Using nonequivalent dependent variables to reduce internal validity threats in quasi‐experiments: Rationale, history, and examples from practice

quasi-experiments

Hobson KA.
GSID: hMOIwNOTtkcJ
CLS Coryn, KA Hobson - New Directions for Evaluation, 2011 - Wiley Online Library

Threats to the validity of inferences and conclusions regarding the effects of applied interventions have been a major dilemma for social scientists and evaluators for several decades. One mechanism for reducing threats to internal validity and improving warrants for...

Individual differences in migratory behavior shape population genetic structure and microhabitat choice in sympatric blackcaps (Sylvia atricapilla).

Ecology and evolution

Rolshausen G, Segelbacher G, Hermes C, Hobson KA, Schaefer HM.
PMID: 24324877
Ecol Evol. 2013 Oct;3(12):4278-89. doi: 10.1002/ece3.825. Epub 2013 Oct 01.

In migratory birds, traits such as orientation and distance are known to have a strong genetic background, and they often exhibit considerable within-population variation. How this variation relates to evolutionary responses to ongoing selection is unknown because the underlying...

Discrepancies in measuring acetabular coverage: revisiting the anterior and lateral center edge angles.

Journal of hip preservation surgery

Hanson JA, Kapron AL, Swenson KM, Maak TG, Peters CL, Aoki SK.
PMID: 27011850
J Hip Preserv Surg. 2015 Jun 13;2(3):280-6. doi: 10.1093/jhps/hnv041. eCollection 2015 Oct.

The lateral center edge angle (LCEA) and the anterior center edge angle (ACEA) are commonly used to assess acetabular coverage of the femoral head. There are two distinct methods found in the literature to obtain these angles, specifically, measuring...

BEHAVIORAL DEFENSES AGAINST AVIAN BROOD PARASITISM IN SYMPATRIC AND ALLOPATRIC HOST POPULATIONS.

Evolution; international journal of organic evolution

Briskie JV, Sealy SG, Hobson KA.
PMID: 28564028
Evolution. 1992 Apr;46(2):334-340. doi: 10.1111/j.1558-5646.1992.tb02041.x.

The brown-headed cowbird (Molothrus ater) is a widespread, obligate brood parasite of North American passerine birds. In southern Manitoba, where hosts are sympatric with cowbirds, American robins (Turdus migratorius) ejected parasitic eggs from all experimentally parasitized clutches (N =...

Using stable-isotope analysis of feathers to distinguish moulting and breeding origins of seabirds.

Oecologia

Cherel Y, Hobson KA, Weimerskirch H.
PMID: 28308369
Oecologia. 2000 Feb;122(2):155-162. doi: 10.1007/PL00008843.

To determine whether stable isotope measurements of bird feathers can be used to identify moulting (interbreeding) foraging areas of adult seabirds, we examined the stable-carbon (δ

Tracing origins and migration of wildlife using stable isotopes: a review.

Oecologia

Hobson KA.
PMID: 28308009
Oecologia. 1999 Aug;120(3):314-326. doi: 10.1007/s004420050865.

To understand the ecology of migratory animals it is important to link geographic regions used by individuals including breeding, wintering, and intermediate stopover sites. Previous conventional approaches used to track animal movements have relied on extrinsic markers and typically...

The prefrontal cortex in sleep.

Trends in cognitive sciences

Muzur A, Pace-Schott EF, Hobson JA.
PMID: 12457899
Trends Cogn Sci. 2002 Nov 01;6(11):475-481. doi: 10.1016/s1364-6613(02)01992-7.

Experimental data indicate a role for the prefrontal cortex in mediating normal sleep physiology, dreaming and sleep-deprivation phenomena. During nonrandom-eye-movement (NREM) sleep, frontal cortical activity is characterized by the highest voltage and the slowest brain waves compared to other...

Age modifies the risk of atrial fibrillation among athletes: A systematic literature review and meta-analysis.

International journal of cardiology. Heart & vasculature

Ayinde H, Schweizer ML, Crabb V, Ayinde A, Abugroun A, Hopson J.
PMID: 29556526
Int J Cardiol Heart Vasc. 2018 Feb 18;18:25-29. doi: 10.1016/j.ijcha.2018.01.002. eCollection 2018 Mar.

BACKGROUND: The relationship between competitive sports and atrial fibrillation (AF) is controversial. We aimed to systematically evaluate and summarize all published observational data on the association between competitive sports and AF.METHODS AND RESULTS: We searched PubMed, EMBASE, Scopus and...

Active Inference, Curiosity and Insight.

Neural computation

Friston KJ, Lin M, Frith CD, Pezzulo G, Hobson JA, Ondobaka S.
PMID: 28777724
Neural Comput. 2017 Oct;29(10):2633-2683. doi: 10.1162/neco_a_00999. Epub 2017 Aug 04.

This article offers a formal account of curiosity and insight in terms of active (Bayesian) inference. It deals with the dual problem of inferring states of the world and learning its statistical structure. In contrast to current trends in...
