Description
The advent of advanced reproductive technologies has sparked a number of ethical concerns regarding the practices of reproductive tourism and commercial gestational surrogacy. In the past few decades, reproductive tourism has become a global industry in which individuals or couples travel, usually across borders, to gain access to reproductive services. This marketable field has expanded commercial gestational surrogacy--defined by a contractual relationship between an intending couple and gestational surrogate in which the surrogate has no genetic tie to fetus--to take on transnational complexities. India has experienced extreme growth due to a preferable combination of western educated doctors and extremely low medical costs. However, a slew of ethical issues have been brought to the forefront: the big ones manifesting as concern for reduction of a woman's worth to her reproductive capabilities along with concern for exploitation of third world women. This project will be based exclusively on literature review and serves primarily as a call for cultural competency and understanding the circumstances that gestational surrogates are faced with before implementing policy regulating commercial gestational surrogacy. The paper argues that issues of exploitation and commodification hinge on constructions of motherhood. It is critical to define and understand definitions of motherhood and how these definitions affect a woman's approach to reproduction within the cultural context of a gestational surrogate. This paper follows the case study of the Akanksha Infertility Clinic in northern India, a surrogacy clinic housing around 50 Indian surrogates. The findings of the project invokes the critical significance of narrative ethics, which help Indian surrogates construct the practice of surrogacy so that it fits into cultural comprehensions of Indian motherhood--in which motherhood is selfless, significant, and shared.

Description
A dental exam in twenty-first century America generally includes the taking of radiographs, which are x-ray images of the mouth. These images allow dentists to see structures below the gum line and within the teeth. Having a patient's radiographs on file has become a dental standard of care in many states, but x-rays were only discovered a little over 100 years ago. This research analyzes how and why the x-ray image has become a ubiquitous tool in the dental field. Primary literature written by dentists and scientists of the time shows that the x-ray was established in dentistry by the 1950s. Therefore, this thesis tracks the changes in x-ray technological developments, the spread of information and related safety concerns between 1890 and 1955. X-ray technology went from being an accidental discovery to a device commonly purchased by dentists. X-ray information started out in the form of the anecdotes of individuals and led to the formation of large professional groups. Safety concerns of only a few people later became an important facet of new devices. These three major shifts are described by looking at those who prompted the changes; they fall into the categories of people, technological artifacts and institutions. The x-ray became integrated into dentistry as a product of the work of people such as C. Edmund Kells, a proponent of dental x-rays, technological improvements including faster film speed, and the influence of institutions such as Victor X-Ray Company and the American Dental Association. These changes that resulted established a strong foundation of x-ray technology in dentistry. From there, the dental x-ray developed to its modern form.

Description
Within ethics, a number of scholars advocate an interdisciplinary approach of combining the two traditionally different professions of science and philosophy with the confidence that this collaboration will be a mutually beneficial experience. Current ethicist-scientist interactions include embedded-ethicists and research ethics consultation services. Both methods are employed with the hope that they will reduce social and ethical problems that could arise from scientific research, and enhance the reflective capacity of investigative teams. While much effort has been put forth in the endeavor of creating ethicist-scientist interactions, there remains opportunity to refine these new interaction models to make them more robust. There is need for ethicists to understand the context of ethical decision-making in the laboratory. By extension, before interacting with scientists in a research lab, research ethicists ought to have the ability to understand the science and also be familiar with the different factors that influence scientific research, such as funding, productivity requirements, time constraints, politics of laboratories and institutional reward structures. Through literature review and the analysis of qualitative data obtained from the ethnographic study in a neuroscience laboratory, this thesis explores the strengths and weaknesses of ethicist-scientist interactions and aims to understand the culture, traditions and values of this community and their perspectives on their role as scientists and their relationship to ethics. This study shows that the quantity and quality of ethics discussions in the lab are limited and dictated by time constraints and minimal incentives. Other influencing factors are the researchers' perspectives on ethics and how they view their role as a scientist in relation to the public.

Description
Despite the minor differences in the inclusiveness of the word, there is a general assumption among the scientific community that the 'pursuit of knowledge' is the most fundamental element in defining the word 'science'. However, a closer examination of how science is being conducted in modern-day South Korea reveals a value system starkly different from the value of knowledge. By analyzing the political discourse of the South Korean policymakers, mass media, and government documents, this study examines the definition of science in South Korea. The analysis revealed that the Korean science, informed by the cultural, historical, and societal contexts, is largely focused on the values of national economic prosperity, international competitiveness, and international reputation of the country, overshadowing other values like the pursuit of knowledge or even individual rights. The identification of the new value system in South Korean science deviating from the traditional definition of science implies that there must be other definitions of science that also deviates, and that even in the Western world, the definition of science may yield similar deviations upon closer examination. The compatibility of the South Korean brand of science to the international scientific community also implies that a categorical quality is encompassing these different contextual definitions of science.

Whistleblowing in Biomedical Research and Medicine: An Analysis of Ethical Expectations and Dilemmas
Description
In biomedical research institutions and medical institutions alike, whistleblowing, or the reporting of misconduct, has been severely retaliated against. Whistleblowers report misconduct by adhering to institutional whistleblowing policies, and do so in order to maintain ethical practice within their institution; it is important to note that by taking this ethical action, whistleblowers are aiming to protect the future of biomedical research and medicine. Despite these intentions, whistleblowing has developed a negative stigma due to the misconception that whistleblowers have self-proclaimed authority and are unable to function as part of a team. The retaliation against whistleblowers has been connected to psychological and professional fallout for the whistleblower, and it has been found that many whistleblowers suffer as a direct result of a lack of institutional support. The problems with whistleblowing culture demonstrate issues surrounding how ethics are maintained in institutions, who ethics policies apply to, and who has authority. The retaliation seen against whistleblowers outlines inherent institutional failures, and highlights the need for institutional change in order to both promote ethical practice and protect the whistleblowers who adhere to ethics policies. This thesis discusses such failures in detail, and outlines several broad solutions in order to combat this issue.

Description
Contraceptives are a vital part of reproductive care by preventing unwanted pregnancy, providing relief to premenstrual syndrome or PMS symptoms, and more. Birth control has been around for many centuries and has given women autonomy over their reproductive health. The Griswold v. Connecticut Supreme Court case in 1965 was the first ruling that made birth control accessible to the public under the law. However, this ruling only pertained only to married couples until the Eisenstadt v. Baird case in 1972. That case gave single women the ability to legally purchase contraceptives for themselves. In the decades since those rulings, many laws and policies have been put into place to give those in lower-income areas the ability to purchase contraceptives as well. With this increase in accessibility, those who use contraceptives, or are thinking of starting birth control, need to understand how to use it, when to use it, and the effects of using contraceptives. In the United States, nurses outnumber doctors by a 4:1 ratio and spend more time with patients than anyone else in a clinic or hospital environment. Nurses, being the main healthcare providers with whom a patient will interact, often are the ones patients ask questions about care and overall advice. Nurses must be able to relay valuable information about treatments or medicines, such as birth control, and give accurate information on the effects such treatments have. Nursing students need to be prepared. However, the amount of information provided, and opinions given might be affected by their nursing education, past experiences with birth control, and more. This project surveys nursing students at Arizona State University on their attitudes, behaviors, and beliefs towards birth control interventions, and how their individual experiences and education influence these perceptions.

Description
Advocacy groups work across many aspects of “death with dignity” practice and treatment, and provide insight across multiple aspects of “death with dignity”. This study argues that key advocacy groups in the American death with dignity movement influenced the broader conceptualization of death with dignity in a way that makes patients more able to achieve it. This influence has been a dynamic process across different periods of practice starting the discussion of “death with dignity” in 1985 through today, although this thesis extends only to 2011. The question in this study is how do the three main historical advocacy groups in the US: the Hemlock Society, Compassion in Dying, and Compassion and Choices, conceptualize death with dignity with regards to patient and doctor relationship, legal and policy factors, and medical technologies and protocols? This study found that the Hemlock Society (1980-2005) characterized death with dignity as a terminally ill patient being able to “self-deliver” from suffering via autoeuthanasia regardless of medical community approval or legality. Compassion in Dying (1993-2007) characterized death with dignity as involved advocacy work with terminal patients and their communities to pursue palliative care and hospice up to the point of assisted death. This organization was also involved in the passing of Oregon Death with Dignity Act. Compassion and Choices (2007-present) characterized death with dignity similarly to Compassion in Dying but also advocated for adequate management of pain and suffering symptoms in palliative care to prevent people from desiring death over the illness. Conceptualizing death with dignity is important for understanding why patients want death with dignity and better accommodating their end of life needs when they are suffering with terminal illness.

Access to testing for the human immunodeficiency virus (HIV), as well as other care services related to HIV/AIDS, have greatly improved in Tanzania over the last decade. Despite the country’s efforts to increase the number of individuals who get tested for HIV annually, it is estimated that only 52.2-70.0% of people living with HIV (PLWH) knew their HIV positive status at the end of 2017. In addition, research in Tanzania has shown that HIV-related stigma and discrimination are widespread and contribute to low uptake of HIV testing and non-adherence to antiretroviral treatment (ART). In order to achieve the goals set forth by the Government of Tanzania and the Joint United Nations Programme on HIV/AIDS (UNAIDS), as well as move towards an AIDS-free generation, a deeper understanding of the stigma-related barriers to seeking an HIV test is necessary. This research aims to better understand the relationship between HIV-related stigma and attitudes towards HIV testing among community members in Northern Tanzania. In addition, it looked at the specific barriers that contribute to low uptake of HIV testing, as well as the impact of social networks on an individual’s motivation and willingness to get tested for HIV. In this research, community members in Meru District (N = 108, male = 69.4%, female = 28.7%) were surveyed using various validated instruments that covered a range of topics, including knowledge of HIV/AIDS, testing attitudes, and perceived risk of HIV infection. The mean overall score for correct answers on the knowledge measure was 69.8% (SD = 16.4). There were no significant group differences between individuals who had ever tested and individuals who had not tested in relation to HIV/AIDS knowledge or HIV testing attitudes. The factors that were significantly associated with getting an HIV test were knowing someone who had previously tested (p = 0.003), as well as openly discussing HIV testing within one’s social group (p = 0.017). Participants also provided qualitative responses for barriers to receiving an HIV test, motivations for getting tested, and suggested interventions for improving HIV testing uptake. The goal of this research is to develop recommendations for interventions that are better informed by attitudes and motivations for testing.

Description
Systems biology studies complex biological systems. It is an interdisciplinary field, with biologists working with non-biologists such as computer scientists, engineers, chemists, and mathematicians to address research problems applying systems’ perspectives. How these different researchers and their disciplines differently contributed to the advancement of this field over time is a question worth examining. Did systems biology become a systems-oriented science or a biology-oriented science from 1992 to 2013?
This project utilized computational tools to analyze large data sets and interpreted the results from historical and philosophical perspectives. Tools deployed were derived from scientometrics, corpus linguistics, text-based analysis, network analysis, and GIS analysis to analyze more than 9000 articles (metadata and text) on systems biology. The application of these tools to a HPS project represents a novel approach.
The dissertation shows that systems biology has transitioned from a more mathematical, computational, and engineering-oriented discipline focusing on modeling to a more biology-oriented discipline that uses modeling as a means to address real biological problems. Also, the results show that bioengineering and medical research has increased within systems biology. This is reflected in the increase of the centrality of biology-related concepts such as cancer, over time. The dissertation also compares the development of systems biology in China with some other parts of the world, and reveals regional differences, such as a unique trajectory of systems biology in China related to a focus on traditional Chinese medicine.
This dissertation adds to the historiography of modern biology where few studies have focused on systems biology compared with the history of molecular biology and evolutionary biology.

Description
Researchers in the twentieth and twenty-first centuries identify the study of the intrinsic and external factors that influence human aging as senescence. A commonly held belief in the year 2015 is that at least some kinds of cells can replicate over long periods or even indefinitely, thereby meaning the cell does not undergo senescence (also known as replicative senescence) and is considered immortal. This study aims to provide information to answer the following question: While some scientists claim they can indefinitely culture a stem cell line in vitro, what are the consequences of those culturing practices? An analysis of a cluster of articles from the Embryo Project Encyclopedia provides information to suggest possible solutions to some potential problems in cell culturing, recognition of benefits for existing or historical culturing practices, and identification of gaps in scientific knowledge that warrant further research. Recent research suggests that hESCs, and immortalized cell lines in general, do not escape the effects of senescence. While there exists a constant change in the practices of cell culturing, a large portion of scientists still rely on practices established before modern senescence research: research that seems to suggest that cultured hESCs, among other immortal cell lines, are not truly immortal.
