Full textThe Organization for the Harmonization of Business Law in Africa (OHADA), as it is based on a transfer of legislative and jurisdictional powers from the Member States to the joint organization, is seen to be a tool for legal integration. Indeed, OHADA combines both supranational and national norms and institutions. However, the operation of this system has not yet been comprehensively assessed. This study therefore aims to assess the ability of the OHADA system to achieve the desired integration of the African continent. To this end, it is necessary to review how the relationships between the bodies and norms of domestic law and those resulting from the Treaty establishing the supranational organization are articulated. Highlighting the features of legislative policy and legal technic that structure the OHADA Community construction will enable to identify the strengths and weaknesses of the system, and hence, to formulate proposals for improving this legal integration tool

Full textThis thesis addresses the problem of the abundance of activities in the informal economy in Africa that escape the control and regulation of the state. The objective is to participate through a legal debate of a continental dimension, to the analysis of the role of the entrepreneur in economic development. In the context of changing business law, it is particularly important to focus on the role of the entrepreneur as an economic actor. We propose a comparative approach in the light of French law to encourage business creation in the states of West Africa. With this in mind the OHADA legislator intervenes with a view to putting in place a simplified regulation allowing individuals to get into the business world, without subjecting themselves to severe constraints of legality. The integration of Entrepreneurship by the bill of revision of the Uniform Act on Company Law and Economic Interest Grouping of January 31, 2014, the Uniform Act on General Commercial Law of December 15, 2010, the Uniform Act relative to the law of cooperative companies of December 15, 2010, constitutes a fundamental lever.New regulations are now issued to professionals who were not governed by commercial law. This major innovation reflects this desire to involve all citizens in economic development. The purpose of the present study is to analyze the advantages and the disadvantages of this ease of management offered by OHADA law entrepreneurship through an overview of the uniform acts concerning the creation of a company. Finally, we discuss the relevance of this approach by comparing it with the very advanced French model of entrepreneurship. Through the importance given to micro credit, the diversification of financing methods, the formal sector, but also and above all to the change of status. The entrepreneur in OHADA law has enormous similarities with the status of auto-entrepreneur resulting from an innovation of French legislation by the law of modernization of August 4, 2008. Moreover, transitions can be envisaged, through the creation of commercial company.France offers a wide range of transitional modes ranging from the self-employed entrepreneur, the sole proprietorship, the one-man limited liability company to the creation of commercial company. It will also be necessary to emphasize the superficial nature of certain aspects of the entrepreneur's legal status. The scope of the rules governing this status is often limited because the legislator leaves it to the Member States to decide on certain points. This is undoubtedly what is at the origin of this lack of reconciliation of national logic with community dynamism. The concept of enterprising then raises many uncertainties, a synthesis of solutions could favor the maintenance of this status. The formalization of the informal economy is today a complex phenomenon, but essential to deal with the weak growth of African economies. Self-entrepreneurship is generally considered in France as a source of income supplement, while in Africa it is an important part of the subsistence economy

Full textDuring the past twenty years, a contingent approach of accounting information systems has grown because of changes in the industry and competitive conditions. This led researchers to think about the ability of accounting data systems to diversify, and to differentiate, depending on the context in which they are developped. This has led to studies aimed at analysing real and potential reactions of accounting data systems to organise complexification, and variations of uncertainty related to technological and economic changes. This thesis shows that dissemination factors such as the characters roles, the information supply through the communication channels, perception of the accounting innovations, and certain variables in the socio-economic environment, have an influence on the degree the usefulness of the accounting data system in small and medium enterprises

Full textCEMAC State members have recently experienced a strong economic growth. However, their relatively high rate of population growth is driving them to accelerate their GDP in order to create enough jobs, especially for the youth. This thesis is based on the premise that a banking system is key to financing growth. The goal is therefore to determine the keys to sustainable economic growth in this particular region. The improvement of banking governance, the strengthening of banks involvement in the financing of the economic zone, the supervision and control of banks activity and the compliance with its standards regulation is necessary to avoid systemic risks and to preserve the security of the depositors which ultimately guarantees the banking and economic stability of a State and enhances its growth. Despite a low rate of bancarization and active microfinance, the sub regional banking system is looking for a legal framework that will enable it to meet the challenge of financing development through banking inclusion and bancarization. In order for it to happen, we must consider the role of the BEAC in pursuing these objectives and the obsolescence of the banking monopoly in the CEMAC zone

Full textDue to the inadequate judicial processing of difficulties encountered by enterprises today, the right to prevention is becoming more and more attractive. In France as in Ohada, the law of July 26 2005 and the uniform act concerning collective procedures of passive clearance have stressed the importance of the negociated solutions in order to straighten the curve of the numerous company failures. On account of incitative mesures in favor of debtors and creditors, the confrontation of the French prevention system and the Ohada prevention system have limited results despite the quality of the various prevention systems. Even though the French prevention system, which appears to be better structured and better organized, serves as a model to the juidicial system of Ohada, it must be noted that both legislators are far from achieving their goals. In fact, company failures are increasing rapidly, highlighting the ineffectiveness of the judicial prevention mecanisms that have been proposed until now. Consequently, a reform of all prevention devices in both judicial orders is required. Moreover, the comparative approach set by this matter's principle aim is to develop a new approach in company law which henceforth advocates contractualization of the matter in order to make it more effective

Full textThe resurgence of banking and financial crises up the issue of financial security at the center of major policy issues of economic regulation. Indeed, the so-called subprime crisis and subsequent fiscal crises there, and the Cyprus crisis with a sense of public defiance that resulted, one may suggest that financial security will save the financial industry in spite of herself. This issue, more pragmatic moreover, seems to resonate more in law, unlike that of financial stability that appears rather subjective or incantatory. In Central Africa, as in the legal systems of Roman- Latin tradition, the question of financial security shall first the legal status of bank depositors, their place in the legal order of payment of creditors in the event of failure. But the question of the security of the banking system as interest credit institutions themselves, not simply because of the risky nature of their processing activities, but mainly because of the existence of systemic risk exacerbated by financial engineering. The question of safety arises therefore not simply in terms of protection of individual players , but more in terms of preservation or backup tool called economic banking and / or financial

Full textThe configuration of business law in Africa is intimately linked to its colonial history, a story of competition between powerful groups, evident today in the competition between legal systems. The process of “OHADA”, which started with such ceremony, has ultimately contented itself with an internal harmonization of the legal systems of countries with a civil law system. There is a notable correlation between the adopted rules and French business law. This “harmonized” law, therefore, ignores countries with common law systems, the other facet of the African legal landscape, generating tensions between lawyers on both sides.Nevertheless, the divisions are not limited to the dichotomy civil law-common law. Informal regulation exists alongside both these legal systems, and they must be taken into account if the rules that govern business in Africa are to be understood. This generates a multiple challenge: bringing OHADA law and common law closer is both desirable and possible. The proximity between these people and countries is too close to justify the existing differences. Nevertheless, bringing common law and OHADA closer, does not mean replacing them with a new common system, which seems unrealistic. Compatibility, rather than uniformity, would be the desired result, offering a better fit with the search of attractiveness, which is in the essence of business law. This study therefore promotes an open approach of the “other” system, while underlining the importance of the informal sector, based on custom and usages

Full textThe African continent is distinguished by the proliferation of organizations with an integrative vocation. These organizations adopt acts that are binding on the Member States as well as on community structures and which are intended to be applied to individuals. In this context, Community courts are called upon to play a central role in the integration process.It appears, however, that the Community jurisdictions of Africa in general and of West and Central Africa in particular still play a rather unclear role, hence the trampling of the integration process.What factors hinder the full effectiveness of these jurisdictions and what improvements could be made to make them engines of regional integration? To answer these questions we are interested both in the vertical relationship involving jurisdictions, Member States and Community institutions, as well as in the horizontal relationship, that is to say with national courts on the one hand and Community courts on the other. A restructuring as well as a re-reading of the different lines of law are then proposed

Full textThe undertaken research deals with the evaluation of the OHADA accountancy system of reference aptness to express accurately the factual economic reality experienced by the beninese enterprises and particularly to enable the financial performance assessment of these enterprises.The philosophy originates in the idea that one manages only what can be assessed, and that it is necessary to make sure the different bases of management and investment decisions are reliable, as well as the economic policies.The investigation led on a representative range of more than three hundred accountancy information producers and users help us make their needs and the degree (level) of satisfaction of these needs stand out.The carried out work reveal the weaknesses at the base (root) of the accountancy information systems implemented by the Beninese enterprises, what leads to question the reliability of the provided financial statements. To compensate this inadequacy, a model of data base management has been proposed so as to ameliorate the collection of these data, and all the decision process, to ease the potential investors and above all to make more efficient the government economic orientations

Full textThe social leaders are at the heart of the problem of the governance of societies. The legislator OHADA, resuming rule taken of his French counterpart, in the law of 1966, established a set of rules applicable to the leaders.These rules are relative to the organization to the social functions, to the powers devolved to the leaders or still to the responsibility and to the system of revocation who are applicable to them. However, if it is necessary to recognize in the right of OHADA the merit to have structured and unified the system formerly marked by the disparity and the archaism, the fact remains that it resumes the faults of the French system.Indeed, the later is marked, on one hand, by the absence of a unique status for the leader and, on the other hand, by a certain dualism and imbalance between the leaders. It is there for example so when we consider the system of revocation of the leaders, which assures a protection for some while others live in a relative instability. This disparity also shows itself through the liability scheme obliging to distinguish according to the patrimonial situation of the society.The object of the present thesis will be, after having established an inventory of the effort of structuration by the uniform loi, to draw up lines of thought for the emergence of good governance

O presente trabalho objetivou analisar a aplicabilidade das normas de tratados internacionais no direito comercial particularmente no caso do Tratado da OHADA na Guiné-Bissau do ponto de vista jurídico-constitucional e de direito internacional. Analisam-se na presente pesquisa os conflitos emergentes com a adesão da Guiné-Bissau a essa organização internacional não olvidando as teorias clássicas sobre o tema isto é as teorias monista e dualista. Neste caso enfatizou-se a problemática da supranacionalidade da OHADA a questão da aplicação direta e obrigatória dos seus atos normativos por parte dos Estados-Membros e na falta de normas constitucionais guineenses respeitantes à relação com as normas do direito internacional verificou-se quais as possíveis soluções oferecidas pela doutrina. Ademais procurou-se comparar os dois ordenamentos jurídicos com a finalidade de constatar as inovações introduzidas pelos atos normativos da OHADA considerando que não houve uma revogação total e global das normas comerciais vigentes. Tudo isso sem perder de vista a análise do seu ordenamento jurídico e suas características. Foi observado por outro lado que a Guiné-Bissau não somente carece de preceitos sobre o valor que as normas internacionais ocupam no seu direito interno, como também constatou-se que não admite a supranacionalidade, constituindo assim um verdadeiro obstáculo à integração política e supranacional visada pela OHADA.

Full textAkinesia is a principal feature of Parkinson's disease. The word akinesia literally means absence of movement. Akinetic symptom in depression and schizophrenia embodies the hypothesis that akinesia involves more than only motor behaviour. Moreover, these disorders have all been associated with evidence of dopamine disrupted homeostasis in the central nervous system. We intended to relate the respective involvement of the nigrostriatal and mesocortical pathways to akinesia. We used a partial bilateral lesioned model of the substania nigra pars compacta (SNc) or ventral tegmental area (VTA). Neuroanatomical study showed that only VTA lesions increased the level of D1 binding in cortical areas. In a second step, we studied the relative effect of lesions on motor and basic cognitive processing. This study highlighted the difference between a "nigral syndrome" (mainly motor) and a "tegmental syndrome" mainly cognitive)

Full textBeyond motor symptoms, Parkinson’s disease (PD) is also characterized by a plethora of neuropsychiatric deficits, ranging from apathy and depression to Impulse control disorders (ICDs). ICDs represent a complex group of behavioral addictions including gambling disorders, hypersexuality and compulsive shopping, displayed by 10 to 14% of PD patients under dopamine replacement therapies, whose quality of life is greatly diminished. Importantly, cognitive impulsivity reflecting in particular, an inability to tolerate delays to reinforcements, appears as a core symptom of ICDs. Indeed, recent evidence suggested that this kind of impulsivity would be exacerbated in PD and under treatment by dopaminergic D2/3 receptor agonists. However, the mechanisms underlying ICDs in PD remain unknown and the respective contribution of dopamine lesion and treatment, combined with factors of vulnerability, remain to be determined. Moreover, waiting impulsivity, another form of behavioral inhibition which may lead to compulsive behaviors, has been poorly investigated in the framework of ICDs.In this thesis project, using a lesional rodent model of non-motor symptoms of PD, we addressed the question of whether denervation of the dopaminergic nigrostriatal system would promote the development of impulsivity when combined with dopamine agonist treatments. Rats were bilaterally injected in the SNc with the neurotoxin 6-OHDA to induce selective and partial denervation of the dorsal striatum. We then treated them with the dopamine D2/3 receptor agonist, pramipexole, a medication known to favor the development of ICDs in PD patients. Two different tasks were used to measure cognitive and motor impulsivity: the delay discounting task (DDT) and the 5-choice serial reaction time task (5-CSRTT) respectively. In the former, rats have to press a lever and choose between a smaller, but immediate reward and a larger, but delayed reward. For the latter, they have to wait for a stimulus light to come on. In the DDT, chronic administration of pramipexole treatment only increased impulsive choices in non-lesioned rats. Indeed, the dopaminergic lesion by itself, or in adjunction with the treatment, did not increase impulsivity. In the 5-CSRTT, pramipexole progressively increased premature responses, reflecting a pro-impulsive effect when the inter-trial interval is constant. However, when the interval was increased, pramipexole reduced the premature responses, exhibiting an anti-impulsive effect. Interestingly, this modulation of motor impulsivity was only observed in rats with a high level of impulsivity, suggesting that an impulsive endophenotype might be an important factor of vulnerability to the iatrogenic effects of pramipexole.The effect of this treatment was then investigated at a cellular level. It promotes overexpression of the dopamine D2 receptor mRNA within the striatum, and seems to alter glutamatergic synaptic connectivity suggested by electron microscopy. Moreover, we showed that the mammalian target of rapamycin complex 1 (mTORC1) pathway is lastingly over-activated in the nucleus accumbens, as already observed in drug addictions. In an attempt to make a causal link between this pathway and the behavioral changes, we treated rats with pramipexole and rapamycine, a specific inhibitor of this pathway. Surprisingly, this combination accentuated impulsivity even more, whereas rapamycine by itself did not promote impulsivity. This effect may be explained by the complexity of the kinetics of activation and inhibition of mTORC1 pathway.Taken together, these results suggest that impulsivity in PD may be triggered by an iatrogenic effect of the dopaminergic pramipexole treatment through an abnormal activation of the mTORC1 pathway within the nucleus accumbens

Full textThe purpose of the work was to evaluate the biochemical and behavioral effects of a new peptide, Informatin-1. Binding experiments on rodent brain sections first showed a very specific distribution of its binding sites, in the caudate-putamen nucleus (CPu) and substantia nigra (SN). Informatin-1 induced an increase in contralateral rotations to the injection site in the CPu and SN. Besides, the hypothesis of an interaction with the dopaminergic system was tested by behavioral experiments using D1 and D2 receptor antagonists. The results indicated an involvement of these receptors in the dopamino-mimetic effect of Informatin-1. The sensorimotor territory of the CPu being more enriched in Informatin-1 binding sites than the limbic/prefrontal(PF) territory, behavioral studies were performed in the both territories. Informatin-1 bilaterally injected induced an increase in locomotor activity and oral behaviour in the sensorimotor and limbic/PF territories respectively. The study was then focused in the sensorimotor territory, showing that Informatin-1 increases dopamine release in vitro and in vivo in this territory. This effect of Informatin-1 on the dopaminergic system was showed to be indirect. Finally, Informatin-1 prevents acetylcholine release in the sensorimotor territory when dopaminergic transmission is blocked. The whole study allowed to obtain important results on the mode of action and behavioral impact of Informatin-1, suggesting its possible therapeutic interest
