The Power Spectrum of Galaxy Density Fluctuations: Current Results and Improved Techniques

The power spectrum of density fluctuations measured from galaxy redshift surveys provides important constraints on models for the formation of large-scale structure. I review current results for the 3-D power spectrum and examine the limitations of current measurements and estimation techniques. To span the decade of wavelength between the scales probed by galaxy surveys and COBE, measure the detailed shape of the power spectrum, and accurately examine the dependence of clustering on galaxy species, we require deeper samples with carefully controlled selection criteria and improved techniques for power spectrum estimation. I describe a new method for estimating the power spectrum that optimally treats survey data with arbitrary geometry and sampling.Comment: 10 pages, uuencoded compressed postscript.

Keeping the Passion Alive: The Realities of Social Justice

In the following essay, a college student in a teacher education program discusses some of the realities in working for social justice as a future teacher. She shares her experiences both in her academic program, and in forming a student action group following a discussion and book seminar with author Jonathan Kozol. Teachers change lives. This is one of the reasons I chose to become one. Another reason I chose the teaching profession was due to my phenomenal experience in high school as a peer tutor in a life skills setting. Witnessing the growth of students through the course of a year and the changes their teacher made in their lives also changed mine and directly influenced my career aspirations. After this life-changing experience, I applied to Western Washington University due to their highly esteemed teacher preparation program and was admitted, thus beginning my professional development in the field of special education
