Holy harlots : authority, gender, and the body in medieval English hagiography

This doctoral dissertation aims at describing the representation of holy harlots (Mary Magdalene, Mary of Egypt, Pelagia, Thai's, Afra of Augsburg) in medieval English hagiography. These saints are unique representatives that combine both extremes of the feminine in the medieval imaginaire: she is both, as a saint, the Virgin Mary, the pure and virtuous woman, and, in her past as a prostitute, Eve, the evil female tempter who led all mankind to destruction. The initial question of this thesis is how did hagiographers negotiate the representation of a formerly sinful, sexually active, long- living woman as an authoritative saint? This thesis aims at finding elements of answer to this question, investigating the intersections between gender and authority in the saints' lives of repentant prostitutes in all the vernaculars of medieval England: Old English, Anglo-Norman, and Middle English. It posits that the portrayal of holy harlots' authority and gender is dependent upon social, religious and literary shifts during the medieval period. My contention is that the harlot's gender portrayal changes over the course of the eleventh and twelfth centuries, due notably to the rise of affective piety and the important influence of the romance genre over hagiography. In Anglo-Saxon England, the harlot's gender changes with the saint's conversion: a woman beforehand, her gender is portrayed after her repentance as ambiguous in order for her to become a saint. Her authority derives from her own sanctity in this case. From the twelfth century onward, however, the harlot, now often turned into a beautiful and landed romance lady, is more and more represented as a woman throughout her life, and becomes after her conversion a Bride of Christ. In this way, the dangerously free woman who roamed the streets and prostituted her body becomes less threatening after her conversion, being (re-)inscribed within the male dominated institution of marriage. She now draws her authoritative stance from her gendered intimacy with Christ: although she submits to Christ as his bride, she also gains greater authority than before by way of her privileged relationship with the Savior.

Ageing-related cardiomyocyte functional decline is sex and angiotensin II dependent.

Clinically, heart failure is an age-dependent pathological phenomenon and displays sex-specific characteristics. The renin-angiotensin system mediates cardiac pathology in heart failure. This study investigated the sexually dimorphic functional effects of ageing combined with angiotensin II (AngII) on cardiac muscle cell function, twitch and Ca(2+)-handling characteristics of isolated cardiomyocytes from young (~13 weeks) and aged (~87 weeks) adult wild type (WT) and AngII-transgenic (TG) mice. We hypothesised that AngII-induced contractile impairment would be exacerbated in aged female cardiomyocytes and linked to Ca(2+)-handling disturbances. AngII-induced cardiomyocyte hypertrophy was evident in young adult mice of both sexes and accentuated by age (aged adult ~21-23 % increases in cell length relative to WT). In female AngII-TG mice, ageing was associated with suppressed cardiomyocyte contractility (% shortening, maximum rate of shortening, maximum rate of relaxation). This was associated with delayed cytosolic Ca(2+) removal during twitch relaxation (Tau ~20 % increase relative to young adult female WT), and myofilament responsiveness to Ca(2+) was maintained. In contrast, aged AngII-TG male cardiomyocytes exhibited peak shortening equivalent to young TG; yet, myofilament Ca(2+) responsiveness was profoundly reduced with ageing. Increased pro-arrhythmogenic spontaneous activity was evident with age and cardiac AngII overexpression in male mice (42-55 % of myocytes) but relatively suppressed in female aged transgenic mice. Female myocytes with elevated AngII appear more susceptible to an age-related contractile deficit, whereas male AngII-TG myocytes preserve contractile function with age but exhibit desensitisation of myofilaments to Ca(2+) and a heightened vulnerability to arrhythmic activity. These findings support the contention that sex-specific therapies are required for the treatment of age-progressive heart failure.

Quand les normes font loi : topologie intégrée et processus différenciés de la normalisation internationale

International standardisation refers to voluntary technical specifications pertaining to the production and exchange of goods and services across borders. The paper outlines a theoretical framework which spells out the contention of emerging hybrid forms of non state authority in the global realm. It argues that international standardisation is confronted with a deep rift between promoters of further socialisation of international standards (i.e. a transfer of the universal scope of law into the official framework of standard-setting bodies) and multinational corporations in favour of globalisation of technical standards (i.e. universal recognition of minimal sectorial market-based standards). The problems related to the development of a possible ISO standard of system management in corporate social responsibility provides evidence of the argument.

Cardiovascular patterns associated with appetitive and defensive activation during affective picture viewing

Descriptors: cardiovascular patterns, emotion, affective pictures In this study we assessed blood pressure (BP), heart rate (HR), stroke volume (SV), cardiac output (CO), and total peripheral resistance (TPR) in response to 13 picture series in 18 men and 19 women in order to investigate their hemodynamic responses associated with activation of the appetitive and defensive motivational systems underlying emotional experience. Skin conductance level (SCL) was also recorded. BP and SV increased with increasing self-rated arousal both for appetitive and defensive activation, whereas HR decelerated more in response to negative than positive and neutral pictures. TPR showed a general increase from baseline to picture processing but was unrelated to self-rated valence and arousal. These findings suggest that affective modulation of the cardiovascular response to affective pictures is primarily myocardial. The observed response pattern is consistent with a configuration of cardiac sympathetic-parasympathetic coactivation. The relationships between self-reported arousal, BP and SV were mainly exhibited by men suggesting that increases in the sympathetic inotropic effect to the heart with increasing self-rated arousal might be larger in men than in women. In contrast, SCL covaried positively with self-rated arousal both in men and women. This suggests that sex differences in the affective modulation of the responses to pictures may be restricted to specific cardiovascular parameters and support the contention that the sympathetic nervous system does not discharge as a whole.

Effect of oral calcium carbonate on aortic calcification in apolipoprotein E-deficient (apoE-/-) mice with chronic renal failure.

BACKGROUND: In chronic kidney disease (CKD) patients, the intake of calcium-based phosphate binders is associated with a marked progression of coronary artery and aortic calcification, in contrast to patients receiving calcium-free phosphate binders. The aim of this study was to reexamine the role of calcium carbonate in vascular calcification and to analyse its effect on aortic calcification-related gene expression in chronic renal failure (CRF). METHODS: Mice deficient in apolipoprotein E underwent either sham operation or subtotal nephrectomy to create CRF. They were then randomly assigned to one of the three following groups: a control non-CRF group and a CRF group fed on standard diet, and a CRF group fed on calcium carbonate enriched diet, for a period of 8 weeks. Aortic atherosclerotic plaque and calcification were evaluated using quantitative morphologic image processing. Aortic gene and protein expression was examined using immunohistochemistry and Q-PCR methods. RESULTS: Calcium carbonate supplementation was effective in decreasing serum phosphorus but was associated with a higher serum calcium concentration. Compared with standard diet, calcium carbonate enriched diet unexpectedly induced a significant decrease of both plaque (p<0.05) and non-plaque-associated calcification surface (p<0.05) in CRF mice. It also increased osteopontin (OPN) protein expression in atherosclerotic lesion areas of aortic root. There was also a numerical increase in OPN and osteoprotegerin gene expression in total thoracic aorta but the difference did not reach the level of significance. Finally, calcium carbonate did not change the severity of atherosclerotic lesions. CONCLUSION: In this experimental model of CRF, calcium carbonate supplementation did not accelerate but instead decreased vascular calcification. If our observation can be extrapolated to humans, it appears to question the contention that calcium carbonate supplementation, at least when given in moderate amounts, necessarily enhances vascular calcification. It is also compatible with the hypothesis of a preponderant role of phosphorus over that of calcium in promoting vascular calcification in CRF.

Leadership in cardiac surgery.

Despite the efficacy of cardiac surgery, less invasive interventions with more uncertain long-term outcomes are increasingly challenging surgery as first-line treatment for several congenital, degenerative and ischemic cardiac diseases. The specialty must evolve if it is to ensure its future relevance. More importantly, it must evolve to ensure that future patients have access to treatments with proven long-term effectiveness. This cannot be achieved without dynamic leadership; however, our contention is that this is not enough. The demands of a modern surgical career and the importance of the task at hand are such that the serendipitous emergence of traditional charismatic leadership cannot be relied upon to deliver necessary change. We advocate systematic analysis and strategic leadership at a local, national and international level in four key areas: Clinical Care, Research, Education and Training, and Stakeholder Engagement. While we anticipate that exceptional individuals will continue to shape the future of our specialty, the creation of robust structures to deliver collective leadership in these key areas is of paramount importance.

L'apport de CoLaus en santé publique. [What CoLaus has brought to Public health].

Afin de mener à bien leur tâche, les acteurs de santé publique se doivent de disposer d'informations fiables et récentes concernant l'état de santé de la population. Grâce à l'étude CoLaus, il a été possible d'actualiser nos connaissances sur la prévalence et la prise en charge des principaux facteurs de risque cardiovasculaire au niveau de la population lausannoise. Les résultats montrent que la prise en charge des facteurs de risque cardiovasculaire peut être améliorée, et certaines strates de la population pourraient bénéficier d'actions de prévention ciblées. L'étude CoLaus a aussi permis de simuler l'effet de plusieurs politiques de prévention, ce qui permettra de sélectionner celles ayant le meilleur rapport coût/efficacité, une option importante dans l'état actuel de contention des dépenses de santé.[Abstract] In order to fulfil their duties, Public health authorities have to rely on valid and recent data on the health status of populations. The CoLaus study helped to update our knowledge regarding the prevalence and management of the main cardiovascular risk factors in the Lausanne population. The results indicate that cardiovascular risk factor management is suboptimal and can still be improved, namely that specific population subgroups could benefit from targeted prevention measures. The CoLaus study also allowed to simulate the effect of different preventive strategies, thus enabling to choose the most (cost)effective ones, an important issue taking into account the current health budget restrictions.

Analysis by confocal microscopy of the behavior of heat shock protein 70 within the nucleus and of a nuclear matrix polypeptide during prolonged heat shock response in HeLa cells.

By means of confocal laser scanning microscopy and indirect fluorescence experiments we have examined the behavior of heat-shock protein 70 (HSP70) within the nucleus as well as of a nuclear matrix protein (M(r) = 125 kDa) during a prolonged heat-shock response (up to 24 h at 42 degrees C) in HeLa cells. In control cells HSP70 was mainly located in the cytoplasm. The protein translocated within the nucleus upon cell exposure to hyperthermia. The fluorescent pattern revealed by monoclonal antibody to HSP70 exhibited several changes during the 24-h-long incubation. The nuclear matrix protein showed changes in its location that were evident as early as 1 h after initiation of heat shock. After 7 h of treatment, the protein regained its original distribution. However, in the late stages of the hyperthermic treatment (17-24 h) the fluorescent pattern due to 125-kDa protein changed again and its original distribution was never observed again. These results show that HSP70 changes its localization within the nucleus conceivably because it is involved in solubilizing aggregated polypeptides present in different nuclear regions. Our data also strengthen the contention that proteins of the insoluble nucleoskeleton are involved in nuclear structure changes that occur during heat-shock response.

The political ecology of weeds : a scalar approach to landscape transformations

How do plants that move and spread across landscapes become branded as weeds and thereby objects of contention and control? We outline a political ecology approach that builds on a Lefebvrian understanding of the production of space, identifying three scalar moments that make plants into 'weeds' in different spatial contexts and landscapes. The three moments are: the operational scale, which relates to empirical phenomena in nature and society; the observational scale, which defines formal concepts of these phenomena and their implicit or explicit 'biopower' across institutional and spatial categories; and the interpretive scale, which is communicated through stories and actions expressing human feelings or concerns regarding the phenomena and processes of socio-spatial change. Together, these three scalar moments interact to produce a political ecology of landscape transformation, where biophysical and socio-cultural processes of daily life encounter formal categories and modes of control as well as emotive and normative expectations in shaping landscapes. Using three exemplar 'weeds' - acacia, lantana and ambrosia - our political ecology approach to landscape transformations shows that weeds do not act alone and that invasives are not inherently bad organisms. Humans and weeds go together; plants take advantage of spaces and opportunities that we create. Human desires for preserving certain social values in landscapes in contradiction to actual transformations is often at the heart of definitions of and conflicts over weeds or invasives.

Les artistes visuels au Yémen, du soutien à la contestation de l'ordre politique

Cette thèse appréhende les rapports au politique des artistes visuels yéménites dans un contexte de domination, recouvrant trois États (les deux républiques qui précédent l'unification du Yémen et la république actuelle créée en 1990, jusqu'en 2015). En étudiant la domination en acte à travers une démarche ethnographique, ce travail interroge les conditions de production et d'action des artistes en soutien ou en contestation au régime, comme au cours du moment révolutionnaire de 2011. On observe ainsi le processus de politisation des mondes de l'art au Yémen contemporain, processus compris en tant qu'acquisition d'une signification politique par la pratique artistique et par les réseaux de relations entretenus par les artistes visuels. Ces requalifications de leur travail ou de leurs actions se font dans un contexte traversé par des luttes concurrentielles pour la répartition du pouvoir, aussi bien internes et propres à leurs mondes d'activité, qu'externes et en relation à l'espace politique institutionnel. La politisation des mondes de l'art apparaît dès lors moins comme un instrument d'accès à cet espace qu'une voie pour accéder à plus de visibilité, à la reconnaissance, et à un meilleur positionnement dans les rapports agonistiques qui configurent ces mondes. -- This thesis focuses on the study of Yemeni visual artists' relation to politics in a context of domination, covering three States (the two republics that precede Yemen's unification and the current republic established in 1990, until 2015). Studying domination in action througli an ethnographic approach, this work questions artists' conditions of production and of action in support to or in contestation of the regime- as in the case of the revolutionary period of 2011. It observes the politicization of art worlds in contemporary Yemen, a process understood as the acquisition of a political significance as observed in the artistic practice and in the dynamic networks that artists maintain. The requalification and reclassification of their work and their actions that results from the politicization of art worlds, takes place in a context of competitive struggles over distribution and access to sites of power. Such conflict over power occurs within their own worlds of activity as well as outside them and in relation to the domain of institutional politics. This thesis contends that the politicization of art worlds is more of a means to access visibility and recognition than a resource to participate in the political field. Through the politicization of art, artists are able to better position themselves within the agonistic relations that exist within art worlds.
