WORKSHOP
on leadership skills
When: 5. - 6.12.2019
Where: Bremen city center
Schedule:
Day 1: 09:30-16:00 (including 1h lunch)
Day 2: 09:30-13:00
Participation in both days is required.
This workshop is organised jointly with the CRC "Global Social Policy Dynamics".
Workshop Description "Leadership Skills for Women Team Leaders"
Have you ever struggled with a team member, who doesn’t seem motivated? Do you sometimes wonder how to lead without formal authority? Or do you feel “stuck in the middle” between your boss and the team you are leading as a postdoc?
Leading teams in the academic context is a challenging task. It can be inspiring and stressful at times. Some insights into communication and leadership skills can make a difference, for you personally and for your team.
This one and a half day training was designed to support those inprospective leadership positions with some insights and helpful leadership approaches to expand their skill set and gain suggestions for concrete situations at hand. Some of the topics that will be covered are:
- Understanding structural aspects of leading from a “sandwich” position
- Defining and clarifying one’s role and mandate as well as expectations
- Leadership styles and Situational Leadership
- Understanding social systems and team-development
- Building a network and support system
- Handling tricky situations from real life examples
The training will consist of short inputs, lots of practical exercises and experience sharing. We strongly recommend that participants come prepared with some real life situations and questions that will serve as a basis for practice and discussions.
Trainer:
Dr. Anette Hammerschmidt is a trainer and coach in the academic field as well as in the business world with over 20 years of experience. Her main expertise lies in leadership topics as well as organizational and team-development, intercultural cooperation and self-leadership.

Astronomie am Fallturm
Where: ZARM, University of Bremen
Where: | ZARM, University of Bremen |
Speaker: | Dr. Tobias Illenseer, Universität Kiel |
Title: | Der Einfluss von Selbstgravitation auf das Wachstum supermassereicher Schwarzer Löcher |
Abstract: | |
Speaker: | Dr.-Ing. Silvia Scheithauer, Max-Planck-Institut für Astronomie (MPIA), Heidelberg |
Title: | Gravity CIAO - Instrumentierung am ESO Paranal Observatorium |
Abstract: | Die ESO (European Southern Observatory) betreibt mehrere astronomische Observatorien in Chile, unter anderem das Very Large Telescope Interferometer (VLTI) auf dem Cerro Paranal. Die 14 ESO Mitgliedsstaaten - unter anderem Deutschland - sind für den Bau der astronomischen Instrumente zuständig. Seit 2015 wird dort das GRAVITY Instrument in Betrieb genommen: GRAVITY ist ein Nah-Infrarot-Instrument der zweiten Generation für das VLTI, welches das Licht der vier 8,2m-Teleskope miteinander kombiniert, um eine viel höhere Auflösung zu erreichen, als es mit einem einzigen Teleskop möglich wäre. Im Zentrum nahezu jeder größeren Galaxie finden wir supermassereiche Schwarze Löcher mit Massen von bis zu einigen 1010 Sonnenmassen. Wir gehen heutzutage davon aus, dass diese Schwarzen Löcher wie auch die sie umgebenden Galaxien eine kosmologische Entwicklung durchlaufen. Das bedeutet, dass große, massereiche Strukturen nicht einfach plötzlich nach dem Urknall vorhanden sind, sondern im frühen Universum entstehen und dann durch das Ansammeln von Materie (Akkretion) wachsen. Im Falle der supermassereichen Schwarzen Löcher ist dieser Akkretionsprozess direkt beobachtbar und steht im engen Zusammenhang mit dem Phänomen der Quasare und aktiven Galaxien. Der Vortrag wird einen allgemeinen Einblick in das Gebiet der Akkretionsphysik sowie der theoretischen Behandlung und numerischen Simulation sogenannter Akkretionsscheiben geben. Im Fokus stehen dabei Systeme, bei denen die Masse des zentralen Schwarzen Lochs deutlich geringer ist als die der sie umgebenden Materie. Es wird diskutiert inwieweit sich diese Systeme von den klassischen, nicht-selbstgravitierenden Modellen für Akkretionsscheiben unterscheiden. Dabei wird insbesondere die Frage erörtert, ob Modelle für selbstgravitierende Akkretionsscheiben das beobachtete Wachstumsverhalten von upermassereichen Schwarzen Löchern erklären können. |
