Als Marie Bonaparte sich taub stellte ...

Between 1927 and 1931 Marie Bonaparte had herself operated upon her clitoris three times. She did so against Freud's advice with whom she was in analysis. Among psychoanalysts these operations are still often regarded as "errors" or aberrations. But for Marie Bonaparte, who was in various ways familiar with physics and a somatic approach, surgery was the first choice, psychoanalysis only a possible alternative. She was not impressed by the skepticism of her colleagues, and adhered even more emphatically to her own strategy

The importance of root-produced volatiles as foraging cues for entomopathogenic nematodes

Background Entomopathogenic nematodes (EPNs) are tiny parasitic worms that parasitize insects, in which they reproduce. Their foraging behavior has been subject to numerous studies, most of which have proposed that, at short distances, EPNs use chemicals that are emitted directly from the host as host location cues. Carbon dioxide (CO2) in particular has been implicated as an important cue. Recent evidence shows that at longer distances several EPNs take advantage of volatiles that are specifically emitted by roots in response to insect attack. Studies that have revealed these plant-mediated interactions among three trophic levels have been met with some disbelief. Scope This review aims to take away this skepticism by summarizing the evidence for a role of root volatiles as foraging cues for EPNs. To reinforce our argument, we conducted olfactometer assays in which we directly compared the attraction of an EPN species to CO2 and two typical inducible root volatiles. Conclusions The combination of the ubiquitous gas and a more specific root volatile was found to be considerably more attractive than one of the two alone. Hence, future studies on EPN foraging behavior should take into account that CO2 and plant volatiles may work in synergy as attractants for EPNs. Recent research efforts also reveal prospects of exploiting plant-produced signals to improve the biological control of insect pests in the rhizosphere.

Une première réflexion de Nicolas Jacquier concernant les démons : le De calcatione demonum seu malignorum spirituum (1457)

The De calcatione demonum seu malignorum spirituum was written in 1457 by Nicolas Jacquier, one year before his most famous work, the Flagellum hereticorum fascinariorum. The De calcatione offers initial reflections by the Burgundian dominican inquisitor on diabolical modes of actions directed at human beings and on the means at the disposal of priests and their faithful to control, expel, and trample (calcare) them. This relatively unknown text is produced at a time when purely demonological issues are linked to those on diabolical witchcraft and the sabbath. The author tries in particular to promote the idea of trampling demons, which is understood as their punishment. Now vanquished, demons are compelled to serve divine truth. In a climate of skepticism about the need to fight withcraft, the De calcatione offers an interesting reflexion about the truth status of diabolical and heretical discourses when submitted to divine power. This reflexion is based on the model of the positive figure of the possessed from exampla and from dominican hagiography. The treatise therefore aims to counter the tradition of the Episcopi canon which argues for the illusory nature of demons. Instead, it offers an argument about the reality of their actions on the occasion of the sabbat

Brand Authenticity: An Integrative Framework and Measurement Scale

Although brand authenticity is gaining increasing interest in consumer behavior research and managerial practice, literature on its measurement and contribution to branding theory is still limited. This article develops an integrative framework of the concept of brand authenticity and reports the development and validation of a scale measuring consumers' perceived brand authenticity (PBA). A multi-phase scale development process resulted in a 15-item PBA scale measuring four dimensions: credibility, integrity, symbolism, and continuity. This scale is reliable across different brands and cultural contexts. We find that brand authenticity perceptions are influenced by indexical, existential, and iconic cues, whereby some of the latters' influence is moderated by consumers' level of marketing skepticism. Results also suggest that PBA increases emotional brand attachment and word-of-mouth, and that it drives brand choice likelihood through self-congruence for consumers high in self-authenticity.
