Case Study: Current Suicide Prevention Initiatives in Construction
Cory Hampton.
Suicide prevention and mental health awareness and prevention are not new to the construction industry. In 1958 Los Angeles, California had the first suicide prevention center and in 1966 the National Institute of Mental Health established the Center for Studies of Suicide Prevention (National Library of Medicine, 2012). Subject matter experts such as Cal Beyer and Dr. Sally Spencer Thomas have been paving the way for this conversation since the 1990s. Their work, as well as the work of others, has been…

Modeling the Conditional Variance of Returns on Agricultural Commodity Futures Contracts
dr Gabriela Malik.
In this paper various GARCH family models are examined to find the one best suited for modeling the conditional volatility of returns of soft commodity futures. The data came from the Chicago Mercantile Exchange (CME) and covered the period from 1987 to 2022. Three different commodities were selected, namely corn, soybeans and wheat. The most striking finding of this study is that there is not much difference between the models of conditional volatility for a given commodity and across the commodities under…

Survey: Current Climate in the Construction Industry – Suicide Prevention and Mental Health Awareness
Cory Hampton.
The construction industry has one of the highest rates of suicide compared to other industries. To provide a solution to this and reduce these numbers, it is important to determine what employers are currently doing to address suicide in the workplace and how these efforts are received by employees. Finding the root cause(s) and implementing proactive solutions to suicide in the construction industry is the goal. Before this can be achieved, an industry assessment is necessary. This article evaluates the…

Integrating Alternative Ultrasound Technology into Saturation Facility Operations
Scott Van Hoy.
It is widely accepted that the presence of venous gas emboli (VGE) is a necessary but insufficient condition for the development of decompression sickness (DCS) and that variability in physiological factors may contribute to DCS. With multiple organizations designing undersea saturation facilities that may see a substantial number of divers saturating, this creates an opportunity for the divers to volunteer as research participants to study the physiological factors influencing the inter-variability of VGE and…

Technical paper: The Wideband Challenge for RF Filters and SWAP-C
Matthew Torpey, Dr. Michael E. Johnson MRAeS.
There is a continuously evolving, unmet need for RF (Radio Frequency) Filters that operate contiguously over multiple frequency octaves or bands. Unlike traditional switched filter banks, these new filters require similar levels of RF performance but with more filters and a smaller overall footprint. Legacy systems typically operate over a sub-octave and filters meant to break down information from the aperture to sub-bands (octave wide) or a little less. These wideband filters, pre-LNA (low noise amplifier),…

Space Habitat Human Factors Testing Using Simulated Space Missions
Scott Van Hoy, Dr. Michael Johnson.
Usability, acceptability, and habitability questionnaires have previously been developed and implemented by the National Aeronautics and Space Administration (NASA) to collect human factors engineering feedback about both operational and prototype space habitats. During a twelve-day simulated space mission at the Integrated Lunar/Mars Analog Habitat at the University of North Dakota, three crew members submitted habitability feedback using an adapted NASA questionnaire to measure the types, novelty, and…

Home Fire Sprinklers: Economic Incentives and Emerging Technologies
Ryan Silvia.
The debate regarding the cost/benefit of home fire sprinklers remains a significant point of contention between supporters and opponents of the proliferation of this technology. Home fire sprinklers are opposed by many homebuilders’ groups, who see them as too costly for too little benefit and believe that they do not meet the required standards of affordability. With previous research indicating that the cost of sprinkler installation is the chief concern among potential homebuyers, it is reasonable that…

Estimation of Parameters of Marginal Distributions of Return Rates of Selected Agricultural Products Listed on the Chicago Commodity Exchange
Dr. Gabriela Malik.
The article aims to estimate and verify the correctness of the specification of tail distributions of return rates of agricultural products listed on the Chicago Commodity Exchange from 1987 to 2022. The selected products include corn, soybeans, and wheat. The analysis determined a model describing the examined series concerning mean and variance values, considering the relationships between the series. To describe the tail distributions, a GARCH model was utilized. In the subsequent stage, the quality of fit…

Case Study: Introducing Suicide Prevention and Mental Health in the Workplace
Cory Hampton, Marissa Gallegos.
Fifteen construction workers die by suicide every day nationwide. This statistic alone made it evident to the researchers’ organization that they could not take a passive role in reducing and preventing suicide in the workplace. The struggle was how to do this. There are organizations that researchers were able to learn from and receive guidance from, but it was found that there was no one size fits all program. Each organization is unique, and their needs reflect this. This research maps out how researchers…

Defining Digital Boundaries: A Study on Israel’s Cyber Sovereignty Policy
Tal Pavel.
Objectives – The research aims to shed light on Israel's official policy towards defining its cyber sovereignty and boundaries based on official Israeli documents published by the Government of Israel, the Israel National Cyber Directorate and the Israel Defense Forces. Prior Work – The terms "Cyber" and "Sovereignty" define two different domains, the artificial and the physical, which may have broad definitions. Therefore, the literature defines "Cyber Sovereignty" differently while reflecting the term's…

Understanding How System-on-a-Chip Data Can Leak over Radio Transmissions
Tom Gallagher.
The 2018 Screaming Channels research raised cybersecurity concerns about mixed-signal electronic devices. Fully appreciating those concerns requires background in electrical engineering, cybersecurity, and cryptography. This article provides the necessary foundation and presents the Screaming Channels phenomenon in a way that is understandable for the masses. Electronic devices are becoming smaller and denser, introducing risk that electronic noise from sensitive processing will leak into broadcasts from the…

Homebuyer Opinions on Home Fire Sprinklers
Ryan Silvia.
This research article aims to gather data regarding home buyer attitudes toward home fire sprinkler systems. Specifically, the research article will seek to determine the price threshold where home buyers would be willing to invest in a home fire sprinkler system. To that extent, a survey instrument was developed to understand public opinion on home fire sprinklers, including any demographic differences such as age, gender, and income, as well as preexisting knowledge of home fire sprinkler technology as…
