Are Men Less Generous to a Smarter Woman? Evidence from a Dictator Game Experiment [PDF]

open access: yesarXiv, 2020
Although evidence suggests men are more generous to women than to men, it may stem from paternalism and could reverse when women excel in important skills for one's career success, such as cognitive skills. Using a dictator game, this paper studies whether male dictators allocate less to female receivers than to male receivers when these receivers have

Dermatophyte infection of the male genitalia

open access: yesIndian Journal of Dermatology, 2009
Dermatophyte infection is a very common disease, but that of the male genitalia is said to be rare. Here we report four cases of dermatophyte infection of the male genitalia, of which one had lesion on the penis alone, one had lesions on the penis and the groins, one had lesions on penis and scrotum, and the other had involvement of scrotum, penis and ...

Interaction Mechanisms Quantified from Dynamical Features of Frog Choruses [PDF]

open access: yesarXiv, 2019
Interaction mechanism in the acoustic communication of actual animals is investigated by combining mathematical modeling and empirical data. Here we use a deterministic mathematical model (a phase oscillator model) to describe the interaction mechanism underlying the choruses of male Japanese tree frogs (Hyla japonica) in which the male frogs attempt ...

Male Genitalia of Apis Species [PDF]

open access: yesNature, 1960
THE external parts of the male genitalia of Apis species are poorly developed, and an elaborate structural modification of the internal walls of the aedeagus is everted during copulation. Hitherto undescribed except for A. mellifera, this apparatus has now been examined in specimens of the other three species from Ceylon kindly obtained by Dr. B.

BOTH MALE AND FEMALE NOVEL TRAITS PROMOTE THE CORRELATED EVOLUTION OF GENITALIA BETWEEN THE SEXES IN AN ARTHROPOD

open access: yesEvolution; international journal of organic evolution, 2014
The correlated evolution of genitalia between sexes has been demonstrated in many taxa. However, it remains unclear whether female rather than male genitalia can play a key role in the correlated evolution of male and female genitalia.

Frequency and Viability of Diploid and Haploid Males Offsprings of Mated Females of Solitary Endoparasitoid (DIADROMUS Pulchellus) (Ichneumonidae) [PDF]

open access: yesComptes Rendus de l'Academie des Sciences. Serie 3, Sciences de la Vie 324 (2001) 149-158, 2006
Sex determination in the order Hymenoptera is based on arrhenotoky, hymenopteran males are usually haploid and females diploid. Males of the Ichneumonidae Diadromus pulchellus, solitary endoparasitoid of A. assectella pupae are normally haploid, but diploid males are present in a natural population and can be obtained in a experimental population.
