Drosophila Food-Associated Pheromones: Effect of Experience, Genotype and Antibiotics on Larval Behavior
2016
International audience; Animals ubiquitously use chemical signals to communicate many aspects of their social life. These chemical signals often consist of environmental cues mixed with species-specific signals-pheromones-emitted by conspecifics. During their life, insects can use pheromones to aggregate, disperse, choose a mate, or find the most suitable food source on which to lay eggs. Before pupariation, larvae of several Drosophila species migrate to food sources depending on their composition and the presence of pheromones. Some pheromones derive from microbiota gut activity and these food-associated cues can enhance larval attraction or repulsion. To explore the mechanisms underlying…
Exogenous sources of regional industrial change
2017
The role of exogenous sources of new path development has been underplayed in the literature on regional industrial change so far. The aim of this article is to explore in a conceptual way under which conditions and in what ways non-local knowledge can lead to new path development in different regional innovation systems (RISs). We distinguish between organizationally thick and diversified RISs, thick and specialized RISs and thin RISs and argue that these types vary substantially in their needs for exogenous sources as well as in their capacities to attract and absorb knowledge generated elsewhere.
An attraction-based cellular automaton model for generating spatiotemporal population maps in urban areas
2015
We develop a cellular automaton (CA) model to produce spatiotemporal population maps that estimate population distributions in an urban area during a random working day. The resulting population maps are at 50 m and 5 minutes spatiotemporal resolution, showing clearly how the distribution of population varies throughout a 24-hour period. The maps indicate that some areas of the city, which are sparsely populated during the night, can be densely populated during the day. The developed CA model assumes that the population transition trends follow dynamics and propagation patterns similar to a contagious disease. Thus, our model designed to change the states of each grid cell (stable or dynami…
Totally new and pretty awesome : Amplifier–adjective bigrams in GloWbE
2017
Abstract Previous work on adjectival intensification (e.g. very good , so glad , really great ) has mostly focussed on the adverbs in question, showing that different (native) varieties of English display distinctive preferences concerning intensifier choice. However, little is known so far about the role that intensifier-adjective units (bigrams) play. The present paper offers a first contribution to fill this research gap by focussing on a data-driven approach to (mostly) high-frequency bigrams and their collocational behaviour in the Corpus of Global Web-based English (GloWbE). Asymmetric and symmetric measures are employed to establish attraction and repulsion between adverb and adjecti…
Gender differences in sexual attraction and moral judgement: research with artificial face models
2018
Sexual attraction in humans is influenced by cultural or moral factors and some gender differences can emerge in this complex interaction. A previous study (Author, 2015) found that men dissociate sexual attraction from moral judgement more than women do. Two experiments consisting of giving attractiveness ratings to photos of real opposite-sex individuals showed that men, compared to women, were significantly less influenced by the moral valence of a description about the person shown in each photo. There is evidence of some processing differences between real and artificial computer-generated faces. The present study tests the robustness of Author’s findings and extends the research to an…
Parent-child relationship trajectories during adolescence: Longitudinal associations with romantic outcomes in emerging adulthood
2010
Contains fulltext : 90774.pdf (Publisher’s version ) (Closed access) This study examined the developmental trajectories of parent-child relationships in adolescence. especially with respect to changes in support levels and negativity, and analyzed if and how these trajectories were associated with the subsequent quality of romantic relationships in young adulthood. A sample of 145 German subjects was followed across six waves (i.e. ages 14, 15. 16, 17, 21, and 23 years). Growth mixture modeling revealed three developmental trajectories of parent-child relationships across adolescence (i.e. normative, increasingly negative, and decreasingly negative/distant), which were associated with the q…
That Man Behind the Curtain: Investigating the Sexual Online Dating Behavior of Men Who Have Sex With Men but Hide Their Same-Sex Sexual Attraction i…
2016
This study investigates how men who have sex with men (MSM) use chat and dating sites based on theories of stigma-related offline behavior and online self-disclosure. We hypothesize that hidden MSM (those who self-label as heterosexual or who hide their same-sex sexual attraction from family, friends, acquaintances, or a female romantic partner) differ from open MSM in how they behave on gay chat and dating sites and in offline gay venues. Drawing on a survey of 12,002 MSM, we show that hidden MSM tend to mask their identity on gay chat and dating sites while avoiding offline gay venues. They also focus more strongly on online sexual activities (e.g., masturbating during online chats) when …
Learning at the breast: Preference formation for an artificial scent and its attraction against the odor of maternal milk
2006
International audience; Human newborns are known to display spontaneous attraction to the odor of human milk. This study aimed to assess whether the positive response to human milk odor can be explained by nursing-related learning, and whether it can be easily reassigned to a novel odor associated with nursing. Infants were exposed or not to a novel odor (camomile, Ca) during nursing, and tested on day 3–4 for their preference for camomile in comparison with either a scentless control (Exp. 1), a scented control (Exp. 2), or maternal milk (Exp. 3). Prior experience with Ca modified the newborns’ responses. While the Ca odor became more attractive than a scented control in the Ca-exposed gro…
Impact of olfactory and auditory priming on the attraction towards foods with high energy density
2015
\]\Recent research suggests that non-attentively perceived stimuli may significantly influence consumers' food choices. The main objective of the present study was to determine whether an olfactory prime (a sweet-fatty odour) and a semantic auditory prime (a nutritional prevention message), both presented incidentally, either alone or in combination can influence subsequent food choices. The experiment included 147 participants who were assigned to four different conditions: a control condition, a scented condition, an auditory condition or an auditory-scented condition. All participants remained in the waiting room during15 min while they performed a 'lure' task. For the scented condition,…
The presence of a woman increases testosterone in aggressive dominant men
2008
In line with the challenge hypothesis, this study investigated the effects of the presence of a woman on the testosterone (T) levels of young men. An informal contact with a woman of approximately 5 min resulted in an increase in salivary T among men. These effects occurred particularly in men with an aggressive dominant personality. In addition, higher salivary T levels were related to a more aggressively dominant personality, being sexual inactive for a month or more, and not being involved in a committed, romantic relationship. The most important findings of this study are that the short presence of a woman induces specific hormonal reactions in men, and that these effects are stronger f…
