Biopsychosocial Risk Factors And Knowledge Of Cervical Cancer Among Young Women: A Case Study From Kenya To Inform Hpv Prevention In Sub-Saharan Africa, Irene Ngune, Fatch Kalembo, Barbara Loessl, Lucy W. Kivuti-Bitok

Research outputs 2014 to 2021

Background Cervical cancer is the second most common female reproductive cancer after breast cancer with 84% of the cases in developing countries. A high uptake of human papilloma virus (HPV) vaccination and screening, and early diagnosis leads to a reduction of incidence and mortality rates. Yet uptake of screening is low in Sub-Saharan Africa and there is an increasing number of women presenting for treatment with advanced disease. Nine women in their twenties die from cervical cancer in Kenya every day. This paper presents the biopsychosocial risk factors that impact on cervical cancer knowledge among Kenyan women aged 15 to …

Land Of The Falling "Poison Pill" Understanding Defensive Measures In Japan On Their Own Terms, Alan K. Koh, Masafumi Nakahigashi, Dan W. Puchniak

Research Collection Yong Pung How School Of Law

Embraced by United States ("U.S.") managers in the 1980s as a lifeline in a sea of hostile takeovers, the poison pill fundamentally altered the trajectory of American corporate governance. When a hostile takeover wave seemed imminent in Japan in the mid-2000s, Japanese boards appeared to embrace this American invention with equal enthusiasm. Japan's experience should have been a ringing endorsement for the utility of American corporate governance solutions in foreign jurisdictions -but it was not to be. Japan's unique interpretation of the "poison pill" that was so eagerly adopted by Japanese companies in the mid-to-late 2000s has turned out to …

Stable Dispersion Of Coal Fines During Hydraulic Fracturing Flowback In Coal Seam Gas Reservoirs - An Experimental Study, Faisal Ur Rahman Awan, Alireza Keshavarz, Hamed Akhondzadeh, Sarmad Al-Anssari, Ahmed Al-Yaseri, Ataollah Nosrati, Muhammad Ali, Sefan Iglauer

Research outputs 2014 to 2021

In subterranean coal seam gas (CSG) reservoirs, massive amounts of small-sized coal fines are released during the production and development stages, especially during hydraulic fracturing stimulation. These coal fines inevitably cause mechanical pump failure and permeability damage due to aggregation and subsequent pore-throat blockage. This aggregation behavior is thus of key importance in CSG production and needs to be minimized. Consequently, such coal fines dispersions need to be stabilized, which can be achieved by the formulation of improved fracturing fluids. Here, we thus systematically investigated the effectiveness of two additives (ethanol, 0.5 wt % and SDBS, 0.001 and 0.01 wt …

Non-Song Vocalizations Of Humpback Whales In Western Australia, Angela Recalde-Salas, Christine Erbe, Chandra Salgado Kent, Miles Parsons

Research outputs 2014 to 2021

This study presents non-song vocalizations of humpback whales (Megaptera novaeangliae) from two migratory areas off the Western Australian coast: Geographe Bay and Port Hedland. A total of 220 sounds were identified as non-song sounds in 193 h of recordings reviewed. Of those, 68 were measured and qualitatively classified into 17 groups using their spectral features. One group (HW-02) had a high level of variation in terms of spectral slope. However, further classification using statistical classification methods was not possible because of the small sample size. Non-song sound frequencies varied from 9 Hz to 6 kHz, with the majority of sounds …

Faculty Research, Scholarly, and Creative Activity

Civility between health professions students and fieldwork educators enhances positive learning outcomes, while incivility can lead to stress, loss of confidence, mistakes, disengagement, and decreased patient outcomes. A survey of recent graduates of occupational therapy programs (N = 247) explored the prevalence and types of incivility and bullying experienced during their Level II fieldwork experiences. Respondents reported that incivility in fieldwork education was widespread, with more severe experiences of bullying reported by 16% of respondents. Occupational therapy programs and fieldwork educators must take an active role in prevention and management of uncivil behaviors, and promote positive academic and patient care …

A Sense Of Brutality: Philosophy After Narco-Culture, Carlos Alberto Sánchez

Faculty Research, Scholarly, and Creative Activity

Contemporary popular culture is riddled with references to Mexican drug cartels, narcos, and drug trafficking. In the United States, documentary filmmakers, journalists, academics, and politicians have taken note of the increasing threats to our security coming from a subculture that appears to feed on murder and brutality while being fed by a romanticism about power and capital. Carlos Alberto Sánchez uses Mexican narco-culture as a point of departure for thinking about the nature and limits of violence, culture, and personhood. A Sense of Brutality argues that violent cultural modalities, of which narco-culture is but one, call into question our understanding …

Processing And Characterization Of Ceria-Zirconia Containing Graphene Quantum Dots, Andrew Dina

Master's Theses

Zirconia-based nanoparticles have been used in various applications, such as catalyst, filters, oxygen storage, and sensors. Among many synthesis methods to produce zirconia (ZrO2) nanoparticles, aqueous sodium borohydride (NaBH4) precipitation has shown to be simple and capable of large-scale production. In this work, the NaBH4 precipitation of ZrO2 was extended to include ceria (CeO2) and graphene quantum dots (GQDs). The resulting nanocomposites were characterized by thermal, crystallographic, compositional, and electron microscopy analysis techniques. The presence of CeO2 lowered the amorphous to tetragonal phase transformation temperature by ~40 ℃. The presence of GQDs did not affect the amorphous to tetragonal transformation …

Nexgen D-Tcp: Next Generation Dynamic Tcp Congestion Control Algorithm, Madhan Raj Kanagarathinam, Sukhdeep Singh, Irlanki Sandeep, Hanseok Kim, Mukesh Kumar Maheshwari, Jaehyun Hwang, Abhishek Roy, Navrati Saxena

Faculty Research, Scholarly, and Creative Activity

With the advancement of wireless access networks and mmWave New Radio (NR), new applications emerged, which requires a high data rate. The random packet loss due to mobility and channel conditions in a wireless network is not negligible, which degrades the significant performance of the Transmission Control Protocol (TCP). The TCP has been extensively deployed for congestion control in the communication network during the last two decades. Different variants are proposed to improve the performance of TCP in various scenarios, specifically in lossy and high bandwidth-delay product (high- BDP) networks. Implementing a new TCP congestion control algorithm whose performance is …

Determination Of Demagnetizing Factors Using First-Order Reversal Curves And Ferromagnetic Resonance, K. S. Muster, R. Heindl

Faculty Research, Scholarly, and Creative Activity

We present a method to quantitatively analyze magnetizing or demagnetizing interactions in arrayed nano-magnets by combining first-order reversal curve (FORC) and ferromagnetic resonance (FMR) measurement data. We develop a function to predict the resulting FORC distribution given: (1) a Gaussian intrinsic distribution in terms of the internal field and (2) a mean interaction field proportional to the sample's magnetic moment. We then perform least-squares regression of our model on experimental FORC measurements of a nanowire array and of a thin film. Combining the obtained interaction field with an FMR fit result allows us to algebraically solve for the effective axial …

Innovation Institutions And The Opioid Crisis, Daniel J. Hemel, Lisa Larrimore Ouellette

Coase-Sandor Institute for Law & Economics Research Paper Series

The United States has recently—and belatedly—come to recognize opioid addiction as a public health crisis. What has gone mostly unrecognized is the degree to which this crisis is intertwined with U.S. intellectual property law and related elements of U.S. innovation policy. Innovation institutions—the legal arrangements that structure incentives for production and allocation of knowledge goods—encouraged the development and commercialization of addictive painkillers, restricted access to opioid antidotes, and (perhaps most importantly) failed to facilitate investments in alternative, non-addictive treatments for chronic pain. Although innovation policy does not bear all the blame for the opioid wave that has washed over communities …

Racial Purges, Robert L. Tsai

Faculty Scholarship

In a two-year period, 1885-86, over 168 communities in America forcibly expelled Chinese residents from their midst. This essay, inspired by historian Beth Lew-Williams's book, THE CHINESE MUST GO, investigates the nineteenth-century purges of Chinese residents that occurred throughout the American west. I make three arguments. First, these acts of racial and political terror complicate our understanding of racial violence in America. Many of the actions were denounced, but they were also surprisingly effective in forcing business and political leaders to support the indefinite suspension of Chinese migration. Perpetrators faced almost no legal repercussions, and unlike for freed persons, racial …

HIV-related stigma among people living with HIV (PLHIV) is associated with worse health outcomes. We used longitudinal data from a multisite cohort in South Africa to assess changes over time in stigma after HIV diagnosis and determine whether antiretroviral therapy (ART) initiation is associated with stigma reduction. We administered the Internalized AIDS-Related Stigma Scale (IARSS, a six-item dichotomous scale questionnaire) at baseline, 3 months, and 6 months to newly diagnosed ART-eligible participants between 2014 and 2015. A confirmatory factor analysis indicated that the IARSS contained a four-item internalized stigma factor (α = .80) and a two-item disclosure concerns factor (α …

Analysis Of Covid-19 Transmission: Low Risk Of Presymptomatic Spread?, Mark K. Slifka, William B. Messer, Ian J. Amanna

OHSU-PSU School of Public Health Faculty Publications and Presentations

More than 6 million confirmed cases of COVID-19 (coronavirus disease 2019) have been identified worldwide and a number of case reports1-5 have indicated that COVID-19 has the potential to be transmitted prior to disease onset. Studies have also shown that infectious virus can be isolated from presymptomatic COVID-19 cases6 and although it is unknown what level of infectious virus is needed to confer efficient transmission potential, detection of infectious virus in the upper respiratory tract indicates that presymptomatic transmission of COVID-19 is plausible. Fear of asymptomatic and presymptomatic transmission of COVID-19 has led to considerable concern among public health policy …

Covid-19 And Individuals With Developmental Disabilities: Tragic Realities And Cautious Hope, Samuel J. Levine

Scholarly Works

The COVID-19 pandemic has cast the United States, along with the rest of the world, into a time of crisis and uncertainty unlike any other in recent memory. Months into the pandemic, there is scant agreement among scientists, government officials, and large segments of the public, both domestic and abroad, as to determining the causes and workings of the virus, designing appropriate and effective responses to the outbreak, and constructing accurate assessments of the future—or even of the present. Indeed, the availability of concrete information about the virus and its effects is grossly inadequate and often replaced by anecdotal or …

Faculty Research, Scholarly, and Creative Activity

The world of digital materials presents archivists with many opportunities to access, present, and engage with materials in more flexible ways. Of course, this also presents challenges, including feeling like we do not know the “right” way to proceed, or knowing that we lack the resources to proceed the way we believe is best. In The Theory and Craft of Digital Preservation, Trevor Owens offers a set of frameworks and concepts related to digital preservation with the expectation that an understanding of a few basic principles will provide an informational foundation, allowing archivists to respond with professional expertise and creativity …

Unstructured Data For Cybersecurity And Internal Control, Jesus Canelón, Esperanza Huerta, Normal Leal, Terry Ryan

Faculty Research, Scholarly, and Creative Activity

This paper proposes a research framework for studying the connections-realized and potential-between unstructured data (UD) and cybersecurity and internal controls. In the framework, cybersecurity and internal control goals determine the tasks to be conducted. The task influences the types of UD to be accessed and the types of analysis to be done, which in turn influences the outcomes that can be achieved. Patterns in UD are relevant for cybersecurity and internal control, but UD poses unique challenges for its analysis and management. This paper discusses some of these challenges including veracity, structuralizing, bias, and explainability.

A Public Health Law Path For Second Amendment Jurisprudence, Michael Ulrich

Faculty Scholarship

The two landmark gun rights cases, District of Columbia v. Heller and McDonald v. City of Chicago, came down in 2008 and 2010, respectively. In the decade that has followed, two things have become abundantly clear. First, these cases provide little clarity about the nature and scope of Second Amendment rights, resulting in chaos and circuit splits in the lower courts. Second, growing empirical evidence has revealed that, in the background of the debate on individual constitutional rights, a serious gun violence epidemic is intensifying around the country. In one corner, gun rights advocates worry that increased firearm regulation will …
