               <jats:p>The phenomenon of entanglement is the basis of quantum information and quantum communication processes. Entangled systems with a large number of photons are of great interest at present because they provide a platform for streaming technologies based on photonics. In this paper we present a device which operates with four-photons and based on the Hong–Ou–Mandel interference. The presented device allows to maximize the degree of spatial entanglement and generate the highly entangled four-dimensional Bell states. Furthermore, the use of the interferometer in different regimes leads to fast interference fringes in the coincidence probability with period of oscillations twice smaller than the pump wavelength. We have a good agreement between theoretical simulations and experimental results.</jats:p>}},

  abstract     = {{Polymer Laser Sintering (LS) is one of the most used Additive Manufacturing (AM) technologies for the tool-less production of polymer parts. The raw material is a polymer powder which is melted layerwise by the use of laser energy. Especially for the production of single parts, small series, individualized and complex structures, the technology is yet established in few branches. However, inhomogeneous and hardly controllable thermal effects during manufacturing limit the build reproducibility. The present work focuses on temperatures within so-called part cakes, their time dependency and their influence on process quality. Therefore, a temperature measurement system is implemented into a commercial laser sintering machine. Based on the experimental data a model to simulate heat transfer within part cakes is set up. Individual thermal histories during processing are successfully correlated with position dependent powder ageing effects. Another focus is on the analysis of a recycling optimized material. First results of correlations between thermal histories and part properties are shown in order to provide an outlook to further research. The data and knowledge gained through this work can be used to understand thermal effects in greater depth and to increase the process quality via optimizations.}},

  abstract     = {{Artificial intelligence (AI) has the potential for far-reaching – in our opinion – irreversible changes.
They range from effects on the individual and society to new societal and social issues. The question arises
as to how students can learn the basic functioning of AI systems, what areas of life and society are affected
by these and – most important – how their own lives are affected by these changes. Therefore, we are developing and evaluating school materials for the German ”Science Year AI”. It can be used for students of all
school types from the seventh grade upwards and will be distributed to about 2000 schools in autumn with
the support of the Federal Ministry of Education and Research. The material deals with the following aspects
of AI: Discussing everyday experiences with AI, how does machine learning work, historical development
of AI concepts, difference between man and machine, future distribution of roles between man and machine,
in which AI world do we want to live and how much AI would we like to have in our lives. Through an
accompanying evaluation, high quality of the technical content and didactic preparation is achieved in order
to guarantee the long-term applicability in the teaching context in the different age groups and school types.
In this paper, we describe the current state of the material development, the challenges arising, and the results
of tests with different classes to date. We also present first ideas for evaluating the results.}},

Verfiel die westdeutsche Steuermoral schon damals? Wie veränderte sie sich im Zeitraum zwischen 1945 und 1953? Nach einem kurzen Überblick über die Geschichte der interdisziplinären Steuermoralforschung und einigen methodischen Überlegungen, wie Historiker*innen die Entwicklung der Steuermoral qualitativ untersuchen können, wird im vorliegenden Aufsatz der Diskurs um das Steuerzahlen in der Nachkriegszeit analysiert. Durch die Analyse von Zeitungsberichten und Parlamentsdebatten werden drei unterschiedliche, konkurrierende Narrative identifiziert, die geeignet waren, ganz verschiedene »policy windows« zu öffnen. Die historische Untersuchung zeigt, dass Narrative über das (ehrliche) Steuerzahlen immer mit bestimmten politischen Interessen verknüpft sind - und dass sie deshalb auch im aktuellen Diskurs über das (ehrliche) Steuerzahlen sorgfältig analysiert werden sollten. }},

  abstract     = {{Altruistically motivated investment has become the subject of economic, psychological and sociological research in recent years. The long tradition of ethical considerations concerning investment behavior has often been mentioned by historians but rarely investigated. This paper presents a case study of the 19th century philhellene banker Jean-Gabriel Eynard,
who was philanthropically active in Greece, but also invested part of his capital on the emerging Greek market. Drawing on the methodological approach of the “sociology of morality”, this article examines how Eynard invested in Greece, which norms and values concerning investment behavior he articulated and how far they were comparable with the norms and values of today’s Socially Responsible Investment. What emerges is that the practices and the norms of Socially
Responsible and Ethical Investment then and now are remarkably similar, while the “moral background” (G. Abend) has changed considerably in some, but not all points.}},

However, the attribution of importance and reputation to women’s intellectual achievements in this period is a case of its own. This paper investigates the methodical attempt of 18th century historiography, presenting the example of Jakob Brucker and his Pinacoteca to relocate intellectual women in his history of philosophy and science. The relative integration of women into the 18th century intellectual sphere is the starting point of this methodical investigation to retrace its ‘why and how’.

Da sich die aktuelle Diskussion auf die Perspektive der Systemtheorie beschränkt, ist es notwendig, die Verbindung auch aus der Perspektive Kritischer Theorie zu debattieren. Denn erst die Unterscheidung der heute immer mehr ins Gespräch kommenden Kritischen Systemtheorie von der kaum diskutierten Kritischen Theorie sozialer Systeme macht es möglich, die volle Produktivität der Theoriekollisionen zu erkennen. Wir konzipieren unsere Metareflexion damit als eine Intervention im Sinne einer soziologischen Selbstkritik.

  abstract     = {{Recent years have seen the emergence of physical products that are digitally networked with other products and with information systems to enable complex business scenarios in manufacturing, mobility, or healthcare. These “smart products”, which enable the co-creation of “smart service” that is based on monitoring, optimization, remote control, and autonomous adaptation of products, profoundly transform service systems into what we call “smart service systems”. In a multi-method study that includes conceptual research and qualitative data from in-depth interviews, we conceptualize “smart service” and “smart service systems” based on using smart products as boundary objects that integrate service consumers’ and service providers’ resources and activities. Smart products allow both actors to retrieve and to analyze aggregated field evidence and to adapt service systems based on contextual data. We discuss the implications that the introduction of smart service systems have for foundational concepts of service science and conclude that smart service systems are characterized by technology-mediated, continuous, and routinized interactions.}},
