La demande d’effacement de cicatrices cutanées

International audienceEn dermatologie, les progrès technologiques et leur médiatisation suscitent des demandes de plus en plus fréquentes d’effacement des cicatrices (cicatrices post–chirurgicales, cicatrices post-traumatiques, cicatrices d’acné, cicatrices auto-provoquées (excoriations, scarifications, automutilations) … Les attentes sont fortes et les demandes souvent pressantes chez ces patients qui ont une véritable souffrance avec sentiments de honte et culpabilité. Une réponse opératoire immédiate, sans entendre la demande latente derrière la demande d’effacement des cicatrices, risque d’aggraver la souffrance

Echoes of romanticism and fantastic literature in psychoanalysis

This paper maps the historical, aesthetic, and epistemic processes of the 18th and 19th centuries that associate romanticism, fantastic literature and psychoanalysis. We argue that fantastic is an important vector through which elements of Romanticism were incorporated into the psychoanalytic model of the psyche. Assuming that such Romantic influences were assimilated selectively and creatively, we highlight some points of contention and compromise between romanticism and the Enlightenment that were later resumed and transformed by fantastic literature and psychoanalysis: the themes of love, madness, sexuality, superstitions and myths; the relationship between reality and its representations and between thought and consciousness; and the rhetorical use of irony. Finally, the text points to the psychoanalytic approach of the uncanny (Unheimliche) as the most sensitive moment of such exchange.Mapeiam-se os processos históricos, estéticos e epistêmicos dos séculos XVIII e XIX que associam romantismo, literatura fantástica e psicanálise. Defende-se que o fantástico constitui um importante vetor por meio do qual elementos do romantismo foram incorporados ao modelo psicanalítico de aparelho psíquico. Parte-se da perspectiva de que a assimilação da influência romântica realizou-se de forma seletiva e criativa. Destacam-se alguns pontos de tensões e compromissos entre romantismo e o iluminismo, que foram retomados e transformados pelo fantástico e a psicanálise: as temáticas do amor, da loucura, da sexualidade, das superstições e dos mitos; o questionamento da relação entre o real e suas representações e entre pensamento e consciência; e a valorização do uso retórico da ironia. Aponta-se a abordagem psicanalítica do infamiliar (Unheimliche) como o momento mais sensível dessa interlocução

Bouncing back from failure: Entrepreneurial resilience and the internationalization of subsequent ventures created by serial entrepreneurs

This paper examines the impact over international propensity of past negative entrepreneurial experience for those who re-enter into entrepreneurial activity; referred to as resilient serial entrepreneurs. We first hypothesize on the effects over entrepreneurial re-entry that such negative past experience may have and highlight the link between the past entrepreneurial experience of resilient entrepreneurs and their subsequent propensity towards international markets. Building on insights from the generative experiential learning process of entrepreneurial activity and from cognition theories, we propose that resilient entrepreneurs who re-enter business despite having faced negative entrepreneurial experiences in the past benefit from enriched cognitive schemas leading them to greater export propensity. The proposed hypotheses are tested on a unique sample drawn from a Spanish adult population survey. Results from the sequential deductive triangulation analysis (QUAN -> qual) reveal that practical experience is an essential prerequisite for entrepreneurial learning, and that the resilience of those with negative entrepreneurial experience induces the generative entrepreneurial learning especially suitable for subsequent internationally oriented ventures.Peer ReviewedPreprin

Coordination and Output Attainment in Work Units Performing Non-routine Tasks: A Cross- National Study

Based on an information-processing perspective (Galbraith 1972), a theoretical pro position is advanced which predicts that for work units performing non-routine tasks, the effect of unit coordination on output attainment is contingent on the sources from which the unit acquires information for task performance. This proposition is tested using a cross-national research design. Data from four national samples — Austria, Belgium, Hungary, and Poland — of academic research units support the proposition. The results reinforce the need for a contingency approach to the study of coordination and performance in organizations. They also provide some insight into the interplay between society and organization.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68600/2/10.1177_017084068500600102.pd

EJNMMI Res

Inflammatory vascular disease of the arteries, such as inflamed atheromatous plaques or arteritis, may cause aneurysms or ischemic strokes. In this context, using positron emission tomography (PET) to image inflammation may help select patients who would benefit from appropriate therapeutic interventions. This study sought to assess the usefulness of the 18 kDa translocator protein (TSPO) tracers [C]-PBR28 and [F]-PBR06 for imaging inflammatory vascular disease in vitro and in vivo. Immunohistochemistry for macrophage infiltration as well as autoradiography with [F]-PBR06 were performed on eight paraffin-embedded, formalin-fixed atherosclerosis plaques prospectively collected after carotid endarterectomy of eight patients affected by ischemic stroke. Six different patients, one of whom was also included in the in vitro study, underwent PET imaging. Two patients with carotid stenosis associated with ischemic stroke were imaged with [F]-PBR06 PET/CT, and four other patients (three with large vessel vasculitis and one with bilateral carotid stenosis but without stroke) were imaged with [C]-PBR28. All in vitro sections showed specific binding of [F]-PBR06, which co-localized with immunohistochemistry markers for inflammation. However, in vivo TSPO imaging with either [C]-PBR28 or [F]-PBR06 was negative in all participants. Despite good uptake on surgical samples in vitro, [C]-PBR28 and [F]-PBR06 are not viable clinical tools for imaging inflammatory vascular disease.
