This approach reveals that the structural architecture in this locality mainly results from dextral transcurrent progressive deformation due to a NW-SE trending major stress. This architecture is similar to the Riedel-Tchalenko model. Initially, the dominant normal stress created an E-W constriction resulting in the development of N-S shear corridors. Subsequently, the tangential stress that took over this generated the progressive development of simple dextral shear zones with a NE-SW orientation that are locally taken up by ENE-WSW dextral shear bands associated with the Riedel's R structures. As a result of the cooling of the crust, we are witnessing the formation of sinistral NW-SE and dextral NNE-SSW strike-slip faults, respectively, which corresponds to Riedel's R' structures and Tchalenko's P structures. The development of NW-SE pre-Eburnean shear zones, particularly the N-S shear corridors, is synchronous with the circulation of gold-bearing fluids through the zone. However, the intersections of these directional corridors create zones suitable for gold concentration. Within these zones, ductile-brittle deformation following the emplacement of the shear bands has facilitated the remobilization and concentration of gold-bearing fluids within rocks with the appropriate rheological conditions. This is the case for Toega gold deposit. \u0000  \u0000 ","PeriodicalId":12225,"journal":{"name":"European Scientific Journal, ESJ","volume":"94 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140477753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The semi-systematic method was used primarily due to the limited amount of research done on the topic of timelessness. It will analyze the representations of Morocco in Western discourse, particularly in the context of Western Orientalism. Thanks to decolonization, deconstructionism, and Edward Said’s Orientalism, hitherto neglected travel writing has elicited academic responses from scholars who have recognized that travel writing is not simply an innocent and objective description of a traveler’s encounters in a foreign land. Instead, it is a genre that is inherently political, intertwined with projects of orientalism, colonialism, imperialism, and post-colonialism, and characterized by a hegemonic gaze directed towards the other, often marginalizing the voices of peripheral people. This research references books, notable authors, and Western explorers who commonly mention the unchanging quality of time in the Orient, particularly in Morocco. Additionally, the study will draw on the insights of Edward Said to explain why this timelessness was prevalent in the 20th century.","PeriodicalId":12225,"journal":{"name":"European Scientific Journal, ESJ","volume":"20 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140470589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An interview guide was designed to collect data, which were analyzed using Nvivo Qsr 12 software. The analysis identified six variables, namely: \"Human Capital, Telecommunication Infrastructure, Willingness to Use, State Strategy, Continuous Education, and Culture,\" which were added to the seven predetermined variables of the Delone and Mclean (2016) IS Success Model. This research outlines practical implications that are essential for the long-term success of e-government initiatives in Morocco. These include investing in skills development, effectively communicating the benefits of e-government, promoting collaboration between the public and private sectors, recognizing organizational culture, putting mechanisms in place to measure performance and user satisfaction, as well as making adjustments to organizational processes and rigorously managing data security. On a political level, these adjustments underline the importance of a coherent government strategy, which focuses on strengthening human capital and telecommunications infrastructures, in order to promote a successful digital transformation and achieve the objectives of trust, transparency, and efficiency in public services.","PeriodicalId":12225,"journal":{"name":"European Scientific Journal, ESJ","volume":"148 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140478765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Boko Haram and AQIM were initially established as moderate and conservative Islamist groups in Nigeria and Algeria respectively. AQIM was originally a political party – the FIS but changed names to the GIA, the GSPC, and AQIM each with a different modus operandi. Boko Haram was a local organization that has been espousing an anti-system frame alongside violent tactics since 2009. Relying on secondary data, this paper found that the emergence and eventual transformation of Boko Haram and AQIM into radical movements signify the existence of social movement factors of political opportunity structures, mobilizing structures, and framing processes in Nigeria and Algeria. Results from content analysis of the data show that while the two movements emerged in two distinct socio-economic and political environments, they were rational actors who continued to utilize the available political structures opportunity, mobilizing structures and framing processes to mobilize and sustain collective actions. It is evident that government repression only made the two groups change tactics and strategies when what they regarded as free spaces diminished at times they gathered material and non-material resources. That coincided with the radical views of some of the groups’ members, the presence of mobilizing structures, and a frame resonance that ensured recruitment into the two movements.","PeriodicalId":12225,"journal":{"name":"European Scientific Journal, ESJ","volume":"34 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140477739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, many developed countries have scientifically and technically developed norms for the calculation and the design of toilet and urinal needs of their students, which is not yet the case in most developing countries, including the Republic of Benin, that lack socio-culturally adapted gender-specific toilets and urinal needs calculation and design norms. This paper fills this scientific and gender-specific norms gap, by discussing the process and the results of the design of school toilet and urinal needs calculation templates and norms in the Republic of Benin. The study that led to this design took place between June 2013 and October 2015 and consisted mainly of observing and recording defecation and urination needs satisfaction in toilets and open spaces by 8,160 female and 13,263 male students of 13 schools purposively selected in four agroecological and sociocultural areas of Benin. The main data recorded related, among other data, to the start and end times of the use of the toilets and open spaces; the needs satisfied; the peak times and durations of breaks and of toilet needs satisfaction; the numbers of female and male students and non-students who use and who can potentially use the toilets and urinals. These raw data were processed to infer and calculate eight parameters used in each template. This process led to the design of eight area-, gender-, and disability-specific templates and norms in use since 2016, in the target areas. Further studies will assess and report on the performance of these templates and norms.","PeriodicalId":12225,"journal":{"name":"European Scientific Journal, ESJ","volume":"205 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140476031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It therefore leads to the transformation of plant associations. The main objective of this study is to research the plant associations in the Banco National Park following village plantations and silvicultural trials due to the search for a methodology specific to African silviculture. To do this, the phytosociological characterization of the former treatment sites and the forest reserve was carried out. The method used is that of synusial phytosociology. The 91 surveys (82 in the former silvicultural treatment sites and 9 in the forest reserve) made it possible to identify 337 species of plants divided into 65 families and 268 genera. The dendrogram resulting from the ascending hierarchical classification of the readings revealed three syntaxa, two of which essentially consist of the readings of the old treatment sites and one of the readings of the forest reserve. No syntaxon contains all the characteristic species of the Turraeantho-Heisterietum association. However, in two syntaxa, the proportion of characteristic species of this association is greater than 50%. 70.59% in the syntaxon to Tarrietia utilis and Cola heterophylla (syntaxon from secondary forests), 52.94% in the syntaxon to Cola chlamydantha and Drypetes chevalieri (syntaxon from the forest reserve). While in the Dacryodes klaineana and Pleiocarpa mutica syntaxon (secondary forest syntaxon), 41% of these characteristic species were recorded. Species characteristic of other forest formations are also poorly represented in the syntaxa (less than 40%).
