New g'r'i'z' Photometry of the NGC 5128 Globular Cluster System

We present new photometry for 323 of the globular clusters in NGC 5128 (Centaurus A), measured for the first time in the $g'r'i'z'$ filter system. The color indices are calibrated directly to standard stars in the $g'r'i'z'$ system and are used to establish the fiducial mean colors for the blue and red (low and high metallicity) globular cluster sequences. We also use spectroscopically measured abundances to establish the conversion between the most metallicity-sensitive colors ($(g'-r')_0$, $(g'-i')_0$) and metallicity, [Fe/H].Comment: 14 pages, 9 figures, accepted in A

Maintaining the Human Touch in Educational Leadership

It is a pleasure to be invited to contribute to this special edition of the TCPEA School Leadership Review. TCPEA has been a valuable organization for me as the relationships that have been fostered through it have enabled me to grow personally and professionally. This has led me to consider some of the issues that educational leaders are facing today and will continue to face in the years to come which are focused on the notion of how to effectively maintain human relationships. While few leaders agree on everything, there is no doubt that we all agree this is a complex time for our schools. My focus of this article is to consider three of the challenges before us to maintain the human touch in our profession: Identifying appropriate responses to the dilemmas that are occurring due to technology advances which include movement to hybrid/blended and fully on-line teaching venues, Establishing covenant communities in our diverse classrooms and beyond, and Nurturing our professional relationships as educational leaders. While these three topics might seem unrelated, I believe they all are connected to our shared humanity and all have the potential to develop or diminish the human touch
