We explore how honesty-humility and the other HEXACO personality traits relate to citizens’ nascent ambition and their recruitment to run for office. We extend previous work on virtue-related personality traits and political recruitment in two important ways: we go beyond North America and conduct a five-country cross-national study with nationally representative samples. More importantly, going beyond individual-level differences in nascent ambition, we also address how honesty-humility predicts the likelihood of being asked to and actually running for office. Based on data from Canada, Denmark, Israel, the Netherlands, and Switzerland, we demonstrate that citizens with lower levels of honesty-humility are more likely to have considered running, to deem themselves qualified to run, to have been asked to run, and to actually have run for a political office. From a ‘virtue ethics’ perspective, this is highly concerning: low honesty-humility predisposes individuals to engage in unethical behavior and decision-making. We discuss implications for the quality of political representation.

As a version of the secretary problem, Ferguson, Hardwick and Tamaki (1992) considered an optimal stopping problem called the duration problem. The basic duration problem is the classical duration problem, in which the objective is to maximize the time of possession of a relatively best object when a known number of rankable objects appear in random order. In this paper we generalize this classical problem in two directions by allowing the number N (of available objects) to be a random variable with a known upper bound n and also allowing the objects to appear in accordance with Bernoulli trials. Two models can be considered for our random horizon duration problem according to whether the planning horizon is N or n. Since the form of the optimal rule is in general complicated, our main concern is to give to each model a sufficient condition for the optimal rule to be simple. For N having a uniform, generalized uniform, or curtailed geometric distribution, the optimal rule is shown to be simple in the so-called secretary case. The asymptotic results, as n → ∞, will also be given for these priors.

It was suggested by Ronald Fisher in 1931 that genes that benefit the male (including those required for spermatogenesis) would accumulate on the Y chromosome. Following the discovery that microdeletions of the Y chromosome were associated with diverse spermatogenic phenotypes, at least three intervals that contain one or more genes controlling male germ-cell differentiation have been identified in humans. These intervals, named AZFa, AZFb and AZFc, have been mapped, cloned and examined in detail for the presence of functional genes. In this review, I have discussed the genes that map to the AZF intervals and the evidence indicating which ones are the most likely candidates underlying Y-linked male infertility. In addition, I have considered the analysis of key intervals on the mouse Y chromosome, where it provides comparative data supporting the role of a candidate gene in an infertility phenotype.
