Expert judgment versus public opinion - evidence from the Eurovision Song Contest
For centuries, there have been discussions as to whether only experts can judge the quality of cultural output, or whether the taste of the public also has merit. This paper tries to resolve that question empirically, using national finals of the Eurovision Song Contest. We show that experts are better judges of quality: the outcome of finals judged by experts is less sensitive to factors unrelated to quality than the outcome of finals judged by public opinion. Yet, experts are not perfect: their judgment does still depend on such factors. This is also the case in the European finals of the contest.

Do entry barriers, perceived by SMEs, affect real antry? Some evidence from the Netherlands
The objective of this paper is to analyse the relationship between perceived entry barriers and real entry. Real entry rates are interpreted as an indicator for the dynamics in an industry. The major hypothesis of this paper is that important entry barriers restrict new entry. Real entry rates are provided by a starter ratio for different industrial sectors and provinces in the Netherlands.
Predicting Patchy Particle Crystals: Variable Box Shape Simulations and Evolutionary Algorithms
We consider several patchy particle models that have been proposed in
literature and we investigate their candidate crystal structures in a
systematic way. We compare two different algorithms for predicting crystal
structures: (i) an approach based on Monte Carlo simulations in the
isobaric-isothermal ensemble and (ii) an optimization technique based on ideas
of evolutionary algorithms. We show that the two methods are equally successful
and provide consistent results on crystalline phases of patchy particle
systems.Comment: 25 pages, 4 figures, 3 tables Journal of Chemical Physics, accepte
Perceptions regarding strategic and structural entry barriers
This article uses factor analysis to identify the underlying dimensions of strategic and structural entry barriers. We find that, in the perception of firms, both types of barriers are important and that the effectiveness of strategic barriers depends on attributes of the market structure. Based on the seven generic factors, a conjoint analysis is carried out to identify the most important factors perceived by firms. The conjoint analysis shows that in particular the barriers rooted in three underlying dimensions require attention of market authorities as they may prevent new entrants from entry: capital, access to distribution channels and strategic action. Remarkably, government rules and regulations, product differentiation, research and development (R&D) and advertising constitute minor entry problems according to firm
Long noncoding RNA H19X is a key mediator of TGF-beta-driven fibrosis
TGFβ is a master regulator of fibrosis, driving the differentiation of fibroblasts into apoptosis resistant myofibroblasts and sustaining the production of extracellular matrix (ECM) components. Here, we identify the nuclear lncRNA H19X as a master regulator of TGFβ-driven tissue fibrosis. H19X was consistently upregulated in a wide variety of human fibrotic tissues and diseases and was strongly induced by TGFβ, particularly in fibroblasts and fibroblast-related cells. Functional experiments following H19X silencing revealed that H19X is an obligatory factor for the TGFβ-induced ECM synthesis as well as differentiation and survival of ECM-producing myofibroblasts. We showed that H19X regulates DDIT4L gene expression, specifically interacting with a region upstream of DDIT4L gene and changing the chromatin accessibility of a DDIT4L enhancer. These events resulted in transcriptional repression of DDIT4L and, in turn, in increased collagen expression and fibrosis. Our results shed light on key effectors of the TGFβ-induced ECM remodeling and fibrosis
