Computed Tomography In Medicolegal Death Investigation: A Critical Review, Trenton Eames

University Honors Theses

The use of computed tomography (CT) scanning in medicolegal death investigations has increased in frequency in recent years. It can be used by investigators to help identify a victim, find a cause of death, or otherwise reveal legally relevant case details. This meta-analysis aimed to examine the research surrounding the use of CT scanning in medicolegal death investigation, focusing in particular on researchers’ scrutiny of the accuracy and precision of this technique within forensic contexts. Thirty-nine research papers were reviewed, with specific attributes and findings examined together in an effort to contextualize CT scanning in medicolegal death investigations. CT scanning …

A Data Collection Program For Reducing Ipv In Lgbtq+ Communities, Alexandra Michel, Nicholas Cheke, Lourdes Gonzalez, Rachel Greim

OHSU-PSU School of Public Health Annual Conference

Sexual and gender minority populations are not currently being accurately tracked or counted in most domestic violence (DV) and intimate partner violence (IPV) surveillance programs in Oregon. However, research indicates that LGBTQ+ populations experience IPV at rates comparable or even higher than heterosexual populations. Additionally, distrust of law enforcement and services designed around heterosexual experiences of IPV further reduce the ability of LGBTQ+ populations, particularly transgender women, to access IPV services. We propose that through the use of a PRECEED-PROCEED model, a program could be developed to more accurately collect sexual orientation and gender identity data by IPV service providers …

Incidence Of An Astronaut Not Closing The Pressure Garment Visor On Reentry, Cameron M. Smith

Anthropology Faculty Publications and Presentations

Audiovisual records of a Project Mercury pilot's activities during an orbital flight indicate that his visor was left open during reentry and descent to the sea surface, phases of flight during which cabin pressure loss was to be mitigated by suit pressurization; however the suit could not have been pressurized with the visor open. Thus, for a presently unknown reason, a critical safety step—sealing the visor and making a pressure suit integrity test before re-entry—was overlooked in this flight, a fact itself unreported in any flight review or historical documents known to the author. The lesson is clear: even a …

Lambda Alpha Anthropology Honors Society (Lab): Bridging The Gap Between Coursework And Career, Adriana Stein, Stefanie Berganini

Student Research Symposium

Many anthropology majors gain an academic familiarity with the subject through coursework, but lack an understanding of how to utilize their anthropological skills outside of academia in future careers. To remedy this issue, the Lambda Alpha Beta Honor Society (LAB), a student-led anthropology organization at Portland State University, provides opportunities for participation in events that get students involved with our local community, such as non-profit organizations and local cultural institutions. Some of these organizations include the Oregon Museum of Science and Industry (OMSI), Clark Public Utilities, The Ridgefield Wildlife Refuge, Potluck in the Park, and Habitat for Humanity. As an …

Pressure Test Results Regarding Convolute Elbow Segments And Biomedical Monitoring, Cameron M. Smith

Anthropology Faculty Publications and Presentations

Pacific Spaceflight’s Mark II / III pressure garment (model Gagarin with one newly-built elbow segment on the left arm) was pressurized to evaluate the mobility allowed by the newly-installed convolute arm compared to the right arm’s older convolute elbow segment. Additionally a new helmet hold-down cable system was tested, as well as the C02 scrubbing system and heart rate, Sp02, suit’s exhausted gas C02 levels and a new communication system. At pressures of 2.3psi – 2.5psi the helmet hold-down cable came free of the new hardware (a sailboat’s one-way cleat system), raising the helmet ring explosively. This resulted from the …

Flight Test Of Pacific Spaceflight Pressure Garment Mark Ii In Bell 206 Jet Ranger, Cameron M. Smith

Anthropology Faculty Publications and Presentations

Pacific Spaceflight’s Mark II pressure garment (model Gagarin) was test flown to 17,200 feet MSL (5,242m) while worn and operated by Dr. C.M. Smith. The garment and its portable life support system (PLSS) maintained appropriate pressure, temperature and carbon dioxide levels throughout the 47-minute flight. The suit also provided sufficient elbow mobility, due to its convolute joints, for the suited person to operate the portable life support system’s manual suit pressure setting valve and the hand-held radio.

Hypobaric Chamber Test Of Pacific Spaceflight Pressure Garment Mark I At Copenhagen University Hospital, Cameron M. Smith

Anthropology Faculty Publications and Presentations

Pacific Spaceflight's first proof-of concept pressure garment, the Mark I (model Gagarin), was worn by a test subject in a pressure chamber to test stable maintenance of blood oxygenation, body temperature and suit pressure. While breathing normal air at a simulated altitude of 4,000m (c.13,000ft) the test subject's blood oxygenation was 90%, a figure expected for an altitude of 2,590m (8,500ft). The test subject's blood oxygenation climbed back to normal (96%-95%) as the hypobaric chamber was repressurized to sea level figures. The garment successfully maintained the test subject in the first half of the Blood Oxygenation Disassociation Range of …

Review Of High Altitude Aviation Preoxygenation / Denitrogenization Procedures And Draft Pressure Schedule For Open-Cockpit Balloon Flight To 65,000 Feet, Cameron M. Smith

Anthropology Faculty Publications and Presentations

Aviation Decompression Sickness (DCS) is a well-known and well documented phenomenon in which a spectrum of physiological and cognitive symptoms result from aircrew exposures to altitudes greater than roughly 10,000 feet, where atmospheric pressures and the partial pressure of oxygen are significantly lower than the mean pressures in which the human body has evolved. The main factors involved in the likelihood of DCS are (a) exposure altitude, (b) exposure time at altitude, (c) preoxygenation / denitrogenization duration and procedure and (d) exercise at the exposure altitude. Mitigation of DCS is largely achieved by (a) preoxygenation / denitrogenization before flight, (b) …

Community-Based Approaches To Mental Health And Conflict Resolution In Post-Conflict Libya, Amanda Lubit

Anthropology Theses

Post-conflict Libya faces the challenges of establishing a national health system that is capable of addressing mental health needs for a population traumatized by decades of repression and a recent war. In order to recover, traumatized populations require feelings of safety, calm, empowerment, connectedness, and hope. To help achieve this outcome, programs must focus on medical and social aspects at both the individual and community level.

As part of an internship experience, I worked with Dr. Omar Reda, a Libyan psychiatrist at Oregon Health and Science University (OHSU) who helps communities, organizations and mental health professionals throughout Libya to address …

The Women's Liberation Movement And Identity Change : An Urban Pilot Study, Molly M. Doeneka

Dissertations and Theses

The purpose of this study was to determine if participation in Women's Liberation results in identity change in the individual participants. As a pilot study, it examines the characteristic experiences of a study group of twenty-six local participants and compares the effects of their participation with a theoretical model of identity change process proposed by Ward H. Goodenough in Cooperation in Change. According to this model the process of identity change is a consequence of specific kinds of realizations fostered by a series of definable stages which are: 1) achieving a desire for identity change, 2) making a commitment to …
