Download full textChristensen, Doug – Bioscene: Journal of College Biology Teaching, 2009
An inexpensive and equipment free approach to teaching the technical aspects of DNA sequencing. The activity described requires an instructor with a familiarity of DNA sequencing technology but provides a straight forward method of teaching the technical aspects of sequencing in the absence of expensive sequencing equipment. The final sequence…

Direct linkChandramouli, Magesh; Bertoline, Gary; Connolly, Patrick – Engineering Design Graphics Journal, 2009
This study proposes an innovative solution to the problem of multiobjective engineering design optimization by integrating desktop VR with genetic computing. Although, this study considers the case of construction design as an example to illustrate the framework, this method can very much be extended to other engineering design problems as well.…

Erickson, Craig A.; Mullett, Jennifer E.; McDougle, Christopher J. – Journal of Autism and Developmental Disorders, 2009
Glutamatergic dysfunction is implicated in the pathophysiology of fragile X syndrome (FXS). The purpose of this pilot study was to examine the effectiveness and tolerability of memantine for a number of target symptoms associated with FXS. Medical records describing open-label treatment with memantine in 6 patients with FXS and a comorbid…

Ponder, Monica A.; Sumner, Susan – Biochemistry and Molecular Biology Education, 2009
Mock outbreaks of infectious disease offer the ability to introduce principles of food microbiology, ecology, and epidemiology to undergraduate students using an inquiry driven process. Students were presented with an epidemiological case study detailing patient history, clinical presentation, and foods recently consumed. The students then had to…

Oliver, Chris; Woodcock, Kate A.; Humphreys, Glyn W. – Journal of Applied Research in Intellectual Disabilities, 2009
Background: Repetitive questions and temper outbursts form part of the behavioural phenotype of Prader-Willi syndrome (PWS). We investigated the phenomenology of temper outbursts in PWS and their relationship with other PWS behavioural characteristics. Method: Four individuals with PWS were observed (5-10 h), during a number of experimental and…

Cicchetti, Dante; Rogosch, Fred A. – New Directions for Child and Adolescent Development, 2009
The study of resilience in maltreated children reveals the possibility of coping processes and resources on multiple levels of analysis as children strive to adapt under conditions of severe stress. In a maltreating context, aspects of self-organization, including self-esteem, self-reliance, emotion regulation, and adaptable yet reserved…

Background: Mothers' positive emotions expressed about their children with attention deficit/hyperactivity disorder (ADHD) are associated with a reduced likelihood of comorbid conduct problems (CP). We examined whether this association with CP, and one with emotional problems (EMO), is moderated by variants within three genes, previously reported…

Finkelman, Matthew; Kim, Wonsuk; Roussos, Louis A. – Journal of Educational Measurement, 2009
Much recent psychometric literature has focused on cognitive diagnosis models (CDMs), a promising class of instruments used to measure the strengths and weaknesses of examinees. This article introduces a genetic algorithm to perform automated test assembly alongside CDMs. The algorithm is flexible in that it can be applied whether the goal is to…

Spilkin, Amy M.; Ballantyne, Angela O.; Trauner, Doris A. – Neuropsychologia, 2009
Visual and verbal learning in a genetic metabolic disorder (cystinosis) were examined in the following three studies. The goal of Study I was to provide a normative database and establish the reliability and validity of a new test of visual learning and memory (Visual Learning and Memory Test; VLMT) that was modeled after a widely used test of…

Gerrard, Sue; Rugg, Gordon – Journal of Autism and Developmental Disorders, 2009
Sensory impairments are widely reported in autism, but remain largely unexplained by existing models. This article examines Kanner's causal reasoning and identifies unsupported assumptions implicit in later empirical work. Our analysis supports a heterogeneous causal model for autistic characteristics. We propose that the development of a…

Brody, Gene H.; Beach, Steven R. H.; Philibert, Robert A.; Chen, Yi-fu; Lei, Man-Kit; Murry, Velma McBride; Brown, Anita C. – Journal of Consulting and Clinical Psychology, 2009
The authors used a longitudinal, prospective design to investigate a moderation effect in the association between a genetic vulnerability factor, a variable nucleotide repeat polymorphism in the promoter region of "5HTT" (5-HTTLPR), and increases in youths' substance use. The primary study hypothesis predicted that involved-supportive…

Levy, Yonata; Ebstein, Richard P. – Journal of Child Psychology and Psychiatry, 2009
The inherent imprecision of behavioral phenotyping is the single most important factor contributing to the failure to discover the biological factors that are involved in psychiatric and neurodevelopmental disorders (e.g., Bearden & Freimer, 2006). In this review article we argue that in addition to an appreciation of the inherent complexity at…

D'Onofrio, Brian M.; Goodnight, Jackson A.; Van Hulle, Carol A.; Rodgers, Joseph Lee; Rathouz, Paul J.; Waldman, Irwin D.; Lahey, Benjamin B. – Journal of Abnormal Child Psychology, 2009
The study presents a quasi-experimental analysis of data on 9,194 offspring (ages 4-11 years old) of women from a nationally representative U.S. sample of households to test the causal hypotheses about the association between family income and childhood conduct problems (CPs). Comparison of unrelated individuals in the sample indicated a robust…

Matson, Johnny L.; LoVullo, Santino V. – Research in Autism Spectrum Disorders, 2009
The field of autism spectrum disorders (ASDs) is expanding at an exponential rate. New topics for study are forming and journals are emerging rapidly to handle the ever-increasing volume of publications. This study was undertaken to provide an overview of past and current research trends. Representative studies were evaluated for type of content…

Coleman, Toni – Diverse: Issues in Higher Education, 2007
Increasingly, Blacks are turning to science and not assumptions to put "Africa" back in "African-American." The eagerness to reconnect is understandable. People robbed of their history innately want to know where they come from. Blacks are now using DNA testing to determine their African lineage. Veteran genealogists say the…
