Do Turkish women in the diaspora build social capital? Evidence from the Low countries

Abstract

Ever since Putnam (2000) made social capital a concept that should be mourned for its decline in the USA, researchers and policy makers in some western countries have adopted it as a solution to what they believe to be the failed practices of multiculturalism. Instead of preserving their individual cultures and traditions, critics would have them build social capital by bridging to people and institutions in their new countries and adopt the ‘shared values’ of the host countries and become ‘integrated’. This study, based on a study conducted in the Netherlands in 2006, and supplemented with survey findings from Flanders at the same time, examines whether this perspective is accurate, focusing on women migrants who live in the Low Countries (Netherlands and Flanders in Belgium), of the networks they have built or not and the reasons for that, and of the role of media and the internet in that process.     

VIS – A database on the distribution of fishes in inland and estuarine waters in Flanders,Belgium

The Research Institute for Nature and Forest (INBO) has been performing standardized fish stock assessments in Flanders, Belgium. This Flemish Fish Monitoring Network aims to assess fish populations in public waters at regular time intervals in both inland waters and estuaries. This monitoring was set up in support of the Water Framework Directive, the Habitat Directive, the Eel Regulation, the Red List of fishes, fish stock management, biodiversity research, and to assess the colonization and spreading of non-native fish species. The collected data are consolidated in the Fish Information System or VIS. From VIS, the occurrence data are now published at the INBO IPT as two datasets: ‘VIS - Fishes in inland waters in Flanders, Belgium’ and ‘VIS - Fishes in estuarine waters in Flanders, Belgium’. Together these datasets represent a complete overview of the distribution and abundance of fish species pertaining in Flanders from late 1992 to the end of 2012. This data paper discusses both datasets together, as both have a similar methodology and structure. The inland waters dataset contains over 350,000 fish observations, sampled between 1992 and 2012 from over 2,000 locations in inland rivers, streams, canals, and enclosed waters in Flanders. The dataset includes 64 fish species, as well as a number of non-target species (mainly crustaceans). The estuarine waters dataset contains over 44,000 fish observations, sampled between 1995 and 2012 from almost 50 locations in the estuaries of the rivers Yser and Scheldt (“Zeeschelde”), including two sampling sites in the Netherlands. The dataset includes 69 fish species and a number of non-target crustacean species. To foster broad and collaborative use, the data are dedicated to the public domain under a Creative Commons Zero waiver and reference the INBO norms for data use.

The influence of German idealistic morphology on the development of C.J. van der Klaauw's epistemology

Notwithstanding the general rise of experimental disciplines in biology in the first decades of our century, in Germany and in the Netherlands the interest in the idealistic morphological tradition flourished, and compensated for a reductionistic causal approach to natural phenomena. This article analyses the influence of the German idealistic morphologists W. Lubosch and A. Meyer on the development of C.J. van der Klaauw's epistemology. It discusses the gradual incorporation of non-causal principles into van der Klaauw's concept of biology. Van der Klaauw's epistemological concept of holistic biology was shaped in a critical confrontation with German idealistic morphology, and his early considerations can be interpreted as a direct impulse towards the development of his theory of functional components. Van der Klaauw's theories, being an alternative to the reductionistic experimental sciences, were among the causes of the fact that in the first half of our century biology in the Netherlands took a course deviating from the development of biology in the Anglo-American countries.     

A new methodology for compiling national Red Lists applied to butterflies (Lepidoptera, Rhopalocera) in Flanders (N-Belgium) and the Netherlands

The compilation of the Red Lists of butterflies in Flanders and the Netherlands was based on two criteria: a trend criterion (degree of decline) and a rarity criterion (actual distribution area). However, due to the large difference in mapping intensity in the two compared periods, a straightforward comparison of the number of grid cells in which each species was recorded, appeared inappropriate. To correct for mapping intensity we used reference species that are homogeneously distributed over the country, that have always been fairly common and that did not fluctuate in abundance too much during this century. For all resident species a relative presence in two compared periods was calculated, using the average number of grid cells in which these reference species were recorded as a correction factor. The use of a standardized method and well-defined quantitative criteria makes national Red Lists more objective and easier to re-evaluate in the future and facilitates the comparison of Red Lists among countries and among different organisms. The technique applied to correct for mapping intensity could be useful to other organisms when there is a large difference in mapping intensity between two periods.     

Evolutionary Morphology in Belgium

In historical literature, Edouard van Beneden (1846–1910) is mostly remembered for his cytological discoveries. Less well known, however, is that he also introduced evolutionary morphology – and indeed evolutionary theory as such – in the Belgian academic world. The introduction of this research programme cannot be understood without taking both the international and the national context into account. It was clearly the German example of the Jena University that inspired van Beneden in his research interests. The actual launch of evolutionary morphology at his University of Liège was, however, also connected with the dynamic of Belgian university reforms and the local rationale of creating a research “school.” Thanks to his networks, his mastering of the rhetoric of the “new” biology, his low ideological profile and his capitalising on the new academic élan in late-19th century Belgium, van Beneden managed to turn his programme into a local success from the 1870s onwards. Two decades later, however, the conceptual underpinnings of evolutionary morphology came under attack and the “Van Beneden School” lost much of its vitality. Despite this, van Beneden’s evolutionary morphology was prototypical for the research that was to come. He was one of the first scientific heavyweights in Belgium to turn the university laboratory into a centre of scientific practice and the hub of a research school.

Samenwerking tussen woonzorgcentra en voorzieningen voor personen met verstandelijke beperkingen

Considering the increasing life expectancy of people with intellectual disabilities (ID), the importance of cooperation between services for people with ID and elderly care services has been stressed in Flanders and the Netherlands, as well as internationally. However, the prevalence, intensity and content of such a cooperation are yet unknown. In order to gain information to address this issue, an online-survey was delivered to directors of all nursing homes in Flanders (n = 781). 229 surveys were completed.In more than 75% of the nursing homes, people with ID were among the residents over the past decade. However, at the same time a lack of expertise has been identified as a barrier to provide them optimal care and support. Hence, the respondents point out that a cooperation with ID care services could be beneficial. Nevertheless, those partnerships only arose in a quarter of the nursing homes so far, primarily for the purpose of exchange of expertise. Intersectoral multidisciplinary consultations and intersectoral care team consultations have been taking place as well, be it mainly in the context of a persons’ transition from an ID care service to a nursing home. Until now, radical cooperations which involve an exchange of staff, seem to be rather rare.     

Einthoven dissertation prizes 2014

For the 26th time in a row the Interuniversity Cardiology Institute of the Netherlands (ICIN-Netherlands Heart Institute) and the Netherlands Society of Cardiology (NVVC) have supported the competition for the best three cardiovascular PhD theses, published in the year 2014 [1–3]. The dissertation prize carries the name of one of the greatest Dutchmen in the history of cardiovascular medicine, Willem Einthoven, who in 1902 for the first time recorded the human ECG, for which he received the Nobel Prize in 1924 [4].This time the jury received a total of 28 PhD dissertations published in 2014. The jury members were very much impressed by the high scientific quality of the PhD fellows. The ultimate selection was based on a combination of several parameters: the curriculum vitae of the candidate, the scientific originality of the PhD thesis and its relevance for the cardiovascular field. In addition, several objective bibliometric parameters were used: (1) the number of articles in first-rate journals both in PubMed and the Web of Science (WOS), (2) the number of citations in WOS, (3) the Hirsch index and (4) the contribution as a first author (or shared first author).Based on a combination of these results, the jury finally selected three nominees: K.Y. van Spaendonck-Zwarts (University Medical Centre Groningen), N.M. van Mieghem (Erasmus Medical Centre, Rotterdam) and W.J. Dewilde (Sint Antonius Hospital, Nieuwegein).The members of the jury were: J.W. Deckers (Director CVOI), S. Heymans (ICIN professor), A. Mosterd (Chairman WCN), M.J. Schalij (Chairman Concilium NVVC) and V.A. Umans (President NVVC).The three candidates presented their Ph.D. theses at the annual spring meeting of the NVVC, held at the Congress Centre “De Leeuwenhorst” in Noordwijkerhout, 9–10 April 2015. Based on the quality of the presentation, the audience determined the ranking of the laureates. Mrs. dr. K.Y. van Speandonck-Zwarts received the third prize, dr. N.M. van Mieghem the second prize, and dr. W.J. Dewilde the first prize. We like to congratulate the three winners with their excellent PhD Theses. Summaries of the three nominated PhD theses are given below.     

PROTOPARMELIA HYPOTREMELLA,A NEW STERILE CORTICOLOUS SPECIES FROM EUROPE,AND ITS LICHENICOLOUS FUNGI

Protoparmelia hypotremellavan Herk, Spier & Wirth, a sterile corticolous lichen, is described as a species new to science, so far known from Austria, SW Germany and the Netherlands. It is rapidly spreading in Germany and the Netherlands. It is apparently close toP. oleagina, and is often found growing together with that species on oak trees along roads in the Netherlands. Both species are host to the lichenicolous fungiSphinctrina anglicaandTremella wirthii.     

Fluctuations in a coastal dune grassland due to fluctuations in rainfall: Experimental evidence

Experiments with rainfall on a dune grassland near Oostvoorne, the Netherlands with Festuco-Galietum as the main syntaxon are described. Both increase in rain through additional watering and decrease in rain through catchment are presented to plots belonging to the xerosere and the mesosere. Clear changes in the floristic composition are the result, even after only two years. Typical Festuco-Galietum species are promoted by high rainfall, species of open habitat such as Corynephorus canescens are promoted by drought. The results are discussed against the background of long term permanent plot observations in the area and a relation with rabbit grazing intensity is supposed.Nomenclature of vascular plants follows Heukels-van Ooststroom (1975) Flora van Nederland 18 ed., Woiters-Noordhoff, Groningen; Nomenclature of syntaxa follows Westhoff & den Held (1969).

Ethanol stimulates phospholipid turnover and inositol 1,4,5-trisphosphate production in Chlamydomonas eugametos gametes

Alcohols induce mating-structure activation in Chlamydomonas eugametos gametes. From the effect of ethanol on the ³²P-labelling of polyphosphoinositides, we conclude that the synthesis of these lipids is stimulated. Biologically inactive concentrations of ethanol (<6%) had no effect on synthesis, but 6–8% ethanol stimulated synthesis for upto 60 min. The ³²P incorporated into polyphosphoinositides and phosphatidic acid during ethanol treatment was readily chased out when 1 mM unlabelled Na₃PO₄ was added. Using a binding assay for inositol 1,4,5-trisphosphate, we show that the production of this phospholipid constituent is dramatically increased after ethanol treatment. This effect, coupled to a rise in intracellular calcium concentration, could explain gamete activation. The significance of these results in explaining other ethanol-induced phenomena in algae is discussed.Abbreviations Ins(1,4,5)P₃ inositol 1,4,5-trisphosphate - PtdA phosphatidic acid - PtdIns phosphatidylinositol - PtdIns(4)P phosphatidylinositol 4-phosphate - PtdIns(4,5)P₂ phosphatidylinositol 4,5-bisphosphate To whom correspondence should be addressedWe thank Dr. P. van Haastert (Biochemistry, University of Groningen, The Netherlands) and his colleagues for introducing us to their Ins(1,4,5)P₃ assay, and Ben ten Brink (Molecular Cell Biology, University of Amsterdam, The Netherlands) for information about contractile vacuoles.

The gonadotropic cells in the adenohypophysis of the blind mexican cave fish,Anoptichthys jordani

Summary The development and activity of the basophils in the meso-adenohypophysis of Anopthichthys jordani were studied in relation to the maturation of the gonads. In addition, pituitaries and ovaries of post-spawning females were studied during a period 0–11 days subsequent to spawning. The large and mainly PAS-positive basophilic cells in the meso-adenohypophysis were the only cell type that showed a correlation with the development and maturation of the ovaries and testes. These cells were subjected to a partial or complete degranulation in females following oviposition, when yolk formation in the ovary was at a maximum. It is concluded that the large PAS-positive basophils in the mesoadenohypophysis have a gonadotropic function and that only one gonadotropic cell type is present in the adenohypophysis of Anoptichthys jordani.This study was partly supported by a grant from the Netherlands Organization for the Advancement of Pure Research (Z.W.O.).I wish to express my gratitude to Prof. Dr. P. G. W. J. van Oordt for his active interest and constructive suggestions. Mr. R. van den Hurk and Miss Tjitske van Soelen provided valuable assistence in the course of the experiments. Mr. H. van Kooten made the photographs. Special thanks are due also to Mr. M. J. van Oosterum and Mr. J. Rowaan; without their capable and constant help it would have been hardly possible to obtain such satisfactory spawning results.     

Monitoring butterflies in the Netherlands and Flanders: the first results

Butterfly monitoring started in the Netherlands in 1990 and in Flanders in 1991. During the last few years butterflies have been counted at nearly 300 sites. This high number of transects makes it possible to calculate not only national, but also regional and habitat-indices for many species. Special attention is paid to Red list species in the Netherlands. In the near future the number of sites per species on this list is to be increased to at least 20. This can be achieved by a Red list monitoring scheme, in which monitoring is restricted to the flight period of the species.     

Dynamics and management of some coastal dune woodlands near The Hague,The Netherlands

Changes are reported of Crataegus-Betula dune woodlands between 1950–1980 from Meijendel, a calcareous coastal dune system near the city of The Hague, The Netherlands, which is used as a water catchment area. It concerns both woodlands in degradation stage and, more common, woodlands on the increase. Changes were recorded with help of successive vegetation maps, air photos and permanent plot observations. Woodland increase usually occurs on places with groundwater at or near the surface, either because of natural circumstances or as a result of artificial groundwater recharge through infiltration as part of the water catchment activities. The management of both types of woodland is discussed.Nomenclature follows Heukels-van der Meijden (1983), Flora van Nederland, 20th ed. Wolters-Noordhoff, Groningen.

Research Progress on Karst Tiankeng Ecosystems

The geomorphologic features called tiankengs were first discovered and named at the end of the twentieth century in karst areas of China. They have enjoyed increasing attention owing to their unusual geologic processes and unique ecological communities. However, the understanding of classification, geomorphic evolution, developmental conditions, geological dating and ecological environments of tiankengs are still extensively disputed by geomorphologists and geologists. This article focuses on combining all main areas of recent research activities from three aspects: development, evolution and transformation of karst tiankengs; biodiversity of karst tiankeng forests; and the impact of human activities on karst tiankeng ecosystems. Finally, we suggest future direction for research on karst tiankeng ecosystems: (1) multidisciplinary systematic study; (2) processes of ecological change and environmental effects under the influence of both natural and human impacts; (3) research on their protection, rational utilization, and sustainable management.     

A numerical-syntaxonomical study of the Calthion palustris Tx. 37 in the Netherlands

Summary After some remarks on ambiguities in the conventions of the Braun-Blanquet approach of phytosociology, a syntaxonomical study is presented of theCalthion palustris (wet grassland vegetation) of the Netherlands and surroundings. A numerical analysis of the non-optimal vegetation yielded a classification well comparable with the one established before. One new association is described. The pattern of variation in this dataset is compared in several ways with the one described elsewhere. Synoptic tables of different associations from several authors were compared by numerical analyses. The results suggested a large geographical variation within theCalthion of Western Europe.The authors wish to thank Mr H.M. van der Steeg (Nijmegen) and Mr J.C. Smittenberg (Assen) for kindly placing some unpublished relevés at their disposal, as well as several members of the plant sociology working group of the Nederlandse Jeugdbond voor Natuurstudie.     

Selection for biennial life histories in plants

The applicability of traditional models of life-history evolution is restricted because models assume constant environments without density-dependence. In these models the geometric growth rate () of a lineage is the natural choice for the fitness criterion. Because in growing populations is very sensitive to changes in generation time, biennials appear at a disadvantage when compared to species with annual reproduction. We propose an alternative fitness criterion for the situation in which recruitment is limited by both the availability of seeds and the (constant) rate at which safe sites for establishment are created by small-scale disturbances. Under the assumptions of the model the evolutionarily stable strategy is to maximize expected seed production, irrespective of the length of the life cycle. For monocarpic plants, this implies that delay of flowering is favourable if the increased seed production compensates for the death of rosettes.Publication of the Meijendel comité, New series No. 89.Nomenclature follows Heukels & van der Meijden (1983), Flora van Nederland, Wolters Noordhoff, Groningen.We would like to thank Prof. K.
