The cyclotron laboratory and the RFQ accelerator in Bern

Two proton accelerators have been recently put in operation in Bern: an 18 MeV cyclotron and a 2 MeV RFQ linac. The commercial IBA 18/18 cyclotron, equipped with a specifically conceived 6 m long external beam line ending in a separate bunker, will provide beams for routine 18-F and other PET radioisotope production as well as for novel detector, radiation biophysics, radioprotection, radiochemistry and radiopharmacy developments. The accelerator is embedded into a complex building hosting two physics laboratories and four Good Manufacturing Practice (GMP) laboratories. This project is the result of a successful collaboration between the Inselspital, the University of Bern and private investors, aiming at the constitution of a combined medical and research centre able to provide the most cutting-edge technologies in medical imaging and cancer radiation therapy. The cyclotron is complemented by the RFQ with the primary goals of elemental analysis via Particle Induced Gamma Emission (PIGE), and the detection of potentially dangerous materials with high nitrogen content using the Gamma-Resonant Nuclear Absorption (GRNA) technique. In this context, beam instrumentation devices have been developed, in particular an innovative beam profile monitor based on doped silica fibres and a setup for emittance measurements using the pepper-pot technique. On this basis, the establishment of a proton therapy centre on the campus of the Inselspital is in the phase of advanced study.

How political economies affect immigrants' socio-economic incorporation. A comparative analysis of immigrants’ poverty risks across advanced industrialised countries

Immigration and the resulting increasing ethnic diversity have become an important characteristic of advanced industrialised countries. At the same time, the majority of the countries in question are confronted with structural transformation such as deindustrialisation and changes in family structures as well as economic downturn, which limit the capacities of nation-states in addressing rising inequality and supporting those individuals at the margins of the society. This paper addresses both issues, immigration and inequality, by focusing on immigrants’ socio-economic incorporation into the receiving societies of advanced industrialised countries. The aim of this paper is to explain cross-national variation in immigrants’ poverty risks. Drawing on the political economy as well as the migration literature, the paper develops a theoretical framework that considers how the impact of the national labour market and welfare system on immigrants’ poverty risks is moderated by the integration policies, which regulate immigrants’ access to the labour market and social programs (or immigrants’ economic and social rights). The empirical analysis draws on income surveys as well as a newly collected data set on economic and social rights of immigrants in 19 advanced industrialised countries, including European countries as well as Australia, and North America, for the year 2007. As the results from multilevel analysis show, integration policies concerning immigrants’ access to the labour market and social programs can partly explain cross-national variations in immigrants’ poverty risks. In line with the hypothesis, stricter labour market regulations such as minimum wage setting reduce immigrants’ poverty risks stronger in countries where they are granted easier access to the labour market. However, concerning the impact of more generous social programs the reductive poverty effect is stronger in countries with less inclusive access of immigrants to social programs. The paper concludes by discussing possible explanations for this puzzling finding.

Biographien und Netzwerke im Kaffeehandel zwischen Deutschland und Zentralamerika, 1920-1959

Kaffee ist nicht nur ein beliebtes Getränk, sondern vernetzte auch unterschiedliche Welten: Der Kaffeehandel band Hamburg und Bremen in transnationale Netzwerke ein, die sich zwischen Europa und Lateinamerika erstreckten. Zentralamerika war für den globalen Kaffeehandel wichtig, weil die Region als erste die „nasse“ Form der Aufbereitung einführte. Die hohe Qualität dieser „gewaschenen“ Kaffees machte sie auf dem Weltmarkt begehrt. Deutsche Einwanderer prägten die Handelsverbindungen zwischen den zentralamerikanischen Kaffee-Anbauregionen und den norddeutschen Hafenstädten: Sie gründeten Exportfirmen, erwarben Kaffeeplantagen und beteiligten sich an der Vorfinanzierung der Ernten. Christiane Berth analysiert Biografien und Netzwerke deutscher Kaffee-Akteure in Guatemala, Costa Rica und Chiapas. Dabei zeigt sie, wie deren Handelsnetzwerke durch wirtschaftliche Krisen und neue außenpolitische Konstellationen brüchig wurden, im Nationalsozialismus unter Druck gerieten und während des Zweiten Weltkrieges zerbrachen. Trotzdem blieben auch in der Nachkriegszeit Handelsbeziehungen zwischen Nationalstaaten, Netzwerke in der Kaffeebranche und Biografien der Kaffee-Akteure eng miteinander verknüpft.

Pulmonary lymphangioleiomyomatosis: analysis of disease manifestation by region-based quantification of lung parenchyma

PURPOSE Lymphangioleiomyomatosis (LAM) is characterized by proliferation of smooth muscle tissue that causes bronchial obstruction and secondary cystic destruction of lung parenchyma. The aim of this study was to evaluate the typical distribution of cystic defects in LAM with quantitative volumetric chest computed tomography (CT). MATERIALS AND METHODS CT examinations of 20 patients with confirmed LAM were evaluated with region-based quantification of lung parenchyma. Additionally, 10 consecutive patients were identified who had recently undergone CT imaging of the lung at our institution, in which no pathologies of the lung were found, to serve as a control group. Each lung was divided into three regions (upper, middle and lower thirds) with identical number of slices. In addition, we defined a "peel" and "core" of the lung comprising the 2 cm subpleural space and the remaining inner lung area. Computerized detection of lung volume and relative emphysema was performed with the PULMO 3D software (v3.42, Fraunhofer MEVIS, Bremen, Germany). This software package enables the quantification of emphysematous lung parenchyma by calculating the pixel index, which is defined as the ratio of lung voxels with a density <-950HU to the total number of voxels in the lung. RESULTS Cystic changes accounted for 0.1-39.1% of the total lung volume in patients with LAM. Disease manifestation in the central lung was significantly higher than in peripheral areas (peel median: 15.1%, core median: 20.5%; p=0.001). Lower thirds of lung parenchyma showed significantly less cystic changes than upper and middle lung areas combined (lower third: median 13.4, upper and middle thirds: median 19.0, p=0.001). CONCLUSION The distribution of cystic lesions in LAM is significantly more pronounced in the central lung compared to peripheral areas. There is a significant predominance of cystic changes in apical and intermediate lung zones compared to the lung bases.

Managing social policy under federalism: The challenges of hybrid funding and program delivery

This paper discusses generally the question of the level of government that should be used to administer different social policies. The chapter focuses on the Medicaid program, looking at recent state-level changes in health insurance for the poor and long-term care policy. Particular attention will be paid to the question of how states have used their new freedoms to outsource public insurance to the private sector and on the consequent differences in outcomes across states. Notably, this paper will be drawn from my forthcoming book “The American Myth of Markets in Social Policy” (Palgrave, MacMillan, November, 2015).
