Genetics literacy is becoming increasingly important as advancements in our application of genetic technologies such as stem cell research, cloning, and genetic screening become more prevalent. Very few studies examine how genetics literacy is applied when reasoning about authentic genetic dilemmas. However, there is evidence that situational…

Five factors (gender, handedness, some aspects of general health, family history, and intelligence) that could assist speech-language pathologists in identification of children who stutter (CWS) in 42 CWS and 34 fluent control children (children who do not stutter [CWNS]) were investigated. The data reported here were obtained from assessments…

Sleep deprivation (SD) following hippocampus-dependent learning in young mice impairs memory when tested the following day. Here, we examined the effects of SD on remote memory in both young and aged mice. In young mice, we found that memory is still impaired 1 mo after training. SD also impaired memory in aged mice 1 d after training, but, by a…

For many students, the experience with science tends to be alienating and uprooting. In this study, I take up Simone Weil's concepts of "enracinement" (rooting) and "déracinement" (uprooting) to theorize the root of this alienation, the confrontation between children's familiarity with the world and unfamiliar/strange…

The Study to Explore Early Development (SEED) is a multi-site case-control study designed to explore the relationship between autism spectrum disorder (ASD) phenotypes and etiologies. The goals of this paper are to (1) describe the SEED algorithm that uses the Autism Diagnostic Interview-Revised (ADI-R) and Autism Diagnostic Observation Schedule…

Autism spectrum disorders (ASD) and attention-deficit/hyperactivity disorder (ADHD) are highly heterogeneous neuropsychiatric disorders, that frequently co-occur. This study examined whether stratification into single-incidence (SPX) and multi-incidence (MPX) is helpful in (a) parsing heterogeneity and (b) detecting overlapping and unique…

Recent studies have begun to uncover the genetic architecture of educational attainment. We build on this work using genome-wide data from siblings in the National Longitudinal Study of Adolescent to Adult Health (Add Health). We measure the genetic predisposition of siblings to educational attainment using polygenic scores. We then test how…

Indigenous slavery was a critical aspect of New Mexican life and culture during the Spanish, Mexican, and early American (Territorial) periods. Aside from the labor and military support provided by indigenous slaves for the expansion of the province, the genetic contribution to the population growth was enormous. Ramón Gutiérrez (1991) speculates…

The credibility of conclusions made about the effectiveness of educational interventions depends greatly on the quality of the assessments used to measure learning gains. This essay, intended for faculty involved in small-scale projects, courses, or educational research, provides a step-by-step guide to the process of developing, scoring, and…

In communities with an increased prevalence of hereditary deafness, social, and linguistic adaptations are found in response. Aulbers (1959) describes a high prevalence of deafness in a fishing village on the Dutch coast: Katwijk aan Zee. This article aims to assess the current prevalence of deafness in Katwijk, as well as the current sign…

Given the underrepresentation of ethnic minorities in health research (Heiat et al. in "Arch Int Med" 162(15):1-17, 2002; Kelly et al. in "J Nat Med Assoc" 97:777-783, 2005; United States Department of Health and Human Services. "Monitoring adherence to the NIH policy on the inclusion of women and minorities as subjects in…

There are strong classroom ties between mathematics and the sciences of physics and chemistry, but those ties seem weaker between mathematics and biology. Practicing biologists realize both that there are interesting mathematics problems in biology, and that viewing classroom biology in the context of another discipline could support students'…

Various theorists have argued for the importance of a developmental approach to studying typical development (Karmiloff-Smith, 1998; Lerner, 1996; Lerner & Hood, 1986; Masten & Cicchetti, 2010; Overton, 2014; Overton & Lerner, 2012, 2014), and there are reasons to believe that this issue is even more critical to the study of…

The presented research hypothesis-driven laboratory exercise teaches advanced undergraduate students state of the art methods and thinking in an integrated molecular physiology context. Students understand the theoretical background of iron acquisition in the model plant "Arabidopsis thaliana." They design a flowchart summarizing the key…

Childhood abuse can alter biological systems and increase risk for adult psychopathology. Epigenetic mechanisms, alterations in DNA structure that regulate the gene expression, are a potential mechanism underlying this risk. While abuse associates with methylation of certain genes, particularly those in the stress response system, no study to date…
