An Enhancement to the Theory and Measurement of Purpose

Larry H. Ludlow, Theresa O'Keefe, Henry Braun, Ella Anghel, Olivia Szendey, Christina Matz & Burton Howell
Development of purpose is an important goal of post-secondary education. This study advances the measurement of purpose by (a) enriching the construct through incorporating the facet of horizon; (b) providing a framework for Rasch/Guttman Scenario score interpretation; and (c) providing evidence of convergent, divergent, and known groups validity.

Examining the Impact of a Consensus Approach to Content Alignment Studies

An Intersectional Approach to Differential Item Functioning: Reflecting Configurations of Inequality

Michael Russell & Larry Kaplan
Differential Item Functioning (DIF) is commonly employed to examine measurement bias of test scores. Current approaches to DIF compare item functioning separately for select demographic identities such as gender, racial stratification, and economic status. Examining potential item bias fails to recognize and capture the intersecting configurations of inequality (McCall, 2001) specific to a person's identify which impact item bias. The study presented here explores an intersectional approach to the flagging of items for content review...

Data from: Aversion to playing God predicts negative moral judgments of technology and science

Adam Waytz & Liane Young
This research provides, to our knowledge, the first systematic empirical investigation of people's aversion to playing God. Seven studies validate this construct and show its association with negative moral judgements of science and technology. Motivated by three nationally representative archival datasets that demonstrate this relationship, studies 1 and 2 demonstrate that people condemn scientific procedures they perceive to involve playing God. Studies 3–5 demonstrate that dispositional aversion to playing God corresponds to decreased willingness to...

Causes of oceanic crustal thickness oscillations along a 74-Myr Mid-Atlantic Ridge flow line

William Shinevar, Hannah Mark, Fiona Clerc, Emmanuel A. Codillo, Jianhua Gong, Jean-Arthur Olive, Stephanie Brown, Paris T. Smalls, Yang Liao, Véronique Le Roux & Mark Behn
Gravity, magnetic, and bathymetry data collected along a continuous 1400-km-long spreading-parallel flow line across the Mid-Atlantic Ridge indicate significant tectonic and magmatic fluctuations in the formation of oceanic crust over a range of timescales. The transect spans from 28 Ma on the African Plate to 74 Ma on the North American plate, crossing the Mid-Atlantic Ridge at 35.8 ºN. Gravity-derived crustal thicknesses vary from 3–9 km with a standard deviation of 1 km. Spectral analysis...

Data from: Children reject inequity out of spite

Katherine McAuliffe, Peter R. Blake & Felix Warneken
When confronted with inequality, human children and adults sacrifice personal gain to reduce the pay-offs of other individuals, exhibiting apparently spiteful motivations. By contrast, sacrifice of personal gain by non-human animals is often interpreted as frustration. Spite may thus be a uniquely human motivator. However, to date, no empirical study has demonstrated that psychological spite actually drives human behaviour, leaving the motivation for inequity aversion unclear. Here, we ask whether 4- to 9-year-old children and...

A Data-driven Approach to Crosslinguistic Structural Biases

Data from: Does older adults' cognitive function disrupt the malleability of their attitudes toward outgroup members?: an fMRI investigation

Anne C. Krendl & Elizabeth A. Kensinger
In the current study we examine how individual differences in older adults’ global cognitive function impacts the extent to which their attitudes toward stigmatized individuals are malleable. Because prior research has elucidated the neural processes that are involved in evaluating stigmatized individuals who are responsible or not responsible for their condition, a cognitive neuroscience approach may be well-suited to answer this question. In the current study, 36 older and 17 young adults underwent functional magnetic...

Data from: Baby fish working out: an epigenetic source of adaptive variation in the cichlid jaw

Yinan Hu & R. Craig Albertson
Understanding the developmental processes that underlie the production of adaptive variation (i.e. the ‘arrival of the fittest’) is a major goal of evolutionary biology. While most evo-devo studies focus on the genetic underpinnings of adaptive phenotypic variation, factors beyond changes in nucleotide sequence can also play a major role in shaping developmental outcomes. Here, we document a vigorous but enigmatic gaping behaviour during the early development of Lake Malawi cichlid larvae. The onset of the...

Notochord vacuoles absorb compressive bone growth during zebrafish spine formation

Jennifer Bagwell, James Norman, Kathryn Ellis, Brianna Peskin, James Hwang, Xiaoyan Ge, Stacy Nguyen, Sarah McMenamin, Didier Stanier & Michel Bagnat
The vertebral column or spine assembles around the notochord rod which contains a core made of large vacuolated cells. Each vacuolated cell possesses a single fluid-filled vacuole, and loss or fragmentation of these vacuoles in zebrafish leads to spine kinking. Here, we identified a mutation in the kinase gene dstyk that causes fragmentation of notochord vacuoles and a severe congenital scoliosis-like phenotype in zebrafish. Live imaging revealed that Dstyk regulates fusion of membranes with the...

Data from: microCT-based phenomics in the zebrafish skeleton reveals virtues of deep phenotyping in a distributed organ system

Matthew Hur, Charlotte A. Gistelinck, Philippe Huber, Jane Lee, Marjorie H. Thompson, Adrian T. Monstad-Rios, Claire J. Watson, Sarah K. McMenamin, Andy Willaert, David M. Parichy, Paul Coucke & Ronald Y. Kwon
Phenomics, which ideally involves in-depth phenotyping at the whole-organism scale, may enhance our functional understanding of genetic variation. Here, we demonstrate methods to profile hundreds of phenotypic measures comprised of morphological and densitometric traits at a large number of sites within the axial skeleton of adult zebrafish. We show the potential for vertebral patterns to confer heightened sensitivity, with similar specificity, in discriminating mutant populations compared to analyzing individual vertebrae in isolation. We identify phenotypes...

Identification of Random Resource Shares in Collective Households Without Preference Similarity Restrictions

Geoffrey Dunbar, Arthur Lewbel & Krishna Pendakur
Resource shares, defined as the fraction of total household spending going to each person in a household, are important for assessing individual material well-being, inequality and poverty. They are difficult to identify because consumption is measured typically at the household level, and many goods are jointly consumed, so that individual-level consumption in multi-person households is not directly observed. We consider random resource shares, which vary across observationally identical households. We provide theorems that identify the...

Data from: ddRAD‐seq data reveal significant genome‐wide population structure and divergent genomic regions that distinguish the mallard and close relatives in North America

Philip Lavretsky, Jeffrey M. DaCosta, Michael D. Sorenson, Kevin G. McCracken & Jeffrey L. Peters
Recently evolved species typically share genetic variation across their genomes due to incomplete lineage sorting and/or ongoing gene flow. Given only subtle allele frequency differences at most loci and the expectation that divergent selection may affect only a tiny fraction of the genome, distinguishing closely related species based on multi‐locus data requires substantial genomic coverage. In this study, we used ddRAD‐seq to sample the genomes of five recently diverged, New World “mallards” (Anas spp.), a...
