In order to constrain the structural evolution in the central part of Burkina Faso and its implication for the emplacement of gold deposits, we undertook a structural mapping by coupling Landsat and aeromagnetic images interpretation to outcrop and core mapping followed by laboratory work. 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.
为了确定布基纳法索中部地区的构造演化及其对金矿床形成的影响,我们将大地遥感卫星和航空磁力图像判读与露头和岩心测绘相结合,进行了构造测绘,并随后开展了实验室工作。这种方法揭示了该地区的结构构造主要是由西北-东南走向的主要应力引起的右旋横向渐进变形造成的。这种结构类似于 Riedel-Tchalenko 模型。最初,主要的法向应力造成了东西向的收缩,从而形成了南北向的剪切走廊。随后,切向应力取代了法向应力,逐步形成了东北-西南走向的简单向外剪切带,这些剪切带局部被与里德尔 R 结构相关的东北-西南向外剪切带所占据。由于地壳冷却,我们看到了正弦NW-SE向和NNE-SSW向外的走向滑动断层的形成,这分别对应于Riedel's R'结构和Tchalenko's P结构。西北-东南向的前埃伯恩剪切带,特别是北-南剪切走廊的发展与含金流体通过该区域的循环同步。然而,这些定向走廊的交汇处形成了适合金浓缩的区域。在这些区域内,剪切带置入后产生的韧性-脆性变形促进了含金流体在具有适当流变条件的岩石中的再流动和富集。Toega 金矿床就是这种情况。

This article aims to explore the phenomenon of timelessness in Morocco through the insights of renowned travel writers such as Paul Bowles. 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.

This paper focuses on assessing the public value of e-government in Morocco, using Delone and Mclean's (2016) Information Systems (IS) success model as a reference framework. The methodology is based on a qualitative exploratory study involving 13 companies, including law firms, architecture firms, and real estate developers firms. 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.

This paper uses social movement theory to examine the rise and development of Boko Haram and AQIM into radical groups. 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.

Gender equity, quality education, and sanitation in rural and urban areas are widely considered development imperatives. 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.

Dans la plupart des zones productrices de riz pluvial de la Côte d’Ivoire notamment le département de Man, les producteurs de riz pluvial sont confrontés aux difficultés telles que l’enherbement. La présente étude vise à contribuer à la connaissance des communautés des adventices et leur degré d’infestation en vue d’une gestion efficiente de ces dernières. La méthode d’approche est une enquête réalisée auprès des riziculteurs et des relevés floristiques sur leurs parcelles ont été réalisés. Ces derniers ont permis d’évaluer les paramètres tels que les fréquences et l’indice d’abondance-dominance. Ainsi, grâce à ces paramètres, le diagramme d’infestation a pu identifier les adventices les plus abondantes. L’inventaire a permis de recenser 88 espèces réparties en 72 genres et 37 familles avec 72,72 % de Dicotylédones. Les familles les mieux représentées sont les Poaceae, les Cyperaceae et les Asteraceae. Les plus régulières et abondantes selon nos relevés sont Ageratum conyzoides Linn. et Calopogonium mucunoides Desv. Les riziculteurs ont identifié, Calopogonium mucunoides Desv. comme étant récurrente et nuisible lorsqu’elle n’est pas maitrisée assez tôt. The disturbance of the environment is at the origin of the destruction of the habitats, it contributes to the loss of the biodiversity and is one of the causes of the change of the flora in a locality. 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%). It therefore emerges from this study that Banco National Park remains a forest wi

Dans le district de Bamako, les cours d’eau sont le milieu récepteur privilégié des rejets des activités de teinture. Ces rejets, non traités sont source de problèmes environnementaux et sanitaires. L’objectif de cette étude est d’analyser les effets environnementaux et sanitaires de la teinture artisanale à Dianéguela en commune VI du district de Bamako. La méthodologie s’est appuyée sur l’observation directe, les enquêtes et l’analyse de certains paramètres qualitatifs de l’eau usée de teinture et des eaux de la rivière de Dianéguela. Par rapport à la turbidité, les résultats font ressortir respectivement 109 UNT pour le point A, 47 UNT pour le point B et 5 UNT pour le point C. La DBO, la DCO, l’oxygène dissous, la couleur, le pH, les orthophosphates, l’arsenic et la conductivité analysés ne répondent pas aux normes maliennes de rejet, ni à la grille d’évaluation relative aux eaux de surface de bonne qualité. Les effets sont la dégradation de la qualité des eaux de la rivière de Dianéguela avec une incidence négative sur l’environnement biophysique et la santé humaine ainsi que les nuisances olfactives. La gestion durable des effluents de teinture à Dianéguela nécessite la réhabilitation du centre de teinturerie, le traitement des eaux par une station d’épuration, la sensibilisation des teinturières, l’application rigoureuse de la règlementation. In the Bamako district, waterways are the preferred receptors for waste from dyeing activities. These untreated discharges are a source of environmental and health problems. This study aims to analyze the environmental and health effects of artisanal dyeing in Dianéguela in municipality VI of the Bamako district. The methodology was based on direct observation, surveys, and analysis of qualitative parameters of the dyeing wastewater and the waters of the Dianéguela river. Regarding turbidity, the results show 109 NTU for point A, 47 NTU for point B, and 5 NTU for point C, respectively. The BOD, COD, dissolved oxygen, color, pH, orthophosphates, arsenic and conductivity analyzed do not meet Malian discharge standards, nor the evaluation grid for good quality surface water. The effects are degradation of water quality in the Dianéguela river, with a negative impact on the biophysical environment and human health, as well as odor nuisance. Sustainable management of dyeing effluents in Dianéguela requires rehabilitation of the dyeing center, water treatment by a wastewater treatment plant, awareness-raising among dyers, and rigorous enforcement of regulations.
在巴马科地区,水道是染色活动产生的废物的主要接收地。这些未经处理的排放物是环境和健康问题的根源。本研究旨在分析巴马科区第六乡 Dianéguela 手工染色对环境和健康的影响。研究方法以直接观察、调查和分析染色废水和戴内盖拉河水的某些质量参数为基础。在浊度方面,结果显示 A 点为 109 NTU,B 点为 47 NTU,C 点为 5 NTU。所分析的生化需氧量、化学需氧量、溶解氧、色度、pH 值、正磷酸盐、砷和电导率均不符合马里的排放标准或优质地表水的评估标准。其后果是迪亚内盖拉河的水质恶化,对生物物理环境和人类健康造成负面影响,并产生异味。要对戴内盖拉的染色废水进行可持续管理,就必须修复染色中心,由废水处理厂对水进行处理,提高染色工人的认识,并严格执行相关规定。 在巴马科地区,水道是染色活动产生的废物的首选受体。这些未经处理的排放物是环境和健康问题的根源。本研究旨在分析巴马科地区 VI 市 Dianéguela 手工染色对环境和健康的影响。研究方法以直接观察、调查和分析染色废水和迪亚内盖拉河水的定性参数为基础。在浊度方面,结果显示 A 点为 109 NTU,B 点为 47 NTU,C 点为 5 NTU。分析得出的生化需氧量、化学需氧量、溶解氧、色度、pH 值、正磷酸盐、砷和电导率均不符合马里的排放标准,也不符合优质地表水的评估标准。其后果是迪亚内盖拉河的水质下降,对生物物理环境和人类健康造成负面影响,并产生异味。要对迪亚内盖拉的染色废水进行可持续管理,就必须修复染色中心,利用废水处理厂对水进行处理,提高染色工人的认识,并严格执行相关规定。

This paper examines how the compliance model improves corporate governance and efficiency post-financial crisis. This paper focuses on the goals of the compliance model, the strategies for its integration into corporate governance structures, as well as the results and conclusions. The compliance model prioritizes legal and regulatory compliance, ethical standards, and best practices in corporate governance. This methodology helps organizations prevent wrongdoing, enhance transparency, and build stakeholder confidence. Mixed methods study evaluates the compliance model. First, it reviews the theoretical and practical consequences of the compliance model. Next, a quantitative analysis compares pre- and post-compliance model performance metrics in a sample of firms. Finally, qualitative interviews with key stakeholders assess the impact of the model. This study shows that the compliance approach boosts post-financial crisis corporate efficiency. The approach improves corporate governance, malfeasance, and efficiency. Organizations with a culture of compliance, honesty, and responsibility gain stakeholder trust. The results show that the compliance model can help companies revive their corporate governance practices following financial crises. This methodology reduces risks, ensures legal and ethical compliance, and boosts efficiency and effectiveness. This study emphasizes the role of the compliance model in post-financial crisis corporate efficiency. It highlights the favorable effects of the model on corporate governance and organizational success. The report adds to the corporate governance literature and offers practical advice for companies trying to improve their governance in a complicated business environment.

En dépit de l’importance indéniable des recettes fiscales dans la constitution du budget de l’Etat et, par conséquent, pour le financement des projets d’utilité publique, un nombre de plus en plus élevé de contribuables en Côte d’Ivoire refusent de payer l’impôt en dissimulant leurs biens ou en les déclarant partiellement. La présente étude tente de comprendre cette situation en examinant l’incidence de la perception de la sanction encourue pour fraude ou évasion fiscale et de la perception de la justice sociale sur l’attitude à l’égard du paiement de l’impôt chez les chefs de ménage d’Abidjan. L’enquête porte sur un échantillon représentatif de 350 participants recrutés selon la technique de l’échantillonnage par quota. Les données sont recueillies grâce à un questionnaire et traitées à l’aide du test du « t de Student ». Les résultats obtenus corroborent nos hypothèses. D’une part, les chefs de ménage qui sous-estiment la sanction qu’ils encourent pour fraude ou évasion fiscale sont moins favorables au paiement de l’impôt que ceux qui surévaluent cette sanction. D’autre part, les chefs de ménage percevant une injustice sociale sont moins favorables au paiement de l’impôt que leurs pairs percevant une justice sociale. Ces résultats pourraient aider à l’élaboration de stratégies de sensibilisation plus efficaces pour favoriser la conformité fiscale volontaire. Despite the undeniable importance of tax revenues in the constitution of the state budget and, consequently, for the financing of public utility projects, an increasing number of taxpayers in Côte d'Ivoire refuse to pay tax by concealing their property or by partially declaring it. This study attempts to understand this situation by examining the impact of the perception of the penalty incurred for tax evasion or fraud and the perception of social justice on the attitude towards paying tax among heads of households in Abidjan. The survey is based on a representative sample of 350 participants recruited using the quota sampling technique. The data are collected through a questionnaire and processed using Student's t-test. The results obtained corroborate our hypotheses. On the one hand, the heads of households who underestimate the penalty they incur for tax fraud or evasion are less favorable to paying the tax than those who overestimate this penalty. On the other hand, the heads of households perceiving a social injustice are less favorable to the payment of taxes than their peers perceiving a social justice. These results may help in the development of more effective awareness-raising strategies to encourage voluntary tax compliance.
尽管税收对国家预算的构成以及公共事业项目的融资具有不可否认的重要性,但在科 特迪瓦,越来越多的纳税人通过隐瞒资产或只申报部分资产来拒绝纳税。本研究试图通过考察阿比让家庭户主对逃税或欺诈行为所受惩罚的看法以及对社会公正的看法对纳税态度的影响来了解这种情况。调查采用配额抽样技术,对 350 名参与者进行了代表性抽样。数据使用问卷收集,并使用学生 t 检验进行处理。结果证实了我们的假设。一方面,低估逃税或骗税惩罚的户主比高估惩罚的户主更不可能纳税。另一方面,认为社会不公平的户主比认为社会公平的同龄人更不可能纳税。这些结果有助于制定更有效的宣传策略,鼓励自愿纳税。 尽管税收对国家预算的构成以及公共事业项目的融资具有不可否认的重要性,但在科特迪瓦,越来越多的纳税人通过隐瞒财产或部分申报财产的方式拒绝纳税。本研究试图通过考察阿比让家庭户主对逃税或骗税所受惩罚的看法以及对社会公正的看法对纳税态度的影响来了解这种情况。调查采用配额抽样技术,对 350 名参与者进行了代表性抽样。数据通过问卷收集,并使用学生 t 检验进行处理。所得结果证实了我们的假设。一方面,低估骗税或逃税所受惩罚的户主比高估惩罚的户主更不愿意纳税。另一方面,认为社会不公正的户主比认为社会公正的同龄人更不愿意纳税。这些结果可能有助于制定更有效的宣传战略,鼓励自愿纳税。

L’objectif de cette étude était de déterminer le niveau de contamination des éléments traces métalliques (ETM) toxiques (arsenic, cadmium, mercure et plomb) dans des poissons consommés par les familles des pécheurs de Jacqueville, et ce dans le cadre d’une évaluation des risques chimiques liés à la consommation de poissons. Pour ce faire, 72 échantillons de poissons prélevés auprès de 81 foyers enquêtés et repartis entre 4 espèces, ont été analysés par spectrophotométrie d’absorption atomique. Il ressort que les traces des différents métaux existent dans les muscles (chairs) à des taux variables avec un dépassement des critères de comestibilité au niveau de l’arsenic et du cadmium. D’une part, Selene dorsalis avec 1,26 mg/kg, Sarotherodon melanotheron avec 1,33 mg/kg et Chrysichthys avec 1,27 mg/kg sont les poissons les plus contaminés en arsenic. D’autre part, Selene dorsalis avec 0,063 mg/kg et Sardina pilchardus avec 0,054 mg/kg présentent des niveaux de contamination cadmique élevés. Ces valeurs sont supérieures à la limite autorisée (0,05). Le risque pour ces consommateurs peut être réel du fait du caractère cumulatif lié à la toxicité de ces métaux, si les quantités consommées sont élevées. The purpose of this study was to determine the level of contamination of toxic trace metal elements (TME) (arsenic, cadmium, mercury, and lead) in fish consumed by the families of Jacqueville fishermen, as part of an assessment of chemical risks associated with fish consumption. To do this, 72 fish samples taken from 81 households surveyed and divided between 4 species, were analyzed by atomic absorption spectrophotometry. It appears that traces of different metals exist in the muscles (flesh) at variable levels with edibility criteria exceeded in terms of arsenic and cadmium. On the one hand, Selene dorsalis with 1.26 mg/kg, Sarotherodon melanotheron with 1.33 mg/kg and Chrysichthys with 1.27 mg/kg are the fish most contaminated with arsenic. On the other hand, Selene dorsalis with 0.063 mg/kg and Sardina pilchardus with 0.054 mg/kg present high levels of cadmium contamination. These values are greater than the authorized limit (0.05). The risk for these consumers can be real due to the cumulative nature linked to the toxicity of these metals if the quantities consumed are high.
