Exploring The Relationship Between Mandatory Helmet Use Regulations And Adult Cyclists’ Behavior In California Using Hybrid Machine Learning Models, Fatemeh Davoudi Kakhki, Maria Chierichetti

Mineta Transportation Institute

In California, bike fatalities increased by 8.1% from 2015 to 2016. Even though the benefits of wearing helmets in protecting cyclists against trauma in cycling crash has been determined, the use of helmets is still limited, and there is opposition against mandatory helmet use, particularly for adults. Therefore, exploring perceptions of adult cyclists regarding mandatory helmet use is a key element in understanding cyclists’ behavior, and determining the impact of mandatory helmet use on their cycling rate. The goal of this research is to identify sociodemographic characteristics and cycling behaviors that are associated with the use and non-use of bicycle …

Detecting Child Sexual Abuse Images: Traits Of Child Sexual Exploitation Hosting And Displaying Websites, Enrique Guerra, Bryce G. Westlake

Faculty Research, Scholarly, and Creative Activity

Background
Automated detection of child sexual abuse images (CSAI) often relies on image attributes, such as hash values. However, electronic service providers and others without access to hash value databases are limited in their ability to detect CSAI. Additionally, the increasing amount of CSA content being distributed means that a large percentage of images are not yet cataloged in hash value databases. Therefore, additional detection criteria need to be determined to improve identification of non-hashed CSAI.
Objective
We aim to identify patterns in the locations and folder/file naming practices of websites hosting and displaying CSAI, to use as additional detection …

Examining Perceived Effects Of Same-Sex Marriage Legalization Among Sexual Minority Women: Identifying Demographic Differences And Factors Related To Alcohol Use Disorder, Depression, And Self-Perceived Health, Laurie A. Drabble, Amy A. Mericle, Cat Munroe, Angie R. Wootton, Karen F. Trocki, Tonda L. Hughes

Faculty Research, Scholarly, and Creative Activity

Introduction

Reductions in structural stigmas, such as gaining access to legalized same-sex marriage, are associated with positive psychological and physical health outcomes among sexual minorities. However, these positive outcomes may be less robust among sexual minority women (SMW).

Methods

This study examined how perceptions of the impact of legalized same-sex marriage among SMW may (1) differ by demographic characteristics and (2) predict alcohol use disorder, depression, and self-perceived health. A diverse sample of SMW (N=446) completed an online survey in 2020 assessing the perceived impact of legalized same-sex marriage across six social-ecological domains: (1) personal impact, (2) stigma-related …

Detecting Driver Drowsiness With Multi-Sensor Data Fusion Combined With Machine Learning, Hovannes Kulhandjian

Mineta Transportation Institute

According to the National Highway Traffic Safety Administration, in 2017 drowsy driving resulted in 50,000 injuries across 91,000 police-reported accidents, as well as almost 800 deaths. Through the application of visual and radar sensors combined with machine learning, this research developed a drowsy driver detection system aimed to prevent potentially fatal accidents. The working prototype of Advanced Driver Assistance Systems can be installed in present-day vehicles to detect drowsy drivers with over 95% accuracy. It integrates two types of visual surveillance to examine the driver for signs of drowsiness. A camera is used to monitor the driver’s eyes, mouth and …

Spatio-Temporal Analysis Of The Roadside Transportation Related Air Quality (Startraq) And Neighborhood Characterization, Jaymin Kwon, Yushin Ahn, Steve Chung

Mineta Transportation Institute

To promote active transportation modes (such as bike ride and walking), and to create safer communities for easier access to transit, it is essential to provide consolidated data-driven transportation information to the public. The relevant and timely information from data facilitates the improvement of decision-making processes for the establishment of public policy and urban planning for sustainable growth, and for promoting public health in the region. For the characterization of the spatial variation of transportation-emitted air pollution in the Fresno/Clovis neighborhood in California, various species of particulate matters emitted from traffic sources were measured using real-time monitors and GPS loggers …

How Do Environmental Factors Affect Drivers’ Gaze And Head Movements?, Arash Tavakoli, Vahid Balali, Arsalan Heydarian

Mineta Transportation Institute

Studies have shown that environmental factors affect driving behaviors. For instance, weather conditions and the presence of a passenger have been shown to significantly affect the speed of the driver. As one of the important measures of driving behavior is the gaze and head movements of the driver, such metrics can be potentially used towards understanding the effects of environmental factors on the driver’s behavior in real-time. In this study, using a naturalistic study platform, videos have been collected from six participants for more than four weeks of a fully naturalistic driving scenario. The videos of both the participants’ faces …

Gaps And Opportunities In Accessibility Policy For Autonomous Vehicles, William Riggs, Anurag Pande

Mineta Transportation Institute

Nearly 1 in 5 people in the US have a disability (more than 57 million) (U.S. Census Bureau), and people with disabilities use the automobile as a travel mode at significantly lower rates than people without disabilities (Bureau of Transportation Statistics). For example, people aged 18 to 64 with disabilities make 28% fewer trips per day (2.6 v. 3.6 trips) on average than people without disabilities. The disparity is even more significant for non-workers. These statistics highlight the notable technological, design, and policy failings in today’s transportation system - that disabled individuals have considerable suppressed demand for travel that is …

In-Person To Virtual In Six Weeks: Moving A Conference Online Due To Covid-19, Emily K. Chan, Daina Dickman, Nicole Lawson

Faculty Research, Scholarly, and Creative Activity

The Scholarly Communication Assessment Forum (SCAF) was planned to be held on the Sacramento State campus on May 4 & 5, 2020. When pandemic-related shelter-in-place restrictions were imposed in mid-March and it became clear an in-person event would be impossible, the project team had to quickly shift to a virtual event. While quickly changing the format of the event was challenging, there were also unexpected benefits. The project team was able to collect much richer data by recording all sessions and breakout discussions. Extending the timeline for the project also allowed for more in depth analysis of forum transcripts and …

Ethnic Identity, Self-Esteem & Intra Group Conflicts Amongst Latinos, Christian Arevalo

McNair Research Journal SJSU

Unlike Salvadorans, Mexican/Mexican Americans have long established communities revolved around their culture. They have advanced in social class, education and political representation. On the other hand, Salvadorans have only just recently begun migrating and settling in predominantly Mexican/Mexican American communities. Competition over resources and the preservation of Mexican/Mexican American culture has caused continuing conflicts among Salvadorans and Mexicans/Mexican Americans. Additionally, inter-ethnic and in-group conflicts are also affected by generational differences (1^st, 2^nd, 3^rd generation, etc.). Due to acculturation, Latinos/as struggle to retain their cultural heritage and parents often lose the ability to influence their children’s …

Terrorism Hazard And Infrastructure Projects: The Moderating Role Of Home Experience And Institutions, Alfredo Jiménez, Nathaniel C. Lupton

Faculty Research, Scholarly, and Creative Activity

This paper analyzes the impact of terrorism hazard on the performance of private participation infrastructure projects. Applying transaction cost theory, we hypothesize that terrorism hazard has a negative relationship with infrastructure project completion, and that host government accountability and investor experience with terrorism hazard have opposing impacts on this relationship. Host government accountability, we argue, produces higher indirect costs of managing terrorism hazard, which reduces investor confidence, and reinforces the negative relationship between terrorism hazard and the probability of satisfactory project completion. Conversely, investor’s experience with terrorism hazard increases investor confidence and hence partially mitigates the negative consequences of terrorism …
