  text: 'We investigate how verbal and nonverbal linguistic features, exhibited by
    speakers and listeners in dialogue, can contribute to predicting the listener''s
    state of understanding in explanatory interactions on a moment-by-moment basis.
    Specifically, we examine three linguistic cues related to cognitive load and hypothesised
    to correlate with listener understanding: the information value (operationalised
    with surprisal) and syntactic complexity of the speaker''s utterances, and the
    variation in the listener''s interactive gaze behaviour. Based on statistical
    analyses of the MUNDEX corpus of face-to-face dialogic board game explanations,
    we find that individual cues vary with the listener''s level of understanding.
    Listener states (‘Understanding’, ‘Partial Understanding’, ‘Non-Understanding’
    and ‘Misunderstanding’) were self-annotated by the listeners using a retrospective
    video-recall method. The results of a subsequent classification experiment, involving
    two off-the-shelf classifiers and a fine-tuned German BERT-based multimodal classifier,
    demonstrate that prediction of these four states of understanding is generally
    possible and improves when the three linguistic cues are considered alongside
    textual features.'

  text: "<jats:title>Abstract</jats:title>\r\n                  <jats:p>We consider
    Brownian motion with partial resetting, which has recently attracted a lot of
    attention in physics as well as the mathematics literature. We analyze the speed
    of convergence of this process towards stationarity as well as its quasistationary
    behavior. In particular, we prove the existence of a Yaglom limit and hence of
    a minimal quasistationary distribution. We use these results to study our main
    topic, namely the process conditioned on staying positive using methods which
    are well adapted to this specific process. It turns out that this process can
    be described explicitly as a three‐dimensional Bessel process with partial resetting
    with the same parameter but a modified resetting rate. This can be interpreted
    as an effect due to entropic repulsion.</jats:p>"

  text: "Large intermediate results can cause join queries to run unexpectedly long.
    This problem is particularly common for analytical queries, which aggregate data
    over many tables to produce a comparatively small final output, and queries on
    graph data, where intermediate results blow up quickly. Recent work inspired by
    Yannakakis’ algorithm approaches this by modifying the query engine to avoid materializing
    unnecessary tuples. However, this requires significant changes to the core of
    the system, which is not feasible in many situations such as cloud environments
    or proprietary systems.\r\nIn this work, we propose a flexible approach for optimizing
    long-running join queries from the outside of the DBMS. Rewriting-based realizations
    of Yannakakis’ algorithm suffer from inherent overhead due to the creation of
    intermediate tables. Thus, we present an approach for detecting and targeting
    queries which would benefit from a Yannakakis-style optimization. We introduce
    a new benchmark combining 5 standard benchmarks and augmenting them with additional
    instances, which provides a sufficient size and diversity for a machine learning
    based solution. On PostgreSQL, DuckDB and SparkSQL, slowdowns on queries where
    the rewriting is counterproductive are mostly avoided, as opposed to a naïve application
    of the rewriting, and we observe significant improvements in end-to-end runtimes
    over standard query execution and unconditional rewriting."

  text: In this paper, we discuss the application of retrospective video recall for
    the assessment of cognitive processes in explanatory interactions, such as understanding
    and mental models. Our purpose is to reflect on the benefits and limitations of
    video recall compared to another self-report method, ‘thinking-aloud’. To do so,
    we reveal empirical results from the application of video recall in three interdisciplinary
    research projects that applied the method for the qualitative and quantitative
    assessment of cognitive and behavioral phenomena in everyday explanations. In
    all three projects, video recall was applied as a post-hoc procedure following
    the recording of dyadic face-to-face explanations of board games. The design of
    the video recall procedure differed between individual projects because they pursued
    different research objectives – that is the investigation of (1) an interlocutor's
    multimodal signals of understanding, (2) the change in assumptions about an interlocutor's
    dispositional and situational knowledge, and (3) the differentiated assessment
    of an interlocutor's developing understanding of domain knowledge aspects by distinguishing
    between mechanistic and functional explanatory stances. By discussing the benefits
    and the limitations of each procedure, this article provides critical reflections
    on video recall as a versatile research method applied for the analysis of human
    multimodal behavior in interaction and cognitive processing.

  text: <jats:p>The aggregation of rating metrics in reputation systems is crucial
    for mitigating information overload by condensing customer rating distributions
    into singular valence scores. While platforms typically employ technical aggregation
    functions, such as the arithmetic mean to capture product quality, it remains
    unclear whether these functions align with customers' innate aggregation patterns.
    To address this knowledge gap, we designed a controlled economic decision experiment
    to elicit customers' aggregation principles by analyzing their product ranking
    decisions and contrasting these with various reference functions. Our findings
    indicate that, on average, customers aggregate rating information in accordance
    with the arithmetic mean. However, a granular analysis at the individual level
    reveals significant heterogeneity in aggregation behavior, with a substantial
    cluster exhibiting binary patterns that focus equally on negative (1-2 star) and
    positive (4-5 star) ratings. Additional clusters concentrate on negative feedback,
    particularly 1-star ratings or 1-2 star ratings collectively. Notably, these inherent
    aggregation patterns exhibit stability across variations in numerical information
    presentation and are not significantly influenced by individual characteristics,
    such as online shopping experience, risk attitudes, or demographics. These findings
    suggest that while the arithmetic mean captures average consumer behavior, platforms
    could benefit from offering customizable aggregation options to better cater to
    diverse user preferences for processing rating distributions. By doing so, platforms
    can enhance the effectiveness of their reputation systems and improve the overall
    quality of decision-making for consumers.</jats:p>

  text: <jats:p>In many Western societies, mass immigration has been one of the most
    divisive policy issues in recent years. Seemingly moderate inflows of migrants
    can have substantial demographic consequences in the long run, due to (1) higher
    fertility of the migrant population, (2) its younger age distribution, and (3)
    the possibility of family reunification. Yet, demography hardly appears in the
    policy debate, even in media outlets that are critical of mass immigration. This
    may indicate that the mechanics of population dynamics are not widely understood.
    We design a laboratory experiment in which we confront subjects with 30 different
    migration scenarios. Subjects have to decide when to stop a given inflow of migrants
    to achieve a target share of migrants after 60 years. In line with all our pre-registered
    hypotheses, in scenarios that contain elements of usual mass immigration the growth
    of the migrant population is systematically underestimated. This bias is even
    stronger in scenarios that closely resemble the German situation since the opening
    of the borders during the 2015 refugee crisis.</jats:p>

  text: 'Traditional dyadic customer-provider interactions are being shifted to polyadic
    interactions involving diverse participants in digital service ecosystems. Especially,
    artificial intelligence (AI) is increasingly integrated into these ecosystems,
    so that they comprise non-human participants (e.g., AI-based chatbots)—fundamentally
    altering the nature of value (co-)creation. While existing literature examines
    human-to-human interactions, knowledge of service interactions between human actors
    and AI-based systems is still underexplored. To address this research gap, we
    develop a taxonomy, comprising six iterations, that explores the peculiarities
    of AI as either a resource or a (non-human) agent in digital service ecosystems.
    We evaluate our taxonomy using a multiple case study and derive the four archetypes
    of AI in digital service ecosystems: (1) discriminative experience enhancer, (2)
    protective ecosystem orchestrator, (3) ecosystem innovation companion, and (4)
    personalized service composer. Our results extend the knowledge on service science
    by showing how AI-based systems—discriminative or generative, and focusing on
    the interaction in the ecosystem or the individual service encounter—assume the
    role of resources and non-human agents. Researchers and practitioners can utilize
    our results to augment their ecosystems with AI.</jats:p>'

  text: The governance of emerging technologies with increased autonomy in the military
    has become a topical issue in recent years, especially considering the rapid advances
    in artificial intelligence and related innovations in computer science. Despite
    this hype, the postcolonial subject’s position has been seen as secondary, often
    associated with victimhood or obscurity. By shifting the narrative to highlight
    the postcolonial subject’s agency—not only in providing real-world examples of
    artificial intelligence use in the military but also in knowledge creation and
    shaping the discourse on governance within the international, this paper contributes
    to an area of research that is often overlooked. The paper unpacks the norm-making
    efforts of postcolonial subjects regarding emerging military technologies. In
    doing this, the paper aims to advance postcolonial theory by showing how the dynamics
    of governing emerging military technologies intertwine with postcolonial subjectivity
    and to broaden the academic discussion on the governance of emerging military
    technologies and algorithmic violence, which has so far been dominated by Western
    or universalistic discourse.

  text: We investigate dispersive and Strichartz estimates for the Schrödinger equation
    involving the fractional Laplacian in real hyperbolic spaces and their discrete
    analogues, homogeneous trees. Due to the Knapp phenomenon, the Strichartz estimates
    on Euclidean spaces for the fractional Laplacian exhibit loss of derivatives.
    A similar phenomenon appears on real hyperbolic spaces. However, such a loss disappears
    on homogeneous trees, due to the triviality of the estimates for small times.
