Evaluation Of Proficiency Testing Program For Laboratories Conducting Hiv-1 Dna Detection For Early Infant Diagnosis From Dried Blood Spot Specimens In Resource-Limited Settings, Albert D. Garcia

Public Health Theses

Early diagnosis of HIV in infants is critical because it can remarkably impact an infant’s survival. DNA PCR is the standard test for diagnosis of HIV-1 in infants and young children less than 18 months of age. For settings that lack the adequate infrastructure for processing whole blood and cold-chain transportation, the collection of dried blood spots (DBS) has facilitated the detection of HIV-1 in infants as early as 4-6 weeks after birth. Molecular testing using DBS provides an accurate method for the identification of HIV-1 but quality testing depends greatly on adequate quality assurance. A voluntary, cost-free external quality …

5- And 8-Month-Olds’ Visual Exploration Of 2d Scenes: The Relative Impact Of Object Size, Object Detail, And Depth Cue On Infants’ Visual Attention, Yu Guan

Doctoral Dissertations

How infants visually explore complex scenes containing objects varying in size, depth cues, and amount of detail is still an open question. When infants are presented with a complex scene, we do not know which dimensions of the scene are more likely to catch their attention first, and which are more likely to sustain their looking duration the most. This study aimed to investigate how infants’ explore 2D displays containing different combinations of object size, depth cues, and detail.

In experiment 1, forty infants (twenty of 5 months old and twenty of 8 months old) were presented with stimuli containing …

Maternal Depression In A Racially And Socioeconomically Diverse Cohort: Influences On Infant Feeding Practices., Lauren M. Sims

Electronic Theses and Dissertations

Feeding practices during infancy and early childhood have lifelong effects on weight and relationships with food. With the growing prevalence of obesity in adults and children, early feeding practices are being examined more carefully as points in which public health interventions may be successful. Experts recommend that feeding practices be responsive in nature. Maternal depression has been shown to have deleterious effects on parenting practices, contributing to their unresponsiveness. As the responsive frameworks for parenting and feeding are similar, we expected to find similar effects of maternal depression on feeding practices. Maternal depression does, in fact, contribute to unresponsive feeding …

Infants’ Responses To Affect In Music And Speech, Daniel K. Feinberg

Pitzer Senior Theses

Existing literature demonstrates that infants can discriminate between categories of infant-directed (ID) speech based on the speaker’s intended message – that is, infants recognize the difference between comforting and approving ID speech, and treat different utterances from within these two categories similarly. Furthermore, the literature also demonstrates that infants understand many aspects of music and can discriminate between happy and sad music. Building on these findings, the present study investigated whether exposure to happy or sad piano music would systematically affect infants’ preferences for comforting or approving ID speech. Five- to nine-month-old infants’ preferences for comforting or approving ID speech …

Infant Perceptions Of Mixed-Race Faces: An Exploration Of The Hypodescent Rule In 8.5 Month-Old Infants, Sophie Beiers

Pitzer Senior Theses

Studies have shown that adults often categorize mixed-race individuals of White and non-White descent as members of the non-White racial group, an effect said to be reminiscent of the “hypodescent” or “one-drop rule.” This effect has not yet been thoroughly studied in infants, although 9-month-old infants have been shown to be able to categorize mono-racial faces into different racial groups. In the present study, the perception of mixed-race White and Asian/Asian American faces was studied in sixteen 8.5-month-old infants. The infants were randomly assigned to two stimulus groups. The stimuli were the photographed faces of female college students who had …

Benefits Of Baby Sign On Cognitive Development In Infants, Clarissa Navedo

Open Access Theses & Dissertations

Research in the area of baby sign language has increased dramatically over the past several years, however there is still a lack of research regarding baby signs effects on typical infant development, specifically in the area of cognition. The hypothesis of this study was that instruction of baby sign would be correlated with a significant increase in the development of cognition and language acquisition for infant participants. This study provided a five-week instructional course on baby sign for parents/caregivers to implement with their typically developing infants (n=11). The course provided instruction of baby signs, methods of implementation and encouragement to …

A Grounded Theory Model Of Mother Role Development While In The Neonatal Intensive Care Unit, Kathy B. Isaacs

Theses and Dissertations--Nursing

When a woman discovers that she is pregnant, she begins a process of internal work to develop her mother role. This process has been outlined in the literature for the delivery of a healthy full-term baby, however little is known about the process for mothers of medically fragile babies. A threatened pregnancy and subsequent delivery of a medically fragile baby involves a different process of internal work by the mother to prepare for her role. Mothers with a baby in the Neonatal Intensive Care Unit (NICU) experience stress, uncertainty, and anxiety potentially causing a permanent impact on the successful development …

Validation Of The Remote Food Photography Method To Quantify Intake Of Infant Formula, Abby Duhe

LSU Master's Theses

Childhood obesity rates have more than tripled since the 1970s, and this increased prevalence is cause for concern as childhood obesity increases the risk of adult obesity and other comorbid diseases. Evidence suggests that the origins of obesity can be identified in infanthood. Accurate methods of assessing food intake in infants can be utilized to establish effective feeding practices in infanthood and to assess the relationship between infant feeding practices and the risk of childhood obesity. Current methods are either subjective or have limited ability for widespread use beyond clinical research settings due to cost and high burden. The aim …
