ABSTRACTThis study examines the issue of postcolonial psychological oppression in AyiKweiArmah’sThe Beautyful Ones Are Not Yet Born. This study aims at depicting the changes in Ghana brought by colonialism and to describe the situation of the Ghanaian and African society. The study employs postcolonial psychoanalysis theory led by Franz Fanon and Albert Memmi. It examines the psychology of the oppressed in The Beautyful Ones. Hence, the first chapter sheds light on the socio-hisorical and the theoretical framework. Besides, the second chapter scrutinizes the troubled psychologies of Armah’s characters. The study concludes that the colonial legacy of oppression continued to affect the post-colonial realities of the oppressed.

The huge development of Internet has led to an increasing in the use of networking and social networking sites (Facebook, Twitter, etc) resulting in huge amounts of data over the networks. These data are not useful and meaningful. Therefore, it is necessary to analyse these data to extract knowledge so as to benefit from it in many purposes, for example election data, finance data, sports data, etc. Referring to that the idea of opinions analysis raised to know the meaning of the large amount of data passing through Web. The sentiment analysis is one of the most important techniques that have a significant impact on social networking sites. The process of finding positive and negative data manually is very difficult from social networking sites. The lexicon based approach is one of the approaches method used in the analysis and classification of data. Lexicon based method are similar to machine learning algorithm, which is one of the most commonly used to solve most problems of automatic classification. The main objective of this research is to solve the problem of data analysis automatically in shortest possible time to get informative results from Twitter posts and comments. The word extraction process is done by fragmentation and aggregation of views. In this research we proposed a lexicon based approach to analyse social networking data. The proposed method has been implemented on data collected from Twitter site. The method collects and classifies the data into positive or negative Tweets. The proposed method has tested using three datasets collected from Twitter each dataset is about specific topic (best football player, Messi player, Tramp ) presented for the comments. The results show that the proposed method can classify the comments in shortest possible time. The method can collect 500 comments and classify them into positive or negative tweets within 5 minutes or less than. The study recommends integrating Lexicon based approach with the machine learning algorithm to improve the performance for textual data analysis.

شهدت منطقتي الغرب الجزائري والمغرب الأقصى خلال الفترة الممتدة ما بين القرنين 18م و19م حركة تواصل ثقافي أكدت مدى الترابط الفكري والحضاري بين شعوب المنطقة فالبرغم من وجود متغيرات عديدة عرفتها كلا المنطقتين إلا اننا نجد ان هناك الكثير من الرحلات العلمية المتبادلة بين علماء المنطقتين وكذلك التبادل المستمر للكثير من الإجازات العلمية والمصنفات وتبادل الرسائل المختلفة.

Background: Macroautophagy is a highly conserved catabolic process among eukaryotes. Autophagosome is a piece of double-membrane machinery that fuses with lysosomes to form autolysosomes. Autolysosome degrades organelles and organizes the pathogen engulfment during phagocytosis in innate immunity. Macrophages are highly dynamic immune cells that orchestrate the host-pathogen interaction. Interestingly, autophagy is implicated in disease pathophysiologies such as Crohn’s disease, cancer, and neurodegenerative diseases. Therefore, this work aimed to study the interplay between autophagy and macrophage polarization (activation) through two approaches, first to construct the genetic regulatory network and pathway analysis. And to predict the target proteins that mediate the interplay between autophagy and macrophage activation(polarization). Followed by an in vitro experimental validation of target proteins using immune co-localization studies, flow cytometry studies, laser confocal microscopy studies, and gene expression analysis. Methods: A systems biology approach was performed to find the interplay between Autophagy related genes (Atgs) & Differentially expressed genes of Macrophage Polarization M1-M2 (DEGs), followed by common pathway enrichment and construction of transcription factors and mi-RNAs regulatory networks. The Atgs and DEGs targets that mediate the interplay between autophagy and macrophage polarization were defined, and experimental validation for targets took place. Bone marrow-derived monocytes were isolated from the femur and tibia of female mice. After differentiation of monocytes to M0, M1, and M2a, the lineage phenotypes were characterized using flow cytometry. Afterward, we validated the targets of Smad1, LC3A&B, Atg16L1, Atg7, IL6, CD68, Arg-1, and Vamp7. Finally, we investigated the impact of autophagy inhibition on all immune lineages using autophagy inhibitor Bafilomycin-A. Results: Immune phenotyping by flow cytometry revealed three macrophage phenotypes: (IL6+/CD68+) M0, (IL6+/CD68+/Arg-1 +) M1 and (CD68+/Arg-1) M2a lineages. And 3D reconstruction of laser confocal microscopy Z-stalk images revealed an increase of autophagy activity in both M1 and M2a lineages. Besides, a significant increase was observed in pre autophagosome size and number of Atg-7, Atg-16L1 in interleukin -4 activated M2a cells compared to control M 0 naïve cells. The size of LC 3 A& B auto phagosomal aggregates showed an increase in M2a cells. RT qPCR supported these findings and showed the high gene expression profile of Atg 16 L 1- 3, Smad1, and Vamp 7 in M2a lineage. Bafilomycin –A, an autophagy inhibitor, induced increased expression of CD68 and Arg-1 in all cell lineages. Phagocytosis assay with Heat killed E Coli bacteria showed decreased phagocytosis activity in IL-4 activated M2a cells but not M1 cells. Conclusion: This study suggests that autophagy reprograms macrophages through CD68 and Arginase-1 phagocytosis markers and Atg 16 L 1 -3 dependent manner.
