual PBK models using microsomes and PBK models using rCYPs combined with Monte Carlo simulations predicted similar inter-individual and inter-ethnic variations in methadone-induced cardiotoxicity. The present study illustrates how inter-individual and inter-ethnic variations in cardiotoxicity can be predicted by combining in vitro toxicity and metabolic data, PBK modelling and Monte Carlo simulations. The novel methodology can be used to enhance cardiac safety evaluations and risk assessment of chemicals.

Urban ageing is an emerging domain that deals with the population of older people living in cities. The ageing of society is a positive yet challenging phenomenon, as population ageing and urbanisation are the culmination of successful human development. One could argue whether the city environment is an ideal place for people to grow old and live at an old age compared to rural areas. This viewpoint article explores and describes the challenges that are encountered when making cities age-friendly in Europe. Such challenges include the creation of inclusive neighbourhoods and the implementation of technology for ageing-in-place. Examples from projects in two age-friendly cities in The Netherlands (The Hague) and Poland (Cracow) are shown to illustrate the potential of making cities more tuned to the needs of older people and identify important challenges for the next couple of years. Overall, the global ageing of urban populations calls for more age-friendly approaches to be implemented in our cities. It is a challenge to prepare for these developments in such a way that both current and future generations of older people can benefit from age-friendly strategies.

Current global trends show that different regions of the globe face an increased level of urbanization, and there is a swift aging process from the Western to the Eastern European countries. Romania is a typical country expecting to triple the percentage of the older population aged 65 and over in the next 30 years. Urban policies often neglect such demographic perspectives. The World Health Organization launched the age-friendly city and communities' movement that proposes solutions for older people to age actively by improving their welfare and social participation. The concept of an age-friendly city comprised eight dimensions: (1) outdoor spaces and buildings; (2) transportation; (3) housing; (4) social participation; (5) respect and social inclusion; (6) civic participation and employment; (7) communication and information; and (8) community support and health services. It raises some important questions about how to measure and evaluate urban policies in this framework. Current work presents the process of adaptation and validation for the Romanian older population of a standardized tool - the Age-Friendly Cities and Communities Questionnaire (AFCCQ). The validation study was conducted in Bucharest (n = 424) on a representative sample of older people, who were asked to rate their life in the city, following the eight dimensions and an additional one regarding their financial situation. Four clusters were differentiated in the analysis, resulting in different views of older adults on their experience of living in the city, showing that people's socio-economic status, their living arrangements and health situation play a role in shaping their views on city life. The results highlight the importance of standardized tools to design urban policies following an age-friendly agenda.

The demographics of the homeless population in many countries are currently shifting, and this cannot be explained by the different welfare systems to be found in these countries. Nevertheless, there is some evidence that the homelessness policies of some countries are converging, and we observe a combination of decentralisation, housing first, and a taylor-made, individualised approach. However, what is interesting is the question as to what extent these policies are based on a punitive dimension or on a justice dimension.
