ABSTRACT Deciding what to eat can be difficult. There are multiple different diets which are popular today, and all of them say different things about which foods optimize health, and which foods are destructive. The situation become more complicated when the suggestions are all purportedly based on relevant science, and all have had demonstrated positive impacts on overall wellbeing. Even when we do have good information, financial factors, geography, and time constraints can prevent us from acting on it. In an attempt to portray the difficulties involved in eating well, I start by analyzing what each of six diets - The Paleo Diet, The Perfect Health Diet, the vegetarian diet, the vegan diet, the Mediterranean Diet, and the Traditional Asian Diet - says about what we should be eating. I then explore what the science says about what we should be eating, and whether this science lines up with the diets, by discussing an extensive review of books and literature on nutrition. Lastly, in order to gain an understanding of factors which discourage us from eating well, I tracked my consumption habits for a week using My Fitness Tracker, and noted any reasons that I chose to eat or not eat certain foods. I supplemented this with a discussion of the shortcomings of the Healthy, Hunger-Free Kids Act, and the types of factors that prevent people from acting on information. In conclusion, diets should be praised for attempting to align American eating habits with the best scientific information, but the vast amount of information and the difficulty involved in eating well may ultimately prevent people from doing so.

Description
This study aims to unearth monological and monocultural discourses buried under the power of the dominant biomedical model governing the HIV/AIDS debate. The study responds to an apparent consensus, rooted in Western biomedicine and its "standardizations of knowledge," in the production of the current HIV/AIDS discourse, especially in Sub-Saharan Africa. As a result, biomedicine has become the dominant actor (in) writing and rewriting discourse for the masses while marginalizing other forms of medical knowledge. Specifically, in its development, the Western biomedical model has arguably isolated the disease from its human host and the social experiences that facilitate the disease's transmission, placing it in the realm of laboratories and scientific experts and giving full ownership to Western medical discourse. Coupled with Western assumptions about African culture that reproduce a one-sided discourse informing the social construction of HIV/AIDS in Africa, this Western monopoly thus constrained the extent and efficacy of international prevention efforts. In this context, the goal for this study is not to demonize the West and biomedicine in general. Rather, this study seeks an alternative and less monolithic understanding currently absent in scientific discourses of HIV/AIDS that frequently elevates Western biomedicine over indigenous medicine; the Western expert over the local. The study takes into account the local voices of Sub-Saharan Africa and how the system has affected them, this study utilizes a Foucauldian approach to analyze discourse as a way to explore how certain ways of knowledge are formed in relation to power. This study also examines how certain knowlege is maintaned and reinforced within specific discourses.

Description
This is a project about medicine and the history of a condition called premenstrual syndrome (PMS), its “discovery” and conceptual development at both scientific and socio-cultural levels. Since it was first mentioned in medical literature, PMS has been explored empirically as a medical condition and conceptually as non-somatic cultural phenomenon. Many attempts have been made to produce scientific, empirical evidence to bolster the theory of PMS as a biological disease. Some non-medical perspectives argue that invoking biology as the cause of PMS medicalizes a natural function of the female reproductive system and shallowly interrogates what is actually a complex bio-psycho-social phenomenon. This thesis questions both sides of this debate in order to reveal how criteria for PMS were categorized despite disagreement surrounding its etiology.
This thesis illustrates how the concept of PMS developed and was informed by the discovery of hormones and the resulting field of endocrinology that provided a framework for conceptualizing PMS. It displays how the development of the medical diagnostic category of PMS developed in tandem with the emergence of the field of endocrinology and was legitimized and effectively medicalized through this connection. The diagnosis of PMS became established though the diagnostic techniques like questionnaires in spite of persistent disagreement over its definition. The thesis shows how these medical concepts and practices legitimated the category of PMS, and how it has become ubiquitous in contemporary culture.

Description
Prior to the first successful allogeneic organ transplantation in 1954, virtually every attempt at transplanting organs in humans had resulted in death, and understanding the role of the immune mechanisms that induced graft rejection served as one of the biggest obstacles impeding its success. While the eventual achievement of organ transplantation is touted as one of the most important success stories in modern medicine, there still remains a physiological need for immunosuppression in order to make organ transplantation work. One such solution in the field of experimental regenerative medicine is interspecies blastocyst complementation, a means of growing patient-specific human organs within animals. To address the progression of immune-related constraints on organ transplantation, the first part of this thesis contains a historical analysis tracing early transplant motivations and the events that led to the discoveries broadly related to tolerance, rejection, and compatibility. Despite the advancement of those concepts over time, this early history shows that immunosuppression was one of the earliest limiting barriers to successful organ transplantation, and remains one of the most significant technical challenges. Then, the second part of this thesis determines the extent at which interspecies blastocyst complementation could satisfy modern technical limitations of organ transplantation. Demonstrated in 2010, this process involves using human progenitor cells derived from induced pluripotent stem cells (iPSCs) to manipulate an animal blastocyst genetically modified to lack one or more functional genes responsible for the development of the intended organ. Instead of directly modulating the immune response, the use of iPSCs with interspecies blastocyst complementation could theoretically eliminate the need for immunosuppression entirely based on the establishment of tolerance and elimination of rejection, while also satisfying the logistical demands imposed by the national organ shortage. Although the technology will require some further refinement, it remains a promising solution to eliminate the requirement of immunosuppression after an organ transplant.

Description
This thesis reviews the initial cases of fetal surgery to correct myelomeningocele, a severe form of spina bifida, and discusses the human and social dimensions of the procedure. Myelomeningocele is a fetal anomaly that forms from improper closure of the spinal cord and the tissues that surround it. Physicians perform fetal surgery on a developing fetus, while it is in the womb, to mitigate its impacts. Fetal surgery to correct this condition was first performed experimentally in the mid-1990and as of 2020, it is commonly performed. The initial cases illuminated important human and social dimensions of the technique, including physical risks, psychological dimensions, physician bias, and religious convictions, which affect decision-making concerning this fetal surgery. Enduring questions remain in 2020. The driving question for this thesis is: given those human and social dimensions that surround fetal surgery to correct myelomeningocele, whether and when is the surgery justified? This thesis shows that more research is needed to answer or clarify this question.

Description
The landscape of science education is changing. Scientific research and the academy are both becoming increasingly complex, competitive, interdisciplinary, and international. Many federal research agencies, scientific professional societies, and science educators seem to agree on the importance of strong ethics education to help young scientists navigate this increasingly craggy terrain. But, what actually should be done? When it comes to teaching ethics to future scientists, is the apparent current emphasis on basic responsible conduct of research (RCR) sufficient, or should moral theory also be taught in science ethics education? In this thesis I try engage this question by focusing on an existing, related debate on whether moral theory should be part of teaching professional ethics more generally. After delving into the respective approaches promoted by the three primary participants in this debate (C. E. Harris, Bernard Gert, and Michael Davis) I unpack their views in order to ascertain their practical application potential and relative benefits. I then take these findings and apply them to ethics education in science, paying particular attention to its purported learning objectives. In the end I conclude that the presentation of these objectives suggests that moral theory may well be required in order for these objectives of ethics education in science to be fully achieved.
