One Health: Fostering Hope For Older Adults And Homeless Companion Animals, L.F. Carver

People and Animals: The International Journal of Research and Practice

The One Health model proposes that human and nonhuman animal health be addressed in tandem, considering the well-being of both, and even including the environment. However, in practice One Health initiatives usually focus on animals as disease carriers. This paper is innovative because it extends the application of the One Health model to human and nonhuman animal well-being and mental health. One of the most challenging issues in non-human animal welfare is the management of unwanted, abandoned, and feral animals. Many of these animals will end up in a shelter or a rescue, and whether they leave alive is often …

“She’S Me”: An Exploration Of Pet Ownership From The Perspective Of People Who Are Homeless, Lana Parker, Leonie Boland, Alison Warren

People and Animals: The International Journal of Research and Practice

For many people who experience homelessness, having a pet is an important part of their lives. Although the benefit and meaning of pet ownership has been well recognized in the literature, few studies have explored its meaning from the perspectives of individuals who are homeless. This qualitative study explored the meaning of pet ownership from the perspectives of three men who previously or currently owned a pet while experiencing homelessness. In line with the chosen methodology, interpretative phenomenological analysis (IPA), semi-structured, in- depth interviews explored the phenomena of pet ownership. This paper is based on one of three themes from …

Data were collected in the form of drawings of engineers prior to and immediately after the professional development program as well as an open-ended exit survey at the end of the program. Participants’ drawings were scored in the following areas: use of mathematics, use of science, and work of an engineer. Wilcoxon signed-rank tests revealed that the only significant change between measures was in ‘‘work of …

The Importance Of Collaborative Design For Narrowing The Gender Gap In Engineering: An Analysis Of Engineering Identity Development In Elementary Students, Mandy Mclean, Jasmine M. Nation, Alexis Spina, Tyler Susko, Danielle Harlow, Julie Bianchini

Journal of Pre-College Engineering Education Research (J-PEER)

Research suggests that, to narrow the gender gap in engineering, we should focus on helping young girls identify with engineering both because gendered attitudes emerge around kindergarten and because identity is more predictive than performance on persistence in the field. This qualitative study sought to understand the impact of collaborative engineering design on the development of engineering identities in elementary-school students and compared the findings across gender. We focused on three tiers of collaboration embedded into the engineering design process: peer groups, role models, and shared goals. More specifically, the elementary students worked in small teams and partnered with undergraduate …

Implement Multi-Factor Authentication On All Federal Systems Now, Megan Walsh

Student Papers in Public Policy

The White House Office of Management and Budget recorded 31,107 information security incidents in fiscal year 2018. The most common attacks to gain access to a user’s login credentials were e-mail/phishing, web-based attack, and brute force entering of username/password combinations. Given this high number of incidents, strong reliance on computers for everyday business, and common attacks that target passwords, information security should be a priority for information technology administrators working in federal agencies.

Removing Racially Biased Algorithms In Policing, Andie Lee

Student Papers in Public Policy

Local police departments use algorithm-based programs to do police work and predict crime. Technology has created the police tactic of predictive crime prevention. Police work, however, requires social skills, assessment of the environment, and most importantly human interaction. Automated policing lacks these characteristics. Moreover, the algorithms used to make crime predictions and risk assessments have disproportionately affected minorities.

The Case For Online Ranked-Choice Voting, Rayyan Khan

Student Papers in Public Policy

Maine was the first to embrace ranked-choice voting on a statewide level in 2018, using it for all state and general elections. Maine voters will be the first to use ranked-choice voting in a presidential election in 2020. This system differs from traditional voting in that voters rank candidates rather than choose just one. Supporters of ranked-choice voting tout it as a better model for accurately representing the values of the voting population; however, a study conducted in San Francisco details a potential shortfall referred to as “ballot fatigue” that the theoretically-ideal system may face as it struggles to deal …

Analysis Of Local Seismic Events Near A Large-N Array For Moho Reflections, Qicheng Zeng, Robert L. Nowack

Geodata Science Technical Reports

Local seismic events recorded by the large-N IRIS Community Wavefield Experiment in Oklahoma are used to estimate Moho reflections near the array. For events within 50 km of the center of the array, normal moveout corrections and receiver stacking are applied to identify the PmP and SmS Moho reflections on the vertical and transverse components. Corrections for the reported focal depths are applied to a uniform event depth. To stack signals from multiple events, further static corrections of the envelopes of the Moho reflected arrivals from the individual event stacks are applied. The multiple-event stacks are then used to estimate …

Investigating Membrane Material Alternatives For Air Revitalization In Space, Gabriela Cesar, Debraliz Isaac-Aragones, David M. Warsinger, Justin Weibel

School of Mechanical Engineering Working Papers

Recently, NASA’s ultimate goal has been to launch a crewed Mars mission. However, the current system used for carbon dioxide (CO2) removal in air revitalization in the International Space Station (ISS) is not equipped to handle beyond low-earth-orbit missions. The Carbon Dioxide Removal Assembly (CDRA) is a complex system that relies heavily on sorbent materials and faces challenges in reliability, energy efficiency, and material degradation. Although the CDRA has operated well in the ISS for the past two decades, health effects from high CO2 levels are amongst the most common complaints from and challenges for astronauts.

‘Our Family Picture Is A Little Hint Of Heaven’: Race, Religion And Selective Reproduction In Us ‘Embryo Adoption’, Risa Cromer

Purdue University Libraries Open Access Publishing Fund

People use selective reproductive technologies (SRT) in various family-making practices to assist with decisions about which children should be born. The practice of ‘embryo adoption’, a form of embryo donation developed by white American evangelical Christians in the late 1990s, is a novel site for reconceptualizing SRT and examining how they function among users. Based on ethnographic research conducted between 2008 and 2018 on US ‘embryo adoption’, this study provides an anthropological analysis of media produced by and about one white evangelical couple's race-specific preferences for embryos from donors of colour. This article shows how racializing processes and religious beliefs …
