Aan de hand van Helen's Free Food Market als voorbeeld beschrijven we in dit artikel informele voedselinitiatieven, die tijdens de coronacrisis in aantal en belang groeiden, als een vorm van 'sociaal schaduwwerk'. Dat verwijst naar informele spelers in het sociaal domein die vormen van welzijn en lichte ondersteuning bieden, die overeenkomen met het formele sociaal werk. Doordat deze spelers niet direct geassocieerd worden met hulpverlening zijn zij laagdrempelig en worden zij soms makkelijker vertrouwd door burgers, die om verschilllende redenen afstand ervaren tot formele voorzieningen.

Background & aims: In dietary practice, it is common to estimate protein requirements on actual bodyweight, but corrected bodyweight (in cases with BMI <20 kg/m2 and BMI ≥30 kg/m2) and fat free mass (FFM) are also used. Large differences on individual level are noticed in protein requirements using these different approaches. To continue this discussion, the answer is sought in a large population to the following question: Will choosing actual bodyweight, corrected bodyweight or FFM to calculate protein requirements result in clinically relevant differences? Methods: This retrospective database study, used data from healthy persons ≥55 years of age and in- and outpatients ≥18 years of age. FFM was measured by air displacement plethysmography technology or bioelectrical impedance analysis. Protein requirements were calculated as 1) 1.2 g (g) per kilogram (kg) actual bodyweight or 2) corrected bodyweight or 3) 1.5 g per kg FFM. To compare these three approaches, the approach in which protein requirement is based on FFM, was used as reference method. Bland–Altman plots with limits of agreement were used to determine differences, analyses were performed for both populations separately and stratified by BMI category and gender. Results: In total 2291 subjects were included. In the population with relatively healthy persons (n = 506, ≥55 years of age) mean weight is 86.5 ± 18.2 kg, FFM is 51 ± 12 kg and in the population with adult in- and outpatients (n = 1785, ≥18 years of age) mean weight is 72.5 ± 18.4 kg, FFM is 51 ± 11 kg. Clinically relevant differences were found in protein requirement between actual bodyweight and FFM in most of the participants with overweight, obesity or severe obesity (78–100%). Using corrected bodyweight, an overestimation in 48–92% of the participants with underweight, healthy weight and overweight is found. Only in the Amsterdam UMC population, protein requirement is underestimated when using the approach of corrected bodyweight in participants with severe obesity. Conclusion: The three approaches in estimation of protein requirement show large differences. In the majority of the population protein requirement based on FFM is lower compared to actual or corrected bodyweight. Correction of bodyweight reduces the differences, but remain unacceptably large. It is yet unknown which method is the best for estimation of protein requirement. Since differences vary by gender due to differences in body composition, it seems more accurate to estimate protein requirement based on FFM. Therefore, we would like to advocate for more frequent measurement of FFM to determine protein requirements, especially when a deviating body composition is to be expected, for instance in elderly and persons with overweight, obesity or severe obesity.

Free newspapers may offer different news contents to different audiences, when compared with traditional, paid-for newspapers, but they, nevertheless, concentrate on news, and thereby provide society with information on current affairs. These papers have seen circulation rise until 2008; after that, a decline set in, leading to closures and often a monopoly situation in the mature European newspaper markets covered in our research. Free newspapers seem to follow a typical life cycle pattern, moving from growth to maturity, and to saturation and decline. Diversification strategies – home-delivery, weekend, sports, afternoon, and financial – have been disappointing so far. There is no evidence, however, of total extinction, indicating that there is room for at least one title – possibly two – in every market. The situation in the surveyed markets also suggests that a free newspaper may be a ‘natural’ monopoly.

Whereas most continents see circulation of newspapers drop, Latin America is one of the few areas in the world with rising newspaper circulation. A substantial part of this rise is caused by the introduction of free newspapers in a dozen countries on the continent. We map this development, discuss possible reasons for the rapid growth and try to answer whether this introduction has substitution effects on paid newspapers. The growth of this new format is most probably caused by economic growth while we conclude that substitution is low, meaning that free dailies serve a new reading audience in Latin America

OBJECTIVE: To examine how a healthy lifestyle is related to life expectancy that is free from major chronic diseases.DESIGN: Prospective cohort study.SETTING AND PARTICIPANTS: The Nurses' Health Study (1980-2014; n=73 196) and the Health Professionals Follow-Up Study (1986-2014; n=38 366).MAIN EXPOSURES: Five low risk lifestyle factors: never smoking, body mass index 18.5-24.9, moderate to vigorous physical activity (≥30 minutes/day), moderate alcohol intake (women: 5-15 g/day; men 5-30 g/day), and a higher diet quality score (upper 40%).MAIN OUTCOME: Life expectancy free of diabetes, cardiovascular diseases, and cancer.RESULTS: The life expectancy free of diabetes, cardiovascular diseases, and cancer at age 50 was 23.7 years (95% confidence interval 22.6 to 24.7) for women who adopted no low risk lifestyle factors, in contrast to 34.4 years (33.1 to 35.5) for women who adopted four or five low risk factors. At age 50, the life expectancy free of any of these chronic diseases was 23.5 (22.3 to 24.7) years among men who adopted no low risk lifestyle factors and 31.1 (29.5 to 32.5) years in men who adopted four or five low risk lifestyle factors. For current male smokers who smoked heavily (≥15 cigarettes/day) or obese men and women (body mass index ≥30), their disease-free life expectancies accounted for the lowest proportion (≤75%) of total life expectancy at age 50.CONCLUSION: Adherence to a healthy lifestyle at mid-life is associated with a longer life expectancy free of major chronic diseases.

Paper presented at Diversity of Journalisms. ECREA Journalism Studies Section and 26th International Conference of Communication (CICOM) The launch of more than 300 free daily newspapers worldwide during the last 15 years defies the idea that newspaper markets are impossible to penetrate. Although a third of papers closed down in the last ten years, newspaper circulation in most countries with free newspapers is actually higher than before their entry. Readership analysis of free newspapers shows that these papers have a younger audience than paid newspapers, contradicting the notion that young people don’t read newspapers anymore.

The EU is confident it will reach its target of 20% renewable energy by 2020. But according to Martien Visser, professor at the Hanze University of Applied Sciences in Groningen (The Netherlands), this 20% is in reality more like 14%. This is because a large part of our energy consumption is simply ignored in the calculations for renewable energy. “Even with 100% renewables, we would still need a lot of fossil fuels”, Visser notes.

Native (flat) oyster (Ostrea edulis) beds, once a major component of the North Sea, largely disappeared from the region in the late 19th century. Flat oyster restoration is taking place at a number of locations in the North Sea. When flat oyster beds are restored in areas where O. edulis is functionally extinct it is advised to treat these as disease-free areas. Adult oysters were collected in the Dutch Delta area which is infected with the pathogenic parasite Bonamia ostreae. The aim of this research was to obtain Bonamia-free seed from parents collected in a Bonamia-infected area. In addition, the oysters were analysed to identify candidate genomic regions related to bonamiosis tolerance and exposed to Bonamia in the field to assess survival compared to a naïve control group. With the aid of a non-destructive screening method, Bonamia-free broodstock were selected. These oysters produced Bonamia-free larvae and seed. For comparison, broodstock oysters were collected in the Dutch Wadden Sea, an area free of Bonamia. These oysters also produced Bonamia-free larvae and seed. To study if the Delta area oysters had developed a degree of resistance to the disease, while the naïve Wadden Sea oysters had not, seed of both groups was challenged in Lake Grevelingen where Bonamia occurs. Survival of the pre-selected Bonamia-free oysters was significantly higher than the naïve group. Samples of seed were analysed for association of candidate genetic markers related to bonamiosis tolerance. A higher percentage of individuals with tolerance-associated marker genotypes was found in the screened group compared to the naïve one. However, mortality of the naïve group could not be related to Bonamia presence. Further challenge tests are needed before firm conclusions regarding the genetic markers can be made. The results show that hatchery production of Bonamia-free and potentially Bonamia-tolerant flat oysters is possible.

In 1999 werden de gratis kranten Metro en Spits in Nederland gelanceerd. Behalve die twee titels werden ook zes andere gratis dagbladen in Nederland gestart tussen 2000 en 2008. In 2007 bereikte de totale gratis oplage een hoogtepunt van bijna twee miljoen per dag. In dit artikel wordt de geschiedenis van de deze categorie kranten beschreven tegen de Europese achtergrond waar ook sprake is van een ‘levenscyclus’ met een snelle opkomst en een sterke sanering die tijdens de economische recessie inzette. Daarnaast wordt ingegaan op de voorlopers van deze mediasoort, op de lezers van gratis kranten en de gevolgen die gratis kranten op de totale krantenoplage in Nederland heeft gehad. Halfway the first decennium of the 21st century free newspapers in the Netherlands had a circulation of almost two million and were responsible for a third of the total newspaper circulation. Four national titles competed. They saw a quick rise and also a sudden decline after 2008. In 2015 only one national model remains. In this article we analyse this development against the European background as several countries in Europe show the same picture. Also the historical context of the global rise of free newspapers – going back to the late 19th century – and kickstarted in 1995 by Metro Sweden -is provided. As free newspapers rely only on advertising for income, a combination of economic recessions and fierce competition can be lethal. Free newspapers mainly compete among themselves which explained the sudden decline in the number of titles and circulation after 2008. Also the rise of digital media could be harmful for free newspapers as they provide a attractive alternative for young readers, the target group for free newspapers. There always has been a high overlap between the readership of free and paid newspapers, suggesting low substitution. Free newspapers seem to follow a pattern of a classic ‘life cycle’ model.
