Management Issues

A trend towards performance-based contracting (PBC) can be observed in public infrastructure maintenance. PBC is an approach of tying the contractor’s payment to specified performance. We investigated PBC for the maintenance of highways and roads in the Netherlands, identifying issues ultimately resulting in poor contractor performance. The PBC-induced risks for clients relate to the problematic translation and measurement of specifications, the ineffectiveness of incentives, the avoidance of contractors taking full responsibility, and contract management issues. Clients should recognize the actual balance of power in the relationship with their (main) contractors, and take appropriate measures.

This interview with Martin van Bruinessen records his personal and intellectual engagement with Alevis in Turkey and the Netherlands for over fifty years. Initially, his interest was in Anatolian Alevi culture and he began exploring the religious dimension of Alevism in the 1970s at a time when Alevis were more preoccupied with left-wing politics. He charts the emergence of Alevism studies since the 1980s and links it to the religious resurgence and reinvention of diverse ethno-religious Alevi identities associated with urbanised and diasporic communities. He further examines the relationship between Kurdish and Alevi movements and Alevism and Islam.

Spatial Stratification

Whereas the so-called ‘citizenship premium’ in the labour market has been widely studied, we know little about how naturalisation affects immigrants’ lives beyond work and income. Focusing on the Netherlands, this paper analyses the relationship between citizenship acquisition and immigrant residential mobility, in particular the propensity of immigrants to move away from areas with high concentrations of migrants. We draw on register data from Statistics Netherlands ( N = 234,912). We argue that possessing Dutch citizenship reduces spatial stratification by diminishing the risk of housing market discrimination, thereby facilitating mobility outside of migrant-concentrated areas. Our findings show that naturalised immigrants are 50% more likely to move out of concentrated neighbourhoods, all else constant. The effect of naturalisation is especially relevant for renting without housing benefits and for home ownership, and for mid-risk immigrants who earn around the median income and hold permanent jobs, whose applications face strong scrutiny from landlords, rental agencies and mortgage lenders.

Level Of Risk

The relationship between risk-taking behavior, alcohol consumption and negative alcohol-related consequences is well known. The current analyses were conducted to investigate whether alcohol mixed with energy drink (AMED) is related to risk-taking behavior and if there is a relationship between the amount of energy drink mixed with alcohol consumed, risk-taking behavior and negative alcohol-related consequences. Data from N = 1276 AMED consuming students from the Netherlands, UK and Australia who completed the same survey were evaluated. The analysis revealed that, compared to AMED occasions, on alcohol only (AO) occasions significantly more alcohol was consumed and significantly more negative alcohol-related consequences were reported. On both AO and AMED occasions, there was a strong and positive relationship between amount of alcohol consumed, level of risk-taking behavior and number of reported negative alcohol-related consequences. In contrast, the level of risk-taking behavior was not clearly related to energy drink consumption. Across risk-taking levels, differences in the amount of energy drink consumed on AMED occasions did not exceed one 250 mL serving of energy drink. When correcting for the amount of alcohol consumed, there were no statistically significant differences in the number of energy drinks consumed on AMED occasions between the risk-taking groups. In conclusion, alcohol consumption is clearly related to risk-taking behavior and experiencing negative alcohol-related consequences. In contrast, energy drink intake was not related to level of risk-taking behavior and only weakly related to the number of experienced negative alcohol-related consequences.

Cette Attitude

RÉSUMÉA l'aide de huit critères mesurant la «réceptivité au soutien informel,» cette étude examine les attitudes de personnes âgées de 65 ans et plus, vivant de façon autonome, par rapport aux soins formels et informels. Ces travaux examinent de plus la relation entre ces attitudes et les préférences quant à la panoplie de soins dans diverses situations (hypothétiques) où les soins nécessaires différent quant à leur nature et leur durée prévue. Au-delà de l'expérience de la personne âgée quant aux soins antérieurement reçus, de ses caractéristiques individuelles et sociales, les attitudes envers les soins s'avèrent être en eux-mêmes un puissant indicateur des préférences des personnes âgées en matière de soins. Les décideurs peuvent utiliser cette attitude envers les soins comme instrument permettant de guider à long terme les préférences et le recours des personnes âgées à ces services de soins.

The Relationship

Forty-seven isolates of Ceratocystis ulmi collected from Canada, the United States, the United Kingdom, France, the Netherlands, and Iran were classified with respect to their ability to produce cerato-ulmin (CU) and synnemata, their radial growth, mycelial habit, and pathogenicity.Twenty-nine isolates clearly produced CU in a measurable quantity while 18 isolates produced it only in trace quantities. In general, the former produced fluffy mycelium and were active in synnemata formation. They were aggressive in pathogenicity with one exception. The latter group of isolates generally produced waxy, yeastlike mycelium and formed very few synnemata. They were all nonaggressive in pathogenicity. Radial growth was generally higher among the isolates that produced CU in larger quantities than among those producing CU in trace quantities. The relationship between CU production and pathogenicity affords a method for estimating isolate pathogenicity without the need for host inoculation.

Summary In this paper some theories on tenses are described. These theories appeared in the Netherlands in the first half of the 19th century. The purpose is not just describing the different tense-systems of P. Weiland (1805), W. Bilderdijk (1826), W. G. Brill (1846) and L. A. te Winkel (1866). In the first half of the 19th century some fundamental changes took place. It is shown that these changes are based upon continuity of research of time and tense in the Dutch tradition. This continuity is found on three levels: (a) The research was concentrated on the verbal forms, no other information from the sentence was used. (b) The grammarians took the relationship between linguistic forms and logical categories as a one-to-one relation. (c) The morphological form of the Dutch language determined the grammatical representation of the tense-systems more and more.

Pm2.5 Concentration

Abstract. To acquire daily estimates of PM2.5 distributions based on satellite data one depends critically on an established relation between AOD and ground level PM2.5. In this study we aimed to experimentally establish the AOD-PM2.5 relationship for the Netherlands. For that purpose an experiment was set-up at the AERONET site Cabauw. The average PM2.5 concentration during this ten month study was 18 μg/m3, which confirms that the Netherlands are characterised by a high PM burden. A first inspection of the AERONET level 1.5 (L1.5) AOD and PM2.5 data at Cabauw showed a low correlation between the two properties. However, after screening for cloud contamination in the AERONET L1.5 data, the correlation improved substantially. When also constraining the dataset to data points acquired around noon, the correlation between AOD and PM2.5 amounted to R2=0.6 for situations with fair weather. This indicates that AOD data contain information about the temporal evolution of PM2.5. We had used LIDAR observations to detect residual cloud contamination in the AERONET L1.5 data. Comparison of our cloud-screed L1.5 with AERONET L2 data that became available near the end of the study showed favorable agreement. The final relation found for Cabauw is PM2.5=124.5*AOD–0.34 (with PM2.5 in μg/m3) and is valid for fair weather conditions. The relationship determined between MODIS AOD and ground level PM2.5 at Cabauw is very similar to that based on the much larger dataset from the sun photometer data, after correcting for a systematic overestimation of the MODIS data of 0.05. We applied the relationship to a MODIS composite map to assess the PM2.5 distribution over the Netherlands. Spatial dependent systematic errors in the MODIS AOD, probably related to variability in surface reflectance, hamper a meaningful analysis of the spatial distribution of PM2.5 using AOD data at the scale of the Netherlands.
