The use of infant locomotor devices such as walkers, jumpers, and exersaucers are widely controversial amongst parents and pediatricians. Parents often cite benefits to the child with device exposure, whereas pediatricians often warn against the use of them. The concern of the pediatricians lay within the risk that comes along with increased mobility, as well as the upright position the device puts the child in. The child is often unable to place themselves in this position outside of the device due to not being ready in their developmental pathway. The device places the child upright with their legs hanging below with their feet not flat on the ground supporting weight. This position can place strain on the infants’ hips, lower back, and trunk.
Research shows that infants with prolonged device exposure tend to reach their locomotor milestones later than infants with average to ideal exposure. Infants with prolonged device exposure have also been found to score lower on developmental assessments. To reduce the risk of injury and developmental delay, the American Academy of Pediatrics ban the production and sale of infant walkers, and advised parents allow their children to play in more natural positions, rather than the position the locomotor devices place the child in.
In order to bridge the gap of education provided to parents and caregivers, and the knowledge of the pediatricians, further research should be done to collect up to date data of the impact of these devices and the long-term impact of these devices past the age of three. Working to expand the educational outreach to parents, particularly in the medical setting, would also be beneficial in working to reduce the exposure infants have to these devices and in turn, the number of injuries and developmental delays associated with use.
Breast cancer affects about 12% of women in the US. Arguably, it is one of the most advertised cancers. Mammography became a popular tool of breast cancer screening in the 1970s, and patient-geared guidelines came from the American Cancer Society (ACS) and the US Preventative Task Force (USPSTF). This research focuses on ACS guidelines, as they were the earliest as well as the most changed guidelines. Mammography guidelines changed over time due to multiple factors. This research has tracked possible causes of those changes. Research began with an extensive literature search of clinical trials, the New York Times and the Washington Post archives, systematic reviews, ACS and USPSTF archives.
Science fiction works can reflect the relationship between science and society by telling stories that are set in the future of ethical implications or social consequences of scientific advancements. This thesis investigates how the concept of reproduction is depicted in popular science fiction works.
By questioning methods of sex selection since their early development, and often discovering that they are unreliable, scientists have increased the creative and technological capacity of the field of reproductive health. The presentation of these methods to the public, via published books on timing methods and company websites for sperm sorting, increased interest in, and influence of, sex selection within the global society. The purpose of explaining the history, interest, development, and impact of various sex selection methods in the mid-twentieth century based on the information that is available on them today is to show couples which methods have failed and provide them with the knowledge necessary to make an informed decision on how they choose to go about utilizing methods of sex selection.
By demonstrating the struggle for sound standard of care for non-medical reproductive health care providers during the nineteenth and early twentieth century, this project emphasizes what the standards of reproductive health care for abortion and contraception might be like if the organizations that made them so readily available, like Planned Parenthood, were defunded or criminalized in our modern setting.
