Der Gerichtshof der reinen Vernunft
2021
Die verschiedenen Urteilsstufen des Gerichtshofes der reinen Vernunft bieten einen privilegierten Zugang zur Erfassung des kantischen Begriffs menschlicher Vernunft in seiner vollen Komplexität. Wenn „menschliche Vernunft“ einerseits ein Vermögen benennt, das zur Grundausstattung unserer Erkenntnisanlagen gehört und als solches „subjektiv als ein menschliches Erkenntnisvermögen“ angesehen wird, dann ist andererseits der Mensch aufgrund eines Besitzes der Vernunft Zeuge von Entwürfen und Ansprüchen, bei deren Entsprechung er angesichts seiner Natur und seiner spezifischen Fähigkeiten nicht entscheidend ist. Die Kritik erfüllt also ihre ureigenste Aufgabe. Und das nicht nur, weil sie den Legi…
The remote and exclusive taste of border port cities
2020
Pochissime città portuali hanno un legame così esclusivo, intenso e simbiotico con il proprio porto come Hirtshals. La giovanissima città – data di nascita 1919 – è stata fondata in occasione dell’apertura di un nuovo porto artificiale sull’estremità settentrionale della Danimarca, baricentro strategico dei commerci marittimi tra i paesi scandinavi. A riflettere sulla forma e il destino del nuovo insediamento urbano si impegnarono lungamente gli architetti danesi Steen Eiler Rasmussen e Knud Christiansen, vincitori del concorso per la progettazione di Hirtshals. Eccitati dalle recenti avanguardistiche teorie della Garden City ed esaltati dall’idea di fondare una città ex-novo, il loro diseg…
Neuvostoliiton kulttuurivaihto-ohjelmat – kulttuurista kylmää sotaa vai diplomatiaa?
2011
Stalinin kuolemaa seuranneina vuosina Neuvostoliitto käynnisti mittavan kulttuurivaihto-ohjelmien sarjan. Huippuluokan neuvostoartistit vyöryivät länsimaisille areenoille. Rajoja avattiin turismille, laajennettiin ulkomaille suuntautunutta radiotoimintaa, ryhdyttiin vaihtamaan radio- ja televisio-ohjelmia myös länsimaiden kanssa, solmittiin ystävyyskaupunkisopimuksia ja osallistuttiin näyttävästi kansainvälisiin messuihin ja näyttelyihin. Simo Mikkonen käsittelee neuvostoajan kulttuurivaihto-ohjelmia ja pohtii niiden perimmäistä olemusta. peerReviewed
Immune-mediated change in the expression of a sexual trait predicts offspring survival in the wild.
2011
9 pages; International audience; BACKGROUND: The "good genes" theory of sexual selection postulates that females choose mates that will improve their offspring's fitness through the inheritance of paternal genes. In spite of the attention that this hypothesis has given rise to, the empirical evidence remains sparse, mostly because of the difficulties of controlling for the many environmental factors that may covary with both the paternal phenotype and offspring fitness. Here, we tested the hypothesis that offspring sired by males of a preferred phenotype should have better survival in an endangered bird, the houbara bustard (Chlamydotis undulata undulata). METHODOLOGY/PRINCIPAL FINDINGS: We…
State-dependent pairing behaviour in male Gammarus pulex (L.) (Crustacea, Amphipoda): effects of time left to moult and prior pairing status
2004
Because mating can be costly in terms of time and energy, an individual's propensity to engage in courtship and mating activities might be modulated by its physiological state. However, so far, state-dependent mate choice has received little attention The present study examined the effect of both prior pairing status and time left to the moult on the ability of male Gammarus pulex (Crustacea, Amphipoda) to enter in precopula with receptive females. In the lab, males that were freshly collected in precopula pairs in the field had a higher probability of re-pairing and were quicker to enter in precopula with receptive females compared to males of similar size that were freshly collected unpai…
Sexual and postmating reproductive isolation between allopatric Drosophila montana populations suggest speciation potential
2011
This work was funded by a European Commission Research Training Grant RTN2-2001-00049, the Centre of Excellence for Evolutionary Research at the University of Jyväskylä and a Marie Curie Initial Training Network, ‘Understanding the evolutionary origin of biological diversity’ (ITN-2008-213780 SPECIATION) Background: Widely distributed species with populations adapted to different environmental conditions can provide valuable opportunities for tracing the onset of reproductive incompatibilities and their role in the speciation process. Drosophila montana, a D. virilis group species found in high latitude boreal forests in Nearctic and Palearctic regions around the globe, could be an excellen…
Chemical stimuli induce courtship dominance in Drosophila
2005
Courtship dominance in male Drosophila occurs when a male directs high levels of courtship towards another male, who remains passive [1]. We investigated the cues that shape this effect and report here that it is induced by the perception of adult male cuticular hydrocarbons during a critical period.
Male relatedness and familiarity are required to modulate male-induced harm to females in
2017
Males compete over mating and fertilization, and often harm females in the process. Inclusive fitness theory predicts that increasing relatedness within groups of males may relax competition and discourage male harm of females as males gain indirect benefits. Recent studies in Drosophila melanogaster are consistent with these predictions, and have found that within-group male relatedness increases female fitness, though others have found no effects. Importantly, these studies did not fully disentangle male genetic relatedness from larval familiarity, so the extent to which modulation of harm to females is explained by male familiarity remains unclear. Here we performed a fully factorial des…
Hormonal changes of intimate partner violence perpetrators in response to brief social contact with women
2022
This study investigated whether men with a history of real-life aggressive, dominant behavior show increases in testosterone and cortisol levels after brief social contact with women. Furthermore, we tested the prediction that such changes in hormones would be larger than those observed previously in young male students. Sixty-seven male participants convicted of intimate partner violence (IPV) either had brief social contact with a female confederate (experimental condition) or a male confederate (control condition). We also performed meta-analyses to investigate whether IPV perpetrators' hormonal responses were larger than the typical responses of young male students in prior studies. All…
The Structure and Usage of Female and Male Mouse Ultrasonic Vocalizations Reveal only Minor Differences
2012
Ultrasonic vocalizations (USV) of mice are increasingly recognized as informative dependent variables in studies using mouse models of human diseases. While pup vocalizations primarily serve to re-establish contact with the mother, adult male ‘‘songs’’ were considered to be courtship signals. Alternatively, mouse USVs may generally function as territorial signals. To distinguish between these two hypotheses, we compared the structure and usage of adult male and female USVs in staged resident-intruder encounters. If calls function primarily as courtship signals, males should respond stronger than females, specifically when presented with a female intruder. Refuting this hypothesis, we found …
