This study aims at examining problematic learning trajectories of students with emotional behavioral disorders (EBD) by means of a longitudinal and time serial (micro genetic) study of individual instruction sessions during arithmetic lessons. Micro genetic analysis techniques were applied on the variable "responsiveness" in the scaffolding…

Objective: College lifestyle places an individual at greater risk for the development of insulin resistance (IR) and disease. The aim of this study was to establish a baseline measurement of insulin, and other variables influencing IR in college freshmen. Participants: Twenty-two men and women, 18 to 19 years of age, during first month of college.…

Depression is a developmental phenomenon. Considerable progress has been made in describing the syndrome, establishing its prevalence and features, providing clues as to its etiology, and developing evidence-based treatment and prevention options. Despite considerable headway in distinct lines of vulnerability research, there is an explanatory gap…

Klinefelter syndrome (47,XXY) was initially described in the context of its endocrinologic and physical features; however, subsequent studies have revealed specific impairments in verbal skills and social functioning. Males with sex chromosomal aneuploidies are known to have variability in their developmental profile with the majority presenting…

Autism is a strongly genetic disorder and de novo mutations may play a causal role in a relatively large percentage of individuals with the disease. It is discussed how altered development may be an important factor that forces diverse genetic vulnerabilities into common syndromic presentation in autism.

Dyslexia is a complex reading and writing disorder with a strong genetic component. In a German case-control cohort, we studied the influence of the suspected dyslexia-associated gene DCDC2. For the first time in a German cohort, we describe association of a 2445 basepair deletion, first identified in an American study. Evidence of association for…

Rett syndrome (RTT) is a rare genetic disorder within the autistic spectrum. This study compared socio-demographic, clinical and genetic characteristics of the international database, InterRett, and the population-based Australian Rett syndrome database (ARSD). It also explored the strengths and limitations of InterRett in comparison with other…

Nowadays, there is a need in science education to consider scientific research and its applications alongside ethical consensus. Even though classroom debates of value issues have been demonstrated to significantly contribute to the raising of social consciousness and awareness, research shows that neither academics in higher education nor…

The American Association for the Advancement of Science 2011 report "Vision and Change in Undergraduate Biology Education" encourages the teaching of developmental biology as an important part of teaching evolution. Recently, however, we found that biology majors often lack the developmental knowledge needed to understand evolutionary…

Cell-free protein synthesis (CFPS) has emerged as a practical method for producing a broad variety of proteins. In addition, the direct accessibility to the reaction environment makes CFPS particularly suitable as a learning vehicle for fundamental biological concepts. Here, we describe its implementation as a teaching tool for a high school…

Research suggests that sibling--peer connections are important for understanding adolescent problem behaviors. Using a novel behavioral genetic design, the current study investigated peer network overlap in 300 child--child pairs (aged 7-13 years) in 5 dyad types: monozygotic (MZ), dizygotic twins, full siblings (FSs), friend pairs, and virtual…

This study used a mixed methods approach to evaluate hybrid peer-assisted learning approaches incorporated into a bioinformatics tutorial for a genome annotation research project. Quantitative and qualitative data were collected from undergraduates who enrolled in a research-based laboratory course during two different academic terms at UCLA.…

The Smithsonian's rich and vast collections differentiate them from every other museum on the planet, but it is their people that truly distinguish them. From astrophysics and American art to sociology and zoology, they represent a staggering breadth of knowledge and depth of commitment, yet the most exciting thing to watch is what happens when…

Prior work has suggested that inter-parental conflict likely plays an etiological role in child behavior problems. However, family-level measurement of inter-parental conflict in most traditional child twin studies has made it difficult to tease apart the specific causal mechanisms underlying this association. The Children's Perception of…

We examined selected situational emotions (interest, well-being and anxiety) experienced by 291 secondary school tenth graders during a hands-on gene technology lesson. Two different instruction groups (I-1, I-2) participated in the same teaching unit, in which four basic gene technology experiments were performed. Using a modified…
