Malgré les nombreuses approches envisagées à ce jour, la dynamique du stress microbien en conditions de culture intensive (procédé fed-batch) est encore un aspect mal maîtrisé. Au cours de ce travail, deux biocapteurs microbiens basés sur le principe de la protéine fluorescente verte (Green Fluorescent Protein ou GFP) ont été mis en œuvre dans des réacteurs scale-down permettant de reproduire les défauts d'écoulement rencontrés dans les bioréacteurs industriels. Les promoteurs de stress associés à la synthèse de la GFP ont été choisis suivant leur sensibilité à la limitation en source de carbone, condition standard qui est rencontrée dans les processus fed-batch ou l'apport en substrat carboné est limité afin d'éviter des déviations du métabolisme microbien (promoteurs rpoS et csiE). Les résultats obtenus montrent clairement que l'exposition des biocapteurs à des hétérogénéités locales de substrat entraîne une diminution de l'expression de la GFP. L'intensité de fluorescence a été mesurée à l'échelle cellulaire par cytométrie en flux. Durant les cultures, une chute significative du niveau de GFP intracellulaire a été observée pour les deux conditions scale-down considérées et pour les deux types de promoteur. Cette chute de fluorescence peut être attribuée à des phénomènes de répression des promoteurs suite à la levée locale de la limitation en carbone, mais également au relargage de la GFP dans le milieu extracellulaire. Ce relargage a été observé dans toutes les conditions opératoires considérées, comme le montrent les analyses des surnageants de culture par SDS-PAGE. L'intensité du relargage est néanmoins plus forte dans les conditions standard de culture (c'est-à-dire dans des réacteurs classiques sans approche scale-down). En effet, la coloration par l'iodure de propidium des biocapteurs cultivés en conditions standards est plus élevée que dans les conditions scale-down, suggérant une perméabilité membranaire plus élevée. Ces résultats offrent des potentialités intéressantes pour l'analyse simultanée de la viabilité cellulaire et de la détection des défauts d'écoulement par l'emploi de biocapteurs microbiens. De plus, les analyses par SDS-PAGE ont montre une grande diversité de protéines relargée en cours de procédé. Cette observation est étonnante du fait de l'emploi de milieux minéraux définis dans toutes les conditions étudiées. L'analyse de ce sécrétome offre des potentialités intéressantes pour la caractérisation des conditions de stress encourues par les micro-organismes au cours des procédés. [less ▲]

Today, in the Belgian context, prison governors are working in organisations characterized by legislative and managerial reforms which are based on new discourses (NPM, Human Rights, Restorative justice, Sustainable development, Risk management, etc.), new laws (2005 and 2007 prison acts) and new tools (KPI, Management plans, Balanced scoreboard, etc.). Rarely studied, prison governors can be seen as intermediary actors occupying both the highest hierarchical position at the organisational level and a subordinate one vis-à-vis the central administration (the Prison Service and its federal and regional directions). They also fulfil a role that makes them responsible for more than 11,000 inmates and 9,000 employees. While some experts write that prison policies are rare or non-existent (and Lascoumes Artières, 2004; Mary, 2006), how can we account for prison governance, emerging and largely informal, allowing Belgian prisons to run despite the internal and external tensions and pressures, coming from inmates, guards, civil and political society? This presentation is based on 60 semi-structured interviews conducted with prison governors (N=30) and various prison professionals (N=30). It aims at depicting governors’ concrete practices and interactions in order to account for their work as middle managers and policy makers. [less ▲]

Considering their intermediary position between central policy and local practices, but also the impact of new discourses and knowledge on their profession (Abbott, 1988; Freidson, 2001), this presentation will focus on prison governors’ work. This research strategy aims at posing a de-centred glance on the policy and organizational processes through which new discourses related to New Public Management [NPM] are translated (Callon, 1986) within Belgian prisons. The focus will be put on the devices and local practices through which NPM discourses are translated and (re)shape prison governors’ profession. [less ▲]

L’actualité médiatique de ces derniers mois a relaté plusieurs cas de désordres survenus dans nos prisons : actes de violence, grève du personnel, évasions, suicides, mutineries, etc. Derrière ces indicateurs de crise, on peut également déceler les traces, de plus en plus nombreuses, d’un vaste chantier de modernisation dans lequel l’administration pénitentiaire s’est engagée, comme l’indiquent le plan de management initié par le directeur général, la reconfiguration de la profession de directeur ou encore l’introduction de notions managériales dans les discours de ces derniers. Les expériences anglaises et néerlandaises offrent une perspective décentrée pour saisir les opportunités de changement que permettent (ou non) les crises et le Nouveau Management Public. Nous proposons ici de nous inspirer de ces expériences pour en extraire quelques pistes de réflexion à propos de notre administration pénitentiaire. [less ▲]

Molecular technologies have shown unequivocally that much of Antarctica’s biological value and diversity lies in its microbiota. Microbial diversity varies greatly over small spatial scales, and there may be high levels of endemism in some groups. At the 2012 SCAR Open Science Conference, .70% of scientific presentations by terrestrial biologists concerned microbiology, and the topic features prominently in the newly approved SCAR biology programmes State of the Antarctic Ecosystem (AntEco) and Antarctic Thresholds - Ecosystem Resilience and Adaptation (AnT-ERA). The future looks bright for Antarctic microbiology - but some significant threats need to be addressed and resolved. [less ▲]

Family law has undergone a radical change over the last twenty years or so. While marriage previously dominated the field, leaving very little room for non-married couples, whose situation was mainly characterised by the absence of firm legal principles, the recent decades have seen the rise of new legal institutions affording a measure of legal protection to couples outside marriage. This has coincided with the desire to ensure that same-sex couples could find a place within the law. As a result, the landscape of family law has profoundly changed. If one examines the current stand of the law, it becomes clear that following this evolution, a few common points stand out while substantial differences remain. Whereas a large number of countries have created the possibility to register unions different from marriage, not all of them have done so. Some countries have shown indifference to the idea, other have demonstrated clear reluctance, sometimes even outright rejection. Among the countries which have created 'partnerships' and other new forms of relationships, the diversity is obvious, with some countries offering a close copy of the marriage, while other have opted for a less favourable regime. Finally, a handful of countries have opened up the possibility of marriage to same-sex partners. From the outset this evolution has been closely studied from the private international law perspective. In view of the ever increasing mobility of persons within the EU and beyond the conflict of laws treatment of same-sex marriages and partnerships is indeed far from a purely theoretical concern. The cross-border aspects of these relations have already been documented in a number of fundamental studies. Some years down the road, it appears useful to pause and wonder whether the difficulties and problems uncovered in these studies have been resolved. To this end, this paper intends to offer a general review of the private international law of same-sex relationships, focusing on the situation in Member States of the European Union. Because of the number of countries whose laws will be examined, we intend to adopt a bottom-up approach, starting not so much from general questions and problems, but rather from a close examination of the private international law rules pertaining to same-sex relationships (marriages and partnerships) in Europe. From this examination it will be possible to determine whether and on what issues there exists a consensus among the countries concerned on the treatment of same-sex relationships. This will be done by looking first at the possibility for same-sex partners to access a specific status. In a second stage, the enquiry will focus on the consequences arising out of a particular status. From there the paper intends to identify the difficulties arising out of the lack of consensus. In a final chapter, some thoughts will be offered on the way forward – in particular assessing the merits of a global or European solution to tackle cross-border recognition problems. [less ▲]

In Benin, like in many countries in sub-Saharan Africa, the setting up of structural adjustment programs forces, in the middle of eighties, the government to limit the recruitment in civil service. As they were systematically hired by the State, most of health professionals are unemployed from 1986. Henceforth, private health sector grow progressively, without any legislation, through the development of many formal and informal private surgeries and clinics. The article will focus mainly on the development of private profit-making medical practice in Benin. It will be based on three empirical researches about medical profession in this country, from March 2009 to April 2011. In this paper, we will refer to qualitative interviews on the one hand with actors from both private and public medical structures, mainly doctors, paramedical staffs and patients, and one the other hand, with representatives of professional organizations, public policies in Ministry of Health and international organizations. First, the article will briefly describe the historical development of private medical practice in Benin, and consider governmental responses to this process. Thus we will address to the belated drawing up of a regulatory framework and the lack of control by the profession consequences, notably in terms of qualification, ethics and quality of health care. We will also examine recent reactions aimed at remedying to these different pitfalls. In this context, the paper will interest secondly in new entanglements between the public medical sector and the private medical structures emerging at local level. We will examine doctors’ practices and strategies, with only private practitioners and with doctors working in both private and public sectors. Finally, the article will give attention to how these private medical surgeries and clinics and the access conditions to these structures are perceived by health providers and patients. In this part of the paper, we will also address to tactics worked by patients regarding the different medical facilities. As a conclusion, we will wonder whether this medical private sector would contribute to reproduce some mechanisms of inequality in health sector. [less ▲]

In 1990, Lambotte syndrome was reported as an apparently autosomal recessive multiple congenital anomaly/mental retardation (MCA/MR) syndrome observed in 4 of 12 sibs from a probably consanguineous mating [Verloes et al., Am J Med Genet 1990; 37:119-123]. Major manifestations included intrauterine growth retardation (IUGR), microcephaly, large soft pinnae, hypertelorism, beaked nose, and extremely severe neurologic impairment, with holoprosencephaly in one instance. After the observation of a further affected child born of one unaffected sister, in situ hybridization analysis and chromosome painting techniques demonstrated a subtle t(2;4)(q37.1; p16.2) translocation in the mother, suggesting a combination of 2q/4p trisomy/monosomy in all of the affected children of the family. Many private sporadic or recurrent MCA/MR syndromes maybe due to similar symmetric translocations, undetectable by conventional banding techniques. [less ▲]
