Transnational Solidarity, Migration, and the Refugee Crisis: (In)Formal Organising and Political Environments in Greece, Germany, and Denmark

Over the last decade, the unprecedented influx of refugees and migrants into the European Union has posed a significant challenge to Europe, with solidarity being contested at two fronts: first, the question of solidarity with refugees in terms of meeting adequate measures of protection and satisfying their elementary needs; and second, the question of solidarity within the European Union in terms of sharing the costs and burden of hosting these refugees among the member states. One driving factor of these contestations is that the solidarity challenge in facing the ‘refugee crisis’ is taken up differently in transit countries in the South of Europe and destination countries in the North. Wishing to shed light on how national contexts impact transnational solidarity organising, we draw on a fresh set of cross-national evidence from a random sample of 277 transnational solidarity organisations (TSOs) in Greece, Germany, and Denmark. The aim is to illustrate the effects of political opportunities and threats during the 2007–2016 crises period on migration-related solidarity activities organised by TSOs. We will do so through tri-national comparisons tracing the patterns in which migration-related TSOs appear through time. The data used is produced in the context of the TRANSSOL project by a new methodological approach (action organisation analysis) based on hubs-retrieved organisational websites and their subsequent content analysis

Civil Society Activism in Italy Across Different Fields: A Multifaceted Picture of Solidarity in Hard Times

Over the last years, Italian civil society organisations have been working on a daily basis to mitigate the impact of both the global economic crisis and the refugee crisis, which have increased social vulnerabilities. Relying on the data gathered through 30 in-depth interviews with transnational solidarity organisations’ representatives, this chapter analyses solidarity practices in three fields of activity: disability, unemployment and migration. Results show that solidarity attitudes, practices and discourses are strongly influenced by the policy domain in which the organisations are active. Furthermore, the crisis led organisations to search for new strategies and approaches, even though it has been an ineffective vector of transnationalisation due to lack of resources, and the necessity to cope with pressing needs at national and local level/s.Results presented in book have been obtained through the project ‘European paths to transnational solidarity at times of crisis: Conditions, forms, role-models and policy responses’ (TransSOL).

Corrigendum to “Pollen-based paleoenvironmental and paleoclimatic change at Lake Ohrid (south-eastern Europe) during the past 500 ka” published in Biogeosciences, 13, 1423–1437, 2016

In this corrigendum we report an updated pollen record from the Lake Ohrid DEEP site spanning the past 500 ka whereby we have reprocessed and re-analyzed 104 samples affected by chemical procedure problems that occurred in one palynological laboratory. Firstly, these samples were affected by the use of wrong containers, causing in- adequate settling of particles at the set centrifuging speed. Secondly, HCl and HF treatments were combined without the prescribed intermediate centrifuging and decanting steps. The inaccuracy in the protocol resulted in the loss of smaller pollen grains and in the overrepresentation of bisaccate ones in most of the re-analyzed samples. We therefore provide an updated set of figures with the new data and have revised the description of the results, discussion and conclusions re- ported in Sadori et al. (2016) where necessary. We stress that the majority of the original results and conclusions remain valid, while the records’ reliability and resolution have improved as 12 samples that had been omitted in the original study because of low count sums are now included in the revised dataset (Sadori et al., 2018)

Photodynamic Therapy Can Induce a Protective Innate Immune Response against Murine Bacterial Arthritis via Neutrophil Accumulation

Background: Local microbial infections induced by multiple-drug-resistant bacteria in the orthopedic field can be intractable, therefore development of new therapeutic modalities is needed. Photodynamic therapy (PDT) is a promising alternative modality to antibiotics for intractable microbial infections, and we recently reported that PDT has the potential to accumulate neutrophils into the infected site which leads to resolution of the infection. PDT for cancer has long been known to be able to stimulate the innate and adaptive arms of the immune system. Methodology/Principal Findings: In the present study, a murine methicillin-resistant Staphylococcus aureus (MRSA) arthritis model using bioluminescent MRSA and polystyrene microparticles was established, and both the therapeutic (Th-PDT) and preventive (Pre-PDT) effects of PDT using methylene blue as photosensitizer were examined. Although Th-PDT could not demonstrate direct bacterial killing, neutrophils were accumulated into the infectious joint space after PDT and MRSA arthritis was reduced. With the preconditioning Pre-PDT regimen, neutrophils were quickly accumulated into the joint immediately after bacterial inoculation and bacterial growth was suppressed and the establishment of infection was inhibited. Conclusions/Significance: This is the first demonstration of a protective innate immune response against a bacterial pathogen produced by PDT.National Institutes of Health (U.S.) (Grant number R01AI050875

Changing Fields of Solidarity in France: A Cross-field Analysis of Migration, Unemployment and Disability

AbstractThis chapter evaluates the implications of recent crises for solidarity organisations in France. The main aim is to assess whether solidarity remains nationally bounded or otherwise follows some consistent pattern of transnationalisation. By focusing on the fields of migration, unemployment and disability, the chapter examines the main attributes of solidarity organisations; in particular, the analysis aims to evaluate how transnational features relate to endogenous characteristics, such as activities, roles and networks affecting their particular experiences within changing fields of solidarity. Crucially, findings show that the economic crisis and welfare retrenchment in France have well served the purpose of governments willing to pre-empt strong political challenge by potential solidarity movements

Mediterranean winter rainfall in phase with African monsoons during the past 1.36 million years

Mediterranean climates are characterized by strong seasonal contrasts between dry summers and wet winters. Changes in winter rainfall are critical for regional socioeconomic development, but are difficult to simulate accurately1 and reconstruct on Quaternary timescales. This is partly because regional hydroclimate records that cover multiple glacial–interglacial cycles2,3 with different orbital geometries, global ice volume and atmospheric greenhouse gas concentrations are scarce. Moreover, the underlying mechanisms of change and their persistence remain unexplored. Here we show that, over the past 1.36 million years, wet winters in the northcentral Mediterranean tend to occur with high contrasts in local, seasonal insolation and a vigorous African summer monsoon. Our proxy time series from Lake Ohrid on the Balkan Peninsula, together with a 784,000-year transient climate model hindcast, suggest that increased sea surface temperatures amplify local cyclone development and refuel North Atlantic low-pressure systems that enter the Mediterranean during phases of low continental ice volume and high concentrations of atmospheric greenhouse gases. A comparison with modern reanalysis data shows that current drivers of the amount of rainfall in the Mediterranean share some similarities to those that drive the reconstructed increases in precipitation. Our data cover multiple insolation maxima and are therefore an important benchmark for testing climate model performance

Transcriptomic Analysis Comparing Tumor-Associated Neutrophils with Granulocytic Myeloid-Derived Suppressor Cells and Normal Neutrophils

The role of myeloid cells in supporting cancer growth is well established. Most work has focused on myeloid-derived suppressor cells (MDSC) that accumulate in tumor-bearing animals, but tumor-associated neutrophils (TAN) are also known to be capable of augmenting tumor growth. However, little is known about their evolution, phenotype, and relationship to naïve neutrophils (NN) and to the granulocytic fraction of MDSC (G-MDSC)

Lunatic Fringe Deficiency Cooperates with the Met/Caveolin Gene Amplicon to Induce Basal-like Breast Cancer

Basal-like breast cancers (BLBC) express a luminal progenitor gene signature. Notch receptor signaling promotes luminal cell fate specification in the mammary gland, while suppressing stem cell self-renewal. Here we show that deletion of Lfng, a sugar transferase that prevents Notch activation by Jagged ligands, enhances stem/progenitor cell proliferation. Mammary-specific deletion of Lfng induces basal-like and claudin-low tumors with accumulation of Notch intracellular domain fragments, increased expression of proliferation-associated Notch targets, amplification of the Met/Caveolin locus, and elevated Met and Igf-1R signaling. Human BL breast tumors, commonly associated with JAGGED expression, elevated MET signaling, and CAVEOLIN accumulation, express low levels of LFNG. Thus, reduced LFNG expression facilitates JAG/NOTCH luminal progenitor signaling and cooperates with MET/CAVEOLIN basal-type signaling to promote BLBC
