The C. elegans LIM homeobox gene lin-11 specifies multiple cell fates during vulval development [PDF]

, 2003
LIM homeobox family members regulate a variety of cell fate choices during animal development. In C. elegans, mutations in the LIM homeobox gene lin-11 have previously been shown to alter the cell division pattern of a subset of the 2° lineage vulval ...

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

Animal Conservation, EarlyView.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Autism, the Integrations of 'Difference' and the Origins of Modern Human Behaviour [PDF]

, 2009
It is proposed here that the archaeological evidence for the emergence of 'modern behaviour' (160,000-40,000 bp) can best be explained as the rise of cognitive variation within populations through social mechanisms for integrating 'different minds ...

Parents' experiences in accessing services for their autistic children in the United Kingdom: A meta‐synthesis

British Journal of Clinical Psychology, EarlyView.
Abstract Background Parents of autistic children support their children through additional challenges, often experiencing adversity as a result. Such parents report high support needs, yet service provision is often limited. Services often support children through providing various psychological interventions to parents.

Frequency estimation of disease-causing mutations in the Belgian population of some dog breeds, part 1 : shepherds [PDF]

, 2016
In light of improving breeding advice, the frequency was estimated for all the disease-causing mutations that were known at the start of the study and that are potentially relevant for a group of dog breeds, which are relatively popular or in which the ...

Clues to the formation of spiral structure in M51 from the ages and locations of star clusters [PDF]

, 2017
We determine the spatial distributions of star clusters at different ages in the grand-design spiral galaxy M51 using a new catalog based on multi-band images taken with the Hubble Space Telescope (HST). These distributions, when compared with the spiral

A tutorial on Bayesian model averaging for exponential random graph models

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The use of exponential random graph models (ERGMs) is becoming prevalent in psychology due to their ability to explain and predict the formation of edges between vertices in a network. Valid inference with ERGMs requires correctly specifying endogenous and exogenous effects as network statistics, guided by theory, to represent the network ...

To vary or not to vary: A flexible empirical Bayes factor for testing variance components

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Random effects are the gold standard for capturing structural heterogeneity, such as individual differences or temporal dependence. Yet testing their presence is difficult because variance components are constrained to be non‐negative, creating a boundary problem. This paper introduces a flexible empirical Bayes factor (EBF) for testing random

Global value chain participation and optimal monetary policy in a small open economy

Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.
Abstract This paper examines the effects of monetary policy in a small open economy participating in the global value chains by constructing a model with firm heterogeneity and production fragmentation. Liquidity constraints and terms‐of‐trade externality distort the sorting of firms into different operations.
