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: 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.

text: 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.

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.'

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.

text: On finite regular graphs, we construct Patterson-Sullivan distributions associated
with eigenfunctions of the discrete Laplace operator via their boundary values
on the phase space. These distributions are closely related to Wigner distributions
defined via a pseudo-differential calculus on graphs, which appear naturally in
the study of quantum chaos. Using a pairing formula, we prove that Patterson-Sullivan
distributions are also related to invariant Ruelle distributions arising from
the transfer operator of the geodesic flow on the shift space. Both relationships
