text: Service research has evolved into an interdisciplinary research field that
bridges diverse disciplines, including information systems (IS) and marketing.
Nearly two decades ago, the service system concept was introduced as a foundational
abstraction in service research, drawing on ideas from the service-dominant logic
(S-D logic) of marketing. Despite its widespread adoption in service research,
particularly in the IS discipline, the service system concept lacks a solid theoretical
foundation. This has resulted in conceptual ambiguity and overlap with related
constructs, such as service ecosystems. Moreover, it has largely remained a static
analytical lens, insufficiently capturing dynamic service phenomena, including
value co-creation and co-destruction, as well as the emergence of institutional
arrangements. To address these limitations, we propose Luhmann’s systems theory
(LST) as a robust framework for conceptualizing service systems as autopoietic
(self-creating) systems, in which communication serves as the fundamental mechanism
that drives value co-creation. We derive five theoretical propositions from this
re-conceptualization that clarify conceptual ambiguity and allow researchers to
explore dynamic service phenomena in greater depth. Given LST’s general approach,
our conceptualization provides a theoretically grounded, interdisciplinary foundation
for advancing service research.

text: Simulating vibronic spectra is a central task in physical chemistry, offering
insight into important properties of molecules. Recently, it has been experimentally
demonstrated that photonic platforms based on Gaussian boson sampling (GBS) are
capable of performing these simulations. However, whether an actual GBS approach
is required depends on the molecule under investigation. To develop a better understanding
on the requirements for simulating vibronic spectra, we explore connections between
theoretical approximations in physical chemistry and their photonic counterparts.
Mapping these approximations into photonics, we show that for certain molecules
the GBS approach is unnecessary. We place special emphasis on the linear coupling
approximation, which in photonics corresponds to sampling from multiple coherent
states. By implementing this approach in experiments, we demonstrate improved
similarities over previously reported GBS results for formic acid and identify
the particular attributes that a molecule must exhibit for this, and other approximations,
to be valid. These results highlight the importance in forming deeper connections
between traditional methods and photonic approaches.

text: "Mathematical problem solving is a highly complex competence that needs\r\nto
be supported throughout the learning process. This study examines the role of\r\nproblem-solving
heuristics among 73 sixth-grade students in a German secondary\r\nschool (Gesamtschule).
Specifically, we focus on the empirical relationship between\r\nthe occurrence
of heuristics, their suitability, and application, as well as their contribution\r\nto
problem-solving success. To this end, we developed a heuristic training that\r\nintroduced
strategy keys (heuristic aid cards) accompanied by explanatory videos. By\r\nleveraging
variations in the successful application of the heuristics between students\r\nand
across multiple sessions (73 students in 4 training situations and 3 problems\r\nin
a final test), we discover from regression models with student and task-fixed
effects\r\nthat a successful use of heuristics (i.e., an heuristic occurred, that
heuristic had\r\na high suitability regarding the problem, and it was applied
correctly) leads to more\r\nsuccessful mathematical problem solving. Regarding
the underlying mechanism, we\r\nfind that all dimensions of heuristic use (occurrence,
suitability, and application\r\nof heuristics) are positively related to problem-solving
success. When comparing\r\nthe predictive capacity of all three aspects, we identified
the correct application of\r\nheuristics as particularly conducive for better
problem-solving success. In comparing\r\nthe group of students with high to those
with low initial math competence, we find no significant differences in the relationship
between heuristic use and problemsolving\r\nsuccess across achievement groups.
Our results emphasize the crucial role\r\nof heuristic application in mathematical
problem solving, which generally benefits\r\nstudents regardless of their overall
math competence."

text: "Abstract\r\n A fundamental
equation of state for tetramethoxysilane (TMOS) is developed based on the available
experimental data. In addition, new density and speed of sound measurements were
performed specifically for this work to improve the database. Owing to the limited
overall data set, additional thermodynamic properties were analyzed to support
the fitting procedure and ensure physically consistent behavior. Modified representations
of thermodynamic properties that are typically employed in the fitting procedure
were introduced to facilitate the application of constraints. The resulting model
provides a consistent description of the thermodynamic properties of TMOS."

abstract:
- lang: eng
text: We examine the relation between voluntary audit and the cost of debt in private
firms. We use a sample of 7420 small private firms operating in the period 2006-2022
that are not subject to mandatory audits. Firms self-select into voluntary audits
because of the economic setting (e.g., ownership complexity, export, subsidiary
status) or because firm fundamentals limit their access to financial debt. In
the outcome analyses, we find that voluntary audits result in higher, rather than
lower, interest rates with increases ranging from approximately 1.7 percentage
points, but going higher depending on the exact specification. This effect is
present regardless of the perceived audit quality (Big-4 vs. non-Big-4), consistent
across auditor types. Audited firms’ earnings are less informative about future
operating performance. Voluntary audits facilitate access to financial debt for
high-risk firms. The price paid is reflected in higher interest rates for voluntary
audits – firms with higher information/fundamental risk.

text: We investigate the role of stakeholders in the CSR reporting of non-listed
savings banks in Germany. They are established by municipal trustees and serve
clients in their distinct operating area. Reporting discretion under the Non-Financial
Reporting Directive may lead to variation in CSR reporting due to differences
in sustainability interests of banks’ stakeholders and CSR governance (e.g. existence
of a CSR manager). We document that the CSR reports and specific CSR dimensions
are intensely associated with the existence of strong CSR governance and to a
lesser extent with the interests of municipal trustees and bank clients. However,
the associations with these stakeholders are predominantly present in banks with
strong CSR governance. Our findings inform policy discussions about detailed CSR
disclosure requirements (e.g. the European Sustainability Reporting Standards)
and extension of reporting scope to firms with regional orientation and absence
of typical shareholders.
