    The Memorability of Supernatural Concepts: Effects of Minimal Counterintuitiveness, Moral Valence, and Existential Anxiety on Recall

    Within the cognitive science of religion, some scholars hypothesize (1) that minimally counterintuitive (MCI) concepts enjoy a transmission advantage over both intuitive and highly counterintuitive concepts, (2) that religions concern counterintuitive agents, objects, or events, and (3) that the transmission advantage of MCI concepts makes them more likely to be found in the world’s religions than other kinds of concepts. We hypothesized that the memorability of many MCI supernatural concepts was due in large part to other characteristics they possess, such as their frequent and salient association with moral concerns and the alleviation of existential anxieties, and that without such characteristics they would fail to be memorable. We report the results of three experiments designed to test the relative contributions of minimal counterintuitiveness, moral valence, and existential anxiety to the memorability of supernatural ideas. We observed no main effects for minimal counterintuitiveness but did observe main effects for both moral valence and existential anxiety. We also found that these effects did not seem to stem from the greater visualizability of morally valenced concepts or concepts that concerned existential anxieties. These findings challenge important claims made by leading researchers regarding MCI concepts within the cognitive science of religion

    Market Power and Efficiency in a Computational Electricity Market with Discriminatory Double-Auction Pricing

    This study reports experimental market power and efficiency outcomes for a computational wholesale electricity market operating in the short run under systematically varied concentration and capacity conditions. The pricing of electricity is determined by means of a clearinghouse double auction with discriminatory mid-point pricing. Buyers and sellers use Roth-Erev individual reinforcement learning to determine their price and quantity offers in each auction round. It is shown that market microstructure is strongly predictive for the relative market power of buyers and sellers, and that high market efficiency is generally attained. These findings are robust for tested changes in individual learning parameters. It is also shown that similar relative market power findings are obtained if the electricity buyer and seller populations instead each engage in social mimicry learning via a genetic algorithm. However, market efficiency is substantially reduced.Wholesale electricity market, Electricity restructuring, Double auction, Market power, Efficiency, Concentration, Capacity, Agent-based computational economics, Roth-Erev reinforcement learning, Genetic algorithm social learning.

    Market Power and Efficiency in a Computational Electricity Market with Discriminatory Double-Auction Pricing

    This study reports experimental market power and efficiency outcomes for a computational wholesale electricity market operating in the short run under systematically varied concentration and capacity conditions. The pricing of electricity is determined by means of a clearinghouse double auction with discriminatory midpoint pricing. Buyers and sellers use a modifed Roth-Erev individual reinforcement learning algorithm to determine their price and quantity offers in each auction round. It is shown that high market efficiency is generally attained, and that market microstructure is strongly predictive for the relative market power of buyers and sellers independently of the values set for the reinforcement learning parameters. Results are briefly compared against results from an earlier electricity study in which buyers and sellers instead engage in social mimicry learning via genetic algorithms.

    Studies on the Modular Evolution of Genes

    Gene evolution is primarily studied through the observations of comparative cumulative point mutations between homologs. Genes also evolve through “remodelling”, the process of repurposing and reorganising genes and gene fragments into novel sequences. Gene remodelling is a relatively underappreciated evolutionary concept. Remodelling events circumscribe the development of novel sequences via fusion or fission events and through the shuffling of exons or domains. To date, all studies into remodelling have focussed on specific remodelling events, for example gene fusions in cancer samples, or have used small datasets (<15 species). As such, a comparative remodelling analyses between two taxonomic Kingdoms has yet to be completed. In 2018, CompositeSearch was developed to overcome the computational bottlenecks associated with mining all possible combinations that may attribute to remodelling events. We used CompositeSearch to investigate the comparative extent of remodelling within large fungal (107 species) and plant (50 species) datasets. We observed approximately 50% of fungal genes and 61% of plant genes to have a history of remodelling despite robust controls against Type I errors. We observed the rate of remodelled family birth and decay to be clocklike in both datasets, and that remodelled genes were considerably more homoplastic than non-remodelled genes. Functional overrepresentation analysis concluded that remodelled genes were associated with rapidly evolving systems, such as secondary metabolism, and with phenotypic novelty, such as flowering in angiosperms. Remodelling events have been associated with the development of antimicrobial resistance (AMR). As CompositeSearch does not discern between a fusion event and any other remodelling event, we developed CompositeBLAST to detect novel AMR fusion events. CompositeBLAST was considerably faster and more sensitive than previously published fusion detection tools. Using this software, we detected previously unreported mupirocin and vancomycin resistance genes as being derived from remodelling events

    Effect of Lighting on Performance of Tasks Requiring Near Vision in Older Adults

    With age, more light is needed in order to function, but the effect of lighting on occupational performance has received little attention in occupational therapy. The purpose of the study was to determine if lighting affects older adults’ ability to perform selected occupational tasks, which require near vision and if lighting levels affects their perceived effort while performing selected occupational tasks. A quasi-experimental, repeated measures design was used with a convenience sample recruited from a retirement community. Thirty participants met the inclusion criteria, which included visual and cognitive screening. The mean age of the 30 participants was 83 years, and most (80%) were female. Participants completed three occupational tasks (reading a prescription label, sorting pills, and sorting dark colored socks) under three different lighting levels (low, M = 103; medium, M = 127; and high, M = 397 footcandles [fc]) presented in random order. Participants were placed in three groups based on order of lighting presentation and completed each set of tasks four times: a trial session, followed by three timed sessions. Participants were asked to rate their perceived effort under each lighting level using a self-report scale. Descriptive statistics were used to examine completion times, groups, and lighting levels. In general, participants required longer to complete occupational tasks and reported more effort when utilizing medium light levels (M = 127 fc) provided by ambient lighting and a floor lamp and performed best under high lighting levels (M = 397 fc) provided by ambient lighting as well as a floor lamp and task lamp. The results suggest lighting may have affected performance and perceived effort of older adults while completing the visually challenging tasks

    Admiralty- Twilight Zone In Workmen\u27s Compensation - Pursuit of State Common Law Action Against Employer

    Get PDF
    Petitioner was injured on his employer\u27s barge moored in navigable waters while assisting in a loading operation. The employer was insured solely under the Federal Longshoremen\u27s and Harbor Workers\u27 Act. Instead of pursuing the remedy available under the federal act, petitioner brought the common law action authorized by state workmen\u27s compensation legislation in the state courts. The Oregon Supreme Court affirmed judgment for the employer on the ground that the injury was covered exclusively by the federal act. On certiorari to the United States Supreme Court, held, reversed per curiam, two justices dissenting. The injury was incurred within the twilight zone in which the election of forum by the claimant will be judicially respected. The applicability of the state law is not determined by the scope of the employer\u27s insurance coverage. Hahn v. Ross Island Sand & Gravel Co., 358 U.S. 272 (1959)
