Family Matters: Exploring the Link Between Parental and Executive Financial Misconduct

open access: yesJournal of Accounting Research, EarlyView.
ABSTRACT Using a novel data set of misconduct records for Finnish CEOs and directors and their parents, we explore whether corporate executives’ financial misconduct is associated with similar behavior by their parents. Controlling for various other factors of executive financial misconduct, we find that executives are significantly more likely to ...

Neoclassical development of genetic sexing strains for insect pest and disease vector control

open access: yesInsect Science, EarlyView.
The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

The Effects of Assortative Mating on Income Inequality: A Decompositional Analysis

open access: yes, 2006
Using the Australian Bureau of Statistics’ Survey of Income and Household Costs, this paper explores the effect of changing assortative mating patterns on income inequality.

Colour Morphs as Alternative Solutions to the Trade‐Off Predicted by the Immuno‐Competence Handicap Hypothesis

open access: yesIntegrative Zoology, EarlyView.
In this study, we tested whether white and yellow morphs of the common wall lizard (Podarcis muralis) adopt alternative strategies shaped by the immuno‐competence handicap hypotheses (ICHH). We found that testosterone‐induced immune suppression was stronger in white males, while aggression decreased in both morphs.

Variation in sexual dimorphism and assortative mating do not predict genetic divergence in the sexually dimorphic Goodeid fish Girardinichthys multiradiatus

open access: yesCurrent Zoology, 2012
Sexual dimorphism is often used as a proxy for the intensity of sexual selection in comparative studies of sexual selection and diversification. The Mexican Goodeinae are a group of livebearing freshwater fishes with large variation between species in ...

Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

open access: yesIntegrative Zoology, EarlyView.
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.

Asymmetric Platform Oligopoly

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT We propose a tractable model of asymmetric platform oligopoly with logit demand in which users from two distinct groups are subject to within‐group and cross‐group network effects and decide which platform to join. We characterize the equilibrium when platforms manage user access by setting participation fees for each user group.

Do olive ridley turtles select mates based on size? An investigation of mate size preference at a major arribada rookery

open access: yesEcosphere
We investigated mate size preferences in olive ridley sea turtles (Lepidochelys olivacea), one of the world's smallest and most abundant sea turtle species, using data from two years near a single mass nesting site.
