HIS – an international and digital summer school for STEM students

The teaching project HIS (Holistic International STEMs – Learning with case studies and real life industry experiences) is presented as part of the poster session. Experience shows that German (outgoing) and international (incoming) students have difficulties to communicate properly at the workplace in Germany as well as abroad due to language differences, especially in STEM terms. In addition, young professionals often do not have experience in working in international or virtual teams. All those challenges are current job requirements, not just in global companies. But: How to teach this in higher education? The classical formats of lectures or seminars are not suitable. Therefore, there is a need to develop and prove new teaching formats, within the curriculum as well as extracurricular. With focus on STEM subjects the presented project combines three current impacts on higher education: Internationalization, digitalization, and labor market orientation. The concept of the project is that STEM students from different countries will attend an international, virtual summer school (April to June 2016). They solve real-life job case studies together in small interdisciplinary teams. The participants are mentored by national and international industry partners and STEM professors. With such, the participants will improve language and communication skills, and apply and exchange their expertise as well as gain intercultural work experience. The concept was awarded by the “Stifterverband für die deutsche Wissenschaft” (Donors association for the promotion of humanities and sciences in Germany). The poster introduces the project and exemplary the three-dimensional assignments of one case study (occupational, lingual, and intercultural). At present, the project should be handled as a “project in progress”. Keywords: technology, teaching projects, STEM, internationalization, digitalization, labor market orientation, employability, job orientation, competencies, development of new curricul

Wozu noch ein E-Learning-Projekt?: Ein (selbst-)kritischer Beitrag zum Einsatz Neuer Medien an Hochschulen und zum Aufbau einer Koordinationsstelle E-Learning an der TU Bergakademie Freiberg

Der vorliegende Artikel diskutiert die aktuellen Erscheinungs- und Wirkformen Neuer Medien in der Hochschullehre und setzt sich kritisch, am Beispiel der TU Bergakademie Freiberg, damit auseinander, was E-Learning im akademischen Bereich ist/sein kann und vor allem, wo ein Einsatz nachhaltig und sinnvoll möglich ist

Neurodegenerative Diseases of the Retina and Potential for Protection and Recovery

Recent advances in our understanding of the mechanisms in the cascade of events resulting in retinal cell death in ocular pathologies like glaucoma, diabetic retinopathy and age-related macular degeneration led to the common descriptive term of neurodegenerative diseases of the retina. The final common pathophysiologic pathway of these diseases includes a particular form of metabolic stress, resulting in an insufficient supply of nutrients to the respective target structures (optic nerve head, retina). During metabolic stress, glutamate is released initiating the death of neurones containing ionotropic glutamate (N-methyl-D-aspartat, NMDA) receptors present on ganglion cells and a specific type of amacrine cells. Experimental studies demonstrate that several drugs reduce or prevent the death of retinal neurones deficient of nutrients. These agents generally block NMDA receptors to prevent the action of glutamate or halt the subsequent pathophysiologic cycle resulting in cell death. The major causes for cell death following activation of NMDA receptors are the influx of calcium and sodium into cells, the generation of free radicals linked to the formation of advanced glycation endproducts (AGEs) and/or advanced lipoxidation endproducts (ALEs) as well as defects in the mitochondrial respiratory chain. Substances preventing these cytotoxic events are considered to be potentially neuroprotective

Influence of External Magnetic Field on Dust−-Acoustic Waves in a Capacitive RF Discharge

This paper reports experiments on self$-$excited dust acoustic waves (DAWs) and its propagation characteristics in a magnetized rf discharge plasma. The DAWs are spontaneously excited in dusty plasma after adding more particles in the confining potential well and found to propagate in the direction of streaming ions. The spontaneous excitation of such low-frequency modes is possible due to the instabilities associated with streaming ions through the dust grain medium. The background E-field and neutral pressure determine the stability of excited DAWs. The characteristics of DAWs strongly depend on the strength of external magnetic field. The magnetic field of strength B $<$ 0.05 T only modifies the characteristics of propagating waves in dusty plasma at moderate power and pressure, P = 3.5 W and p = 27 Pa respectively. It is found that DAWs start to be damped with increasing the magnetic field beyond B $>$ 0.05 T and get completely damped at higher magnetic field B $\sim$ 0.13 T. After lowering the power and pressure to 3 W and 23 Pa respectively, the excited DAWs in the absence of B are slightly unstable. In this case, the magnetic field only stabilizes and modifies the propagation characteristics of DAWs while the strength of B is increased up to 0.1 T or even higher. The modification of the sheath electric field where particles are confined in the presence of the external magnetic field is the main cause of the modification and damping of the DAWs in a magnetized rf discharge plasma.Comment: 9,

Studium Generale oder Wissen, das sich lohnt: Ein Werkstattbericht über den Einsatz des E-Portfolios zur Anerkennung außer- und überfachlicher Studienleistungen

Gemeinsam mit der Hochschule Mittweida initiierte die TU Bergakademie Freiberg im Jahr 2013 eine Machbarkeitsuntersuchung zum Ausbau über- und außerfachlicher Bildungsangebote. Im Vordergrund standen zwei zentrale Fragestellungen: 1. Wie kann die Persönlichkeits- und Kompetenzentwicklung von Studierenden in Bezug auf die Wahrnehmung außer- und überfachlicher Bildungsangebote über die gesamte Studienzeit dokumentiert, anerkannt und präsentiert werden? 2. Wie kann das im Lernmanagementsystem OPAL integrierte Werkzeug E-Portfolio hierfür angepasst und eingesetzt werden? Im folgenden Beitrag werden Ausgangslage und ausgewählte Ergebnisse der Machbarkeitsuntersuchung in Bezug auf die TU Bergakademie Freiberg vorgestellt. Im Fokus steht ein spezifisches Anerkennungsmodell, dessen praktische Umsetzbarkeit aktuell in einem Pilotkurs erprobt wird. In Anlehnung an den zugehörigen Kurzworkshop auf dem HDS.Forum 2014 ist der vorliegende Artikel als Werkstattbericht und Impuls zur weiteren hochschulübergreifenden Diskussion anzusehen..
