Rhein-Main als polyzentrische Metropolregion: zur Geographie der Standortnetze von wissensintensiven Dienstleistungsunternehmen

Der Beitrag befasst sich mit strukturellen und funktionalen Aspekten polyzentrischer Strukturen in der Rhein-Main Region. Basierend auf laufenden Forschungsarbeiten des aus EU-Mitteln geförderten Projekts „Polynet“ wird die Metropolregion in sechs funktionale Stadtregionen (FURs) untergliedert. Anhand der Standortnetze regional ansässiger Unternehmen des wissensintensiven Dienstleistungssektors lassen sich in Anlehnung an die Methodologie des Globalization and World Cities Study Group and Network (GaWC) Konnektivitätsmuster der Verflechtungsintensität auf unterschiedlichen Maßstabsebenen ermitteln. Jede der sechs FURs verfügt über ein spezifisches nationales Konnektivitätsprofil mit anderen deutschen Städten. Innerhalb der Region hat die FUR Frankfurt eine führende Stellung und übernimmt aufgrund ihrer starken internationalen Verbindungen eine Gateway-Funktion. Wiesbaden, Mainz und Aschaffenburg besitzen ausgewogene Anbindungen auf nationaler Ebene, während im Falle von Darmstadt und Hanau regionale Schwerpunkte innerhalb Deutschlands hervortreten. In der Zusammenschau zeigt sich eine komplementäre Binnenstruktur der polyzentrisch organisierten Metropolregion Rhein-Main

Supplement 1 - SBFSEM step-by-step protocol from Three-dimensional reconstruction on cell level: case study elucidates the ultrastructure of the spinning apparatus of <i>Embia</i> sp. (Insecta: Embioptera)

Spinning is a phenomenon not only present in spiders, but also in many other arthropods. The functional morphology and complexity of spinning organs is often poorly understood. Their elements are minute and studying them poses substantial methodological difficulties. This study presents a three-dimensional reconstruction of a silk gland of <i>Embia</i> sp. on cellular level, based on serial sections acquired with serial block-face scanning electron microscopy (SBFSEM) to showcase the power of this method. Previous studies achieved either high resolution to elucidate the ultrastructure or satisfying three-dimensional representations. The high-resolution achieved by SBFSEM can be easily used to reconstruct the three-dimensional ultrastructural organization of cellular structures. The herein investigated spinning apparatus of Embioptera can be taken as an example demonstrating the potential of this method. It was possible to reconstruct a multinucleated silk gland containing 63 nuclei. We focused on the applicability of this method in the field of morphological research and provide a step-by-step guide to the methodology. This will help applying the method to other arthropod taxa and will help significantly in adapting the method to other animals, animal parts and tissues

Looking at the Laboratory Discussion: Course Modality Choice and Student Performance in Organic Chemistry

In the sciences, the laboratory is one of the most impactful spaces for student learning, engagement, and experience. Prior knowledge gleaned during lecture and laboratory discussion (i.e., a course section designed to further emphasize conceptual content underlying experiments and inform students about laboratory procedures or safety precautions) acts to supplement laboratory performance. With the recent increase in offering traditionally face-to-face courses in remote formats, many educators in the field of organic chemistry have opted to offer online laboratory discussion (LD) sections alongside more traditional face-to-face laboratory discussions. However, research on enrollment in laboratory discussions by modality, as well as their impact on subsequent course performance, is lacking. Conducting a logistic regression analysis, we found that females, students who identified as Black or African American, those with greater average ACT-SAT equivalency scores, and those students who completed organic chemistry LD online in the prior term all had greater odds of enrolling in an online organic chemistry LD course in subsequent academic terms. Additional hierarchical regression analyses indicated that many student- and academic-level factors were predictive of laboratory performance. Notably, when controlling student-level and academic-level characteristics, laboratory performance was higher for students who completed LD online compared to students who enrolled in face-to-face LDs. This study has important implications for students as they uptake courses in online settings and faculty as they decide what portions of their courses to offer remotely
