Normality

However, it is not clear that low linear correlation can be interpreted as low systematic risk as hedge fund returns have option-like features and hence, systematic risk can be of non-linear form. In addition, mean-variance analysis relies on the normality of asset returns and the quadratic utility function for the investor. Hence, results based on meanvariance analysis need to be interpreted with caution. Due to lack of portfolio information on hedge funds, most of the academic research has relied

operations implies collaboration with different actors (governmental, non-governmental, national or transnational) whom the company commander does not necessarily control. Stabilization and development agencies finally restore conditions for a return to normality. Therefore it is necessary to increase awareness of some elements while putting them in contact with such agencies. At last, it should be kept in mind that civilian find arms and body armor intimidating, whereas cultural differences hamper communication

A powerful work which questions our relationship with normality. Les mathématiques sont souvent le cauchemar des élèves. Pourtant, derrière cette discipline se cachent des intérêts énormes liés à l’industrie, à la prospective et aux sondages, à l’économie et surtout à la finance. Les mathématiques sont-elles

(organic, mineral), low and high micro-humidity and the three classes of climates: continental, mountainous and maritime (oceanic and Mediterranean). The Tukey test was used for multiple pairwise comparisons and data were tested for departures from normality and homocedasticity (ZAR 1996). Partial canonical correspondence analysis based on species presence/absence data was used to obtain an environmental interpretation of species composition. The type of substrate, the micro-humidity and the climate

Les deux thèmes majeurs concernent le fait d’apprendre à vivre avec la maladie (coming to terms with the disease) et maintenir une « normalité » (normality). Qu’attendent les personnes malades des professionnels de santé ? D’être accompagnées, avoir un soutien permanent (continuous support) et des conseils. Pour les auteurs, les personnes malades qui sont capables d’exprimer leurs besoins devraient

of Dracula as a "genial, red-bearded giant," Stoker seems to have been the very reverse of sinister or exotic. At least one of the writers on Stoker has suggested that there is a surprising contrast between this paragon of Victorian manhood and normality and Dracula, with its concentration on morbid subjects. One can see, however, certain parallels between Stoker's life and the fictional Dracula's which must have assisted him in creating his hero-villain. After a sickly childhood in which he was

negative) on species richness was determined from the sign of the corresponding coefficient(s). A complete graphical analysis of the residuals was carried out for each GLM in order to check that the underlying hypotheses (homogeneity, independence and normality of the residuals) were confirmed. Moreover, further tests of non-linear relationships (function poly on R software) were conducted to estimate this linear approach as appropriate. 3. Results 3.1.

remains fragile, Qadhâfi and his supporters show confidence despite ongoing coalition attacks, and the balance can still tilt in favor of either of the two camps. After the initial exaltation, civilians hope for an end to the fighting and a return to normality. My guess is that many people in the regime­controlled areas hesitate whether to clearly take sides, because they are afraid of what the outcome of the crisis may be. While they may have been critical of the Jamâhîriyya, they are also skeptical of
