Population dynamics of the liver fluke, Fasciola hepatica: the effect of time and spatial separation on the genetic diversity of fluke populations in the Netherlands

An evaluation of the genetic diversity within Fasciola hepatica (liver fluke) may provide an insight into its potential to respond to environmental changes, such as anthelmintic use or climate change. In this study, we determined the mitochondrial DNA haplotypes of >400 flukes from 29 individual cattle, from 2 farms in the Netherlands, as an exemplar of fasciolosis in a European context. Analysis of this dataset has provided us with a measure of the genetic variation within infrapopulations (individual hosts) and the diversity between infrapopulations within a herd of cattle. Temporal sampling from one farm allowed for the measurement of the stability of genetic variation at a single location, whilst the comparison between the two farms provided information on the variation in relation to distance and previous anthelmintic regimes. We showed that the liver fluke population in this region is predominantly linked to 2 distinct clades. Individual infrapopulations contain a leptokurtic distribution of genetically diverse flukes. The haplotypes present on a farm have been shown to change significantly over a relatively short time-period.

Predicting the past: Understanding the causes of bank distress in the Netherlands in the 1920s

Why do some banks fail in financial crises while others survive? This article answers this question by analysing the effect of the Dutch financial crisis of the 1920s on 142 banks, of which 33 failed. We find that choices of balance sheet composition and product market strategy made in the lead-up to the crisis had a significant impact on banks’ subsequent chances of experiencing distress. We document that high-risk banks – those operating highly-leveraged portfolios and attracting large quantities of deposits – were more likely to fail. Branching and international activities also increased banks’ default probabilities. We measure the effects of board interlocks, which have been characterized in the extant literature as contributing to the Dutch crisis. We find that boards mattered: failing banks had smaller boards, shared directors with smaller and very profitable banks and had a lower concentration of interlocking directorates in non-financial firms.

Detection of Lateglacial distal tephra layers in the Netherlands

Three distal tephra layers or cryptotephras have been detected within a sedimentary sequence from the Netherlands that spans the last glacial-interglacial transition. Geochemical analyses identify one as the Vedde Ash, which represents the southernmost discovery of this mid-Younger Dryas tephra so far. This tephra was found as a distinct horizon in three different cores sampled within the basin. The remaining two tephras have not been geochemically ‘fingerprinted’, partly due to low concentrations and uneven distributions of shards within the sequences sampled. Nevertheless, there is the potential for tracing these tephra layers throughout the Netherlands and into other parts of continental Europe. Accordingly, the possibilities for precise correlation of Dutch palaeoenvironmental records with other continental, marine and ice-core records from the North Atlantic region are highlighted.

Female narratives of ‘new’ citizens’ belonging(s) and identities in Europe: case studies from the Netherlands and Britain

Public discourses on citizenship, identity and nationality, which link geographical borders and the political boundaries of a community, are infused with tensions and contradictions. This paper illustrates how these tensions are interwoven with multilayered notions of home, belonging, migration, citizenship and individual’s ‘longing just to be’, focusing on the Dutch and the British context. The narratives of a number of Dutch and British women, who either immigrated to the respective countries or were born to immigrants, illustrate how the growing rigid integration and assimilative discourses in Europe contradict an individual anchoring in national and local communities. The narratives of women participating in these studies show multilayered angles of belonging presenting an alternative to the increasing strong argument for a fixed notion of positioning and national belonging. The female ‘new’ citizens in our study tell stories of individual choices, social mobility and a sense of multiple belonging in and across different communities.

The Long Distance Transport of Airborne Ambrosia Pollen to the UK and the Netherlands from Central and South Europe

Background: The invasive alien species Ambrosia artemisiifolia (common or short ragweed) is increasing its range in Europe. In the UK and the Netherlands airborne concentrations of Ambrosia pollen are usually low. However, more than 30 Ambrosia pollen grains per cubic metre of air (above the level capable to trigger allergic symptoms) were recorded in Leicester (UK) and Leiden (NL) on 4 and 5 September 2014. Objective: The aims of this study were to determine whether the highly allergenic Ambrosia pollen recorded during the episode could be the result of long distance transport, to identify the potential sources of these pollen grains and describe the conditions that facilitated this possible long distance transport. Methods: Airborne Ambrosia pollen data were collected at 10 sites in Europe. Back trajectory and atmospheric dispersion calculations were performed using HYSPLIT_4. Results: Back trajectories calculated at Leicester and Leiden show that higher altitude air masses (1500m) originated from source areas on the Pannonian Plain and Ukraine. During the episode, air masses veered to the west and passed over the Rhône Valley. Dispersion calculations showed that the atmospheric conditions were suitable for Ambrosia pollen released from the Pannonian Plain and the Rhône Valley to reach the higher levels and enter the air stream moving to Northwest Europe where they were deposited at ground level and recorded by monitoring sites. Conclusions: The study indicates that the Ambrosia pollen grains recorded during the episode in Leicester and Leiden were probably not produced by local sources, but transported long distances from potential source regions in East Europe, i.e. the Pannonian Plain and Ukraine, as well as the Rhône Valley in France.

The Political and Artistic Program of Prince Petru Rares of Moldavia (1527-1538 and 1541-1546) and the Fresco Series Depicting the “Life of the Mother of God” in the Church of Humor Monastery

En 1993, l’église du monastère Humor et six autres églises du nord de la Moldavie (Roumanie) ont été classifiés comme patrimoine de l'UNESCO, en particulier en raison de leurs caractéristiques iconographiques et architecturales uniques. Construit au seizième siècle, le monastère Humor est devenu un riche centre religieux et culturel sous le patronage du prince Petru Rares de Moldavie. Ce centre a encouragé les innovations architecturales ecclésiales, ainsi qu’un programme très prolifique de fresques, extérieures et intérieures, exprimant une créativité au-delà du canon de la peinture de l'époque. La présente thèse est concentrée sur ces innovations architecturales et iconographiques, comprises à la lumière du contexte historique de ce moment unique dans l'histoire de la Moldavie, dans le siècle qui suivit la chute de Constantinople (1453). Tandis que la première partie de la thèse est concentrée sur ces circonstances historiques, et plus précisément sur l'impact du patronage du Prince Rares, la deuxième partie de la recherche est concentrée sur l'analyse des sources littéraires et de la théologie d’une série unique de fresques, placé dans la gropnita (chambre funéraire) de l’église monastique d’Humor, évoquant la vie de la Mère de Dieu. La série est un exemple extraordinaire d’interaction des textes, le Protévangile de Jacques et le Synaxarion, avec l'iconographie. Une attention particulière à l'iconographie du monastère Humor démontre le besoin de la corrélation entre texte et icône d'une part, ainsi que la nécessité d’une corrélation entre les études théologiques, l'art et l’histoire d’autre part. Un autre avantage de la recherche est de contribuer à une appréciation plus riche des trésors culturels et religieux des communautés chrétiennes de l'Europe de l'Est aux points de vue religieux et culturel, en réponse à leur reconnaissance comme patrimoine de l’UNESCO.
