Noch sieht die Realität allerdings anders aus. Wie Ehemalige sich zwischen familiären und beruflichen Optionen entschieden haben, welche Probleme sie zu bewältigen hatten und welche Lösungen sie fanden, davon berichten sie in unserem Titelthema. Jede dritte Akademikerin bleibt heute in Deutschland kinderlos, Tendenz steigend. Abgesehen davon, dass es auch schlichtweg Lebensentwürfe ohne Kinder gibt: Ein nicht unwesentlicher Grund dafür ist sicherlich, dass die größte Last bei der Kindererziehung immer noch Frauen tragen und sie deshalb auch die größeren Einbußen in ihrer Karriere haben. So herrscht bei vielen Arbeitgebern das Vorurteil, Mütter in Führungspositionen wären weniger leistungsfahig. Dass aber gerade eine Familie Frauen in verantwortungsvollen Positionen den Rücken stärken und zu noch größerem Einsatz beflügeln kann, davon berichtet der einführende Artikel. Ein Beispiel dafür, dass sich Familie und eine berufliche Führungsposition vereinbaren lassen, ist auch Uni-Präsidentin, Prof. Dr.-Ing. Dr. Sabine Kunst. In einem Interview verrät sie ihr ganz persönliches Erfolgsrezept und stellt außerdem die strategische Ausrichtung der Hochschule in den nächsten Jahren vor. Wenn Sie Ihre Erfahrungen zu unserem Titelthema mit anderen Ehemaligen diskutieren wollen, können Sie dies unter ,,Forum" in unserem "alumni-portal" tun. Wie immer freuen wir uns auf Ihre Meinung zur vorliegenden Ausgabe von ,,Portal alurnni" und wünschen Ihnen viele Vergnügen beim Lesen. Viele Grüße aus Potsdam Ihr Alumni-Team N2 - Dear readers, if the Federal Ministry for Family Affairs has its way, then Germany should become one ofthe most family friendly countries in Europe. However, today's reality shows a much different picture. ln our cover story, alumni report on how they have decided between familial and professional options as weil as on the problems solved along the way, and those yet to be mastered. One-third of all warnen with academic degrees do not have children. Not disregarding that there are paths in life which simply do not include having children, an important reason for this tendency lies without doubt in the fact that warnen still continue to carry the largest burden in the childrearing process, and that they therefore experience more serious Iosses regarding their professional careers than their male counterparts. For example, bias against mothers in leadership positions, due to their supposed reduced productivity, is still widely held by employers. The main article of our cover story shows that it is especially the family which can support warnen in positions of responsibility. The university's president, Prof Dr.-lng. Dr. Sabine Kunst, provides us with one prominent example of the compatibi/ity offamily and a professionalleadership position. ln an intenview she reveals her personal recipe for success - and discusses the strategic development of the university in the years to come. lf you would like to discuss your experiences regarding family and professional life with other alumni, please feel free to do so in the "forum" on our "alumni-portal". As always, we hope you enjoy reading this issue of the "Portal alumni" and appreciate your feedback.

The host rock to the PTBs is the so-called Jarna granite of quartz monzonitic to syenodioritic composition. The nearly 603m long BH-5 drill core from Hattberg, near the centre of the Siljan central uplift, contains numerous veins and pods of PTB. In particular, two major zones of 60m combined width contain extensive PTB network breccias (30% actual melt breccia component), with individual melt breccia occurrences up to >1m in length. Core logging and petrographic and geochemical analysis of the core have been performed, and the data are interpreted to suggest the following. (1) The impact event caused low to moderate (at essentially <20GPa) shock deformation in the host rock and in clasts of this lithology within the PTB. (2) Macroscopic deformation of the basement mainly comprises fracturing, with only localised cataclasis. (3) No evidence for shock melting (i.e. compression/decompression melting early in the cratering process) could be observed. (4) Optical and scanning electron microscopy showed that dark PTB contains a definite melt component. (5) Shearing has significantly affected this part of the central uplift, but its effects are limited to very short displacements and likely did not result in extensive melting. (6) A frictional heating component upon melt generation can, however, not be excluded, as many PTB samples contain clasts of a mafic (gabbroic) component, although only in one place along the entire core, a 1.2cm-wide section through such material in direct contact to host rock was observed. Consequently, we suggest that, upon uplift in the central part of the impact structure, considerable melt volumes were generated locally, especially in areas that had been affected by extensive cataclasis and where grain size comminution favoured melt formation. Rapid decompression related to central uplift formation is the preferred process for the generation of the PTB melt breccias.
