An Analysis of Alcohol, Mental Health, and Suicide
Get PDFSuicide rates in Montana, Iowa, Ohio, and New Jersey vary strongly and encompass the wide range seen across all fifty states in America. Previous research has told us that there is a significant relationship between Alcohol Use Disorder and the ideation, attempt, and completion of suicide. Additionally, most people who are victims of suicide suffer from mental disorders. People use alcohol to cope with mental health and alcohol leads to deteriorating and adverse outcomes in a person’s life. To attempt to better understand the relationship between these variables and why suicide rates differ so widely, an analysis of binge drinking, mentally unhealthy days, and suicide was performed using data from the counties in these states using data from County Health Rankings in 2016 and 2023. We performed a paired t-test to determine that the number of mentally unhealthy days significantly increased in Montana counties from 2016 (3.366) to 2023 (4.425) (t = -32.671, p \u3c .001). Using an ANOVA, binge drinking rates by counties between Montana, Iowa, Ohio, and New Jersey in 2023 were seen to significantly differ (F3,260 = 294.271, p \u3c .001). Montana and Iowa had a significantly higher rate of binge drinking (24.48%, 23.95%) than the other states tested, and Ohio and New Jersey had a significantly lower rate of binge drinking (19.00%, 20.15%) than the other states tested. Using an ANOVA once more, suicide rates by counties between Montana, Iowa, Ohio, and New Jersey in 2023 were seen to be significantly different (F3,198 = 88.755, p \u3c .001). Montana had a significantly higher rate of suicide (31.26) than the other states tested, and New Jersey had a significantly lower rate of suicide (8.58) than the other states tested. Through a Pearson correlation, we found that in Ohio in 2023, as the average number of mentally unhealthy days changed, the percentage of excessive drinking weakly and negatively correlated (r = -.346, p \u3c .001). Through an unpaired t-test, the percentage of mentally unhealthy days between Montana (4.43%) and New Jersey (4.46%) counties in 2023 was not seen to be significantly different (t = -.428 p = .670) but the percentage of suicides between Montana (31.26%) and New Jersey (8.85%) counties in 2023 were seen to be significantly different (t = 10.775 p = \u3c .001)

Facilitating Passenger Acceptance of eVTOL: Management of Expectation and Experience
Get PDFFor passengers accustomed to commercial fixed-wing flight, electric vertical takeoffand landing aircraft (eVTOLs) will represent a novel form of air travel. Thepassenger experience of urban air mobility (UAM) eVTOLs will encompass newsounds, vibrations, motions, and a visual field flooded with close-up views of theurban canyon. Research on passenger acceptance has largely relied on text-basedquestionnaires. However, acceptance will be influenced by how experiencecompares to expectations and the extent to which discomfort or, in the worst case,distress, is experienced. The existing passenger discomfort literature focuseslargely on the impact of noise and vibration. Compared with traditionalcommercial flight, passengers may experience greater range, intensity, andvariability of noise and vibration. Their experience may include turbulence withinurban airflows. Expectations may be influenced by sleek, futuristic designs and bythe initial executive-transportation use case. There is, therefore, a potential for amismatch between passengers’ expectations and their experience. Novel aspectsof eVTOL flight may provoke fear in passengers with no prior fear-of-flyinghistory. Potential triggers include flight operations amongst tall buildings, ahigher incidence of turbulence, unfamiliar motions, and distrust associated withnovel technology. Remote or autonomous flight, lacking the reassuring presenceof onboard human crew, may exacerbate these concerns. This paper exploresnovel aspects of eVTOLs that may cause discordance between expectation andreality, as well as discomfort and distress. By considering how these challengescould be overcome through existing knowledge, this paper aims to help facilitatepassenger acceptance of these exciting new aircraft
Organizational Safety From the Work Floor Perspective
Get PDFLooking at organizational safety from the work floor perspective, with an operational mindset, may identify different causes for deficiencies in organizational safety that may not easily be addressed by authorities. Even though accident rates in aviation continue to slowly decline (ICAO safety reports), certain practices can be observed from a work floor perspective that might reverse this trend. Management style in a company may suppresssafety related signals from the work floor. Formal feedback processes may not be effective for all safety related issues. To clarify the threat, we present a model that identifies three components of safety. From case studies also barriers to safety innovations are identified, that are embedded in the procedural and legal oriented mindset of present day management and authorities.With the increased complexity of present day airborne equipment the question emerges ifthe certified status of systems and procedures must remain static or does require some maintenance by authorities.This conference paper will include a, work floor based, analysis of safety related mechanisms in present day aviation operation and will give suggestions for improvement
Research Into Public Acceptance of Drone Applications in Rural Areas (Ongoing Project)
Get PDFAs unmanned aerial vehicles (UAVs) become increasingly relevant in agriculture,logistics, and emergency services, their integration into rural areas offers bothopportunities and challenges. Public acceptance is a key factor for successfulimplementation and is influenced by perceived usefulness, emotional responses,trust, and local relevance. Acceptance also varies across application fields andgeographic contexts. Despite growing interest in drone technologies, empiricalresearch on rural-specific acceptance remains limited. This study addresses thatgap by investigating public acceptance of civilian drone applications in ruralnorthern Germany, particularly in coastal regions. It explores cognitive andemotional acceptance factors, cross-sectoral differences, and developscommunication strategies to foster support. The research is part of a project cofundedby the German Federal Ministry of Education and Research (BMBF)
