The European Commission recently put forward a proposal for a regulation to amend and strengthen the 2009 version of the EU's rules on the regulation of credit rating agencies ("CRA3"). Among other things, Art. 35a of the draft proposal introduces strict liability for rating agencies. This liability proposal is at odds with the aim to strengthen competition in the rating sector and could have a chilling effect on capital markets. The paper analyses existing rules on civil liability of rating agencies under different legal systems. Subsequently, the provision under Art. 35a of the Draft Proposal is examinded more closely. Suggestions on possible improvemts of the proposal are made.

The Center of Excellence SAFE – “Sustainable Architecture for Finance in Europe” – is a cooperation of the Center for Financial Studies and Goethe University Frankfurt. It is funded by the LOEWE initiative of the State of Hessen (Landes-Offensive zur Entwicklung wissenschaftlich-ökonomischer Exzellenz). SAFE brings together more than 40 professors and just as many junior researchers who are all dedicated to conducting research in support of a sustainable financial architecture. The Center has two main pillars: excellent research on all important topics related to finance; and policy advice, including the dissemination of relevant research findings to European decision makers from the realms of politics, regulation and administration.
In order to promote a fruitful exchange with interested parties from politics, academia, business and the media, SAFE issues a newsletter on a quarterly basis. This aims to provide an overview of the Center‘s ongoing research and policy activities. The SAFE Newsletter succeeds the House of Finance Newsletter, which was published between 2009 and 2012.
SAFE is based at Goethe University’s House of Finance however extends beyond by drawing on scholars from other parts of Goethe University as well as from fellow research institutions. The Center builds on the reputation of the House of Finance institutions, serving as an interdisciplinary think tank on the issue of finance.
Debt-induced crises, including the subprime, are usually attributed exclusively to supply-side factors. We uncover an additional factor contributing to debt culture, namely social influences emanating from the perceived average income of peers. Using unique information from a representative household survey of the Dutch population that circumvents the need to define the social circle, we consider collateralized, consumer, and informal loans. We find robust social effects on borrowing – especially among those who consider themselves poorer than their peers – and on indebtedness, suggesting a link to financial distress. We check the robustness of our results using several approaches to rule out spurious associations and handle correlated effects.
Planar cell polarity (PCP)–the coordinated polarisation of a whole field of cells within the plane of a tissue–relies on the interaction of three modules: a global module that couples individual cellular polarity to the tissue axis, a local module that aligns the axis of polarisation of neighbouring cells, and a readout module that directs the correct outgrowth of PCP-regulated structures such as hairs and bristles. While much is known about the molecular components that are required for PCP, the functional details of–and interactions between–the modules remain unclear. In this work, we perform a mathematical and computational analysis of two previously proposed computational models of the local module (Amonlirdviman et al., Science, 307, 2005; Le Garrec et al., Dev. Dyn., 235, 2006). Both models can reproduce wild-type and mutant phenotypes of PCP observed in the Drosophila wing under the assumption that a tissue-wide polarity cue from the global module persists throughout the development of PCP. We demonstrate that both models can also generate tissue-level PCP when provided with only a transient initial polarity cue. However, in these models such transient cues are not sufficient to ensure robustness of the resulting cellular polarisation.
Since the 1980s, advances in wastewater treatment technology have led to considerably improved surface water quality in the urban areas of many high income countries. However, trace concentrations of organic wastewater-associated contaminants may still pose a key environmental hazard impairing the ecological quality of surface waters. To identify key impact factors, we analyzed the effects of a wide range of anthropogenic and environmental variables on the aquatic macroinvertebrate community. We assessed ecological water quality at 26 sampling sites in four urban German lowland river systems with a 0–100% load of state-of-the-art biological activated sludge treated wastewater. The chemical analysis suite comprised 12 organic contaminants (five phosphor organic flame retardants, two musk fragrances, bisphenol A, nonylphenol, octylphenol, diethyltoluamide, terbutryn), 16 polycyclic aromatic hydrocarbons, and 12 heavy metals. Non-metric multidimensional scaling identified organic contaminants that are mainly wastewater-associated (i.e., phosphor organic flame retardants, musk fragrances, and diethyltoluamide) as a major impact variable on macroinvertebrate species composition. The structural degradation of streams was also identified as a significant factor. Multiple linear regression models revealed a significant impact of organic contaminants on invertebrate populations, in particular on Ephemeroptera, Plecoptera, and Trichoptera species. Spearman rank correlation analyses confirmed wastewater-associated organic contaminants as the most significant variable negatively impacting the biodiversity of sensitive macroinvertebrate species. In addition to increased aquatic pollution with organic contaminants, a greater wastewater fraction was accompanied by a slight decrease in oxygen concentration and an increase in salinity. This study highlights the importance of reducing the wastewater-associated impact on surface waters. For aquatic ecosystems in urban areas this would lead to: (i) improvement of the ecological integrity, (ii) reduction of biodiversity loss, and (iii) faster achievement of objectives of legislative requirements, e.g., the European Water Framework Directive.
This study indicates that embryonic stem cells [ESCs] cultured with retinoic acid and activin A significantly upregulate the miRNA let-7e. This specific miRNA modulates the Wnt pathway and the expression of early nephrogenic markers under these differentiation conditions. The differentiation markers WT1, Pax2 and Wnt4 were downregulated when miRNA let-7e was silenced, thus indicating the role of miRNA let-7e in the differentiation process. PKCβ, GSK3β phosphorylation (GSK3βP) and β-catenin expression was reduced in differentiated cells and reversed by miRNA let-7e silencing. Addition of a PKCβ inhibitor to the miRNA let-7e silenced cells abolished let-7e-derived effects in differentiation markers, and reversed the increase in GSK3βP and β-catenin, thus indicating that miRNA let-7e is involved in differentiation via the modulation of GSK3β phosphorylation and β-catenin production.
Die Dissertation stellt das Machtgeflecht in der Islamischen Stadt Marawi City (Mindanao, Philippinen) dar, in die die dortigen Gender-Debatten involviert sind. In einer Umgebung, die als Konsequenz des Mindanao Konfliktes als “no war, no peace”-Umgebung definiert werden kann, gibt es drei Hauptdarsteller: die nationale Regierung des mehrheitlich christlichen Staates der Philippinen (GRP), die Autonome Regierung im Muslimischen Mindanao (ARMM), zu der auch Marawi City zählt, und die islamische Rebellengruppe Moro Islamic Liberation Front (MILF), die einen islamischen (unter-)Staat fordert. Die GRP unterstützt Re-Islamisierungs- und Re-Traditionalisierungsbewegungen in der ARMM, um die Opposition zur MILF zu stärken. Die Konsequenz ist jedoch keine Kollaboration zwischen der GRP und der ARMM. Stattdessen nutzen Politiker ihre Privilegien aus, um ihren eigenen Absichten zu folgen. Sei dies, um politische Gegner auszuspielen oder das traditionelle Sultanatssystem zu fördern. Für Gender-Debatten gibt es in diesem Kontext der ungelösten nationalen Frage kaum Spielraum außerhalb einer Islamischen Narrative; dies bedeutet jedoch nicht, dass Gender nicht debattiert wird, sondern, dass die Debatten inner-Islamisch sind, hauptsächlich zwischen Repräsentanten des traditionell synkretistischen Islam und Vertretern Islamischer Revitalisierungsbewegungen. Speziell erstere erscheinen sehr einflussreich bezüglich Gender Strategien in der Region. Dies ist nur teilweise auf die Unterstützung der nationalen Regierung zurückzuführen, sondern ist vor allem eine Frage von Identität. Diese wiederum wird nicht vorranging über Religion, sondern nach ethnischen Maßstäben und im Speziellen im Rahmen von Clanstrukturen definiert.
