Introducing the Handbook of Social Protection Systems
No full textSocial protection has been increasingly recognized by experts from different fields as a key instrument for social, economic, political, and environmental development. It is also known for tackling multiple goals related to the reduction of risk, poverty and inequality at once. Yet, its instruments are often seen in isolation, programmes are still managed in silos and the systemic aspect is often overlooked. Engaging in critical discussions about the systemic aspect of social protection and outlining what it really takes to pursue a systemic approach has motivated the two editors, Prof. Dr. Esther Schüring from H-BRS and Dr. Markus Loewe from the German Institute of Development and Sustainability (IDOS) to launch the very first Handbook on Social Protection Systems in late 2021
Mediologische Experimentalsysteme. Zu einer kriminalästhetischen Anordnung
No full textDie folgenden Überlegungen versuchen einerseits, die Arbeit an einer ins besondere medienwissenschaftlich fundierten Auslegung der sogenannten Kriminalliteratur1 weiter zu denken und in den Zusammenhang einer Lektüre zu stellen, die das Dispositiv ›Literatur und ihre Medien‹ als Bezugnahme bzw. Verhältnismäßigkeit versteht: als »Verhältnis der Literatur zu ihren Medien« und/oder als »Verhältnis der Medien zur Literatur«.
Modeling of Creep Behavior of Particulate Composites with Focus on Interfacial Adhesion Effect
No full textEvaluation of creep compliance of particulate composites using empirical models always provides parameters depending on initial stress and material composition. The effort spent to connect model parameters with physical properties has not resulted in success yet. Further, during the creep, delamination between matrix and filler may occur depending on time and initial stress, reducing an interface adhesion and load transfer to filler particles. In this paper, the creep compliance curves of glass beads reinforced poly(butylene terephthalate) composites were fitted with Burgers and Findley models providing different sets of time-dependent model parameters for each initial stress. Despite the finding that the Findley model performs well in a primary creep, the Burgers model is more suitable if secondary creep comes into play; they allow only for a qualitative prediction of creep behavior because the interface adhesion and its time dependency is an implicit, hidden parameter. As Young’s modulus is a parameter of these models (and the majority of other creep models), it was selected to be introduced as a filler content-dependent parameter with the help of the cube in cube elementary volume approach of Paul. The analysis led to the time-dependent creep compliance that depends only on the time-dependent creep of the matrix and the normalized particle distance (or the filler volume content), and it allowed accounting for the adhesion effect. Comparison with the experimental data confirmed that the elementary volume-based creep compliance function can be used to predict the realistic creep behavior of particulate composites
Solving Stationary Gas Transport Problems with Compressors of Piston and Generic Type
No full textIn this paper, modeling of piston and generic type gas compressors for a globally convergent algorithm for solving stationary gas transport problems is carried out. A theoretical analysis of the simulation stability, its practical implementation and verification of convergence on a realistic gas network have been carried out. The relevance of the paper for the topics of the conference is defined by a significance of gas transport networks as an advanced application of simulation and modeling, including the development of novel mathematical and numerical algorithms and methods
Harald Schmidt: Zur Ästhetik und Praxis des Populären
No full textAls Medien- und insbesondere Fernsehphänomen hat Harald Schmidt die TV-Kultur im deutschsprachigen Raum maßgeblich beeinflusst. So ist es etwa der Harald Schmidt Show gelungen, halbironische Sprechweisen diskursfähig zu machen, die sich bis in die Gegenwart der Social Media verfolgen lassen. Die Beiträger*innen des Bandes untersuchen vor diesem Hintergrund die »Methode Harald Schmidt«, d.h. die Unterminierung gängiger sozialer Vorstellungen bei gleichzeitiger Affirmation derselben. Die zentrale These lautet: Harald Schmidt hat grundlegende Voraussetzungen dafür geschaffen, eine weitestgehend neue Populärkultur ästhetisch wie kulturpraktisch zu etablieren
