Jeux de mémoires, jeux de miroirs : appropriations historiques et justifications langagières des langues amazighe, arabe et tunisienne
No full text"Au printemps 2018, au Centre d’arts vivants Safia Farhat, à Radès, dans la banlieue sud de Tunis,
s’est tenue une exposition collective nommée Histoire(s). L’artiste plasticienne Aicha Filali y a planté
un "arbre-histoire" (Figure 1). Comme son nom l’indique, il s’agit d’une sculpture composée d’un
tronc et de branches sur lesquels des rétroviseurs sont disposés. Ils sont de formes différentes : ronde,
ovale, carrée, rectangulaire ; ils ont des emplacements différents : ils sont situés à des hauteurs et à
des latitudes différentes de l’arbre si bien qu’ils ne sont que partiellement visibles, même quand
le spectateur fait le tour complet de l’arbre ; enfin, les miroirs sont orientés de telle façon qu’ils ne
peuvent refléter les mêmes images : certains sont dirigés à droite, d’autres à gauche, d’autres plutôt
vers le haut, d’autres, encore, vers le bas. Au-dessous de ces rétroviseurs, des dates sont gravées sur
l’arbre marquant des évènements importants de l’histoire tunisienne. Les 17 dates vont de 1846,
année de l’abolition de l’esclavage, à 2014, année de la rédaction de la Constitution abrogeant
celle de 1959, en passant par la fondation du parti destourien (1934), l’indépendance (1956) ou les
émeutes du pain (1978). [...]"

Paratext as Moral-Ethical Orientation in Harriet Jacobs's <i>Incidents in the Life of a Slave Girl </i>(1861)
No full textIn the preface to her autobiography, Incidents in the Life of a Slave Girl, Written by Herself (1861), Harriet Jacobs makes explicit her “desire to arouse the women of the North to a realizing sense of the condition” of enslaved people (Jacobs n. pag.). The preface itself constructs an implied reader and gears their moral judgement towards condemning slavery. As is characteristic of the autobiographical genre, Jacobs’s narrative identifies her simultaneously as author, narrator, and protagonist. Thus, her “Preface by the Author” blurs the distinction between her textual status as narrator and her extratextual status as author. This conflation is key to constructing the implied reader of the narrative: the narrator does not address mere narratees but constructs the latter as real-life readers – women living in the Northern US – whose reading experience, the preface claims, could prompt a real-life sense of personal responsibility in the struggle against slavery. The rhetoric of the preface can be analyzed through the combined lenses of deictic theory and narrative ethics. Jacobs’s moral-ethical deixis includes markers like right/wrong, good/bad and true/false. Jacobs orients the implied reader towards Abolition, by instructing them to judge “Freedom” as good and “Slavery” as bad. Correspondingly, Jacobs associates slavery with “persecut[ion]” and “suffering” by presenting it as a “deep, and dark, and foul ... pit of abominations” (Jacobs n. pag.). This moral deictic system is solidified by Jacobs’s claim, as author-narrator, that to validate these ethical coordinates is to “realiz[e]” the truth (Jacobs n. pag.). The moral deixis of Jacobs’s preface is instrumental in constructing what James Phelan defines as “the ethics of the telling” and “the ethics of reading/reception” of the narrative (Phelan n. pag.). The invitation of the implied audience into Jacobs’s ethical perspective simultaneously assigns them “moral responsibilities” and “obligations” (Phelan n. pag.) vis-à-vis the diegesis and its narratio
Investigating Keystroke Dynamics and Their Relevance for Real-Time Emotion Recognition
No full textThere is strong evidence that emotional states affect the Human’s performance and decision making. Therefore, understanding Human emotions has become of great concern in the field of Human Computer Interaction (HCI). One way to online emotion recognition is through Keystroke Dynamics. It addresses the drawbacks of current methods which are intrusive and not user-friendly, expensive to implement, and neither realistic nor applicable in a real-world context. The keystroke dynamics approach focuses on analyzing the particular way a person types on a keyboard. In our research work, we start by developing a web application (EmoSurv) in order to collect the data and build a dataset. We generate datasets for free-text and fixed-text entries. These datasets are labeled with emotional states of the participants (Angry, Happy, Sad, Calm, and Neutral state). The obtained datasets are used for training and building models using machine learning algorithms. Outstanding accuracy rates are obtained reaching 93.922% and Kappa equal to 0.9197 using Random Committee algorithm. We finally provide a set of recommendations for future experimentation by comparing the different models generated

The dynamics of social representations in a situation of immigration
No full textFor the author, globalisation, defined as the internationalisation of exchanges, involves bearing in mind the migration issue in great national and international strategic concerns. Discourses on migration are closely linked with social representations in migratory events. This article constitutes an attempt to focus on the dynamics of social relations in a multicultural situation generated by migration, the objective of which lies in deconstructing the socialrepresentations of the immigrant. With the aim of establishing a theoretical framework for capturing the dynamics of immigrants’ representations and making the instability and fragility of these relations explicit, it presents a brief historical compendium of immigration, before situating the stages of the construction of the social representation, differentiating identity and otherness
Comparison of the Concentrations of Long-Chain Alcohols (Policosanol) in Three Tunisian Peanut Varieties (Arachis hypogaea L.)
No full textInternational audiencePolicosanol (PC) is a mixture of high molecular weight aliphatic primary alcohols. Literature about the contents and compositions of PC derived from peanut varieties is scarce. Total PC composition and content in whole peanut grain samples from three varieties of peanut (two cultivars, AraC and AraT, and a wild one, AraA) were identified using a gas chromatograph system coupled with a mass spectrophotometer. The results show that, qualitatively, 21 components of peanut aliphatic alcohols were identified (C(14)-C(30)). Besides (C(18=)), the results exhibited a previously unreported mixture of PC compositions in the peanuts: the unsaturated PC (UPC), which are (C(20=)), (C(21=)), (C(22=)), and (C(24=)). The main components of total PC in Tunisian peanut kernels are docosanol (C(22)), (Z)-octadec-9-en-1-ol (C(18=)), hexadecanol (C(16)), and octadecanol (C(18)). Quantitatively, the total PC content of the whole peanut samples varied from 11.18 to 54.19 mg/100 g of oil and was higher than those of beeswax and whole sugar cane, which are sources of dietary supplements containing policosanol
In vitro and in vivo evaluation of antifungal combinations against azole-resistant Aspergillus fumigatus isolates
No full textAzole resistance in Aspergillus fumigatus (Af) has become a widespread threat and a major concern for optimal management of patients with invasive aspergillosis (IA). Combination of echinocandins with azoles is an attractive alternative option for the treatment of IA due to azole-resistant Af strains. The aim of this study was to evaluate the in vitro and in vivo combination of caspofungin (CAS) with either voriconazole (VRZ) or posaconazole (PSZ). In vitro interactions were assessed by two methods, and an animal model of IA in Galleria mellonella was used for in vivo evaluation. Assessment of efficacy was based on larvae mortality. Groups of 10 larvae were infected by 3 clinical strains of Af (azole susceptible, AfS; PSZ resistant, AfR1; VRZ and PSZ resistant strain, AfR2). In vitro, combination of CAS and azoles was indifferent against AfS, and AfR2, and a synergy was found for AfR1. When compared to VRZ monotherapy, the combination of VRZ at 4 µg/larva with CAS at 4 µg/larva improved survival of AfR2-infected larvae (p=0.0066). Combination of PSZ at 4µg/larva with CAS at 4 µg/larva improved survival of AfR1-infected larvae compared to CAS (p=0.0002) and PSZ (0.0024) monotherapy. Antagonism was never observed. In conclusion, the combination of caspofungin with azoles is a promising alternative for the treatment of azole resistant strains of Af
Dynamic Delegation Based on Temporal Context
No full textAbstractDelegation is a very important part of the administrative process in access control systems; it provides resiliency and flexibility regarding to the management procedure. Delegation is the process of granting a specific authorization from a user to another user of the same system to carry out some functions on his behalf. The delegation, although widely used, is modeled in very little security policies because of its complexity. In this paper we aim to consider the delegation dynamically based on temporal context, to this end we redefine delegation for OrBAC using temporal nonmonotonic description logic. OrBAC is an access control model; it provides the mean to specify contextual authorizations, which facilitates modeling delegation features such as temporary delegation, multiple delegation, revocation, etc. The description logic that we use for the re-formalization process is T- JClassicδɛ. This logic gives the mean to specify nonmonotonic authorizations, and a better representation of the temporal aspects specific to a given delegation. This new representation augments the expressivity of the model and therefore it facilitates even more the representation and the management of the delegation characteristics
