Wahlfach Lehramt Mathematik: Video-Lernzyklen für einen motivierenden Mathematikunterricht der Sekundarstufe 1
(Universität Kassel, 2024)
Das Projekt “Video-Lernzyklen für einen motivierenden Mathematikunterricht SEK 1“ ist ein Wahlfach im Lehramt Mathematik, in dem Studierende Video-Lernzyklen für den Einsatz in Unterricht und Lehre sowie als individuelle Lernunterstützung für Schüler*innen erstellen. Das Prinzip „Lesson Study“ wird umgesetzt. Unterstützt durch Expert*innen vertiefen sich die Video-Ersteller*innen in Themenbereiche, bereiten sie didaktisch und methodisch auf, geben gegenseitiges Feedforward.

Videos zu Theorie und Aufgaben zur höheren Mathematik Erklär- und Lernvideos zur höheren Mathematik für Ingenieurstudierende
(Universität Kassel, 2024)
Unter www.hm-kompakt.de ist eine Sammlung von ca. 800 meist maximal 10-minütigen.Videos zu Themen der höheren Mathematik verfügbar. Zum einen wird die Theorie erklärt, zum anderen gibt es ca. 400 Übungsaufgaben, deren Lösungen vorgestellt werden. In den Videos werden oft Geogebra-Visualisierungen genutzt, die auch als Download zur Verfügung stehen. Die Internet-Seite bietet eine übersichtliche Menü- und Navigationsstruktur. Zwei Bücher, auf denen die Inhalte beruhen, verweisen auf die Videos und bieten sich zum Nachlesen an.

The relationship between values and knowledge in visioning for landscape management: relevance for a collaborative approach
(2022-08-18)
Respecting connections between the diversity of values and forms of knowledge is essential to support a decision-making that fosters relationships between ecosystems and people. However, little theory has been developed for clarifying interactions between values and knowledge, and their relevance for environmental policy. We surfaced the overlooked relationship between values and knowledge by studying individual cognitive and emotional processes during a guided visioning exercise in the context of the multifunctional ...

Three-Dimensional Gradients of Cytokine Signaling between T Cells
(2015-04-29)
Immune responses are regulated by diffusible mediators, the cytokines, which act at sub-nanomolar concentrations. The spatial range of cytokine communication is a crucial, yet poorly understood, functional property. Both containment of cytokine action in narrow junctions between immune cells (immunological synapses) and global signaling throughout entire lymph nodes have been proposed, but the conditions under which they might occur are not clear. Here we analyze spatially three-dimensional reaction-diffusion models ...

Five priorities to advance transformative transdisciplinary research
(2024-03-21)
In response to the climate and biodiversity crisis, the number of transdisciplinary research projects in which researchers partner with sustainability initiatives to foster transformative change is increasing globally. To enable and catalyze substantial transformative change, transformative transdisciplinary research (TTDR) is urgently needed to provide knowledge and guidance for actions. We review prominent discussions on TTDR and draw on our experiences from research projects in the Global South and North. Drawing ...

Quantification of the In Vitro Predisposition to Glistening Formation in One Manufacturer’s Acrylic Intraocular Lenses Made in Different Decades
(2021-02-05)
Introduction
Foldable hydrophobic acrylic intraocular lenses (IOLs) are prone to develop a long-term postoperative material change called glistenings. The aim of this study was to investigate the changes in the predisposition for glistening formation in one type of hydrophobic acrylic IOL material from its introduction to the present day.
Methods
In a laboratory setup, an in vitro model was used to induce glistenings in hydrophobic acrylic IOLs manufactured by one company (Alcon, Fort Worth, TX, USA) in different ...

Lenticular Imaging: A New Experimental and Quantitative Analysis of Capsular Dynamics, “Choi-Apple View”
(2019-05)
Purpose: Development of a means for quantitative estimation of lenticular and zonular dynamics by using real-time imaging of human autopsy eyes during implantation of different intraocular lens (IOL) models.
Methods: Isolated lenticular structures from human autopsy eyes were prepared in vitro. The following IOLs were implanted: a one-piece C-loop haptic IOL, a three-piece C-loop haptic IOL, and a one-piece plate-type IOL. The amount of deformation of lenticular structures during implantation was calculated and ...

Propagation and branching strategies for job shop scheduling minimizing the weighted energy consumption
(2023)
We consider a job shop scheduling problem with time windows, flexible energy prices, and machines whose energy consumption depends on their operational state (offline, ramp-up, setup, processing, standby or ramp-down). The goal is to find a valid schedule that minimizes the overall energy cost. To solve this problem to optimality, we developed a branch-and-bound algorithm based on a time-indexed integer linear programming (ILP) formulation, which uses binary variables that describe blocks spanning multiple inactive ...

Identifying critical demand periods in capacity planning for networks including storage
(2023)
We consider a capacity planning problem for networks including storage. Given a graph and a time series of demands and supplies, we seek for integer link and storage capacities that permit a single commodity flow with valid storage in- and outtakes over all time steps. This problem arises, for example, in power systems planning, where storage can be used to buffer peaks of varying supplies and demands. For typical time series spanning a full year at hourly resolution, this leads to huge optimization models. To reduce ...
Dissertation
The Representation of Motion Events
(2022)
The thesis at hand approaches the conceptualization of motion events from a theoretical point of view as well as on the basis of a corpus study and two experimental designs. The research focuses on the investigation of different factors determining the conceptualization and verbalization of motion events by examining both cognitive variables and grammatical factors.
