Dutch Moroccan websites: A transnational imagery?

In the last few years, second-generation migrants in the Netherlands have started to set up their own websites, in particular Dutch Moroccan youth. These developments have changed the old phenomenon of migration, making new communication technology a special feature of the concept of transnationalism. For migrants, the Internet is an excellent tool to ally themselves with compatriots throughout the world. This paper focuses on how the second generation of migrants uses discussion boards of websites to express their ties with their country of origin; thus websites are examples of cultural artefacts that can be seen as a virtual way of keeping alive the image of Morocco. Two websites, Maroc.nl and Maghreb.nl, show how Dutch Moroccan youth express their loyalty and belonging to Morocco. They use these websites as a source of information and imagination, therefore the sites function as a binding factor in a Dutch social context. In fact, what these particular websites keep together is not the transnational but the national network of Dutch Moroccan youths

HDAC 3-selective inhibitor RGFP966 demonstrates anti-inflammatory properties in RAW 264.7 macrophages and mouse precision-cut lung slices by attenuating NF-κB p65 transcriptional activity

AbstractThe increasing number of patients suffering from chronic obstructive pulmonary disease (COPD) represents a major and increasing health problem. Therefore, novel therapeutic approaches are needed. Class I HDACs 1, 2 and 3 play key roles in the regulation of inflammatory gene expression with a particular pro-inflammatory role for HDAC 3. HDAC 3 has been reported to be an important player in inflammation by deacetylating NF-κB p65, which has been implicated in the pathology of COPD. Here, we applied the pharmacological HDAC 3-selective inhibitor RGFP966, which attenuated pro-inflammatory gene expression in models for inflammatory lung diseases. Consistent with this, a robust decrease of the transcriptional activity of NF-κB p65 was observed. HDAC 3 inhibition affected neither the acetylation status of NF-κB p65 nor histone H3 or histone H4. This indicates that HDAC 3 inhibition does not inhibit NF-κB p65 transcriptional activity by affecting its deacetylation but rather by inhibiting enzymatic activity of HDAC 3. Taken together, our findings indicate that pharmacological HDAC 3-selective inhibition by inhibitors such as RGFP966 may provide a novel and effective approach toward development of therapeutics for inflammatory lung diseases

Climate variability and human impact in South America during the last 2000 years: synthesis and perspectives from pollen records

An improved understanding of present-day climate variability and change relies on high-quality data sets from the past 2 millennia. Global efforts to model regional climate modes are in the process of being validated against, and integrated with, records of past vegetation change. For South America, however, the full potential of vegetation records for evaluating and improving climate models has hitherto not been sufficiently acknowledged due to an absence of information on the spatial and temporal coverage of study sites. This paper therefore serves as a guide to high-quality pollen records that capture environmental variability during the last 2 millennia. We identify 60 vegetation (pollen) records from across South America which satisfy geochronological requirements set out for climate modelling, and we discuss their sensitivity to the spatial signature of climate modes throughout the continent. Diverse patterns of vegetation response to climate change are observed, with more similar patterns of change in the lowlands and varying intensity and direction of responses in the highlands. Pollen records display local-scale responses to climate modes; thus, it is necessary to understand how vegetation–climate interactions might diverge under variable settings. We provide a qualitative translation from pollen metrics to climate variables. Additionally, pollen is an excellent indicator of human impact through time. We discuss evidence for human land use in pollen records and provide an overview considered useful for archaeological hypothesis testing and important in distinguishing natural from anthropogenically driven vegetation change. We stress the need for the palynological community to be more familiar with climate variability patterns to correctly attribute the potential causes of observed vegetation dynamics. This manuscript forms part of the wider LOng-Term multi-proxy climate REconstructions and Dynamics in South America – 2k initiative that provides the ideal framework for the integration of the various palaeoclimatic subdisciplines and palaeo-science, thereby jump-starting and fostering multidisciplinary research into environmental change on centennial and millennial timescales

Aquatic community response to volcanic eruptions on the Ecuadorian Andean flank: evidence from the palaeoecological record

Aquatic ecosystems in the tropical Andes are under increasing pressure from human modification of the landscape (deforestation and dams) and climatic change (increase of extreme events and 1.5 °C on average temperatures are projected for AD 2100). However, the resilience of these ecosystems to perturbations is poorly understood. Here we use a multi-proxy palaeoecological approach to assess the response of aquatic ecosystems to a major mechanism for natural disturbance, volcanic ash deposition. Specifically, we present data from two Neotropical lakes located on the eastern Andean flank of Ecuador. Laguna Pindo (1°27.132′S–78°04.847′W) is a tectonically formed closed basin surrounded by a dense mid-elevation forest, whereas Laguna Baños (0°19.328′S–78°09.175′W) is a glacially formed lake with an inflow and outflow in high Andean Páramo grasslands. In each lake we examined the dynamics of chironomids and other aquatic and semi-aquatic organisms to explore the effect of thick (> 5 cm) volcanic deposits on the aquatic communities in these two systems with different catchment features. In both lakes past volcanic ash deposition was evident from four large tephras dated to c.850 cal year BP (Pindo), and 4600, 3600 and 1500 cal year BP (Baños). Examination of the chironomid and aquatic assemblages before and after the ash depositions revealed no shift in composition at Pindo, but a major change at Baños occurred after the last event around 1500 cal year BP. Chironomids at Baños changed from an assemblage dominated by Pseudochironomus and Polypedilum nubifer-type to Cricotopus/Paratrichocladius type-II, and such a dominance lasted for approximately 380 years. We suggest that, despite potential changes in the water chemistry, the major effect on the chironomid community resulted from the thickness of the tephra being deposited, which acted to shallow the water body beyond a depth threshold. Changes in the aquatic flora and fauna at the base of the trophic chain can promote cascade effects that may deteriorate the ecosystem, especially when already influenced by human activities, such as deforestation and dams, which is frequent in the high Andes

Climate change and cultural resilience in late pre-Columbian Amazonia

The long term response of ancient societies to climate change has been a matter of global debate. Until recently, the lack of integrative studies between archaeological, palaeoecological, and palaeoclimatological data had prevented an evaluation of the relationship between climate change, distinct subsistence strategies, and cultural transformations across the largest rainforest of the world, Amazonia. Here, we review the most relevant cultural changes seen in the archaeological record of six different regions within Greater Amazonia during late pre-Columbian times. We compare the chronology of those cultural transitions with high-resolution regional palaeoclimate proxies, showing that, while some societies faced major reorganisation during periods of climate change, others were unaffected and even flourished. We propose that societies with intensive, specialised land-use systems were vulnerable to transient climate change. In contrast, land-use systems that relied primarily on polyculture agroforestry, resulting in the formation of enriched forests and fertile Amazonian Dark Earths in the long term, were more resilient to climate change

Secret seducers - True tales of pimps in the red light district of Amsterdam

At the end of the 1990s, a moral panic erupted in the Netherlands about the phenomenon of what came to be known as 'loverboys'. The suspicion was that a growing number of Dutch girls were being groomed by handsome young men who employed all sorts of devious methods to prepare their girlfriends for life as a prostitute. Stories about a new generation of pimps, often of Moroccan origin, regularly appeared in the Dutch media. In this article, based on ethnographic fieldwork on pimps operating in the red-light district of Amsterdam, we describe the ways in which these young men operate and how they justify their behaviour. On the basis of empirical research we intend to present a more realistic picture of what goes on in the prostitution industry and highlight the discrepancy between what is reported in the media and what is actually happening in the prostitution sector. We also examine the background to the moral panic about loverboys and the ways in which these young men were supposedly able to induce many young girls into becoming prostitutes

Stability and change the role of keepsakes and family homes in the lives of parentally bereaved young adults in the Netherlands 1

This paper examines the loss of a parent in young adulthood, showing how this emergent and distinctive life stage shapes Dutch young people’s experience of bereavement. Youth material cultures have commonly been analysed in terms of the construction and expression of youth identities, for example, through style, music and leisure. In this research, we highlight three themes in young people’s relationship to material culture as part of their everyday lived experience of parental loss: first, the parental home as a space of departure, memory and return, and the potential for conflict, destabilisation and misunderstanding when the remaining parent transforms the home or embarks on a new relationship; second, the different strategies young adults use to commemorate their parent in their own temporary or shared accommodation and online space; and third, the role of small, portable but effective keepsakes and adornment, such as jewellery or tattoos, that meet their need for the emotional experience of closeness with the memory of their parent. A focus on the material trajectories of grief grants insights into how young adults cope with loss in their everyday life, generating understanding of the ways young people may support themselves and be supported by others in the context of parental bereavement
