The first world wide symposium on the topic of gender-specific medicine provided the latest research on differences in sex and/or gender in medicine and medical care. The presentations ranged beyond the topic of reproduction to encompass the entire human organism. This report critically reviews three issues that emerged during the Conference: gender mainstreaming, the concept of sex/gender differences and the issue of men's health. It suggests that the interdisciplinary concept of gender-specific medicine has to be mirrored by the integration of social and cultural studies into medical research and practice.

The Bossons glacier protects Europe's summit from erosion

2013

13 pages; International audience; The contrasting efficiency of erosion beneath cold glacier ice, beneath temperate glacier ice, and on ice-free mountain slopes is one of the key parameters in the development of relief during glacial periods. Detrital geochronology has been applied to the subglacial streams of the north face of the Mont-Blanc massif in order to estimate the efficiency of erosional processes there. Lithologically this area is composed of granite intruded at ~303 Ma within an older polymetamorphic complex. We use macroscopic features (on ~10,000 clasts) and U-Pb dating of zircon (~500 grains) to establish the provenance of the sediment transported by the glacier and its subgl…

Two-dimensional numerical modeling of fracturing and shear band development in glacier fronts

2014

In this contribution we present a two-dimensional numerical model of a deforming glacier front. The model is based on a hybrid lattice spring network approach where particles in the model can deform in a volume conservative visco-elastic manner but at the same time they can be compressed elastically and fracture by discrete failure. We restrict ourselves to a simple setting where the glacier sits on a frictionless slope that dips with 5–10°, the ice block is fixed on one side and has a free surface on the other. The glacier varies in viscosity and can flow at the base, whereas it is brittle at the top. Results show that the head of the glacier is unstable. Failure happens as a combination o…

Migrating neuroblasts of the rostral migratory stream are putative targets for the action of nitric oxide

2007

It has been demonstrated that the gaseous messenger nitric oxide influences cell proliferation and cell migration, and therefore affects adult neurogenesis in mammals. Here, we investigated the putative targets for this action in the rostral migratory stream of the rat. We used immunocytochemical detection of the beta1 subunit of the enzyme soluble guanylyl cyclase, which can be activated by nitric oxide. Our results under light and electron microscopy demonstrated that the migrating neuroblasts (type A cells) were beta1-immunopositive. The astrocytes (type B cells), immature precursors (type C cells) and ependymal cells (type E cells) were beta1-immunonegative. The neurochemical characteri…

Globalization Is Dead: Long Live the Globalization!?

2018

Globalization was the mainstream paradigm in the last 70 years, long enough to create and explain prosperity and welfare in a connected world. Recently, there are many signs that we are reaching a turning point. From jobs, wages, and unemployment to immigrants and Brexit, all the key debates emphasize that the world is preparing for a new kind of globalization which will be less about countries and multinationals and more about people. There is no doubt that old globalization had winners and losers, but more than ever, the voice of the people who reject globalization was heard in 2016, specifically in the UK and USA. The world will have to deal with new institutions, and technologies and wi…

Quantitative Bestimmung des Gallenr�ckflusses in Blut und Leberlymphe von Ratten bei beginnender Gallenstauung

1970

1. Mit dem Ziel, die Anteile des bei einer Gallenstauung auftretenden Gallenruckflusses in Blut und Lymphe quantitativ zu erfassen, wurde ein Verfahren zur Gewinnung reiner Leberlymphe bei Ratten entwickelt. 2. Mit Hilfe dieser Methode konnte am Versuchstier mit normaler Korpertemperatur aus Messungen der Lymphstromstarke und des Eiweisgehaltes der Leberlymphe vor und wahrend einer Gallenstauung auf einen Ruckflus der fortlaufenden produzierten Galle in die Leberlymphe von ca. 7–10% geschlossen werden. 3. In Ruckflusversuchen an unterkuhlten Ratten mit Ringerlosung, die Evansblue enthielt, ergaben Analysen von Blut und Leberlymphe einen Anteil des Ruckflusses in diese Lymphe von ca. 13%.

Alliance formation as growth opportunity for non-publicly traded companies: a value-added service provided by private equity investors

2016

We analyze the role of Private Equity firms (PE-Firms) as a governance mechanism, focusing on their role as social intermediaries, helping their portfolio companies to form alliances and thereby spurring entrepreneurial growth. Alliances as long term inter-firm cooperations are considered to be a main source of firm-innovation. External growth via alliances is especially important for small to medium sized companies (SME) – largely dominant in Europe (up to 99%)–, because their internal resources are limited. Since a few years, these facts lead governments to undertake actions aimed to create environments that boost inter-firm linkages and entrepreneurial clusters. In European countries, su…

Private Equity Investors as Matchmakers: Alliance Formation between PE-backed firms

2016

International audience; Alliances as long term inter-firm cooperation are seen as an important factor of economic growth. They are particularly important for small to medium sized companies whose internal resources are scarce. This article analyses the role of Private Equity Firms that constitute a major source of financing for non-publicly traded small to medium sized companies, in the formation of alliances for their portfolio companies. While previous studies analyse the question in the light of mainstream theories, we rely on the dual theory of the firm, combining the contractual/mainstream view and the knowledge-based view. Contrary to the current literature, our study does not rely on…

How does public spending affect technical efficiency? Some evidence from 15 European countries

2020

The relationship between government size and economic growth has been widely debated. Revisiting the subject from a distinct angle with respect to the mainstream approach, we provide an empirical analysis of the impact of government size on technical efficiency. The aim of this paper is to estimate the impact of public sector's size and of public expenditure components on 15 European countries’ technical efficiency from 1996 to 2014 by using a True Random Effect model. Using the total public expenditure as a proxy for the government size we estimate simultaneously national optimal production function and technical efficiency by controlling for income distribution and institutional quality. …

FROM SEEKERS TO ACTIVISTS

2009

Media culture is a firm part of youth cultures today. Media can also be seen as one empowering technology in the information society alongside traditional school and government. What kind of civic identities are young people constructing in contemporary media culture? This article discusses media-saturated youth and audience agency, drawing on Dahlgren's ideas of civic culture. Relying on empirical data from two case studies in Finland, we will introduce a typology of civic identities, which the young construct as members of the public in relation to media. Our first case study is a youth civic website called Vaikuttamo.net and the second is the Youth Voice Editorial Board, which consists o…
