Mainmise sur l'état social : mobilisation patronale et caisse de compensation en Suisse (1908-1960)

Qui sait qu'en Suisse, les associations patronales mettent en oeuvre l'Etat social ? Qui sait que associations organisent la majorité des caisses de compensation, dont la fonction principale est de collecter les cotisations et de payer les rentes de l'Assurance-vieillesse et survivants ? Qui connaît ces caisses par lesquelles transitent les milliards de l'Etat social ? L'objectif de cette thèse consiste à comprendre les raisons qui ont poussé le patronat helvétique à mettre en oeuvre les politiques de protection sociale, dont il a pourtant toujours essayé de limiter le développement. Résoudre ce paradoxe implique de se pencher sur près d'un siècle d'histoire mêlée du patronat et des politiques sociales. Ce travail retrace, sur la base d'archives privées et publiques souvent inédites, les raisons qui ont poussé les patrons à créer les premières caisses de compensation dans l'entre-deux-guerres, puis à imposer cette forme d'organisation pour l'aide aux soldats mobilisés (autour de 1940) et l'Assurance- vieillesse et survivants (autour de 1948). Il étudie également comment les associations patronales sont parvenues à défendre leurs caisses jusqu'à aujourd'hui, contre ceux qui dénonçaient l'irrationalité de l'existence d'une centaine de caisses de compensation publiques et privées concurrentes pour mettre en oeuvre un seul système d'assurances sociales. Cette recherche amène deux grands résultats. D'une part, elle propose une histoire originale des politiques sociales en Suisse. Le prisme des caisses de compensation patronales contribue en effet à interroger notre compréhension de l'histoire des politiques de protection sociale, dans laquelle on sous-estime parfois l'importance des conflits pour fixer les frontières entre formes de protection publique et privée. D'autre part, ce travail présente une histoire inédite de l'action collective des patrons dans les régulations du travail au sens large. A travers les caisses de compensation, c'est en effet à réaliser une histoire de l'Union centrale des associations patronales suisses que je me suis aussi attelé. Faute de parvenir à empêcher tout développement des politiques sociales, les patrons ont fait en sorte d'acquérir sur ces politiques une forme de mainmise. Entre histoire des politiques sociales et histoire du patronat, ce travail tente d'expliquer comment les caisses de compensation y ont contribué. Who knows that, in Switzerland, employers' associations implement the best known policies constituting the welfare state? Who knows that the equalization funds, (Caisses de compensation / Ausgleichskassen), organized by employers' associations or by the Swiss Cantons, are responsible for pooling payroll deductions and for paying benefits of the Swiss public pay-as-you-go, old-age insurance and many other branches of the welfare policies? Who knows these caisses de compensation that channel the monies dedicated to the financing of the Welfare state ? The main objective of this research is to understand the reasons why Swiss employers do implement such welfare policies that they usually reject for political reasons. In order to solve this puzzle, this research investigates half of a century of the connected histories of welfare policies and employers' collective action. It also investigates, based on public and private archive records, how employers founded the first caisses in the Interwar period, and imposed them to organize the main developments of the Welfare state during the Second World War. The research also underlines how employers defended their caisses de compensation against those questioning the rationality of this fragmented system aiming to implement one single set of public welfare through one hundred competing private and public caisses de compensation. This research highlights two main results. On the one hand, it helps to improve our understanding of the history of the welfare policies in Switzerland. Underlining the role of the caisses de compensation helps to highlight the importance of the interplay of public and private actors regarding social polices. On the other hand, this research charts a pioneering history of Swiss' employers' collective action regarding labor issues. Because they could not prevent all public welfare policy, employers achieved a form of stranglehold (mainmise) on the welfare State. Halfway between social policy and employers' associations' history, this research try to reveal how their caisses de compensation helped them in this objective.

Compensation for environmental damages under international law

ABSTRACT The purpose of this research is to clarify the contribution of international dispute adjudication mechanisms in regard to environmental protection. Most specifically, the study aims to identify and develop the criterion adopted by the international judge in relation to the compensation for environmental damages. In this perspective, the study identifies some gaps between international responsibility and environmental protection interests. The premise sustained all along the study is that compensation is determinant to conciliate environmental prerogatives with mechanisms of international adjudication, in particular the system of international responsibility. Supported by the analysis of treaties, international decisions and secondary sources, the thesis defends the idea that some elements of international law allow the adjudicator to adapt the compensation to attend certain environmental interests, creating a new approach which was entitled 'fair compensation'. The antithesis of this approach is the idea that compensation in international law is limited exclusively to the strict reparation of the material losses incurred by the victim. As a synthesis, the study defends the specificity of environmental damages in relation to other kind of damages that are subject to compensation under international law. The measure upon which compensation for environmental damages could be classified as a specific type of damage under international law remains to be determined. The main conclusion of the study is that the existing standard of compensation defined by the theory and practice of international law is impossible to be strictly respected in cases involving environmental damages. This limitation is mainly due to the complexity of the notion of environment, which is constantly conflicting with the anthropologic view of legal theory. The study supports the idea that the establishment of a 'fair compensation' which takes into account the political, legal and technical context of the environmental damage, is the best possible approach to conciliate internationally responsibility and environmental interests. This could be implemented by the observance of certain elements by the international judge/arbitrator through a case-by-case analysis.

Living with an imperfect cell wall: compensation of femAB inactivation in Staphylococcus aureus.

BACKGROUND: Synthesis of the Staphylococcus aureus peptidoglycan pentaglycine interpeptide bridge is catalyzed by the nonribosomal peptidyl transferases FemX, FemA and FemB. Inactivation of the femAB operon reduces the interpeptide to a monoglycine, leading to a poorly crosslinked peptidoglycan. femAB mutants show a reduced growth rate and are hypersusceptible to virtually all antibiotics, including methicillin, making FemAB a potential target to restore beta-lactam susceptibility in methicillin-resistant S. aureus (MRSA). Cis-complementation with wild type femAB only restores synthesis of the pentaglycine interpeptide and methicillin resistance, but the growth rate remains low. This study characterizes the adaptations that ensured survival of the cells after femAB inactivation. RESULTS: In addition to slow growth, the cis-complemented femAB mutant showed temperature sensitivity and a higher methicillin resistance than the wild type. Transcriptional profiling paired with reporter metabolite analysis revealed multiple changes in the global transcriptome. A number of transporters for sugars, glycerol, and glycine betaine, some of which could serve as osmoprotectants, were upregulated. Striking differences were found in the transcription of several genes involved in nitrogen metabolism and the arginine-deiminase pathway, an alternative for ATP production. In addition, microarray data indicated enhanced expression of virulence factors that correlated with premature expression of the global regulators sae, sarA, and agr. CONCLUSION: Survival under conditions preventing normal cell wall formation triggered complex adaptations that incurred a fitness cost, showing the remarkable flexibility of S. aureus to circumvent cell wall damage. Potential FemAB inhibitors would have to be used in combination with other antibiotics to prevent selection of resistant survivors.

Predicting trabecular bone microdamage initiation and accumulation using a non-linear perfect damage model

Studies evaluating the mechanical behavior of the trabecular microstructure play an important role in our understanding of pathologies such as osteoporosis, and in increasing our understanding of bone fracture and bone adaptation. Understanding of such behavior in bone is important for predicting and providing early treatment of fractures. The objective of this study is to present a numerical model for studying the initiation and accumulation of trabecular bone microdamage in both the pre- and post-yield regions. A sub-region of human vertebral trabecular bone was analyzed using a uniformly loaded anatomically accurate microstructural three-dimensional finite element model. The evolution of trabecular bone microdamage was governed using a non-linear, modulus reduction, perfect damage approach derived from a generalized plasticity stress-strain law. The model introduced in this paper establishes a history of microdamage evolution in both the pre- and post-yield regions

A peptide inhibitor of C-jun N-terminal kinase modulates hepatic damage and the inflammatory response after hemorrhagic shock and resuscitation

Hemorrhage and resuscitation (H/R) leads to phosphorylation of mitogen-activated stress kinases, an event that is associated with organ damage. Recently, a specific, cell-penetrating, protease-resistant inhibitory peptide of the mitogen-activated protein kinase c-JUN N-terminal kinase (JNK) was developed (D-JNKI-1). Here, using this peptide, we tested if inhibition of JNK protects against organ damage after H/R. Male Sprague-Dawley rats were treated with D-JNKI-1 (11 mg/kg, i.p.) or vehicle. Thirty minutes later, rats were hemorrhaged for 1 h to a MAP of 30 to 35 mmHg and then resuscitated with 60% of the shed blood and twice the shed blood volume as Ringer lactate. Tissues were harvested 2 h later. ANOVA with Tukey post hoc analysis or Kruskal-Wallis ANOVA on ranks, P < 0.05, was considered significant. c-JUN N-terminal kinase inhibition decreased serum alanine aminotransferase activity as a marker of liver injury by 70%, serum creatine kinase activity by 67%, and serum lactate dehydrogenase activity by 60% as compared with vehicle treatment. The histological tissue damage observed was blunted after D-JNKI-1 pretreatment both for necrotic and apoptotic cell death. Hepatic leukocyte infiltration and serum IL-6 levels were largely diminished after D-JNKI-1 pretreatment. The extent of oxidative stress as evaluated by immunohistochemical detection of 4-hydroxynonenal was largely abrogated after JNK inhibition. After JNK inhibition, activation of cJUN after H/R was also reduced. Hemorrhage and resuscitation induces a systemic inflammatory response and leads to end-organ damage. These changes are mediated, at least in part, by JNK. Therefore, JNK inhibition deserves further evaluation as a potential treatment option in patients after resuscitated blood loss.

Bihippocampal damage with emotional dysfunction: impaired auditory recognition of fear.

A right-handed man developed a sudden transient, amnestic syndrome associated with bilateral hemorrhage of the hippocampi, probably due to Urbach-Wiethe disease. In the 3rd month, despite significant hippocampal structural damage on imaging, only a milder degree of retrograde and anterograde amnesia persisted on detailed neuropsychological examination. On systematic testing of recognition of facial and vocal expression of emotion, we found an impairment of the vocal perception of fear, but not that of other emotions, such as joy, sadness and anger. Such selective impairment of fear perception was not present in the recognition of facial expression of emotion. Thus emotional perception varies according to the different aspects of emotions and the different modality of presentation (faces versus voices). This is consistent with the idea that there may be multiple emotion systems. The study of emotional perception in this unique case of bilateral involvement of hippocampus suggests that this structure may play a critical role in the recognition of fear in vocal expression, possibly dissociated from that of other emotions and from that of fear in facial expression. In regard of recent data suggesting that the amygdala is playing a role in the recognition of fear in the auditory as well as in the visual modality this could suggest that the hippocampus may be part of the auditory pathway of fear recognition.

Drug refractory epilepsy in brain damage: effect of dextromethorphan on EEG in four patients.

High doses of dextromethorphan (20-42 mg/kg/day) were given to four critically ill children with seizures and frequent epileptiform abnormalities in the EEG that were refractory to antiepileptic drugs. Their acute diseases (hypoxia, head trauma and hypoxia, neurodegenerative disease, hypoglycaemia) were thought to be due in part to N-methyl-D-aspartate (NMDA) receptor mediated processes. Treatment with dextromethorphan, an NMDA receptor antagonist, was started between 48 hours and 14 days after the critical incident. In three patients the EEG improved considerably within 48 hours and seizures ceased within 72 hours. In the patient with neurodegenerative disease the effect on the EEG was impressive, but the seizures were not controlled. Despite the improvement of the EEG the clinical outcome was poor in all children: three died in the critical period or due to the progressing disease; the patient with hypoglycaemia survived with severe neurological sequelae. Plasma concentrations of dextromethorphan varied between 74-1730 ng/ml and its metabolite dextrorphan varied between 349-3790 ng/ml. In one patient corresponding concentrations in CSF were lower than those in plasma. The suppression of epileptic discharges by the doses of dextromethorphan given suggests that such doses are sufficient to block NMDA receptors.

Motion compensation strategies in magnetic resonance imaging.

Image quality in magnetic resonance imaging (MRI) is considerably affected by motion. Therefore, motion is one of the most common sources of artifacts in contemporary cardiovascular MRI. Such artifacts in turn may easily lead to misinterpretations in the images and a subsequent loss in diagnostic quality. Hence, there is considerable research interest in strategies that help to overcome these limitations at minimal cost in time, spatial resolution, temporal resolution, and signal-to-noise ratio. This review summarizes and discusses the three principal sources of motion: the beating heart, the breathing lungs, and bulk patient movement. This is followed by a comprehensive overview of commonly used compensation strategies for these different types of motion. Finally, a summary and an outlook are provided.

E2F1 mediates DNA damage and apoptosis through HCF-1 and the MLL family of histone methyltransferases.

E2F1 is a key positive regulator of human cell proliferation and its activity is altered in essentially all human cancers. Deregulation of E2F1 leads to oncogenic DNA damage and anti-oncogenic apoptosis. The molecular mechanisms by which E2F1 mediates these two processes are poorly understood but are important for understanding cancer progression. During the G1-to-S phase transition, E2F1 associates through a short DHQY sequence with the cell-cycle regulator HCF-1 together with the mixed-lineage leukaemia (MLL) family of histone H3 lysine 4 (H3K4) methyltransferases. We show here that the DHQY HCF-1-binding sequence permits E2F1 to stimulate both DNA damage and apoptosis, and that HCF-1 and the MLL family of H3K4 methyltransferases have important functions in these processes. Thus, HCF-1 has a broader role in E2F1 function than appreciated earlier. Indeed, sequence changes in the E2F1 HCF-1-binding site can modulate both up and down the ability of E2F1 to induce apoptosis indicating that HCF-1 association with E2F1 is a regulator of E2F1-induced apoptosis.
