From Bison to Cattle: The Ecology of the Southern Plains 1500-1750

Bison made their home on the Southern Plains for millennia. However, their migratory patterns began to shift in the 17th and 18th centuries. My research investigated what caused this drastic shift and how it had far reaching effects on the ecology of the Southern Plains. Using archives from two prominent Catholic priests, I began to piece together why the bison left the Southern Plains. Rather than focus on the Europeans as the main players, I instead focused on the Indigenous peoples, the animals, and the land as the centralized actors in this project. I discovered that the introduction of cattle by the Spanish missions was the leading factor. As the cattle quickly consumed the resources, the bison had to find additional inhabitable spaces. Their swift departure from the Southern Plains resulted in upheaval for the Indigenous inhabitants and the ecology of the Plains themselves

On the investigations of galaxy redshift periodicity

In this article we present a historical review of study of the redshift periodicity of galaxies, starting from the first works performed in the seventies of the twentieth century until the present day. We discuss the observational data and methods used, showing in which cases the discretization of redshifts was observed. We conclude that galaxy redshift periodisation is an effect which can really exist. We also discussed the redshift discretization in two different structures: the Local Group of galaxies and the Hercules Supercluster. Contrary to the previous studies we consider all galaxies which can be regarded as a structure member disregarding the accuracy of velocity measurements. We applied the power spectrum analysis using the Hann function for weighting, together with the jackknife error estimator. In both the structures we found weak effects of redshift periodisation.Comment: 10 pages, 4 figures, to be published in Part. and Nucl. Lett. 200

Results from computer program for analyzing scattered light suppression systems for large space telescope

A computer program was developed which has the ability to analyze the performance of most light suppression systems so as to predict the amount of scattered light which will reach the image plane for various conditions of unwanted light input from the sun, earth, or moon. This program was used to analyze three different configurations of the large space telescope (LST): an LST with a truncated sunshield, an LST with an extended cylindrical sunshield, and an LST with a conical sunshield which is tilted upwards. The computer program gives the user detailed information as to the paths taken by the unwanted stray light to reach the image plane, and pinpoints those portions of the light suppression system which contribute most of the stray light, so that areas requiring improvements are evident. Certain design guide lines were formulated for any light suppression system selected for the LST, and one which meets these requirements (the tilted sunshade) is described in detail

Properties of the redshift

Central to any analysis of dynamical systems, or large scale motion, is the interpretation of redshifts of galaxies as classical Doppler velocity shifts. This is a testable assumption and for many years evidence has accumulated that is inconsistent with the assumption. Here, the authors review recent evidence suggesting systematic radial dependence and temporal variation of redshifts

Raising Awareness of Compassion Fatigue Among Healthcare Providers in the Coronary Care Unit

Compassion fatigue is a pressing issue in critical care units across the healthcare field. There is a sincere desire by nurses to give the best care possible to each of their patients; however, many obligations split the nurse’s attention so they do not feel as if they are providing the best care to their patients. When nurses stop viewing their patients as humans and start viewing them as tasks, the compassion that the nursing profession prides itself on, is no longer there to the degree that is needed for quality care. Increasing awareness of compassion fatigue and teaching nurses and staff how to identify and combat this is imperative to the future of nursing. The purpose of this scholarly project was to raise awareness of compassion fatigue among healthcare clinicians in the CCU setting of a community-based hospital and to provide them with strategies and interventions that can be utilized to combat this pressing phenomena of interest. This scholarly project evaluated existing knowledge surrounding compassion fatigue in a pre-test and a ProQol 5 pre-survey. An educational intervention was conducted to educate staff on compassion fatigue. Two weeks later a post-test and ProQol 5 post-survey was given to determine if there was any improvement in the compassion fatigue scores after the educational intervention. The results showed no statistical difference between the pre- and post-test or the ProQol 5 pre- and post-surveys
