No full textNach dem Autor vorliegendem noch sehr lückenhaften und zumeist von alten Museumsbälgen stammenden Material werden die folgenden auf dem Braunbrusttalegalla Aepypodius bruijnii (Oustalet, 1880) nachgewiesenen Federlinge beschrieben: die Amblyceren Kelerimenopon aepypodi Price & Emerson, 1966 sensu lato und Talegalligogus wilhelmi waigeuensis n. ssp. und die Ischnoceren Megathellipeurus mumesensis n. sp., „Oxylipeurus“ aepypodius Clay, 1938, Talegallipeurus tenuis Mey, 1983, Weehalia hakalphilus n. sp. und Homocerus sp. Diese Arten weisen auf enge verwandtschaftliche Beziehungen ihrer Wirtsgattungen Aepypodius und Talegalla, denen Alcetura ferner steht. Unter besonderer Berücksichtigung von Aepypodius arfakianus und A. bruijnii wird die hospitale Verbreitung aller bisher auf Großfußhühnern (Megapodiidae) festgestellten amblyzeren und ischnozeren Federlingsgattungen zur Übersicht gebracht.Stichwörter

These species illustrate the close relationships between their host genera Aepypodius and Talegalla, and suggest that Alectura is more distantly related. An overview is given of the hospitalic distribution of all genera of chewing lice so far known off the Megapodiidae, with special reference to Aepypodius arfakianus and A. bruijnii.Keywords

침묵시키지 않기: 임흥순의 캄보디아 [Not Silencing. Im Heung-soon’s Cambodia]
Get PDFIn Adeena Mey's essay, "Not Silencing: Im Heung-soon’s Cambodia," the author delves into the complexities of cultural, historical, and political dynamics intertwined in Im Heung-soon’s documentary "Factory Complex" (2014–15). Mey reflects on his experience of using the film as a pedagogical tool and explores the significance of understanding Asian contexts to fully engage with it. Through the lens of his multicultural classroom setting, Mey contemplates the film's international relevance, particularly in relation to Asian socio-economic differences and linguistic nuances. He discusses Im’s depiction of the shared struggles of female workers in South Korea and Cambodia, highlighting the interplay of historical, economic, and political factors shaping their experiences.
Mey underscores the film’s ability to resonate with experiences of displacement and migration, and examines the documentary "A Cambodian Spring" (2017) by Chris Kelly, which portrays the activism of Cambodian citizens amidst socio-political challenges. He critiques the film’s portrayal of empowerment, questioning whether it truly amplifies the voices of its protagonists or falls into a narrative of Western interventionism.
Through nuanced comparisons between Im's and Kelly's documentaries, Mey delves into the complexities of representation and agency within socio-political narratives. He highlights Im’s approach to depicting the struggles of Cambodian workers without oversimplifying their experiences or succumbing to Western-centric narratives. Mey emphasizes Im’s ability to capture the transnational dimensions of labour exploitation while giving agency to marginalised voices.
Furthermore, Mey explores Im’s cinematic language and its political implications, drawing on theoretical frameworks by scholars like Edward Said and Gayatri Spivak. He contends that Im's documentary offers a nuanced portrayal of labour struggles without resorting to messianic narratives or oversimplified empowerment tropes. By weaving together insights from film theory, cultural studies, and political discourse, Mey offers a comprehensive analysis of Im Heung-soon’s "Factory Complex" and its significance within broader discussions of art, activism, and representation

Molecular evolution and phylogenetics of circular single-stranded DNA viruses
No full textViruses infect a wide variety of hosts across all domains of life. Despite their ubiquity, and a long history of virus research, fundamental questions such as what constitutes a virus species, and how viruses evolve and are modeled, have yet to be adequately answered. We compared viral sequences across five genomic architectures (single- and double-stranded DNA and RNA) and demonstrate the presence of substitution bias, especially in single-stranded viruses. Most striking is a consistent pattern of over-represented cytosine-to- thymine substitutions in single-stranded DNA (ssDNA) viruses. This led us to question the validity of using time-reversible nucleotide substitution models in viral phylogenetic inference, as these models assume equal rates of forward and reverse substitutions. We found that an unrestricted substitution model fit the data better for most single- and double-stranded viral datasets, as measured by corrected Akaike Information Criterion, and hierarchical likelihood ratio test scores. We also approached the question of virus species identification by examining members of the most species-rich viral genus Begomovirus (Family Geminiviridae), which are circular single-stranded DNA (ssDNA) viral crop pathogens transmitted by whitefly vectors. We used novel sweet potato-infecting begomoviruses (sweepoviruses) collected during a recent vector-enabled metagenomic survey to evaluate the concept of pairwise percent nucleotide identity threshold as a criterion for species demarcation. We demonstrate that species demarcation based on pairwise percent nucleotide identities group divergent sweepovirus clusters together, and is highly influenced by when, and how much sampling occurs.Ph.D.Includes bibliographical referencesby Yee Mey Sea
Improved Generalization in Semi-Supervised Learning: A Survey of Theoretical Results
No full textSemi-supervised learning is the learning setting in which we have both labeled and unlabeled data at our disposal. This survey covers theoretical results for this setting and maps out the benefits of unlabeled data in classification and regression tasks. Most methods that use unlabeled data rely on certain assumptions about the data distribution. When those assumptions are not met, including unlabeled data may actually decrease performance. For all practical purposes, it is therefore instructive to have an understanding of the underlying theory and the possible learning behavior that comes with it. This survey gathers results about the possible gains one can achieve when using semi-supervised learning as well as results about the limits of such methods. Specifically, it aims to answer the following questions: what are, in terms of improving supervised methods, the limits of semi-supervised learning? What are the assumptions of different methods? What can we achieve if the assumptions are true? As, indeed, the precise assumptions made are of the essence, this is where the survey's particular attention goes out to.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Pattern Recognition and Bioinformatic

Environment Shift Games: Are Multiple Agents the Solution, and not the Problem, to Non-Stationarity?
No full textMachine learning and artificial intelligence models that interact with and in an environment will unavoidably have impact on this environment and change it. This is often a problem as many methods do not anticipate such a change in the environment and thus may start acting sub-optimally. Although efforts are made to deal with this problem, we believe that a lot of potential is unused. Driven by the recent success of predictive machine learning, we believe that in many scenarios one can predict when and how a change in the environment will occur. In this paper we introduce a blueprint that intimately connects this idea to the multiagent setting, showing that the multiagent community has a pivotal role to play in addressing the challenging problem of changing environments.Interactive Intelligenc
