Connecting With The Outside World: Psychosocially Supportive Aspects Of Operational Communication Between Isolated Crews In Space And Mission Control On The Ground, Dennis J. Frederiksen

Journal of Human Performance in Extreme Environments

Radio-based communication between crew members in space and mission control centers on the ground has the operational purpose of supporting the safe and effective execution of missions in space. Space-to-ground communication also, however, constitutes one of the relatively few interpersonal relationships astronauts have during missions and in addition to its operational purpose, this communication can support astronauts’ wellbeing. The purpose of this paper is to identify psychosocially supportive aspects of operational space-to-ground communication between astronauts in space and spacecraft communicators on the ground. Through qualitative analysis of authentic mission communication, this paper identifies two supportive aspects and develops a terminology …

Teaching And Collecting Technical Standards: A Handbook For Librarians And Educators, Chelsea Leachman, Erin M. Rowley, Margaret Phillips, Daniela Solomon

Purdue Information Literacy Handbooks

Technical standards are a vital source of information for providing guidelines during the design, manufacture, testing, and use of whole products, materials, and components. To prepare students—especially engineering students—for the workforce, universities are increasing the use of standards within the curriculum. Employers believe it is important for recent university graduates to be familiar with standards. Despite the critical role standards play within academia and the workforce, little information is available on the development of standards information literacy, which includes the ability to understand the standardization process; identify types of standards; and locate, evaluate, and use standards effectively.

Three major themes emerged from the data: behavioral signs of safety culture at the collegiate level, obstacles to a sound safety culture, and methods to improve the safety culture. Moreover, …

Expanding On Basis Risk Estimates For Pasture, Rangeland, And Forage Insurance, Ryan Feuz, Ryan Bosworth, Ryan Larsen, Royce Larsen, Sean Klein, Matthew W.K. Shapero, Devii R. Rao, Lynnedee Althouse, Karl Striby

Journal of Applied Farm Economics

Basis risk or residual risk arising from disparity between an index’s estimate of losses and actual losses is inherent in index-based insurance products. We approximate basis risk as the false negative probability (FNP) within pasture, rangeland, and forage (PRF) rainfall index insurance for the south-central coastal region of California. We estimate the FNP on average that at least one of two selected coverage intervals will fail to provide an indemnity when a loss is realized at 48%. The average FNP is reduced to only 11% when considering whether both selected intervals fail to provide an indemnity when a loss is …

Goldilocks And The Home Mathematics Environment: Parents' Rate Activities ‘Too Easy,’ ‘Just Right,’ Or ‘Too Hard’ Across Early Development, Patrick Ehrman, Alexa Ellis, David J. Purpura

Purdue Center for Early Learning Faculty and Staff Publications

Research focusing on the home mathematics environment has shown mixed results across age groups. Using data from a large online survey, we explored parents' perceptions of the age appropriateness of home mathematics activities for their children. Children's ages ranged from one to 6 years old (N = 958). Activities spanned multiple domains of early mathematics including numeracy, geometry, patterning, spatial, and measurement domains. Descriptive statistics show there are clear developmental shifts in the appropriateness ratings for activities within and across these domains. Findings provide insight for future implications on the measurement of the home mathematics environment, as well as …

Although the 𝜀−𝑁TU method is a well-established …

Assessing The Use Of Critical Literacies In Mis/Disinformation Literacy Instruction, Melissa Chomintra

Libraries Faculty and Staff Scholarship and Research

In keeping with Freire's Pedagogy of the Oppressed and the theoretical perspicacity of Critical Race Theory, Lenoir and Anderson (2023) posit “technical solutions to political problems are bound to fail. Historical, structural, and political inequality—and especially race, ethnicity, and social difference—needs to be at the forefront of our understanding of politics and, indeed, disinformation”. The approaches to mis/disinformation in libraries and information studies have largely been grounded in two forms of literacy education; media literacy and digital literacy. Both media literacy and digital literacy offer a limited generic framing for engaging with digital information and myriad technology and fall short …

Development Of Situational Awareness Enhancing System For Av-To-Manual Handover And Other Tasks, Yujie Li, Aishwarya Sharma, Bortiorkor N.T. Alabi, Sikai Chen, Samuel Labi

Center for Connected and Automated Transportation

Partial- and conditional-automated driving systems (ADS) can not only assist drivers with their driving tasks but also significantly reduce the driving-related burden. Yet still, when the AVS is engaged, the human driver still plays a critical role such as monitoring the driving environment and performing certain driving tasks when called upon by the ADS. There exists ample evidence in the literature on simulation experiments and real-world that point to the difficulty of human drivers to maintain the requisite situational awareness to safely take over the vehicle when needed. This is often due to the nature of the non-driving related tasks …

“Dying Alone And Being Eaten”: Dog Scavenging On The Remains Of An Elderly Animal Hoarder-A Case Report, Louise Bach Kmetiuk, Paulo Cesar Maiorka, Alan M. Beck, Alexander Welker Biondo

Purdue University Libraries Open Access Publishing Fund

Animal hoarding and human consumption by dogs have been important but often understudied aspects of the human-animal bond that can be addressed within a One Health framework. No scientific report has focused on dog scavenging on animal hoarders to date, despite isolated reports of dog scavenging on human remains, mostly due to starvation. The phenomenon has been approached as a confounding factor for human forensics. In 2014, the Animal Protection Department of Curitiba City was called to rescue and handle ten small dogs which had scavenged for a week on the human remains of their elderly owner, a potential animal …

Mechanochemical Esterification Of Cellulose Nanofibers Lyophilized From Eutectic Water–Tert-Butanol Mixtures, Miran Mavlan, Taehoo Chang, Rudan Feng, Jake R. Wilkinson, Robert J. Nicholas, Nosa B. Idahagbon, Jeffrey Youngblood, Alexander Wei

Department of Chemistry Faculty Publications

Freeze-dried CNFs can be modified by mechanochemical (MC) processes with minimal use of auxiliary solvents, however aggregation of nanofibers during lyophilization compromises their granularity and reaction efficiency. Adding 10 wt% tert-butanol (TBA) to aqueous slurries of wood-derived CNF creates a eutectic mixture that reduces hornification during lyophilization, resulting in well-formed aerogels with minimal shrinkage in volume. CNFs lyophilized from mixtures containing at least 10 wt% TBA exhibit an order of magnitude increase in specific surface area relative to CNFs freeze-dried from water alone. The amount of TBA and input energy needed for lyophilization can be reduced considerably by dewatering …

On The Design And Power Output Response Of Hydraulic Wind Turbines, Helber Antonio Esquivel-Puentes, Andrea Vacca, Venkatesh Pulletikurthi, Ali Doosttalab, Jose Garcia-Bravo, David M. Warsinger, Leonardo P. Chamorro, Luciano Castillo

School of Mechanical Engineering Faculty Publications

Standard horizontal axis wind turbines typically use gearboxes for large-scale applications and direct coupling for small-scale designs to connect the rotor to the generator. However, gearboxes pose challenges due to their weight, cost, and exposure to dynamic loads and vibrations within the nacelle. A promising alternative is replacing mechanical transmission with a hydrostatic counterpart, offering advantages such as reduced nacelle mass, generator placement at the tower base, and elimination of the gearbox. It can potentially lead to cost savings of up to 20% in the levelized cost of electricity for offshore wind turbines. This study compares regulated hydrostatic transmission with …

#Hashtag Social Media Experiences: Building Positive Patron–Library Relationships, Alla Kushniryk, Stanislav Orlov

Proceedings of the IATUL Conferences

The ubiquitous presence of social media has changed the way libraries communicate with their patrons. Academic libraries usually employ social media to provide instant feedback to queries and promote library services to students and faculty. However, using these tools solely for such purposes means not fully utilizing their potential. Properly applied, social media can help build and maintain positive relationships between libraries and communities they serve. Social media experts (e.g.: Quesenberry, 2021) argue that in order to build these relationships, an organization should take a “bottom up” approach to social media by engaging with patrons through social media listening and …

The Youtube Social Capital - Library Users Finding A Place And Space On Youtube, Lindall Adams

Proceedings of the IATUL Conferences

The library is a source of social capital. Several studies have examined how library spaces, services, and programs generate social capital. In this manner, the physical library became the third space, following the first and second spaces of home and work. However, during the global lockdown, the third space closed its doors and redirected its attention to social media platforms. While libraries have been engaged in Web 2.0 endeavours since the early 2000s, maintaining social network presence has not been an option. Libraries were given the opportunity to reengage with social media as a result of the pandemic, and new …

Modeling Of A Flexible Perforated Membrane Backed By Granular Materials, Zhuang Mo, Guochenhao Song, Tongyang Shi, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

It has recently been shown that adding activated carbon particles to the interior of a Helmholtz resonator can improve the resonator’s absorption at low frequencies. A similar improvement has been found when a layer of activated carbon partially fills the space behind a finite, tensioned impermeable membrane. In that case, absorption peaks due to the modal response of the tensioned membrane were found to be significantly enhanced in the low frequency range. In the present work, the modeling aspects of the latter work are extended in a number of ways. First, the circular membrane is considered to be both tensioned …
