Antediluvian

ABSTRACT As we move into a time of accelerated change there is a need to center ourselves and recognize our innate strengths. Through the metaphor of the Antediluvian we are reminded that humans have survived global upheaval many times. This body of work, inspired by flood mythologies, encourages those who seek guidance to look anew. The primary motifs are salt and boats. The boats are made of paper and reed; you cannot sail them, they are a device with which to visualize transcension. Salt water, (brine), represents the oceans and our dependence on both water and salt for life. It also reminds us that too much of either leads to destruction and death. Balance and sound navigation are required. This installation of encaustic paintings, sculptural objects and talismans represent encoded data informed by the non-verbal language of art intended to stimulate preparation, mentally and spiritually, for the challenges coming our way

Intra-Annual Fjord Circulation: Seasonal Variation in Fjord Physics and Biology and the Impacts of a Glacial Lake Outburst Flood

Climate change is expected to significantly affect the world’s fjords by increasing storm intensity and glacial lake outburst floods (GLOFs). GLOFs are characterized as a sudden release of glacial trapped waters into a fjord, yet how they modify fjord circulation and zooplankton migration patterns is not well understood. This study aims to investigate long-term physical and biological patterns in fjords and how they are modified by GLOFs by characterizing intra-annual variation in fjord hydrodynamics and biology. The study area is Martinez Channel in Chilean Patagonia located below the Northern Patagonia Ice Field. To accomplish this goal, circulation patterns and temporal and spatial variations of zooplankton will be analyzed in the presence of a GLOF and under normal conditions. The data collected include horizontal current velocities measured throughout the water column with a moored (~80 m depth), upward facing, acoustic doppler current profiler (ADCP) which sampled hourly in 1 m vertical bins. Salinity, temperature, wind, and river discharge data were also analyzed to complement the velocity measurements. Results showed that the baroclinic annular mode (BAM), a proxy for storminess in the Southern Hemisphere, significantly influenced the fjord every ~20-30 days. The BAM induced mixing which caused pycnocline depressions that interacted with the diel vertical migration of zooplankton. The strong winds associated with the BAM were also enough to retain floodwaters from the GLOF in early February. This study proves that external events such as the BAM and GLOFs affect fjord physics and biology and should be considered in future studies

Size Matters: The Use and Misuse of Statistical Significance in Discrete Choice Models in the Transportation Academic Literature

In this paper we review the academic transportation literature published between 2014 and 2018 to evaluate where the field stands regarding the use and misuse of statistical significance in empirical analysis, with a focus on discrete choice models. Our results show that 39% of studies explained model results exclusively based on the sign of the coefficient, 67% of studies did not distinguish statistical significance from economic, policy or scientific significance in their conclusions, and none of the reviewed studies considered the statistical power of the tests. Based on these results we put forth a set of recommendations aimed at shifting the focus away from statistical significance towards proper and comprehensive assessment of effect magnitudes and other policy relevant quantities.Comment: 14 pages, 1 table, 0 figure

Text-aided Group Decision-making Process Observation Method (x-GDP): A novel methodology for observing the joint decision-making process of travel choices

Joint travel decisions, particularly related to social activities remain poorly explained in traditional behavioral models. A key reason for this is the lack of empirical data, and the difficulties associated with collecting such data in the first place. To address this problem, we propose Text-aided Group Decision-making Process Observation Method (x-GDP), a novel survey methodology to collect data on joint leisure activities, from all members of a given clique. Through this method we are able to observe not only the outcome (i.e., the joint activity location chosen) but also the decision-making process itself, including the alternatives that compose the choice set, individual and clique characteristics that might affect the choice process, as well as the discussion behind the choice via texts. Observing such a process will allow researchers to gain a deeper understanding of the joint decision-making process, including how alternatives are weighted, how members interact with each other, and finally how joint choices are made. In this paper we introduce the results of a x-GDP survey implementation focusing on joint eating-out activities in the Greater Tokyo Area, giving a detailed overview of the survey components, execution logistics and initial insights on the data. This is to the best of our knowledge the first attempt to observe group joint travel decisions in real time through a zoom-moderated experiment.Comment: 19 pages, 8 figure

On the effect of the built environment and preferences on non-work travel: Evidence from Japan

This study uses data from the 4th Nationwide Person Trip Survey to analyse the relation between the built environment, modal access preference at residential location and travel behaviour in Japan. By estimating random parameter count models, significant statistical associations were found between the built environment and preferences with non-work trip frequency by mode. Furthermore the effect of population density, car ownership and some access preference traits were found to be heterogeneous for some modes. Since most of the recent literature has focused largely on North-American and European cities, this study contributes to the existing body of literature by examining the role of the built environment and individual preferences on travel behaviour in the context of Japanese cities, and sheds some light on existing heterogeneity in the effects of some factors related to travel behaviour

Examining Cooperative System Responses Against Grid Integrity Attacks

Smart grid technologies are integral to society’s transition to sustainable energy sources, but they do not come without a cost. As the energy sector shifts away from a century’s reliance on fossil fuels and centralized generation, technology that actively monitors and controls every aspect of the power infrastructure has been widely adopted, resulting in a plethora of new vulnerabilities that have already wreaked havoc on critical infrastructure. Integrity attacks that feedback false data through industrial control systems, which result in possible catastrophic overcorrections and ensuing failures, have plagued grid infrastructure over the past several years. This threat is now at an all-time high and shows little sign of cooling off. To combat this trajectory, this research explores the potential for simulated grid characteristics to examine robust security measures by use of a cyber-physical system (CPS) testbed constructed across the University of Central Florida (UCF) Resilient, Intelligent and Sustainable Energy Systems (RISES) Lab Cluster. This thesis explores hypothesized defense mechanisms and awareness algorithms to protect against unforeseen vulnerabilities brought on by grid attacks that will test the boundaries of commercial cybersecurity standards. Through an extensive probe across proposed defenses and vulnerability analysis of industrial systems, a blueprint for future research is outlined that will yield results that have the potential to ripple improvements across the power sector. The sanctity of critical infrastructure is of the highest priority for global powers. As such, this research bolsters the tools at the disposal of international entities and seeks to protect the ever-expanding lifestyle that reliable access to energy provides
