Propensity Score Augmentation in Matching-based Estimation of Causal Effects [PDF]

open access: yesarXiv
When assessing the causal effect of a binary exposure using observational data, confounder imbalance across exposure arms must be addressed. Matching methods, including propensity score-based matching, can be used to deconfound the causal relationship of interest. They have been particularly popular in practice, at least in part due to their simplicity

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.

Modeling sexual selection in Túngara frog and rationality of mate choice [PDF]

open access: yesarXiv, 2016
The males of the specie of frogs Engystomops pustulosus produce simple and com- plex calls to lure females, as a way of Intersexual selection. Complex calls lead males to a greater reproductive success than simple calls do. However, the complex calls are also more attractive to the main predator of these amphibians, the bat Trachops cirrhosus ...

Expressions of Sentiments During Code Reviews: Male vs. Female [PDF]

open access: yesProceedings of the 26th IEEE International Conference on Software Analysis, Evolution and Reengineering, 2018, 2018
Background: As most of the software development organizations are male-dominated, female developers encountering various negative workplace experiences reported feeling like they "do not belong". Exposures to discriminatory expletives or negative critiques from their male colleagues may further exacerbate those feelings.

Mating Instabilities Lead to Sympatric Speciation [PDF]

open access: yesarXiv, 2002
One of the most challenging issues of evolutionary biology concerns speciation, the emergence of new species from an initial one. The huge amount of species found in nature demands a simple and robust mechanism. Yet, no consensus has been reached concerning a reasonable disruptive selection mechanism that prevents mixing genes among the emerging ...
