Medical research on human subjects in South Africa : a critical assessment of the work of research ethics committees

Moodley, Keymanthri 12 1900 (has links)
Thesis (DPhil)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: Human participant research raises a conflict between medical progress as a societal good and the protection of participants as an individual good. Prior to 1960 the discretionary authority for the protection of participants resided in the hands of individual investigators. However, a wave of research atrocities from Tuskegee in 1932 to the Beecher expose in 1966 stimulated a change to a principle based system of regulation. Research Ethics Committees (RECs) and Institutional Review Boards (IRBs) were henceforth charged with the responsibility of human participant protection. Since 1966, this system of research review was established internationally and at one institution in South Africa. In 1997, placebo-controlled HIV vertical transmission trials in a number of developing countries including South Africa raised unprecedented controversy in research ethics internationally and nationally. In 2000, the fraudulent breast cancer trials conducted by Dr Bezwoda at Baragwanath Hospital drew international attention to research ethics in South Africa. However, the events that called into question the efficiency of the system of ethical review most poignantly were the recent deaths of volunteers in research at centres of excellence in the United States. It was charged that if there were deficiencies in the research ethics review system in developed countries, these were more likely to be present in developing countries. Around the same time the Interim National Health Research Ethics Committee (INHREC) was established in South Africa to explore and regulate the ethical review system in South Africa. Cognisant of these issues, the current study was undertaken to establish the various structural, procedural and substantive ethical challenges facing justifiable and ethical review of research in South Africa. A combination of conceptualphilosophical reflection and empirical research was employed in this dissertation. The empirical work employed both quantitative and qualitative research methodology. The quantitative survey explored the composition of RECs reviewing clinical trials research in South Africa with an emphasis on committee composition and structure as well as the review process. The qualitative research was conducted using semi-structured interviews of ten REC Chairpersons in South Africa to explore complex substantive issues like informed consent, standards of care and participant remuneration, inter alia. While the review system in South Africa is functioning at a reasonable level, there is wide variation from one REC to the next. RECs are geographically distant and function in isolation without opportunity to communicate and share ideas. Amongst institutional RECs, there is a stark contrast between historically disadvantaged institutions and historically advantaged institutions. REC membership, ten years into democracy remains white male dominated. Community representation is inadequate. Most RECs are dominated by scientists and clinicians. The review process is widely variable with delays in review ranging from ten days to ten weeks. Procedural and bureaucratic demands impact on the ability of REC members to engage in debate on important substantive ethics issues like standards of care, informed consent and participant remuneration. Research ethics training and educational needs vary widely across the country. Serious attention must be paid to the way in which RECs are constituted in South Africa. Restructuring of RECs with a view to improving representation in terms of race, gender and religion must be prioritized. There is a need for community representation and non-scientific membership to be explored. RECs in South Africa need to revisit the question of whether they should be conducting both scientific and ethics review or ethics review alone. The review process requires a paradigm shift in emphasis from adverse event reporting to monitoring, from informed consent forms to a culturally relevant informed consent process. Aparadigm shift is indicated to shift the focus from informed consent to a more comprehensive review framework. Policies regarding standards of care and participant remuneration must be clarified and articulated. Although the role of RECs in human participant protection has been questioned, it is clear that in the vast majority of cases, they are fulfilling an important role. Their function could certainly be enhanced. This is being facilitated by training programs and an electronic newsletter. However, responsibility for human participant protection does not reside in the domain of the REC alone. A collective responsibility shared by researchers, institutions, research ethics committees, sponsors and participants is integral to human participant protection and the generation of new, valid and relevant scientific knowledge. / AFRIKAANSE OPSOMMING: Navorsing op menslike subjekte gee aanleiding tot ‘n konflik tussen mediese vooruitgang as ‘n voordeel vir die samelewing en die beskerming van deelnemers as iets waarby die individu direkte belang het. Voor 1960 het die diskresionêre gesag vir die beskerming van deelnemers by die individuele navorsers berus. ‘n Golf van navorsingsvergrype, van Tuskegee in 1932 tot die Beecher onthulling in 1966, het egter veranderinge in die rigting van ‘n stelsel van beginsel-gebaseerde regulasie gestimuleer. Navorsingsetiekkomitees (NEKs) en Institusionele Beoordelings- en toesigrade (IBRs) is gevolglik belas met die verantwoordelikheid om toe te sien dat mense wat deelneem, sover moontlik beskerm word. Sedert 1966 is hierdie stelsel van navorsingshersiening en -toesig internasionaal tot stand gebring – ook, aanvanklik, by een instansie in Suid-Afrika. In 1997 het plasebo-beheerde HIV-vertikale oordrag-proewe in ‘n aantal ontwikkelende lande, insluitend Suid-Afrika, tot ongekende kontroversie op die terrein van navorsingsetiek aanleiding gee, internasionaal en nasionaal. In 2000 het die bedrog met borskankerproewe, uitgevoer deur dr Bezwoda by Baragwanath Hospitaal, internasionale aandag op navorsing in Suid-Afrika gevestig. Hierdie gebeure het egter die effektiwiteit van die stelsel van etiese toesig in Suid-Afrika en elders in die wêreld bevraagteken. Die mees kommerwekkende onlangse insident was die dood van navorsingsvrywilligers by sentra van uitmuntendheid in die Verenigde State. Daar is beweer dat as daar tekortkominge in die navorsingsetiektoesigsisteem in ontwikkelende lande is, daar ‘n groter moontlikheid bestaan dat dit ook (en moontlik meer) in ontwikkelende lande voorkom. Ongeveer dieselfde tyd is die Interim Nasionale Gesondheidsnavorsings-etiekkomitee (INGNEK) [Interim National HealthResearch Ethics Committee (INHREC)] in Suid-Afrika gestig om die etiekoorsigstelsel in Suid-Afrika te ondersoek en te reguleer. Met dit in gedagte is die huidige studie onderneem om die verskillende strukturele-, prosedurele- en substantiewe etiese uitdagings wat regverdigbare en etiese oorsig van en toesig oor navorsing in Suid-Afrika in die gesig staar, vas te stel. Daar is van ‘n kombinasie van konseptuele, filosofiese refleksie en empiriese navorsing in hierdie proefskrif gebruik gemaak. Die empiriese werk maak gebruik van sowel kwantitatiewe as kwalitatiewe navorsingsmetodes. Die kwantitatiewe opname bestudeer die samestelling van NEKs wat toesig hou oor kliniese proewe in Suid-Afrika, met die klem op komiteesamestelling, -struktuur en die toesigproses. Die kwalitatiewe navorsing is gedoen met behulp van van semi-gestruktureerde onderhoude van tien NEK-voorsitters in Suid-Afrika om die komplekse substantiewe aspekte, soos onder andere ingeligte toestemming, standaard van versorging en deelnemervergoeding, te ondersoek. Terwyl die etiek-toesigstelsel in Suid-Afriks op ‘n redelike vlak funksioneer, is daar ‘n groot verskil tussen verskillende NEKs. NEKs is geografies verspreid en funksioneer dikwels in isolasie sonder ‘n geleentheid om te kommunikeer en idees te deel. Ten opsigte van die institusionele NEKs bestaan daar ‘n duidelike kontras tussen histories benadeelde instansies en histories bevoordeelde instansies. NEK-lidmaatskap word, tien jaar na demokrasie, steeds gedomineer deur blanke mans. Gemeenskapsverteenwoordiging is onvoldoende. Die meerderheid NEKs word gedomineer deur wetenskaplikes en klinici. Die toesig- en hersieningsprosesse in die verskillende komitees verskil grootliks, met vertragings wat wissel van 10 dae to 10 weke. Prosedurele- en burokratiese vereistes het ‘n impak op die vermoëns van NEK-lede om by debatte oor belangrike substantiewe etiese aangeleenthede betrokke te raak, soos byvoorbeeld die standaard van versorging, ingeligte toestemming en deelnemervergoeding. Opleiding en opvoedkundige behoeftes verskil wyd oor die land.Ernstige aandag moet geskenk word aan die wyse waarop NEKs in Suid-Afrika saamgestel is. Herstrukturering van NEKs met ‘n visie op verbeterde verteenwoordiging in terme van ras, geslag en geloof is ‘n prioriteitsvereiste. Gemeenskapsverteenwoordiging en lidmaatskap van nie-wetenskaplikes moet verder ondersoek word. NEKs in Suid-Afrika moet die vraag of hulle sowel wetenskaplike- as etiektoesig moet uitvoer, of sl slégs etiektoesig, opnuut ondersoek. Die nasiensproses vereis ‘n paradigmaskuif, vanaf ‘n klem op rapportering van gebeurtenisse, na monitering van ingeligte toestemmingsvorms sowel as na ‘n kultureel toepaslike ingeligte toestemmingsproses. ’n Paradigmaskuif is noodsaaklik ten einde die fokus te verskuif vanaf ingeligte toestemming na ‘n meer omvattende toesig- en nasiensraamwerk. Beleid rakende standaard van versorging en deelnemervergoeding moet verduidelik en geartikuleer word. Alhoewel die rol van NEKs in die beskerming van menslike deelnemers aan navorsing bevraagteken word, is dit duidelik dat NEKs in die meerderheid van gevalle wel ‘n belangrike rol vervul. Hul funksie kan natuurlik uitgebrei word. Dit sal gefasiliteer word deur opleidingsprogramme en ‘n elektroniese nuusbrief. Verantwoordelikheid vir die beskerming van mense wat deelneem aan navorsing berus egter nie uitsluitlik by NEKs nie. ‘n Kollektiewe verantwoordelikheid, gedeel deur navorsers, instellings, navorsingsetiekkomitees, borge en deelnemers is ‘n integrale vereiste vir hierdie beskerming sowel as vir die verwerwing van nuwe, geldige en relevante wetenskaplike kennis.

Participation citoyenne et représentation démocratique dans les comités consultatifs

Décarie, Augustin 01 1900 (has links)
Selon les études en innovation démocratique, les comités consultatifs manqueraient généralement de représentativité et d’influence, ce qui en ferait des institutions participatives faibles. Pourtant, des milliers de citoyen·nes s’impliquent dans des comités consultatifs à travers le monde. Leur engagement est étonnant, car leur pouvoir politique et leur légitimité démocratique semblent considérablement limités. L’étude du cas des comités consultatifs des services aux élèves handicapés et en difficulté d’adaptation et d’apprentissage (comités EHDAA) permet de mieux comprendre pourquoi des citoyen·nes désirent s’impliquer dans de tels dispositifs imparfaits. Les comités EHDAA sont rattachés aux centres de services scolaires québécois et incluent une majorité de parents. Les parents des deux comités EHDAA étudiés font face à des contraintes importantes quant à leur légitimité démocratique et à leur influence. Ils trouvent quand même, à l’intérieur de ces comités, des occasions significatives de faire valoir les intérêts des élèves en situation de handicap ou de difficulté scolaire. La façon dont ils effectuent ce travail de représentation varie toutefois d’une personne à l’autre, selon les ressources qu’ils possèdent et leur attitude face aux limites démocratiques de leur comité. / According to studies on democratic innovations, advisory councils generally lack representativeness and influence, which makes them weak participatory institutions. However, thousands of citizens are involved in advisory councils around the world. Their participation is surprising because their political power and democratic legitimacy seem considerably limited. Studying the case of Advisory Committees on Special Education Services (ACSES) allows us to better understand why citizens get involved in such imperfect institutions. In Québec, ACSES are affiliated to school boards and include a majority of parents. The parents of the two ACSES studied face significant constraints regarding their democratic legitimacy and their influence. Nonetheless, they find within these institutions significant opportunities to advocate for the interests of students with disabilities and academic difficulties. Parents play their roles as representatives differently, depending on their resources and their attitudes towards the democratic limits of their committee.

Strategies to build the governance capacity of school governing bodies in previously disadvantaged communities

Mashele, Murray Elleck 08 1900 (has links)
In this study, a literature review and qualitative research design are used in an attempt to establish the obstacles to the effective governance of schools in previously disadvantaged communities. From the research, it emerges that the SGBs govern their schools intuitively. This is because they lack knowledge of how schools should be governed. Various strategies to build the governance capacity of these SGBs are formulated in this study to assist them to govern their schools effectively. Effective governance is an important instrument that can restore order, protect the rights of both learners and educators, prevent discipline problems amongst learners and establish the provision of quality education in these communities. / Teacher Education / M.Ed.

A study of the management attributes of excellent companies in Zimbabwe

Khumalo, Reinford 11 1900 (has links)
This study searches for the management attributes of excellent companies in Zimbabwe in order to reveal the management practices that have made these companies successful. Seven most successful companies from among those quoted on the Zimbabwean Stock Exchange (ZSE) were selected in terms of their financial criteria and the macroeconomic criteria in their industrial categories. The research for attributes of excellence has been qualitative - consisting mainly of interviews of chief executives, departmental managers, skilled, semi-skilled, and unskilled employees of the companies. The interviewees were also asked to complete two quantitative instruments: a semantic differential and an observation chart. Altogether 408 people were interviewed and given a semantic differential and an observation chart to complete. Of these, 398 responded to the semantic differential while 308 responded to the observation chart. Qualitative data for the study were content analysed and the data obtained through the quantitative instruments were analysed through the use of the Statistical Analysis Systems (SAS) at the Unisa Computer Services Centre. There was agreement in the results obtained through the use of the three different approaches of the research. The management attributes which were elicited by the study are that the Zimbabwean excellent companies : (a) have a participative style of management; (b) always engage in constant communication with all levels oftheir employees; (c) reward good work; (d) train their employees; (e) promote from within; (f) are concerned with the quality of their products and services; (g) care for customers; and (h) are involved in social responsibility. These management attributes can be applied by and could thus benefit any type of organisation, trading or non-trading, and private or public. The application of the attributes may not be limited to the enterprises in Zimbabwe - the host country in which the study was conducted - but it may also be effected in companies in other countries with a similar socioeconomic situation to Zimbabwe's. / Business Leadership / D.B.L.

The value of an audit committee at a high-growth potential, small to medium-sized listed company

La Grange, Madeleine 11 1900 (has links)
A company’s board of directors is ultimately responsible for putting effective corporate governance (CG) structures in place as mechanisms to enhance its accountability to stakeholders. An audit committee (AC), which is a subcommittee of the board, is one component of the company’s CG structures. In South Africa, legislation, the Johannesburg Stock Exchange (JSE) listing requirements, and the King code and report of Governance for South Africa 2009 (King III) deal with the composition and responsibilities of ACs. As the shares of AltX listed companies, which are categorised as high-growth potential, small to medium-sized listed companies, are traded publicly, they are required to comply with the Companies Act and to establish an AC according to the Act’s composition requirements to fulfil mandatory responsibilities. In terms of the JSE listing requirements, AltX listed companies must appoint an AC or explain their reason(s) for not doing so. As the total market capitalisation of AltX listed companies has increased by 87% over the past three years, greater numbers of stakeholder groups are being affected. Since stakeholder groups are protected when companies implement effective CG processes, the purpose of this study is to understand the way in which the AC of an AltX listed company, as an example of a high-growth potential, small to medium-sized listed company, adds value to the company and its stakeholders. Attributes that contribute to the value added by ACs were identified as being the characteristics of AC members; the fulfilment of responsibilities through optimised activities; and the fulfilment of responsibilities by maintaining healthy relationships with the board and information providers. An explorative qualitative case-based research design was applied in terms of which a single AltX listed company was selected according to predetermined selection criteria. Data were collected using individual semi-structured interviews, field notes and company documents. Descriptive open coding techniques were used for data analysis with the findings of the study subsequently being presented in terms of a theoretical framework of the attributes that influence the extent to which the AC adds value. The findings of the study confirm that these attributes of the AC facilitate its ability to add value to the AltX listed company investigated and its stakeholders in terms of enlightened shareholder theory. / Auditing / M.

Adopting the Public Accounts Committee Model for financial oversight in South African municipalities - a case study of the Public Accounts Committee in the City of Cape Town

Botes, Cobus 03 1900 (has links)
Thesis (MPA)--University of Stellenbosch, 2011. / Since its inception in 1861 when the first public accounts committee was established in the United Kingdom, this oversight mechanism has developed into a model for non-executive financial oversight and accountability at the national and provincial levels of government throughout the Commonwealth and beyond. A few municipalities in South Africa have also established public accounts committees, but they are a few isolated cases. The hesitance on the part of South African municipalities to establish a good governance mechanism with a proven track record is a cause of concern, especially in view of the poor financial management that prevails throughout the local sphere of government. In this case study of the public accounts committee established in the City of Cape Town in 2006, the researcher explores the feasibility of the implementation of the public accounts committee model within the local government sphere in South Africa. Twenty internationally recognised public accounts committee practices were identified and used to probe the selected case to gain in-depth knowledge of the extent to which the committee adheres to these recognised practices. Where the committee deviated from accepted practices, the reasons for the deviation and its impact on the effectiveness of the committee were analysed. Finally, the key lessons learnt from the experience of the public accounts committee in the City of Cape Town are used in order to make two sets of recommendations: Firstly, recommendations on how the public accounts committee of the City of Cape Town can become more effective than it currently is – recommendations which are also relevant to any municipality wishing to establish a public accounts committee. The second set of recommendations is addressed to the national authorities in charge of finance and local government, as the challenge of establishing improved governance systems in local government is of national importance, and it is within the power of these authorities to remove a few key obstacles in the way of establishing municipal public accounts committees.

L'impact du réseau de tramways sur la population marseillaise (fin XIXème-début XXème) / Impact of the tramway network on the population of Marseilles (end of 19th - beginning of 20th century)

Kokubu, Hisao 09 May 2011 (has links)
La période entre 1872 et 1931 correspondait à la phase maximale de l’urbanisation en France avant la Seconde Guerre mondiale. Les tramways jouaient un rôle décisif pour développer les banlieues. À Marseille, le premier maire socialiste Siméon Flaissières débuta dès le 1er janvier 1900 une politique du transport public urbain, introduisant l’électrification du réseau de tramways et surtout « les Tramways à dix centimes ». Le maire républicain et anti-collectiviste Amable Chanot prolongea ensuite des lignes du réseau, notamment vers les banlieues agricoles, sous la pression de l’opinion publique. L’installation du réseau de tramways dans les banlieues a influé sur le choix du domicile et le travail des individus et des familles. Jusqu’aux années 1920, les tramways étaient indispensables à la vie d’une grande ville. / The period between 1872 and 1931 was the time of greatest urbanization in France before the Second World War. The tramways played a determining role in the development of suburban residential areas. In Marseilles, from the 1st of January 1900, the first socialist Mayor, Siméon Flaissières instigated a policy of urban public transport, introducing the electrification of the tramway network, and most importantly, « The 10 Centimes Tramway » system. Giving in to the pressure of public opinion, the republican and anti-collectivist Mayor, Amable Chanot, later extended the network, especially towards the rural suburbs. The implementation of the suburban tramway network influenced the choices of places of residence and work of individuals and families alike. Up until the 1920’s, the tramways were an indispensable part of life in a big city.

Recherche clinique et "double standard éthique" dans les pays du Sud : enjeu des processus de discussion dans les prises de décisions collectives et individuelles / Clinical Resaerch and “double standard éthique” in developing countries : issues for discussion of process in collective and individual decision-making

Bereterbide, France 07 December 2011 (has links)
Nombre de « scandales éthiques » ont émaillé l’actualité de la recherche clinique dans les pays du Sud. Face à ce constat, il semble que les principes fondateurs de l’éthique de la recherche biomédicale admis et promulgués par les déclarations et les conférences de consensus internationales ne suffisent pas à protéger au Sud les volontaires participant à des essais cliniques. Nécessitant une adaptation hors du contexte qui a permis leur consolidation, bien que soit donné à voir à chaque nouveau scandale à quel point tout infléchissement des cadres normatifs peut être porteur de dérives inadmissibles, ces principes s’avèrent pour partie remis en question par la situation économique, sanitaire, sociétale des pays du Sud.Le concept de « double standard éthique » décrivant le double écueil auquel l’éthique de la recherche doit faire face, celle-ci s’avère captive d’une forme d’impérialisme des principes et des valeurs ou bien vouée au relativisme moral. La première alternative semble devoir conduire inexorablement à l’arrêt des recherches cliniques dans les pays ne permettant pas l’application stricte des normes qui les encadrent au Nord. La deuxième semble quant à elle mener à l’acceptation d’une réalisation irresponsable,dérégulée, d’essais cliniques aux finalités variables. Face à ce constat, se pose la question de savoir si cette alternative entre absolutisation de la norme et dérégulation peut être dépassée afin de penser une éthique de la recherche au Sud à la fois universelle et singulière.L’exploration de cette question permettra de redéfinir l’éthique comme processus de discussion et de priorisation des principes universels guidé par une compréhension de situations toujours singulières. De ce point de vue, l’adaptation des « conceptions internationalistes » de l’éthique de la recherche à la singularité des contextes apparaîtra non comme une nécessité externe, provoquée par un élément extérieur,mais comme un devoir inhérent à la nature même de la visée éthique. Plus encore, les questions posées par les contextes des pays du Sud à l’éthique de la recherche clinique serviront de révélateur en contribuant à montrer le bien fondé d’une remise encause des interprétations normatives de ses principes, au Nord y compris.7 / Number of “ethical scandals” have punctuated the news of clinical research in developing countries. Given this fact, it seems that the founding principles of the ethics’ biomedical research accepted and promulgated by declarations and international conferences are not enough to protect the volunteers participating in clinical trials in South’s countries. Out of context enabling their strengthening, ethical principles require adaptation. If each new scandal shows how any shift in regulatory frameworks may carry unacceptable abuses, these principles are nevertheless found challenged by South’s economic, state of health and social organizations. The concept of “double standard ethics” describes the twin dangers to which the biomedical research ethics faces. Indeed, biomedical research is captive to a form of imperialism of principles and values, or devoted to moral relativism. The first alternative seems to lead inexorably to the cessation of clinical research in developing countries do not allow the strict application of the standards that govern the North. The second appears to lead to the acceptance of irresponsible and unregulated clinical trials.Given this situation, the question arises whether this alternative may be exceeded in order to assume a research ethics in the South at once universal and unique. The exploration of this issue will redefine ethics as a process of discussion and priorization of universal principles guided by an understanding of situations always singular. From this point of view, the adaptation of “internationalist conceptions” of research ethics to unique contexts appear not as an external necessity but as a duty inherent in the nature of the ethical aim. Moreover, questions asked by the contexts of the South’s countries to the ethics’ clinical research will serve as a contributing developer to show the merits of a challenge to normative interpretations of its principles, including in North’s countries.

Essays on Allocation Procedures of Indivisibles / Sur les procédures d'allocation et de décision collective en présences d'indivisibilités

Aslan, Fatma 17 May 2019 (has links)
Cette thèse porte sur les mécanismes d’allocation de biens indivisibles en présence d’externalités dans les préférences individuelles. Ces externalités rendent difficile en pratique la collecte d’une information complète sur les préférences. Aussi, l’analyse normative des mécanismes d’allocation requiert de formuler des hypothèses sur la manière d’étendre l’information collectée aux préférences sur les allocations. Cette approche revient à définir des restrictions sur le domaine de préférences admissibles, une démarche bien connue de la théorie du choix social. Les trois premiers chapitres portent sur l’analyse du marché de Shapley-Scarf dans lequel les échanges sont organisés entre coalitions. Les chapitres 1 et 2 établissent des restrictions de domaine garantissant l’existence de différents types d’équilibre concurrentiel. Dans le chapitre 3, l’ensemble des biens est muni d’une géographie, ce qui permet de définir la distance entre partenaires comme source d’externalité. Nous identifions certains domaines de préférences qui assurent la non-vacuité de différents types de Coeur. Le chapitre 4 porte sur le cas de biens indivisibles publics purs. Nous montrons que le problème est formellement équivalent à celui du choix d’un comité dont les membres sont choisis dans des ensembles distincts. Nous caractérisons certains domaines de préférences sur les comités pour lesquels le choix majoritaire membre par membre est cohérent avec le choix majoritaire du comité dans son ensemble. / This thesis focuses on the allocation of indivisible goods in presence of externality in individual preferences. This externality creates a difficulty with collecting full information about preferences. Therefore, conducting a normative analysis of allocation mechanisms requires assumptions on how reported preferences can be extended to preferences over outcomes. This approach is in line with the literature on preference domain restriction well-known in Social Choice theory. The first three chapters focus on Shapley-Scarf markets where trades are organized among coalitions. Coalitional trade generates externalities in individual valuations of allocations. Chapters 1 and 2 investigate domain restrictions ensuring the existence of various types of competitive equilibrium. Chapter 3 endows the set of goods with a geographical structure and considers distance to partners as a source of externality in preference. We identify domains of preference extensions which guarantee the existence of various types of core allocations. Chapter 4 focuses the case of pure public indivisible goods, which is formally identical to choosing a committee formed by several members, each selected from a specific set. We characterize preference domains over committees for which a well-defined seat-wise choice procedure based on majority voting is consistent with choosing a committee at once from majority voting.

La protection des droits de l'homme en libye : garanties législatives et juridictionnelles (1969-2011) / The protection of human rights in Libya : legislative and judicial Warranty

Muftah, Abdusalam 10 December 2014 (has links)
En septembre 1969, un coup d’État mené par Kadhafi et ses compagnons donnera lieu à un modèle de gouvernement fondé sur la notion de la Jamahiriya qui trouve ses références théoriques dans le contenu du Livre Vert de Kadhafi. L’avènement de la Jamahiriya, qualifié de « Révolution », prétend mettre en œuvre l’exercice du pouvoir directement par le peuple (jamahir), à travers des congrès et des comités populaires. De fait, la première question qui se pose à nous est de cerner le type d’État en vigueur en Libye. Soulever ce point, c’est aussi s’interroger sur la place occupée par les droits de l’homme dans l’architecture institutionnelle libyenne. Et sous cet angle, l’idée qui s’impose est que l’organisation les droits et libertés relèvent de documents successifs : Déclaration de 1969 ; Charte verte des droits de 1988, loi de consolidation des libertés de 1991. Aussitôt surgit la question de la valeur juridique de ces textes dans la hiérarchie des normes, étant entendu qu’il n’existe pas en Libye une constitution proprement dite. C’est là une problématique essentielle, puisque de cette qualification dépend le degré de garantie des droits et libertés. On mesure alors l’importance d’une étude des principaux traits de la législation libyenne. Reste à ajouter que la reconnaissance des droits théoriquement affirmés, est tributaire de l’ordre « révolutionnaire » qui impose l’obligation de respecter et de protéger la Jamahiriya. Aborder ce point, c’est montrer les entraves que peut constituer le régime politique quant à la protection des Droits ; c’est également s’interroger sur le rôle du juge en tant que gardien des libertés. L’analyse de cet aspect implique une approche de l’étendue et des limites du contrôle des actes de l’État, qu’il soit un contrôle administratif ou un contrôle de constitutionnalité des lois, sachant que la combinaison de ces deux techniques sert en principe à offrir aux citoyens une garantie et l’assurance d’exercer pleinement leurs droits et libertés. Or, là encore, les moyens juridictionnels conçus pour assurer la protection des droits fondamentaux risquent de se heurter à la nature du régime qui met en avant la protection de la « révolution » au dépend de toute autre liberté. C’est autrement soutenir que le système institutionnel dans son entier constitue une restriction à la protection des Droits. Évoquer cette réalité, c’est éclairer les entraves relevant de la pratique même du pouvoir. En définitive, la nature du régime et l’idéologie de la Jamahiriya conditionnent la forme d’expression des droits fondamentaux. C’est là tout l’enjeu du rapport entre pouvoir et libertés publiques que nous proposons d’étudier dans le cadre de ce travail. / In September 1969, a coup led by Gaddafi and his companions will result in a model of government based on the concept of the Republic which finds it’s theoretical references in the content of the Green Book of Gaddafi. The advent of the Republic, also called "Revolution", claimed to implement the exercise of power by the people (Jamahir) through congresses and people's committees. In fact, the first question that faces us is to identify the type of state force in Libya. Raising this point is also questioning the place of human rights in Libya's institutional architecture. And in this light, the idea must be that the organizations of human rights and freedoms are relieving from successive documents: Declaration of 1969; Green Charter of Human Rights of 1988, Freedoms Consolidation Act 1991. Soon after arose the question of the legal status of these texts in the hierarchy of norms, provided there is no constitution in Libya itself. This is a key issue, since from this qualification depend the degree of guarantee of rights and freedoms. The importance of a study of the main features of Libyan legislation is measured. It remains to add that the recognition of the rights affirmed in theory, depends on the order "revolutionary" which imposes the obligation to respect and protect the Republic. Address this point is to show the obstacles that may be the political regime on the protection of rights; it is also questioning the judge's role as a guardian of freedom. The analysis of this aspect involves an approach to the scope and limitations of the control of state action, whether administrative supervision or control of the constitutionality of laws, knowing that the combination of these two techniques are used in principle to provide citizens with a warranty and insurance to fully exercise their rights and freedoms. Yet again, the judicial remedies designed to ensure the protection of human rights are likely to face the kind of diet that emphasizes the protection of the "revolution" at the expense of all other freedoms. It is in another way to support that the institutional system as a whole constitutes a restriction on the Protection of the Rights. Discussing this reality is exposing the barriers within the same practice of power. Ultimately, the nature of the regime and the ideology of the Libyan determine the form of expression of fundamental rights. That's the whole point of the relationship between public power and freedoms that we propose to study in the context of this work.
