The damaging 1932 Uden Earthquake in the Netherlands – revision of cross‑border macroseismic data and its impact on source parameters
No full textA re-assessment of the macroseismic intensity data was conducted for the second-largest instrumentally recorded event in the Netherlands: the 20 November 1932 Uden earthquake. This event was felt across the Netherlands, Belgium and Germany. Intensity values on the EMS98 scale were assigned based on original data (reports/enquiries/letters), manually for the Netherlands and automatically for Belgium, with existing German data added for completeness. The updated dataset was used to calculate macroseismic location and magnitude using the Bakun and Wentworth (1997, 1999) algorithm. To capture epistemic uncertainty, four newly calibrated intensity attenuation relations were applied and their results averaged. The results using only intensity data from the Netherlands provided stable solutions within the region of maximum observed intensity ( Imax = VII). However, including Belgian and German data shifted the source location outside this region and becomes less reliable, likely due to differences in data collection methods and local/regional site effects. Comparison of confidence levels from the BW method with bootstrap modelling showed that almost all bootstrap results fall within the 50% confidence region. A more realistic estimate for the location uncertainty was derived from the bootstrap analysis. The revised source parameters are 51.63°N and 5.61°E ± 7.3 km for the source location and ML = 5.1 ± 0.3 ( MS 4.9 ± 0.3) for the magnitude

Diffusion of a Social Norm: Tracing the Emergence of the Housewife in the Netherlands, 1812-1922
No full textThe emergence of the housewife in the Netherlands over the period 1812-1922 was strongly influenced by the social norm that women should withdraw from the labour market on the eve of marriage. Adherence to this norm is most clearly reflected in the emergence of the housewife among the lower classes, especially at the close of the nineteenth century among wives of farmers.
Women in urban municipalities, however, set the norm far earlier and differences across social classes were significantly larger in towns than in rural areas. Paradoxically, the rise of the housewife did not change work pressures for lower–class women. This paradox is resolved by noting that they substituted registered work for unregistered work, e.g., in house industries, working in the family firm or farm
Data presented in the paper "Colony-breeding Eurasian spoonbills in the Netherlands: local limits to population growth with expansion into new areas"
No full textThe dataset contains three files, all relating to spoonbill breeding colonies in the Netherlands. We used this dataset to assess population growth of Spoonbills in the Netherlands, and especially in the Wadden Sea. The first file contains yearly breeding colony sizes, which were obtained by counting in each of the colonies in each year the number of breeding pairs. This was done mostly by local nature management teams. The second file contains for several colonies in the Wadden Sea area the average yearly breeding success. This number was obntained by counting the number of fledglings in the ebnd of the breeding season. This was also done mainly by local nature management teams. The last file contains data on the condition of individual chicks in several colonies. These were obtained by researchers from the University of Groningen and NIOZ, and by several Staatsbosbeheer officers
The Central Institute for Brain Research in Amsterdam and its directors
No full textItem does not contain fulltextThe Central Institute for Brain Research was founded in Amsterdam in 1908 as part of an international effort to study the nervous system with multiple institutions and various disciplines. The development of research in the past hundred years at the Brain Institute has hardly been documented. We analyze the history of this institute by means of brief portraits of its directors and their main research topics. It appears that each director introduced his own branch of neuroscience into the institute. Initially, mainly comparative neuroanatomical data were collected. Following the Second World War, the multidisciplinary approach slowly developed with research programs on systems neuroscience, neuroendocrinology, and brain disorders. Every new director introduced new approaches to the study of the brain and thus played an important role in keeping brain research in the Netherlands at the international forefront where it has been ever since its foundation in 1908.11 p
Ex-ante evaluation of tightening environmental policy: the case of mineral use in Dutch agriculture
No full textNon-point source pollution is notoriously difficult to asses. A relevant example is mineral emissions in the Netherlands. Since the mid 1980s the Dutch government has sought to reduce emissions through a wide variety of measures, the effect of which in turn is monitored using modeling techniques. This paper presents the current generation of mineral emission models from agriculture based on microsimulation of farms in combination with a spatial equilibrium model for the dispersion of manure from excess regions with high livestock intensities within the country to areas with low livestock intensities. The micro-simulation approach retains the richness in the heterogeneity of farm household decision making that are the core cause of the difficulty of assessing non-point source pollution, while using the best available data to track corresponding pollution. Using scenario analysis we are able to assess the possible effects of further tightening of agro-environmental policy.micro-simulation, spatial-equilibrium model, non-point source pollution, Environmental Economics and Policy,
Long-term seed production data of European beeches in the National Park De Hoge Veluwe, Netherlands
No full textSeed production of European beech (Fagus sylvatica) is assessed yearly by the Netherlands Institute of Ecology (NIOO-KNAW) since 1976. The data contains individual-level information on beechnut production of a selected set of trees in the National Park De Hoge Veluwe, Netherlands, consisting of counts and weights
The Old and the Stubborn? Firm Characteristics and Relocation in the Netherlands
No full textThis study gives some insight into the relationships between the spatial environment, firm characteristics and long term existence of firms in the Netherlands. A logit model is employed to investigate the locational difference of firms, considering firm characteristics such as age, size, region and network. The main findings are that (long-term) continuation of the location and firm size are positively associated with long-term existence of firms
Netherlands Kinship Panel Study - wave 3 - 2010-2011: A Multi-Actor, Multi-Method Panel Study on Solidarity in Family Relationships
No full textThe Netherlands Kinship Panel Study is a survey meant to improve our understanding of the dynamics of family relationships in the Netherlands. The NKPS-data are collected from multiple actors, by multiple methods, and at multiple points in time.
- Multi-actor. This implies that the focus is on relationships and networks of relationships rather than on individuals. Data are collected from individual respondents (so-called Anchors) as well as from family members (so-called Survey Alters). Survey Alters are: the partner, a maximum of two children aged 15 and over, father/mother, and a brother/sister aged 15 and over. Survey Alters do not necessarily co-reside with the Anchor.
- Multi-method. A large-scale survey with pre-structured questions is complemented with in-depth studies (mini-panels) using flexible interview schedules. In the survey, the data are collected by means of face-to-face interviews and self-completion questionnaires.
- Panel. Relationships are in constant flux. The NKPS is a panel study in order to understand the dynamic nature of family solidarity and to study causes and effects of solidarity within family relationships. Waves are spaced three years apart.
The data for the third wave of the NKPS consists of information on 4,390 respondents who were between 18 and 79 years of age at the time of the first wave (2002-2004). The data for wave 3 were collected in 2010 and 2011. The data can be linked to data from wave 1 and wave 2 by a personal identification code.
The data from the NKPS are freely accessible via the NKPS website to researchers affiliated with academic and (semi-)government organizations. To access the data files researchers must have registered as NKPS data users and have undersigned the NKPS privacy policy. No one has any exclusive right or priority to use the NKPS to work on any research question
