Description
There is a nationwide gap in which African American, Hispanic and low-income students perform significantly lower than their peers. Research suggests that teachers hold lower expectations for these students resulting in lower achievement. There are four main factors that influence teacher expectations: stereotypes, teacher self-efficacy, school culture, language and formal policies and programs aimed at increasing teacher expectations. The purpose of this study was to inquire into the following questions: (1) What are the factors that influence teachers' academic expectations for low-income and minority students? (2) What are teacher's perceptions on the effectiveness of formal policies and programs that are aimed at increasing teacher expectations? More specifically, do teachers feel that top-down formal policies, such as teacher evaluations, uniform curriculum, and performance-based pay are effective in impacting their expectations, or do teachers believe that bottom-up policies, such as book studies and professional learning communities, make more of an impact on increasing their expectations? Ten teachers were interviewed in a school district that is consistent with the state and national achievement gap. The findings revealed that teacher expectations are influenced by the four factors I found in the research as well as two other factors: a cultural disconnect among teachers and students and teachers' level of motivation. A combination of top-down and bottom-up formal policies and programs are needed as teachers are individuals and all respond to various forms of formal policies and programs differently.

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.

Description
It is common for graduate programs to be plagued by delays in on-time student completion or to experience student attrition. Students have experienced such delays in a local program at the University where I am employed as a lecturer. Therefore, this dissertation was undertaken with the aim of supporting university students at the graduate level toward successful on-time completion of their programs. This action research study was multi-phased in its approach; with data collection, and reflection driving the process for intervention delivery and subsequent evaluation. A dynamic approach which included some components of greater structure than was previously seen in the program, was designed for implementation. It was envisaged that this approach would serve as a model of support for students. The following chapters written in article format details the cycles of action research undertaken as part of this dissertation. The first article tells a story written for a wider audience. While the second article presents a more direct look at the implementation of the dynamic structured approach, and lessons learned through the experiential stories of the students. The dynamic structured approach is a framework which was created from a synergetic review of studies on the issues of attrition and delayed completion in graduate programs. The approach was therefore discussed in hopes that it can be used as a model in other graduate programs to ensure that students are supported in a holistic manner. Further, recommendations were made to bolster the approach based on the lessons learned from its initial implementation as well as through the reflections of the researcher-practitioner. The approach has built-in flexibility and is open to refinement and modification to suit the needs of varying institutions for future use.

Description
The problem of practice addressed in this study specifically examined how teachers lack the knowledge and experience of working with Indigenous students, thus creating a lack of connections with these students. Indigenous students have unique life experiences and world views, and the lack of knowledge and experience from teachers makes it difficult to provide adequate connections for the students in Tribal Schools. One of the driving ideas behind this research was that if non-Native teachers do not understand their students, how will they be able to connect with them and teach them effectively? Connections and relationships with teachers are one of the most beneficial factors for students. Generally, teacher preparation programs within the United States do not explicitly address the unique barriers and histories experienced by Indigenous students. The goal of this study was to assist teachers of varying cultural backgrounds in the transition from their teacher education programs to being in the classroom, teaching Indigenous students. This will better prepare future educators to teach Indigenous students in a Tribal School setting.

Description
College athletes experience college in a way that is different than their non-athlete peers. Practices, travel time, study hall, and other athletic obligations place strenuous demands on the lives and time of college athletes. As a result, college athletes have less flexible time and are often unable to engage in educationally purposeful activities including high impact practices, that promote their personal growth and development. Using Astin’s Student Involvement Theory and Rendon’s Validation Theory as frameworks, this mixed methods study examined the impact that participating in a high-impact practice activity had on the personal growth and development of college athletes. To examine how personal growth and development was impacted by participation in a high impact practice activity, National Collegiate Athletic Association (NCAA) Division I college athletes at the University of California, Riverside (UC Riverside) participated in the Leadership for Social Change seminar. To measure personal growth and development, the participants completed the Personal Growth Initiative Scale - II (PGIS-II) as a pre- and post-seminar survey. A sample of participants was also interviewed after completing the seminar to further explain the survey results. The results of the study suggest that seminar participation led to personal growth and development for college athletes. Institutions and athletic departments should promote college athletes’ personal growth and development by incorporating high impact practices into the college athlete experience.

With increasing costs of higher education, community college pathways to baccalaureate transfer degrees are attractive student alternatives to starting at a traditional four-year institution. However, disparate student outcomes, particularly for underserved student populations, continue to be a concern when considering equitable four-year degree completion rates. Previous literature demonstrates that student satisfaction and student informational capital play key roles in the success of community college transfer students to persist to four-year institutions and attain their educational and career goals. The role of academic advising in the transfer context provides a uniquely collaborative opportunity to address factors of success and student outcomes. Via this mixed methods action research study, I utilized archival student enrollment data, a student survey, and student and advisor interviews to examine an academic advising model that I created in partnership between Cochise Community College and the University of Arizona (i.e., the Colaborativo Advising for Transfer Success Model, or CATS Advising Model), whereby I assigned a singular academic advisor (i.e., a CATS advisor) a student caseload across the two institutions in a deliberate effort to facilitate successful transfer. I used a combined framework of the Model of Student Departure, Transfer Student Capital, and Appreciative Inquiry to inform the advising intervention. I found that students who received the advising intervention were significantly more likely to a) be satisfied with their transfer advising experience, b) perceive increased transfer knowledge (capital), and c) retain through transfer and university enrollment, in comparison to their peers who received advising via a more traditional transfer advising model. Importantly, the students experiencing the advising intervention were also able to articulate their appreciation and recognition of the impact of their relationship with the CATS advisors on their transfer success.

Description
The School of Entrepreneurship and Business Innovation (SEBI) student’sengagement with SEBI support services has been a matter of concern since the
establishment of the School in 2017. Of the fifteen hundred (1500) students registered at
the School, approximately 40% of them use the student support services offered to
increase retention, enhance performance, reduce uncertainties, and guide students to
success. The literature showed that student engagement is important for the greater
achievement of student outcomes, maintaining retention, as well as to offset any
ambiguity and challenges within the learning environments. The practitioner used Astin’s
Theory of Student Involvement and Tinto’s Student Integration Theory to discuss the
phenomenon of infrequent engagements of students with student support services SEBI.
The research used a mixed-method approach to investigate the current framework of
student support services at SEBI and student's engagement with these services. The
findings suggest that the students' perception of the support services offered by SEBI is
that the services are inadequate, and that their success is as a result of peer support and
their individual persistence. The practitioner proposes a student support strategy
prototype that will involve a collaboration between students and faculty members for a
more effective and efficient student support service.
