Adaptive Experimental Design Using the Propensity Score [PDF]

open access: yes
Many social experiments are run in multiple waves, or are replications of earlier social experiments. In principle, the sampling design can be modified in later stages or replications to allow for more efficient estimation of causal effects.

Threshold Crossing Models and Bounds on Treatment Effects: A Nonparametric Analysis [PDF]

open access: yes
This paper considers the evaluation of the average treatment effect of a binary endogenous regressor on a binary outcome when one imposes a threshold crossing model on both the endogenous regressor and the outcome variable but without imposing parametric

The pyruvate generator is a common phenomenon in mitochondria from different rat and mouse brain regions

open access: yesFEBS Letters, EarlyView.
The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

Forced to Be Rich? Returns to Compulsory Schooling in Britain [PDF]

open access: yes
Do students benefit from compulsory schooling? Researchers using changes in compulsory schooling laws as instruments have typically estimated very high returns to additional schooling that are greater than the corresponding OLS estimates and concluded ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Modelling Contract Farming Impact on Poultry Farm Income: Lessons from the Nigerian Anchor-Borrower Outgrowers’ Programme

open access: yesJournal of Agriculture and Environment for International Development
Contract farming was introduced in Nigeria to address the challenges faced by smallholder farming households in realising farming objectives. Therefore, this study examined the effectiveness of the Anchor-borrower Outgrowers’ Programme in fulfilling one

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

open access: yesFEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.
