The symptom remains a kind of "royal road" into get to the day hospital. But what does it convey ? What innovative therapeutic responses can the day hospital provide ? After a brief reflexion on the symptom, from a semiologic and diagnostic point of view, and an overview of the psychodynamic, systemic and cognitive-behavioral models, we will examine the ingredients that nourish the integrative therapeutic work at the day hospital. Through clinical vignettes, we will describe the work of our institution by highlighting elements related to the concepts of institutional psychotherapy, setting, individual and group transferences and counter-transferences, holding, maternal and paternal functions, intrasubjective and intersubjective reality, object-shoring, and psychological envelope. We will present a particular therapeutic activity called "My Key" by looking at the work of symbolization carried out at the hospital, as well as the notions of the malleable medium and the transitional object. We will see how the day hospital, as an area of care within the scope of a temporal discontinuity, enables psychic continuity and opens the road to the subject’s recovery. [less ▲]

Representations of childbirth in fifteenth-century devotional and historical manuscripts are invariably depicted as post-partum confinement scenes in a domestic interior. These images appear to show a ‘gendered space’ in which women care for each other and men are marginalized. Neglected by medieval art historians, such pictures have been uncritically used by historians of obstetric and social history to prove that childbirth was the one time when medieval women exercised power and control in an otherwise patriarchal society. However, as with all historical evidence, these images do not offer us unmediated access to the past. This thesis brings these domestic, post-partum pictures of childbirth to the centre of an art historical enquiry by undertaking a survey of this iconography in some fifty fifteenth-century manuscripts and incunables. Since the occurrence of this generic iconography cannot be consistently associated with female spectators, it has been necessary to reassess in what way they might be en/gendered: how they were received by their original viewers (male and female) and how we can bring them into meaning as sources for reconstructing the lives of medieval women. To avoid equating these images with reality and reducing the female sex at large to the maternal function, I develop a methodology to show how the social viewing positions occupied by certain spectators would have rendered them sensitive to images of maternity and childbirth. Specifically, I argue that the images of childbirth in a group of fifteenth-century Books of Hours made for male and female members of the houses of Anjou and Brittany would have been seen with a ‘situational eye’ that was informed by the requirements of patriarchal, aristocratic families, and by the dangers surrounding childbirth. My thesis demonstrates that this situational eye can be extended beyond the field of art history to show how other sources from fifteenth-century childbearing such as charms, lying-in, and churching, can be brought into meaning for the women whose social position required them to conceive and give birth to male heirs.

This paper surveys recent advances in valorization of transition-metal-catalyzed enyne metathesis as key events in the total synthesis of naturally occurring compounds of biological and medicinal importance. Special attention is devoted to methodologies based on dienyne ring-closing metathesis (RCM) applied in tandem and sequential processes, on relay ring-closing metathesis (RRCM), ring-rearrangement metathesis (RRM), enyne cross-metathesis (CM) and enyne skeletal bond reorganization, all proceeding under metalcarbenes (Ru or Mo alkylidenes) or metal-salts (Pd or Pt) catalysis. The high potential of these procedures in constructing versatile scaffolds as essential structural cores of a diversity of bioactive natural products is highlighted. Inventive functionalizations by non-metathesis transformations intervening in the total synthesis of the targeted natural compounds, prior to (Michael addition, Wittig olefination, allylation etc.) or after (Diels-Alder cycloaddion, Heck and Suzuki-Miyaura reactions, Dess-Martin oxidation, dihydroxylation, epoxidation etc.) the pivotal metathesis step have also been included.

We herein describe the straightforward synthesis of a stable pyridyl(4- methoxyphenyl)iodonium salt and its [18F]radiolabelling within a one-step, fully automated and cGMP compliant radiosynthesis of [18F]UCB-H ([18F]7), a PET tracer for the imaging of Synaptic Vesicle glycoprotein 2A (SV2A). Over the course of one year, 50 automated productions provided 34±2% of injectable [18F]7 from up to 285 GBq (7.7 Ci) of [18F]fluoride in 50 minutes (uncorrected radiochemical yield. Specific Activity = 815±185 GBq/μmol). The successful implementation of our synthetic strategy within routine, high-activity and cGMP productions attests to its practicality and reliability for the production of large doses of [18F]7. In addition to enabling efficient and cost-effective clinical research on a range of neurological pathologies through the imaging of SV2A, this work further demonstrates the real value of iodonium salts for the cGMP 18F-PET tracer manufacturing industry, and their ability to fulfill practical and regulatory requirements in that field.

NASA has funded a project called the Hunt for Observable Signatures of Terrestrial Systems (HOSTS) to survey nearby solar type stars to determine the amount of warm zodiacal dust in their habitable zones. The goal is not only to determine the luminosity distribution function but also to know which individual stars have the least amount of zodiacal dust. It is important to have this information for future missions that directly image exoplanets as this dust is the main source of astrophysical noise for them. The HOSTS project utilizes the Large Binocular Telescope Interferometer (LBTI), which consists of two 8.4-m apertures separated by a 14.4-m baseline on Mt. Graham, Arizona. The LBTI operates in a nulling mode in the mid-infrared spectral window (8-13 μm), in which light from the two telescopes is coherently combined with a 180 degree phase shift between them, producing a dark fringe at the location of the target star. In doing so the starlight is greatly reduced, increasing the contrast, analogous to a coronagraph operating at shorter wavelengths. The LBTI is a unique instrument, having only three warm reflections before the starlight reaches cold mirrors, giving it the best photometric sensitivity of any interferometer operating in the mid-infrared. It also has a superb Adaptive Optics (AO) system giving it Strehl ratios greater than 98% at 10 μm. In 2014 into early 2015 LBTI was undergoing commissioning. The HOSTS project team passed its Operational Readiness Review (ORR) in April 2015. The team recently published papers on the target sample, modeling of the nulled disk images, and initial results such as the detection of warm dust around η Corvi. Recently a paper was published on the data pipeline and on-sky performance. An additional paper is in preparation on β Leo. We will discuss the scientific and programmatic context for the LBTI project, and we will report recent progress, new results, and plans for the science verification phase that started in February 2016, and for the survey.

Resistance to change and micro-politics around change processes have been studied by many social scientists. In the managerial field, numerous authors plead for the adoption of participative methods in order to overcome such phenomena but few of them seriously document the way in which the so-called “human factor” may be really taken into consideration in the management of change projects. Is there a direct relation between the managerial ability to cope with power games and the final results of a change project? Does a participatory strategy necessarily lead to a successful change? What are the conditions under which the enactment of micropolitics may contribute to an effective organizational transformation? We will here focus on change processes occurring in the public sphere: the NPM school of thought led to a large range of organizational reforms in which the civil servants’ engagement and motivation appear to play a crucial role. Our research questions will be discussed through the presentation of two cases studies of Belgian public organizations concerned with the implementation of an electronic document management system (DMS). The first case is located in the Federal Police department while the second occurs in a regional administration. Both are issued from action-researches undertaken with my research team during the last decade. They have been selected in order to contrast the different ways in which power games and end-users resistances may be enacted by senior management. They will help us to distinguish two management styles and to explore their respective impact on the change process itself. [less ▲]

A non-aqueous CE method was developed for evaluating the chiral discrimination potential of cinchona alkaloids and different kinds of carbamoylated derivatives of quinine and quinidine type chiral selectors towards acidic analytes, in particular a series of various Bz (benzoyl), DNB (3,5-dinitrobenzoyl) and DNZ (3,5-dinitrobenzyloxycarbonyl) amino acid derivatives. In this study, the enantioselectivity values obtained in non-aqueous CE with tert-butyl carbamoylated quinine as chiral additive have been compared with the values found for the same series of selectands in HPLC using the same selector immobilized onto silica as chiral stationary phase. Similarly to the background electrolyte used in CE an ethanol-methanol mixture (60:40, v/v) containing 100 mM octanoic acid and 12.5 mM ammonia has been selected as HPLC mobile phase. Under these conditions, a good correlation (r=0.954) between the enantioselectivities observed with the two techniques has been obtained. Thus the non-aqueous CE method can be applied as a screening tool for the rapid evaluation of the chiral discrimination potential of a large set of newly developed chiral selectors derived from quinine and related alkaloids.
