Childless Aristocrats: Inheritance and the Extensive Margin of Fertility

open access: yesThe Economic Journal, 2020
Abstract Using genealogical data of British aristocrats, we show that inheritances can affect childlessness. We study settlements, a contract restricting heirs’ powers and settling bequests for yet-to-be-born generations. Settlements reduced childlessness to the ‘natural’ rate, ensuring aristocratic dynasties’ survival.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

YIPFα1A expression is regulated by multilayered molecular mechanisms

open access: yesFEBS Open Bio, EarlyView.
YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

open access: yesFEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

Volunteering at the Extensive Margin: Intrinsic or Extrinsic Motive?

open access: yesAnnals of Economics and Statistics, 2018
This paper identifies the nature of the predominant motive (consumption versus investment) moving people to offer labour for free by considering the major beneficiary sectors involved. Using basic consumption and investment models, some hy-potheses are derived and tested to identify the salient motivation for volunteering in each sector.
