Making Tunisia non-African again – Saied’s anti-Black campaign
No full textInternational audienceSince last week, there has been a vicious campaign against sub-Saharan Africans in the streets of Tunisia, following comments by the president. Shreya Parikh writes how anyone who fits the category of ‘African’ – sub-Saharan students and documented or undocumented workers, as well as Black Tunisians are being harassed on the streets by police and civilians, and many attacked, stabbed, and forced into hiding
Being excess bodies: Shame in the age of climate coloniality
No full textInternational audienceFor many in the Global South, instead of recognizing that their suffering is a result of local and global socio-economic and racial structures, they feel shame. As COP27 takes place in Egypt, Shreya Parikh writes about climate change, overpopulation, and shame in Tunisia and India, and how suffering is often interpreted as being a result of individual deficiencies. It is a false narrative that blames those suffering most gravely from climate change for their own suffering
Racial time: The whiteness of the ‘glorious past’ in Tunisian popular histories
No full textInternational audienceShreya Parikh examines how popular narratives of Tunisia’s “glorious past,” particularly in La Goulette, celebrate colonial-era coexistence by centering white or white-passing European communities while erasing indigenous, Amazigh, and Black presences

Comparison of analytical techniques to evaluate the effect of drying on oxidative status of sliced almonds during storage
No full textAlmonds (Prunus amygdalus) are highest produced tree nuts worldwide, grown mainly in Mediterranean climate. Almond contains approximately 49% total lipids of which 12g is polyunsaturated fat, 30.9% monounsaturated fat and 3.7% saturated fat. About 90% of its total fatty acid composition is unsaturated, where oleic acid is 60-70% and linoleic acid 14-26%. The unsaturated fatty acids makes the almonds susceptible to oxidative degradation by producing volatile compounds, off flavor and odor decreasing their nutritional value. The deterioration rate of the almonds lipid fraction during storage due to the oxidative process is of a great economic and nutritional importance. Therefore, before storage the fruit is subjected to multi-processing steps in order to improve its quality in term of storage stability. In this connection, the drying step and storage conditions are of decisive importance. The drying step involves removal of moisture to prevent hydrolysis and enzymatic degradation during storage which cause split of triglyceride into glycerol and free fatty acid. However over drying or under drying could lead to oxidative degradation. The combination of various analytical techniques is recommended to evaluate oxidative status as no single method is available to analyze both primary and secondary oxidation products together. In this connection, this project aims at providing most effective analytical technique that evaluates the efficiency of the drying conditions on the storage stability of sliced almonds. Therefore, four different analytical techniques have been selected, namely: Iodometric titration for peroxide value, titration method for Free Fatty acid (Acid Value), UV spectrophotometry for conjugated diene and triene and GC/MS for semi-volatile and volatile compounds were used. This study shows a positive effect of the used drying conditions on the oxidative stability since the concentration of peroxides and conjugated dienes of dried almonds decreased as compared to those of non dried and ambient dried. A constant curve for free fatty acids was obtained showing that drying was done effectively as no hydrolysis has been observed. The GC-MS method seems to be the most suitable method which gives a real picture of drying effect on the oxidative status of the stored sliced almonds.M.S.Includes bibliographical referencesby Shreya D.

Design and characterization of three dimensional twist-braid scaffolds for anterior cruciate ligament replacement
No full textThe anterior cruciate ligament (ACL) is the most commonly injured ligament in the knee, with more than 350,000 ACL injuries reported annually in the United States. Current treatments include the use of autografts and allografts which have a number of disadvantages. Previous attempts to use synthetic materials in ligament replacement have been unsuccessful due to their inability to replicate the long-term mechanical properties of the native ligament. This project focuses on developing twist-braid poly(L-lactic acid) (PLLA) scaffolds for ACL replacement. Poly(ethylene glycol) diacrylate (PEGDA) was incorporated into the twist-braid scaffolds to evaluate its impact on their mechanical behavior. The twist-braid scaffolds were also compared with braided scaffolds. Scaffold mechanical properties were evaluated based on stress-relaxation, tensile and fatigue properties of the braided-only, twist-braid and the twist-braid scaffolds with PEGDA. All the scaffolds exhibited properties comparable to the native human ACL with the twist-braid scaffolds displaying resistance to fatigue. Scaffolds were seeded with rat patellar tendon fibroblasts. The cell viability and amount of protein released was studied over a course of 8 weeks. The scaffolds were stained with picrosirius red after 8 weeks to show the deposition of extracellular matrix by the cells. The results from this study showed that the twist-braid scaffolds have properties most suitable for ligament replacement.M.S.Includes bibliographical referencesby Shreya Madhavarap
La construction et la contestation de la blackness autour de la Méditerranée : cas de la Tunisie et de la diaspora tunisienne en France
No full textPar Shreya Parikh, doctorante au CERI-Sciences Po Paris et à l'Université de Caroline du Nord Ce travail doctoral en sociologie politique a été entamé à la rentrée 2020, à l’Université de Caroline du Nord à Chapel Hill et au CERI-Sciences Po Paris, sous la direction du Professeur Charles Kurzman (UNC) et du Professeur Daniel Sabbagh (CERI-Sciences Po). Il porte sur la construction et la contestation de la blackness en Tunisie et en France. Cette thèse vise à analyser la manière dont l’idée..
Review of Translating Blackness: Latinx Colonialities in Global Perspective by Lorgia García Peña (Duke University Press)
Get PDFIn Translating Blackness, Lorgia García Peña offers a transnational conceptualization of Black Latinidad. Framing Black Latinidad as an epistemology, García Peña traces its historical and contemporary formations through the lives and the work of historical Black Latinx intellectuals as well as contemporary Black and Black Latinx individuals in the Carribean, Italy, and the United States. García Peña approaches Black Latinidad as produced through vaivén—coming and going across physical and symbolic borders of nation-state and migrant-citizen categories that characterizes the sociological position of Black Latinx individuals
Remembering Jamila Debbech Ksiksi—An Interview with the Late Tunisian Lawmaker and Anti-Racist Activist
No full textMiddle East Report OnlineJamila Debbech Ksiksi, Black Tunisian activist and ex-member of parliament, died on December 19, 2022 in a traffic accident on the Tunis-Sfax highway, an accident which also killed her sister, Amel Debbech. Ksiksi was a key figure in the anti-racism movement in Tunisia. In collaboration with Black Tunisian and sub-Saharan civil society members, she helped mobilize against anti-Black racism following the revolution in 2011. Ksiksi and I met twice in Tunis in November of 2022 to talk about her political activism, past and present. Since we spoke, these interviews have taken on a new gravity, not only due to her untimely departure just a few weeks later but also due to recent events in Tunisia
The Limits of Confronting Racial Discrimination in Tunisia with Law 50
No full textIn 2018, Tunisia became the first country in the Middle East and North Africa to pass a law that criminalizes racial discrimination. In a society that has long denied the existence of racism, the law—popularly known as Loi 50 or Law 50—has been applauded by local activists and international human rights organizations as a historic step
