text: "Dieser Beitrag untersucht Liquiditätseffekte einer Vermögensteuer bei Mietwohnimmobilien.
Mithilfe von Daten einer Immobilien-Kapitalgesellschaft werden die Wirkungen einer
Vermögensteuer auf die Cashflows aus der Vermietung von Wohnimmobilien simuliert.
Der Detailgrad der Daten ermöglicht dabei Analysen auf Jahres-, Regional- und
Baujahresebene. Ein Abgleich mit weiteren Immobiliendaten untermauert die Vergleichbarkeit
und Aussagekraft der Analysen. Die Ergebnisse der Simulation zeigen, dass die
Einführung einer Vermögensteuer den Cashflow aus dem Mietgeschäft erheblich reduzieren
und zu Liquiditätsproblemen führen kann. Im Durchschnitt über alle Beobachtungen\r\nergibt
sich bei einem Vermögensteuersatz i.H.v. 2 % ein negativer Cashflow nach Berücksichtigung
aller Kosten. Generell bedeutet dies, dass wachstumsorientierte Immobilien durch
eine Vermögensteuer liquiditätsmäßig stärker belastet werden als mietrenditeorientierte
Immobilien. Insbesondere in Großstädten mit hohen Immobilienwerten, aber verhältnismäßig
geringen Mieten, können die Liquiditätseffekte mehr als dreimal so hoch ausfallen
wie in ländlichen bzw. industriell-geprägten Regionen, was zu einem relativen
Attraktivitätsverlust führen kann. Durch die Entkopplung der Vermögensteuer von
den Mieterträgen zeichnet sich eine starke Abhängigkeit der Steuerlast von aktuellen
Marktentwicklungen und dem Zinsumfeld ab, was eine zusätzliche Unsicherheit für
Investoren darstellt. Diese steuerliche Unsicherheit könnte sich potentiell auf
die Investitionsbereitschaft auswirken und sollte daher\r\nin politischen Diskussionen
über die Wiedereinführung einer Vermögensteuer berücksichtigt werden."

text: 'Abstract. This study presents intrinsic lubrication as a novel approach
to deep drawing processes, using additively manufactured, lubricant-permeable
tools to minimize lubricant consumption and improve efficiency. Two systems were
evaluated: a passive system based on capillary action and gravity, and an active
system using pumped delivery for precise, on-demand application. Experimental
tests were conducted on micro-bores (0.2-0.5 mm) to demonstrate their suitability
for lubricant transport. Smaller bores have excellent capillary action but are
prone to clogging, while larger bores offer higher permeability. The passive system
is resource-efficient but requires adjustments to counteract gravitational asymmetry.
The active system provides consistent lubricant distribution but is more complex.
These findings provide a basis for optimizing intrinsic lubrication systems.'

text: "This paper deals with the implementation and results of the application of
a multi-stage traffic light control system which includes a simulation-based traffic
estimation and model predictive control.\r\nThe traffic light control system incorporates
a fuzzy system for traffic light phase preselection, followed by a model predictive
control to optimise phase combinations and switching times. Predefined phases
are selected without restrictions in the order according to a multi-objective
optimisation to adapt to the traffic as freely as possible. Initially, the system
is tested in simulations and compared with existing methods and analysed afterwards
for its effectiveness in a prototype commissioning in field tests. Results indicate
high potentials for reducing emissions and waiting times, highlighting the system's
value. However, further refinement is necessary for standard implementation. This
comprehensive approach demonstrates advancements in traffic management technology,
showcasing the potential for enhancing urban mobility and reducing environmental
impact."

text: "One of the most important strategies for reducing CO2 emissions in the mobility
sector is lightweight construction. In particular, the car body offers several
opportunities for weight reduction. Multi-material designs are increasingly being
applied to select the most suitable material for the respective load and ultimately
achieve synergy effects. For example, aluminium castings are used at the nodes
of a spaceframe body. Subsequently, these are joined with profiles to form the
bodyshell. To join different materials mechanical joining techniques, such as
semi-tubular self-piercing riveting, are deployed. According to the current state
of the art, cracks occur in the aluminium castings during the mechanical joining
process as a result of the high degree of deformation. Although the aluminium
casting alloys of the AlSi-system exhibit low ductility, these alloys reveal excellent
castability. In particular, the ability to cast thin structural parts is enabled
by the low liquidus point of the near eutectic aluminium casting alloys.\r\nThis
study addresses the mechanical joining properties of the near eutectic aluminium
casting alloy AlSi12, depending on different microstructures. These are achieved
by annealing processes and modifying agents. Through an adapted heat treatment,
the previously lamellar morphology can be transformed into a globular morphology,
which leads to increased ductility and prevents the formation of cracks during
the self-piercing riveting (SPR). The joinability is investigated using different
die geometries, whereas the joint formation is analysed regarding crack initiation.
To evaluate the increased ductility, microstructural and mechanical tests are
performed and finally, a microstructure-joinability correlation is established."

text: The accurate prediction of crack initiation and propagation is essential for
assessing the structural integrity of mechanically joined components and other
complex assemblies. To overcome the limitations of existing finite element tools,
a modular Python framework has been developed to automate three-dimensional crack
growth simulations. The program combines geometric reconstruction, adaptive remeshing,
and the numerical evaluation of fracture mechanics parameters within a single,
fully automated workflow. The framework builds on open-source components and remains
solver-independent, enabling straightforward integration with commercial or research
finite element codes. A dedicated sequence of modules performs all required steps,
from mesh separation and crack insertion to local submodeling, stress and displacement
mapping, and iterative crack-front update, without manual interaction. The methodology
was verified using a mini-compact tension (Mini-CT) specimen as a benchmark case.
The numerical results demonstrate the accurate reproduction of stress intensity
factors and energy release rates while achieving high computational efficiency
through localized refinement. The developed approach provides a robust basis for
crack growth simulations of geometrically complex or residual stress-affected
structures. Its high degree of automation and flexibility makes it particularly
suited for analyzing cracks in clinched and riveted joints, supporting the predictive
design and durability assessment of joined lightweight structures.

text: Abstract. In the development of advanced lightweight automotive solutions,
self-piercing riveting (SPR) offers the possibility of joining multi-material
structures to fulfil a wide variety of requirements. With regard to the entire
process chain, production-related pre-deformations of the parts to be joined can
influence the geometric shape and load capacity of SPR joints. Various studies
have investigated the influence of pre-stretched sheet materials, in the sense
of pre-drawing processes, on the formation of SPR joints. The impact of pre-stretching
sheet metals on the formation of their geometrical characteristics and the shear-tensile
strength of SPR processes was observed [1]. Pre-rolled semi-finished products
are also joined together in mixed material automotive structures, e.g. tailor
rolled blanks. This work aims to investigate the influence of pre-rolled joining
parts on the geometric formation and load-carrying capacity of SPR joints. For
this purpose, sheets of metal are cold-formed using a rolling process to induce
a defined strain-hardening state in the material and then joined in various combinations.
As the degree of deformation increases, the rolling of samples can lead to minimal
accumulation of damage in the sheet materials, which can influence the joint behaviour.
The rolling process, as well as the subsequent joining process, are also investigated
by FEM. The influence of pre-rolled semi-finished products on the strength of
the SPR joints is investigated.

text: This study analyzes the impact of tariff imposition announcements on the stock
prices of 1,194 U.S. companies during the first Trump administration, using a
unique sample of 4,624 announcements made by or against the U.S. between January
2018 and August 2019. We find that tariff announcements lead to negative (cumulative)
average abnormal stock returns. These negative wealth effects occur regardless
of whether the Trump administration imposes safeguard tariffs to protect domestic
industries or foreign countries announce retaliatory tariffs. Moreover, the adverse
impact is primarily driven by announcements involving China, with variations linked
to sector-specific, tariff, trade, and firm characteristics.

text: Selecting tasks is a typical job in everyday teaching that requires teachers
to have content-specific expertise, including categories to think about and perceive
conceptual understanding. This contribution investigates the activation of prospective
teachers’ categories when solving tasks on the scalar product and evaluating their
relevance for teaching in upper secondary school. To further investigate, whether
input on content-related aspects could be helpful to promote a professional justification
for the selection of tasks, two groups with and without input are to be differentiated.
Different ways of dealing with underlying concept elements and evaluating the
relevance of tasks are discussed by examples.

text: 'Die aktuellen Ergebnisse nationaler und internationaler Vergleichsstudien
zeigen, dass etwa 25 Prozent der Lernenden am Ende der Grund-schulzeit unzureichende
mathematische Kompetenzen aufweisen, sodass ein Weiterlernen kaum möglich ist.
Es wird daher gefordert, dass sich der Mathema-tikunterricht verstärkt einer verstehensorientierten
Förderung arithmetischer Basis-kompetenzen widmen soll. Hierfür müssen Lehrkräfte
allerdings sensibilisiert, weiter- und fortgebildet werden. In diesem Beitrag
wird ein Professionalisierungs-konzept für den Mathematikunterricht der Primarstufe
vorgestellt, welches im Rah-men des bundesweiten Projekts „Schule macht stark“
(kurz: SchuMaS) entstanden ist. Konzeptionell verzahnt es im Besonderen Theorie
und Praxis: Es werden Fort-bildungen in Form von Fachnetzwerktreffen konzipiert
und durch praxisnahe Kernbotschaften wird die Anbindung an die eigene Unterrichtspraxis
ermöglicht. Darüber hinaus werden zu diesen Kernbotschaften passende Praxiserprobungen
für die unterrichtliche Umsetzung bereitgestellt und so aufbereitet, dass sie
auch für den Transfer ins Kollegium geeignet sind. Ferner werden zur vertiefenden
Ausei-nandersetzung mit zentralen didaktischen Ideen onlinebasierte Selbstlernmodule
zur Verfügung gestellt. Das Konzept wurde über drei Jahre (2021–2024) entwi-ckelt,
erprobt und evaluiert. Die Evaluationsergebnisse zum Gesamtkonzept und den einzelnen
Komponenten (Fachnetzwerktreffen, Praxiserprobung, onlineba-sierte Selbstlernmodule
und Transfer ins Kollegium) werden abschließend darge-stellt und diskutiert.'

text: "Parental Perceptions of Inclusive Teacher and School Support – Establishment
of a Short-Form \r\n\r\nThe concept of inclusive education has gained considerable
attention recently, emphasizing the importance of creating supportive educational
environments for all students. Parental perceptions play a crucial role in shaping
these inclusive climates (De Boer et al., 2010; Stevens & Wurf, 2020). However,
current measures are often neither concise nor practical for widespread application.
This study addresses this gap by developing a valid and reliable short scale for
assessing parental perceptions of inclusive education.\r\nDespite growing research
on inclusive education, there remains a lack of concise instruments that effectively
capture parental perceptions across diverse contexts. A recently developed instrument
focusing on parents’ views is the ‘Parental Perception of Inclusion Climate Scale’
(PPICS; Sharma et al., 2022). The original scale comprises 28 items representing
three factors (‘Teacher and School Support’, ‘Student Engagement’ and ‘Friendships’).
Although the original version has its advantages (broad representation of the
constructs, tested psychometric properties), a shorter version would make it even
easier to use in research and practice. Therefore, our research aims to shorten
this instrument and to demonstrate its psychometric integrity. \r\nWe used a sample
of N=4,338 parents from Germany who completed a German version of the ‘PPICS’
(Kullmann & Blankenstein, 2024; Sharma et al., 2022) online. The total sample
was randomly divided into two similar subsamples for validation. In the first
subsample, we examined factorial structure using exploratory and confirmatory
factor analyses. Our results confirmed the replication of the originally proposed
three-factor structure; however, one factor (‘Student Engagement’) was represented
by only two items with insufficient reliability, while a second factor (‘Friendships’)
included items that were not fully congruent with its intended content and had
high cross-loadings. \r\nIt was therefore decided to retain only one robust factor
(‘Teacher and School Support’) for further analysis. Items were excluded based
on item characteristics and content relevance. This resulted in an eight-item
scale, which was subsequently validated in the second subsample. The final analyses
confirmed measurement invariance across both subsamples and different federal
states as well as across parents of children with and without disabilities. These
findings suggest that the shortened scale is reliable and valid for assessing
parental perceptions of inclusive teacher and school support in different contexts.\r\nIts
application can contribute to incorporating parents' perspectives into discussions
about inclusive education. As part of a study in Switzerland in March 2025, the
short version will be tested. These results will be complemented and discussed
in the presentation.\r\nReferences \r\nDe Boer, A., Pijl, S. P., & Minnaert, A.

text: Sparsity is a highly desired feature in deep neural networks (DNNs) since
it ensures numerical efficiency, improves the interpretability of models (due
to the smaller number of relevant features), and robustness. In machine learning
approaches based on linear models, it is well known that there exists a connecting
path between the sparsest solution in terms of the $\ell^1$ norm,i.e., zero weights
and the non-regularized solution, which is called the regularization path. Very
recently, there was a first attempt to extend the concept of regularization paths
to DNNs by means of treating the empirical loss and sparsity ($\ell^1$ norm) as
two conflicting criteria and solving the resulting multiobjective optimization
problem. However, due to the non-smoothness of the $\ell^1$ norm and the high
number of parameters, this approach is not very efficient from a computational
perspective. To overcome this limitation, we present an algorithm that allows
for the approximation of the entire Pareto front for the above-mentioned objectives
in a very efficient manner. We present numerical examples using both deterministic
and stochastic gradients. We furthermore demonstrate that knowledge of the regularization
path allows for a well-generalizing network parametrization.

text: This research investigates how Artificial Intelligence (AI) can be systematically
integrated into existing business processes by combining suitable competencies
with graphical AI workflow modelling. While AI offers a high potential for automation
and increased efficiency, its implementation often fails due to a lack of interdisciplinary
competencies that bridge the gap between domain expertise and IT know-how. Low-code
platforms and visual modelling tools are increasingly recognised as enablers,
empowering non-programmers to intuitively create graphical AI- based workflows.
Nevertheless, specific competencies are required to realise the full potential
of AI, the domain specific knowledge and align technical understanding with AI
capabilities. The paper reviews the state of the art in AI-driven business process
automation and competencies for visual low-code approaches. It then presents a
practical solution to identify and systematise essential competence areas. Based
on this, a practical competence model is developed to support the design of user-friendly,
AI-enabled workflows. This is tested in a practical application context — emergency
management — where it supports critical decision-making processes and is validated
through expert feedback. The study concludes by offering actionable recommendations
to help organisations foster the necessary competencies and methods for competently
integrating AI into their digital processes.
