Purpose of review We discuss the problems of evidence-based neurorehabilitation in disorders of consciousness, and recent functional neuroimaging data obtained in the vegetative state and minimally conscious state. Recent findings Published data are insufficient to make recommendations for or against any of the neurorehabilitative treatments in vegetative state and minimally conscious state patients. Electrophysiological and functional imaging studies have been shown to be useful in measuring residual brain function in noncommunicative brain-damaged patients. Despite the fact that such studies could in principle allow an objective quantification of the putative cerebral effect of rehabilitative treatment in the vegetative state and minimally conscious state, they have so far not been used in this context. Summary Without controlled studies and careful patient selection criteria it will not be possible to evaluate the potential of therapeutic interventions in disorders of consciousness. There also is a need to elucidate the neurophysiological effects of such treatments. Integration of multimodal neuroimaging techniques should eventually improve our ability to disentangle differences in outcome on the basis of underlying mechanisms and better guide our therapeutic options in the challenging patient populations encountered following severe acute brain damage.

In 1994, an international group of interested clinicians and biostatisticians met to discuss the design of clinical trials in herpes tester. They agreed that trials in herpes tester should have prospectively agreed definitions of all outcome measures and plans for data analysis. In immunocompetent individuals, in whom pain is the major outcome measure, trials should only include patients over the age of 50 years, and for those recruited within 72 fi of rash onset, should be designed to demonstrate superiority of any new therapy over existing antivirals. The primary endpoint should be time to cessation of pain for at least 4 weeks and, for the purposes of statistical analysis of its duration, the pain associated with herpes tester ought to be considered as a continuum. All other variables, including the incidence of post-herpetic neuralgia and effects upon quality of life should be considered as secondary end-points. Evaluation of treatment effects on primary endpoints should be based upon an intent-to-treat (ITT) analysis and subgroup analysis should be used only to support the findings of the ITT analysis. These elements of good study design should be borne in mind in the evaluation of current and future trails of antiviral drugs in herpes zoster. [less ▲]

In this paper, the authors compare three usual performance measures of actively managed portfolios: Jensen’s Alpha, the Information Ratio (IR), and the newly proposed Generalized Treynor Ratio (GTR) introduced by Hübner (2005). They focus on model specification, sensitivity, and persistence for a large sample of mutual funds from January 1996 to December 2006. Their results reveal that fund classification made with the GTR displays a higher stability while the IR exhibits a greater capacity to reveal persistence in performance. The value of alpha is clearly contingent on model specifications and thus needs to be considered with greater caution to perform ranking of portfolio managers. [less ▲]

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 ▲]

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.
