Artificial intelligence versus Maya Angelou:Experimental evidence that people cannot differentiate AI-generated from human-written poetry

The release of openly available, robust natural language generation algorithms (NLG) has spurred much public attention and debate. One reason lies in the algorithms' purported ability to generate human-like text across various domains. Empirical evidence using incentivized tasks to assess whether people (a) can distinguish and (b) prefer algorithm-generated versus human-written text is lacking. We conducted two experiments assessing behavioral reactions to the state-of-the-art Natural Language Generation algorithm GPT-2 (Ntotal = 830). Using the identical starting lines of human poems, GPT-2 produced samples of poems. From these samples, either a random poem was chosen (Human-out-of-the-loop) or the best one was selected (Human-in-the-loop) and in turn matched with a human-written poem. In a new incentivized version of the Turing Test, participants failed to reliably detect the algorithmically-generated poems in the Human-in-the-loop treatment, yet succeeded in the Human-out-of-the-loop treatment. Further, people reveal a slight aversion to algorithm-generated poetry, independent on whether participants were informed about the algorithmic origin of the poem (Transparency) or not (Opacity). We discuss what these results convey about the performance of NLG algorithms to produce human-like text and propose methodologies to study such learning algorithms in human-agent experimental settings.Comment: Computers in Human Behavior 202

© moments in the life of an author : scholarly publications and relevant legal actions [Copyright moments in the life of an author]

When writing an article an author encounters several moments where he is confronted with copyright whether he likes it or not or whether he is interested in the topic or not. Unfamiliarity or lack of interest with copyright can create an unbalance in the careful package of the balances which copyright is and thus hinder innovation of the process of scholarly communication. The Dutch SURF Foundation together with its British counterpart JISC have developed a © toolkit which supports and assists authors, librarians, legal offices and publishers to (re)phrase publishing agreements and copyright policies of institutions of higher education to achieve maximum access to scientific output

Landing Obligation for Dutch Fisheries: Challenges and Solutions

This presentation provides an overview of a presentation held during the Industry and Policy Day held at the IIFET 2016 Scotland conference in July 2016. The presentation was part of Session B4: LO - Government Solutions. The session was chaired by Professor Gil Sylvia and the presentation was given by Marieke Mossink.Proceedings of the Eighteenth Biennial Conference of the International Institute of Fisheries Economics and Trade, held July 11-15, 2016 at Aberdeen Exhibition and Conference Center (AECC), Aberdeen, Scotland, UK

Cracking the Vault: Generation and analysis of a MVP knockout mouse model

__Abstract__ In 1986 a novel, large-sized ribonucleoprotein complex was first described. The barrel-shaped structures were initially detected in preparations of clathrin-coated vesicles from rat liver and because they showed a morphology that resembled the vaulted ceilings in cathedrals, the structures were named vaults. It is now known that structures of similar dimension, morphology and composition are present in cells of diverse organisms like protozoa, molluscs, the slime mold Dictyostelium discoideum, echinoderms, fish, amphibians, avians, and mammals. The high degree of conservation of this large complex points to an important cellular function. Vaults could not be detected in Saccharomyces cerevisiae and are probably not present in Caenorhabitis elegans, Drosophila melanogaster and the plant Arabidopsis spec., i.e., no clear vault protein orthologs could be detected in the genomes of these organisms

COMPETITION ANALYSIS OF SPEED SKATING USING IMU’S

For feedback to be effective, we must first identify relevant performance indicators for speed skating. We instrumented the skating of 10 junior elite Dutch speed skaters with two inertial measurement units during two competition events. Contact time, stroke frequency and other parameters were derived from collected IMU data and related to performance (finish times). The manner and timing in which the skater initiates a race in the first 100 m, is predictive of the final finish time. A significant correlation was found between finish times and 1) a decrease in stroke frequency and 2) an increase of the contact time of the skate and the ice over the first 100 m of a race. These relations were robust against variations in race distances (i.e., 100, 300, 500 and 1500 m), while the directionality of the relation differed qualitatively between the 100 m sprint and the other distances. We concluded that progression in stroke frequency and contact time are relevant feedback parameters for enhancing performance in speed skating

The formation of vault-tubes: a dynamic interaction between vaults and vault PARP

Vaults are barrel-shaped cytoplasmic ribonucleoprotein particles that are composed of a major vault protein (MVP), two minor vault proteins [telomerase-associated protein 1 (TEP1), vault poly(ADP-ribose) polymerase (VPARP)] and small untranslated RNA molecules. Not all expressed TEP1 and VPARP in cells is bound to vaults. TEP1 is known to associate with the telomerase complex, whereas VPARP is also present in the nuclear matrix and in cytoplasmic clusters (VPARP-rods). We examined the subcellular localization and the dynamics of the vault complex in a non-small cell lung cancer cell line expressing MVP tagged with green fluorescent protein. Using quantitative fluorescence recovery after photobleaching (FRAP) it was shown that vaults move temperature independently by diffusion. However, incubation at room temperature (21 degrees C) resulted in the formation of distinct tube-like structures in the cytoplasm. Raising the temperature could reverse this process. When the vault-tubes were formed, there were fewer or no VPARP-rods present in the cytoplasm, suggesting an incorporation of the VPARP into the vault-tubes. MVP molecules have to interact with each other via their coiled-coil domain in order to form vault-tubes. Furthermore, the stability of microtubules influenced the efficiency of vault-tube formation at 21 degrees C. The dynamics and structure of the tubes were examined using confocal microscopy. Our data indicate a direct and dynamic relationship between vaults and VPARP, providing further clues to unravel the function of vaults
