    Throughout my years at La Salle University as a dual Psychology and Criminal Justice major, I have had the opportunity to study and learn about a variety of different topics regarding these two fields. The specific field that I was drawn towards the most was the field of forensic psychology, which is why it is the topic of my research project. My project’s main goal is to ensure that forensic psychology, with some new improvements, continue to be a leading force in both the field of criminal justice and psychology. Specifically, my project focuses on the future of forensic psychology by analyzing the strengths and weaknesses of the field. Issues such as eyewitness testimony and the disagreement between forensic psychologists have affected the reliability of the field, whereas the mistreatment of trans individuals and labeling have negatively impacted individuals in the criminal justice system (CJS). These are just a few of the issues that will be covered in this paper, and all of these issues play a hand in preventing the field from being as effective as it should be

    The Distribution of X-ray Dips with Orbital Phase in Cygnus X-1

    We present results of a comprehensive study of the distribution of absorption dips with orbital phase in Cygnus X-1. Firstly, the distribution was obtained using archival data from all major X-ray observatories and corrected for the selection effect that phase zero (superior conjunction of the black hole) has been preferentially observed. Dip occurrence was seen to vary strongly with orbital phase \phi, with a peak at \phi ~ 0.95, i.e. was not symmetric about phase zero. Secondly, the RXTE ASM has provided continuous coverage of the Low State of Cygnus X-1 since Sept. 1996, and we have selected dip data based on increases in hardness ratio. The distribution, with much increased numbers of dip events, confirms that the peak is at \phi ~ 0.95, and we report the discovery of a second peak at \phi ~ 0.6. We attribute this peak to absorption in an accretion stream from the companion star HDE 226868. We have estimated the ionization parameter at different positions showing that radiative acceleration of the wind is suppressed by photoionization in particular regions in the binary system. To obtain the variation of column density with phase, we make estimates of neutral wind density for the extreme cases that acceleration of the wind is totally suppressed, or not suppressed at all. An accurate description will lie between these extremes. In each case, a strong variation of column density with orbital phase resulted, similar to the variation of dip occurrence. This provides evidence that formation of the blobs in the wind which lead to absorption dips depends on the density of the neutral component in the wind, suggesting possible mechanisms for blob growth.Comment: 9 pages, Latex, 7 ps figures. accepted by MNRA

    Santillo, N., Figueroa, M., Lasala, T., Manning, J., William Paterson University, Wayne NJ Purpose: The purpose of this study was to determine if changes occurred in the ventilatory threshold (VT) upon manipulation of body weight (BW) when comparing 80% to 100% of BW in healthy college aged individuals on the Alter-G® anti-gravity treadmill. Methods: A modified Bruce Protocol was used to measure oxygen consumption (VO2peak) on 10 subjects (5 males, 5 females) at 100%, and 80% of BW. Testing protocols were randomized with two weeks in between each test. VT was determined by the software algorithm in the MedGraphics Ultima Series (St. Paul, MN) open exchange spirometer. Results: Gender did not significantly affect relative VO2peak or VT at either percentage of BW. No significant differences were found with regards to VO2peak (ml×kg-1×min-1) or VT at 100%BW & 80% BW. Conclusion: Upon the unweighting of a subject on the Alter-G® anti-gravity treadmill, individuals are able to train at similar intensities at 80% and 100% of BW. Since the unweighting produced similar metabolic responses, one could suggest that those with orthopedic limitations, who are not fully weight bearing, can maintain their cardiovascular conditioning. This type of training may also be advantageous for athletes who wish to reduce musculoskeletal strain within their training
