From the analysis of (closing value) stock market index like the Dow Jones Industrial average and the S&P500 it is possible to observe the precursor of a so-called crash. This is shown on the Oct. 1987 and Oct. 1997 cases. The data analysis indicates that the index divergence has followed twice a "universal"; behavior, i.e. a logarithmic dependence, superposed on a well defined oscillation pattern. The prediction of the crash date is remarkable and can be done two months in advance. In the spirit of phase transition phenomena, the economic index is said to be analogous to a signal signature found in a two dimensional fluid of vortices. [less ▲]

While most past studies have emphasized the relationships between specific forest stands and edaphic factors, recent observations in Central African moist forests suggested that an increase of slash-and-burn agriculture since 3000–2000 BP (Before Present) could be the main driver of the persistence of light-demanding tree species. In order to examine anthropogenic factors in the persistence of such populations, our study focused on Pericopsis elata, an endangered clustered timber species. We used a multidisciplinary approach comprised of botanical, anthracological and archaeobotanical investigations to compare P. elata patches with surrounding stands of mixed forest vegetation (“out-zones”). Charcoal samples were found in both zones, but were significantly more abundant in the soils of patches. Eleven groups of taxa were identified from the charcoals, most of them also present in the current vegetation. Potsherds were detected only inside P. elata patches and at different soil depths, suggesting a long human presence from at least 2150 to 195 BP, as revealed by our charcoal radiocarbon dating. We conclude that current P. elata patches most likely result from shifting cultivation that occurred ca. two centuries ago. The implications of our findings for the dynamics and management of light-demanding tree species are discussed. [less ▲]

Risk assessments are mostly carried out based on available data, which do not reflect all data theoretically required by experts to answer them. This study aimed at developing a methodology to assess data availability, accessibility and format, based on a scoring system and focusing on two diseases: Venezuelan equine encephalomyelitis (VEE), still exotic to Europe, and alveolar echinococcosis, caused by Echinococcus multilocularis (EM), endemic in several Member States (MSs). After reviewing 36 opinions of the EFSA-AHAW Panel on risk assessment of animal health questions, a generic list of needed data was elaborated. The methodology consisted, first, in implementing a direct and an indirect survey to collect the data needed for both case studies: the direct survey consisted in a questionnaire sent to contact points of three European MSs (Belgium, France and the Netherlands), and the organization of a workshop gathering experts on both diseases. The indirect survey, focusing on the three MSs involved in the direct survey plus Spain, relied on web searches. Secondly, a scoring system with reference to data availability, accessibility and format was elaborated, to, finally, compare both diseases and data between MSs. The accessibility of data was generally related to their availability. Web searches resulted in more data available for VEE compared to EM, despite its current exotic status in the European Union. Hypertext markup language and portable document files were the main formats of available data. Data availability, accessibility and format should be improved for research scientists/assessors. The format of data plays a key role in the feasibility and rapidness of data management and analysis, through a prompt compilation, combination and aggregation in working databases. Harmonization of data collection process is encouraged, according to standardized procedures, to provide useful and reliable data, both at the national and the international levels for both animal and human health; it would allow assessing data gaps through comparative studies. The present methodology is a good way of assessing the relevance of data for risk assessment, as it allows integrating the uncertainty linked to the quality of data used. Such an approach could be described as transparent and traceable and should be performed systematically. [less ▲]

Although no one seriously disputes the binding nature of human rights standards on the activity of the International Criminal Court (“the ICC” or “the Court”), the precise boundaries of this human rights constraint still lack clarity. In particular, there is no consensus on the basis for such an obligation, especially given the fact that the Court is not party to the relevant international and regional instruments. It is argued that the lack of clarity on the exact foundations for the binding nature of human rights standards towards the Court presents a real threat to the development of international criminal jurisprudence. This is because the legal grounds on which the ICC is bound to respect individual rights are also determinative of the very content of the resulting obligations. This paper aims to contribute to remedy this lacuna by listing and critically assessing the theoretical legal constructions on the basis of which human rights law is commonly said to enter the framework of the Court.

In a Web 2.0 context, negative user-generated content (UGC) that damages the brand reputation can be easily produced and quickly spread. There is a lack of literature on how to measure the value destruction, known as doppelgänger brand image (DBI). The authors define DBI as the appearance, or reinforcement, of negative associations at the brand reputation level. Brand reputation is the collective brand image that is shared by multiple stakeholders. Using brand concept mapping (BCM) on two corporate brands, this study shows the effect of exposure to negative UGC on the brand image perception and measures the impact of this exposure on DBI. The authors use a two*two between-subjects design with 280 consumers in order to study the effects of the type of media and source credibility, brand experience and Internet experience on the DBI. The results suggest that, the negative UGC will cause an increase in the frequency of mentions of negative associations. At the reputation level, if the brand already has a DBI, an exposure to negative UGC will reinforce it. However, if the brand reputation is mostly positive, a single exposure to negative UGC will not create a DBI. The results also confirm the effect of source credibility and type of media on the likelihood of DBI. The experience with the brand and with Internet will reduce the risk of DBI. [less ▲]

Which theoretical categories can we use to talk about an artist’s drawing? The quality of the line, the specific rhythm, the relationship between line and color, the degree of realism or the aesthetic influence of past masters: these are not easy to describe in an original way. The difficulties encountered in the traditional field of the fine arts also present themselves when considering comics because the drawing is specific and implicates a different temporality. The artists themselves regret the lack of a real aesthetic approach to their works, but we cannot simply transpose the usual discourse to the study of comics: as a young medium, this art form deserves relevant categories of analysis. My research will investigate what Aesthetics, as formal approach, could add to comics studies. I propose to read Joan Sfar’s auto-biographical notebooks published by L’association between 2002 and 2005 – in particular: Harmonica, Ukulélé, Parapluie, Piano, Caravan. These notebooks contain precious insight into his work method and his drawing. I would like to highlight several recurring themes. Sfar first criticizes the “academic drawing” he learned at school as being too “realist,” “anatomical,” and devoid of life. He explains that it took him a long time to depart from this kind of drawing. By contrast, he heartily advocates drawing directly from the perception of movement, situation, and expression, implying rapid and freehand drawing. In this context, Sfar refers to the famous illustrator Quentin Blake, who describes his career path, accompanied by relevant drawings, in La vie de la page (1995). I propose to compare Joan Sfar’s ideas on drawing with this principal influence on his work. Finally, the theory of color and light shows – in another way – the importance of the accidental and the uncalculated in his art. My arguments will be supported by various examples of Sfar’s work.

Recent events such as natural catastrophes or terrorism attacks have highlighted the necessity to ensure the structural integrity of buildings under an exceptional event. According to Eurocodes and some other national design codes, the structural integrity of civil engineering structures should be guaranteed through appropriate measures and one way to guarantee it is to ensure an appropriate robustness of the structure, which may be defined as the ability of a structure to remain globally stable in case of exceptional event leading to local damages. However, although global design approaches are provided in modern codes and standards, no easy-to-apply practical guidelines are provided. The present paper reflects recent researches realised at the University of Liege with the scope of proposing such practical guidelines for the activation of alternative load path in the structure, design strategy generally leading to the most economical solutions.

Relationship coefficients are particularly useful to improve genetic management of endangered populations. These coefficients are traditionally based on pedigree data. In case of incomplete or missing pedigree, they are replaced by coefficients calculated from molecular data when this information is available. However, genotyping a complete population for a sufficient number of markers can be impossible. The main objective of this study was therefore to develop a new method to estimate relationship by combining molecular with pedigree data. It will be useful for specific situations, where neither pedigree nor molecular data are complete. In a companion paper, the compatible coefficients were determined. In this study, based on simulations of pedigree and marker data, the method to combine the selected coefficients was determined. Various parameters were taken into account in the model: number and quality of the marker (e.g. marker informativeness), mutation rate, quality of the pedigree (e.g. generation-equivalents), … The combined estimator has several advantages. Especially, negative relationship values obtained in literature with molecular-based estimators in case of small inbred populations can be avoided. In conclusion, this combined estimator was originally developed for the management of an endangered horse population. It should also be a promising alternative to traditionally used estimators, e.g. for the management of small and/or rare breeds; especially in case of inbred populations, with both incomplete pedigree and partial molecular information.
