Educating Older Drivers to Improve Acceptance and Utilization
Get PDFAs the population of older drivers continues to grow, there is an increasing need to enhance their awareness and understanding of Connected and Automated Vehicles (CAVs). This study utilized an education program aimed at improving the knowledge and awareness of older drivers about CAVs, thereby preparing them to utilize the safety features of these technologies while effectively meeting the challenges that come with them. Through data collection and analysis from study participants, the research provides valuable insights for transportation agencies and technology developers to design and develop more adaptive technologies and associated education for older drivers. The findings from this research will contribute to promoting the acceptance of CAVs among older drivers, thereby improving their social equity among technology users. Overall, this research provides an important contribution to the field of transportation and technology and provides insights for policymakers, researchers, and practitioners
Analyzing Video and ISOBUS Data to Understand Risk and Safety Practices for Roadside Mowing
Get PDFIn Indiana, roadside mowing covers 11,200 miles, presenting significant risks. The Indiana Department of Transportation (INDOT) seeks safer methods, including automated evaluations and autonomous robots. Analyzing 120 hours of video and ISOBUS data, we quantify mower interactions with the road and obstacles, finding mowers on -road up to 91% of the time in rural areas and 57% on highways. Key obstacles identified include signs and posts. This research aids in developing risk assessment models and safety evaluations, aiming to improve mowing safety and efficiency, and it supports future development of autonomous mowing technologies
Measurement and Imaging of Intra Matrix IgG Diffusion
Get PDFBovine IgG diffusion measurement by tracking the movement of the protein over time in an in-vitro matrix is motivated by the large number of protein/peptide therapeutics currently under various stages of development in the pharmaceutical industry. Many of these therapeutics are monoclonal antibodies (IgG type proteins) that are candidates for subcutaneous, intra-vitreous and intra-articular administration depending on the target of the therapeutic. Hyaluronic acid (HA) is a major constituent and determines the key attributes of the subcutaneous environment, vitreous humor of the eye and synovial fluid of the knee joint. HA exhibits varying molecular weight at these anatomic locations thereby influencing the in-vivo behavior of the injected therapeutic. This work provides a pre-clinical in-vitro tool to screen protein therapeutics and measure their diffusion in a HA matrix and predict their in-vivo outcomes. The measurement was done using a repurposed cell culture chamber containing 6 mm deep HA and the movement of triplicate 20 uL bovine IgG injection in the HA matrix was imaged by using gel imaging scanner. The imaging of bovine IgG was done label-free by activating the tryptophan residues at 280 nm and capturing the protein auto-fluorescence at 384 nm for 2-4 hours. HA matrices with varying viscosities were formulated using a single molecular weight HA lot or a blend of two HA lots of different molecular weights. IgG diffusion was measured in HA matrices of viscosities ranging from 0.2 Pa.s – 17.12 Pa.s. HA is a shear thinning non-Newtonian fluid and the blends ensure formulation of HA with the desired viscosity. The IgG diffusion decreases as the HA viscosity increases for measurements done in high viscosity HA (above 5 Pa.s). IgG diffusion is anomalous in the low viscosity HA (below 5 Pa.s) owing to the extremely fast diffusion and external disturbances that hinder the protein movement, thus impacting the imaging. The IgG diffusion measurement in high viscosity HA agrees with the general inversely proportional relationship between viscosity and diffusion coefficient. We are currently studying diffusion of proteins in low viscosity HA matrices
Education for Moral Judgment: Situational Creativity and Dewey’s Aesthetics
No full textThis paper argues that moral judgment is suffering at the hands of instrumental rationality and identity thinking, concepts from the tradition of the Frankfurt School of Critical Theory that help explain degradations in human relations. These concepts are not new, but they are realized in novel ways, and the implications continue to be significant, contributing to human suffering and prominent anti-intellectual sentiment. Working through the shared intellectual ground of Adorno, Edmundson, Stivers, and Ellul, the paper takes a critical look at our culture through the objectification of genuine human relations that comes with techno-rational prioritization. The endpoint of such a culture is the compromise of human subjectivity in the service of efficiency, objectivity, and measurability. Extending the analysis to educational practice, Joas’s notion of situational creativity and Dewey’s aesthetics are proposed as possible points of resistance, highlighting positive actions to be taken to remediate these narrow and dehumanizing phenomena
Deficiencies in Safe Practices by Pilots Operating General Aviation Aircraft in Weather Conducive for Icing
Get PDFIntroduction: Flights of general aviation aircraft in icing conditions pose safety hazards especially since few airplanes are equipped with ice protection systems (FIKI). Herein, we sought to answer the following questions not previously addressed: (i) Has the general aviation icing-related accident rate declined over time? (ii) Which phase(s) of flight lead(s) to the highest fraction of fatal accidents? (iii) Do general aviation pilots adhere to safe practices when operating in forecasted icing? Methods: Retrospectively, icing-related accidents were per the National Transportation Safety Board database. Prospectively, non-FIKI single-engine airplanes, operating in forecasted icing, were tracked (January–March 2023) using FlightAwareR. Presumptive icing was determined with METARs/modelled Skew-T data. Statistical tests employed Poisson distributions/Pearson chi-square analyses. Results: In a retrospective analysis, despite a nonstatistical (p=0.621) downward trend in icing-related accidents (2000–2019), over half of mishaps were fatal, a fraction unchanged (p=0.842) over the two decades. Loss-of-control represented the terminating event with the highest proportion of fatal outcomes (85%). Accidents involving takeoff-climb ice accretion were overrepresented for fatal outcomes (66%). In a prospective study arm, of 300 non-FIKI flights operating in forecasted icing and tracked in real time, 65% departed or descended/landed (44%) in presumptive icing.Conclusions: A modest downward trend in icing-related accident rate and an undiminished high fraction of fatal mishaps rationalize focused training of pilots operating non-FIKI aircraft in areas prone to icing. Specifically, two novel observations warrant emphasis: (i) an approximately threefold higher icing-related fatal accident fraction compared with all general aviation accidents and (ii) the high proportion of lethal mishaps due to takeoff-climb ice accretion
Design Students’ Perspectives on Safety Concerns when Designing Future Tourism Services
Get PDFThe safety of services is essential part of a company\u27s social responsibility. In the tourism industry, ensuring the safety of services is crucial, but often overlooked in the design process. Incorporating safety aspects during the initial design phase can eliminate potential safety issues and improve quality of the services. By addressing safety concerns early on, unnecessary worries related to activities and services can be resolved. This paper examines the design perspective on safety in Lapland outdoor activities. Two studies were conducted with art and design students, including an online survey to identify safety concerns in various tourist scenarios, and a focus group study on safety design. The study produced themed safety concerns on psychological, physical, social, financial, personal data, communication, and environmental safety factors. Safety design is an increasingly relevant topic in the future. When committing safety aspects in design, it can eliminate potential safety issues and improve tourists\u27 trust between the service provider and the customer. Through safety design, it is possible to enhance the customer experience, develop social sustainability in services, and create additional value for the customer
