    Thesis for sale [Podcast]
    (2024) Bartneck, Christoph
    What do you do if somebody else publishes your thesis as a book? This is what happened to Andrew Vonasch. Together, we investigated this new type of scam. We discovered a flood of stolen theses and the thieves’ method to publish them on Amazon and through other resellers. I interviewed Richard Elliott and sought legal advice from Ursula Cheer. We confronted IngramSpark with this scam. They removed the theses from their system but made it practically impossible to prosecute the offenders.

    Humanoidization: Costs, Demand, and the Future of Work [Podcast]
    (2024) Bartneck, Christoph; Allan D
    Humanoid robot companies are promising that humanoids will fast become our friends, colleagues, employees, and the backbone of our workforce. As Elon Musk described it when he first unveiled Tesla's Optimus: "It will upend our idea of what the economy is... it will be able to do basically anything humans don't want to do... it's going to bring an age of abundance." But how close are we to this reality? What are the key costs associated with operating a humanoid? Can companies deploy them profitably? Will humanoids take our jobs, and if so, what should we be doing to prepare? To explore these questions, Dwain Allan and I interviewed Will Jackson, Jo Cribb, and Bruce McDonald.

    Assessing the Validity of the Quartile Risk Model of Dissociation for Predicting Deliberate Self-Harm
    (Informa UK Limited, 2019) Dorahy, Martin; Carrell, JM; Thompson, N
    Deliberate self-harm (DSH) involves a physical act with the intent of harming the self. There are many precipitants to this behavior, with dissociation receiving increasing attention. The current study examined the quartile risk model for predicting deliberate self-harm, which proposes that four quadrants of dissociation (low normative, high normative, low clinical, and high clinical) represent varying levels of risk for engagement in DSH. The model posits that quadrants one and three (low normative, low clinical), protect against engagement in deliberate self-harm. Quadrants two and four (high normative, high clinical), represent an increased risk of engaging in DSH. The current study also investigated the association between shame and deliberate self-harm. College students (n = 247) completed measures assessing trait dissociation, state and trait shame, and deliberate self-harm. Results did not support the quartile risk model, rather they suggested a general increasing level of deliberate self-harm with heightened dissociation. Furthermore, trait shame was significantly associated with deliberate self-harm. Significantly more state shame was found to occur before engaging in deliberate self-harm relative to after. Results suggest shame and dissociation are related to increased DSH.

    Trait-habitat associations explain novel bird assemblages mixing native and alien species across New Zealand landscapes
    (Wiley, 2022) Barnagaud, JY; Brockerhoff, Eckehard G.; Mossion, R; Dufour, P; Pavoine, S; Deconchat, M; Barbaro, L; Thomassen H
    Aim: Species introductions have reshaped island faunas for the last 200 years, often threatening native biodiversity. Approximately equal numbers of native and alien species currently co-occur in the New Zealand avifauna, but they show distinct habitat use. Antagonistic interactions, habitat affinities and legacies of introduction history may concur to explain their segregation along habitat gradients. To investigate these processes, we explored how habitat, ecological traits and introduction history relate with the current composition of bird assemblages. Location: New Zealand. Taxon: Birds. Methods: We analysed 917 bird point counts spread along habitat and elevation gradients in the Canterbury region, South Island and related 10 ecological traits to landscape composition using a three-table ordination method known as “RLQ analysis”, accounting for spatial autocorrelation and phylogeny. We tested whether alien species’ positions in the RLQ were related to proxies of introduction history. Results: Eighteen endemic, 11 native and 19 alien species were distributed along a gradient from forest to open-habitat assemblages, in relation to foraging mode, nesting site and body size. A second gradient segregated species between native and exotic forests according to territoriality, sedentarity and diet. Traits accounted for the separation of native and alien bird species in forests, but not in open habitats. Phylogenetic signals emerged from the separation of native and alien species by forest type, and spatial structures suggested a landscape-level, rather than regional or local determinism. These correlations were independent of introduction history, although open-habitat assemblages tended to host alien species introduced later in time. Main conclusions: Habitat type and resource availability explain the spatial partitioning of New Zealand bird assemblages between native and alien species more consistently than competitive exclusion. We conclude that trait-mediated ecological differences among species have likely played a predominant role in species’ segregation among landscapes, while maintaining endemic bird assemblages in native forests.

    Sexual selection on non-ornamental traits is underpinned by evidence of genetic constraints on sex-biased expression in dusky pipefish
    (2024) Tosto N; Rose E; Mason H; Mank J; Flanagan, Sarah
    Species without dimorphic secondary sex characteristics easily visible to humans, such as diference in size or morphology, are expected to experience low levels of sex-specifi c selection. However, monomorphism in classic visible traits could be a result of genetic or physiological constraints that prevent the sexes from reaching divergent fi tness optima. Additionally, biochemical and molecular work has revealed a variety of less easily observed phenotypes that none-the-less exhibit profound dimorphism. Sex- specifi c selection could act on these more subtle, less visible, traits. We investigate sex-specifi c selection in the polygynandrous dusky pipe sh (Syngnathus oridae), which lacks size, color, and morphological dimorphism. Using experimental breeding populations, we revealed that although males and females have similar opportunities for sexual selection, only males experience signi ficant sexual selection pressures on body size. We also investigated patterns of sex-biased and sex-specifi c gene expression in gonads, livers, and gills, and tested whether genes with highly divergent expression patterns between the sexes are more likely to be tissue specifi c, and therefore relieved of genetic constraints. We. Sex-bias in gene expression was widespread, although the reproductive organs had the most sex-biased and sex-specifi c genes. Sex-specifi c selection on gene expression in gills was primarily related to immune response, whereas the liver and gonads had a wide variety of cellular processes, as well as reproductive proteins, showing sex-biased expression. These sex-biased genes are likely less constrained by pleiotropy, as they were more organ-speci fic in their expression patterns. Altogether, we nd evidence for ongoing and historical sex-specifi c selection in the dusky pipe sh.

    Cyclic Heat Transfer Solver for OpenFOAM
    (OpenCFD Ltd, 2023) Coe, Michael; Holland, Daniel
    Channels with periodically repeating geometries are often simulated using periodic or cyclic boundary conditions. By calculating the temperature and flow field in one periodic module, the resulting distributions can be generalized to multiple modules. This reduces the computational load by simulating a single module versus the whole structure. This is a particularly useful approach when performing large optimisation studies of periodic geometries, such as compact heat exchangers. Currently, OpenFOAM only supports cyclic boundary conditions for pressure and momentum, but not heat transfer. The present work introduces a steady and an unsteady solver for cyclic heat transfer with constant wall temperature boundary conditions. The solver is validated against analytical Hagen-Poiseuille flow and two configurations of periodic wavy channels. In the latter case, the results are compared to existing literature.
