Aging Across Cultures: How Cultural Attitudes Shape Senior Care In Japan And The United States, Ella Jane Gunn

Honors Program Theses

The purpose of this study is to examine how cultural perceptions of aging influence the structure and delivery of care for older adults in Japan and the United States. By comparing cultural attitudes, this study identifies implications for senior care in each country. While cross-cultural studies comparing senior care systems already exist, many lack the cultural context that shapes expectations about aging and care. This work focuses on this distinction. Ten individuals ranging in age from 21 to 83 participated in interviews about their perceptions of aging: five with an American background and five with a Japanese background. The interviews …

The Role Of Parent Involvement In Enhancing Pediatric Speech And Language Therapy, Katie Lynch

Honors Program Theses

As speech-language pathologists, we provide speech and language therapy for children in a variety of settings. It is crucial that we include a client’s family in therapy because family involvement has been shown to promote generalization of skills learned in therapy to a child’s typical environment. Despite this, various barriers exist for families as they aim to support their child’s speech and language goals. This literature review examines how speech-language pathologists can gain an understanding of these barriers and how they can promote family involvement in pediatric speech and language therapy.

Exploring The Relationship Between Bmi Classification And Levels Of Food Noise, Edmarie Billosillo

Loma Linda University Research Reports

Rising rates of obesity in the United States necessitates an understanding of the multitude of factors that contribute to it. Recently, “food noise” has emerged as a topic of interest in this space. The current survey-based observational study aimed to understand the relationship between Body Mass Index (BMI) and levels of food noise. The results indicate a significant association between BMI and food noise levels and a connection between a history of disordered eating and food noise levels. Additionally scores on the Food Noise Questionnaire (FNQ) and the Food Cravings Questionnaire - Trait – reduced (FCQ-R-r) were found to be …

Comparing Perceived Ideal Protein Intake In Plant-Based Versus Meat-Based Diet Consumers, Gysel Avendano, Saya Iwanaga

Loma Linda University Research Reports

High-protein diets have gained significant popularity in both social media and public discussion and more recently, a significant rise in protein consumption has been observed. Existing research has reported differences in actual protein intake across dietary patterns, with animal-based diets generally associated with higher total protein intake compared to plant-based diets. This growing focus on protein raises important questions about perceived ideal protein intake and the factors that shape it.

The primary objective is to compare perceived ideal protein intake among Southern California adults consuming meat-based versus plant-based diets. Additionally, we explored the influence of protein-related knowledge, beliefs, values, information …

The Emerging Social Media Water Cooler? Motivations For Reddit Use In A Niche League, Jan Boehmer, Brendan O'Hallarn

Communication & Theatre Arts Faculty Publications

Social media play a key role in sport marketing—with athletes, teams, and leagues directly engaging with their audiences. While Facebook, Instagram, and Twitter have received much attention in the sport marketing and communication literature, research on Reddit is scant. This is particularly noteworthy, as the platform is growing rapidly and promises utility for users with nonmainstream interests to find and engage with each other. This study employs a uses and gratifications approach to investigate how prevalent Reddit use is among fans of the United Football League (UFL), what motivates users to engage with the platform, and whether Reddit use leads …

Stages Of Being Foreign As Portrayed In Daughter Of Keltoum And Lost Birds, Fran Hassencahl

Communication & Theatre Arts Faculty Publications

In this paper, I use the intercultural communication model, The Stages of Being Foreign, developed by anthropologist Oberg (1960) and modified by Gullahorn & Gullahorn (1963), Lewis & Jungman (1986), and Ward, Bochner, and Furnham (2001) to explain the experience of culture shock. This model describes the stages that individuals experience when they leave, either voluntarily or involuntarily, their home country/culture and must adapt to a new culture. These stages as described by Oberg are a preliminary stage (a spectator stage), an increasing participation stage, the pit of the culture shock stage, the adaptation stage, and for some migrants a …

Crypto Exchanges In Market Regulation, Yesha Yadav

Vanderbilt Law Review

The cryptocurrency market has proven notoriously challenging to regulate despite a decade during which it has gained in economic size, sophistication, and cultural impact. Even as repeated crises have left ordinary savers wiped out, regulation has shown itself to be woefully absent as a means of mitigating risks ex ante or helping cover the cost of damage ex post. This Article looks to break this deadlock by proposing a tried-and-tested solution: It argues that regulators should task crypto exchanges with providing oversight as self-regulatory organizations of the crypto market in which they play an anchoring role. It offers three supporting …

Presidential Immunity: Before And After Trump, Thomas P. Schmidt

Vanderbilt Law Review

'All the officers of government," the Supreme Court said long ago, "from the highest to the lowest, are creatures of the law, and are bound to obey it." Despite that ringing and categorical language, however, the Court has held that the President-the "highest" and most powerful of all government officers-is "immune" from judicial oversight in several respects. Indeed, when the Court held last Term that former presidents are presumptively immune from criminal prosecution for officials acts, the dissenters warned: '`n every use of official power, the President is now a king above the law."

This Article unpacks the various presidential …

A Phenomenological Analysis Of Sense Of Belonging Among Community College Educators, Muhammad Owais Aziz

EVMS School of Health Professions Theses & Dissertations

This phenomenological study explored the complex phenomenon of sense of belonging (SB) among diverse health professions educators (HPEs) and non-health professions educators (non-HPEs) at a Canadian community college. SB, as a dynamic construct shaped by an individual's perception of being valued and respected, is influenced by personal preferences and by complex interactions with the individual's surroundings. To better understand SB and foster a more inclusive environment for diverse educators, it is necessary to investigate SB among these educators. This qualitative study used eleven semi-structured interviews and seven steps of data analysis. The results of this study can inform strategies, policies, …

Migration Of Copper Bullet Fragment Through The Orbit And Conjunctiva, Maxwell A. Levi, Mehron G. Kouhestani, Giovanni Disandro, Peter A. Netland

Department of Ophthalmology Faculty Publications

This is a case report of a 31-year-old female who sustained a gunshot wound to the left orbit, resulting in a ruptured globe and retained bullet fragments extending into the frontal lobe. The patient underwent enucleation without orbital implant, and no metallic fragments were recovered intraoperatively. Three months later, she returned with bloody conjunctival discharge. Examination revealed a 1.25-cm copper-colored metallic bullet jacket fragment spontaneously protruding through the conjunctiva. Serial CT imaging confirmed anterior and inferior migration of the bullet fragment over time, with a total migration distance of 32.9 mm through the orbit. The shrapnel was removed in clinic …

Outcomes Of Allogeneic Ocular Surface Stem Cell Transplantation, Albert Y. Cheung, Natalia Quiroz-Casian, Enrica Sarnicola, Gautam C. Ramanathan, Siddharth Nath, Edward J. Holland

Department of Ophthalmology Faculty Publications

Allogeneic ocular surface stem cell transplantation (OSST) is an established therapeutic approach for limbal stem cell deficiency, utilizing techniques such as keratolimbal allograft (KLAL), living-related conjunctival limbal allograft (lr-CLAL), allogeneic cultivated limbal epithelial transplantation (allo-CLET), and allogeneic simple limbal epithelial transplantation (allo-SLET). This review synthesizes evidence from 35 studies encompassing 1, 268 eyes with at least 24 months of follow-up to evaluate intermediate- and long-term outcomes. Overall, OSST is associated with improvement in visual acuity and restoration of ocular surface stability, although success rates vary widely by technique, ranging from 13% to 87%. Outcomes appear to be influenced by the …

Ocular Surface Disease Following Lasik And Cataract Surgery: A Review Of Their Interrelated Complications, Matthew D. Spangler, Nila Kirupaharan, John D. Sheppard

Department of Ophthalmology Faculty Publications

Background: Ocular surface disease is a multifactorial condition that is very commonly caused by dry eye disease (DED). Ophthalmic procedures intended to improve visual outcomes, laser-assisted in situ keratomileusis (LASIK) and cataract surgery, can paradoxically cause or exacerbate underlying ocular surface disease. This results in worsening vision and quality of life.

Areas covered: This review examines the pathophysiological mechanisms contributing to ocular surface disease development following LASIK and cataract surgery. Both procedures are associated with the transection of corneal nerves, leading to decreased tear production, surface instability, altered neurotrophin production, and impairment of the blink reflex. Furthermore, these incisional procedures …
