Alcohol boosts pheromone production in male flies and makes them sexier
2020
The attraction of Drosophila melanogaster towards byproducts of alcoholic fermentation, especially ethanol, has been extensively studied 1–4. However, the adaptive value of this behavior has not been elucidated. Previous studies have suggested anthropomorphic interpretations of D. melanogaster behavior towards alcohols 5,6. Here, we instead assert that there exists a simple yet vital biological rationale for alcohol contact and consumption by these insects. We show that exposure to alcohols, especially methanol, results in an immediate amplification of fatty acid ester pheromone levels, which in turn elevates the probability that a male will successfully compete for a female during courtshi…

Persepsi Masyarakat Lokal Terhadap Pengembangan Hutan Mangrove Sebagai Kawasan Ekowisata Di Kampung Ruar Distrik Biak Timur Kabupaten Biak Numfor
2021
The mangrove forest area of Kampung Ruar, East Biak District, is an area that has traditionally been a place for fishing and lime-making efforts by the community who have been hereditary. This condition raises questions from various parties whether this location is suitable to be developed as a mangrove ecotourism destination. Development of Mangrove Ecotourism by the Papua Provincial Forestry Service as a tourist attraction by utilizing local natural potential and supporting tourism policies in Biak Numfor Regency. This study aims to see the socio-cultural conditions of local communities in the Mangrove Forest Area of Kampung Ruar, Biak Timur District, Biak Numfor Regency as an ecotour…
Film Tourism – Locations Are the New Stars
2009
There once was a time when the actual attraction of a movie lied in the capability of the celluloid to let the spectators escape from the everyday, a spare time to leave the life-world environment behind and live the life of a thrilling armchair traveller. Foreign countries and remote regions could easily be mapped and visited without travelling to the actual location. Considering that “the modern world is very much a ‘seen’ phenomenon“ (Jenks 1995:2), one has to come to the assumption that present day travelling and watching movies are somehow connected. Tourism originally was perceived as visitors travelling, whether within their own country or internationally, for pleasure and relaxation…
Data from: Phylogenomics of Lophotrochozoa with consideration of systematic error
2021
Phylogenomic studies have improved understanding of deep metazoan phylogeny and show promise for resolving incongruences among analyses based on limited numbers of loci. One region of the animal tree that has been especially difficult to resolve, even with phylogenomic approaches, is relationships within Lophotrochozoa (the animal clade that includes molluscs, annelids, and flatworms among others). Lack of resolution in phylogenomic analyses could be due to insufficient phylogenetic signal, limitations in taxon and/or gene sampling, or systematic error. Here, we investigated why lophotrochozoan phylogeny has been such a difficult question to answer by identifying and reducing sources of sys…

Intelligence can be detected but is not found attractive in videos and live interactions
2021
Humans’ extraordinary intelligence seems to extend beyond the needs for survival. One theory to explain this surplus intelligence is that it evolved via sexual selection as a fitness indicator to advertise genetic quality to prospective mates. Consistent with this idea, self-reported mate preferences suggest intelligence is valued across cultures. Yet, as the validity of these self-reports has been questioned, it remains unclear whether objectively assessed intelligence is indeed attractive. We analysed data from two studies to test this key premise of the sexual selection theory of intelligence. In Study 1, 88 target men had their intelligence measured and based on short video clips were r…
Interaction Theory and the Social Network
1967
Interaction theorists have delineated the close association in friendship relations between value consensus, affectional closeness, and interaction. Categorical investigations of the social network have focused upon frequency of interaction with friends and kin. In the present paper a componential theory of attraction in the social network is developed in order to link previous theoretical discussions with the empirical social network categories. Two attractional variables, one based upon consensus and the other upon positive concern, are perceived as interpreting friendship and kinship involvements. Consensus tends to be modal in friendship and positive concern in kinship, though there are…
Reggae Outernational: Borders and Trans/National Identity in Jamaican Popular Music
2020
International audience; The history of post-1945 Jamaican popular music is one of constantly changing borders. Despite efforts on the part of the Jamaican state to turn reggae into Jamaica’s exclusively national music and a tourist attraction, reggae and its related subgenres remain to this day a minority culture of the underground, in Jamaica itself and in the many places around the world where it is produced and performed. Recent research on the history of Jamaican popular music suggests that it cannot easily be contained within strictly national borders. Reggae can rather be seen as a focal point around which an incipient alter/native, working-class Jamaican identity is built, both insid…
Infants' hedonic responsiveness to food odours: a longitudinal study during and after weaning (8, 12 and 22 months)
2013
Abstract Background Olfaction is a highly salient sensory modality in early human life. Neonates show keen olfactory sensitivity and hedonic responsiveness. However, little is known about hedonic olfactory responsiveness between the neonatal period and 2 years of age. In an attempt to fill this gap, this longitudinal follow-up study aimed at investigating hedonic responses to food odours in infants during the first 2 years of life. The second objective was to evaluate whether gender has an influence on hedonic responses during this early period. Four control stimuli and eight odours (four rated by adults as a priori pleasant and four a priori unpleasant) were presented in bottles to 235 inf…
