Leaving the Street In Brief
This issue of P/PV In Brief focuses on Lauren J. Kotloff's recent report, Leaving the Street: Young Fathers Move from Hustling to Legitimate Work. Based on an in-depth interview study of participants in P/PVs Fathers at Work initiative, the report provides a rare glimpse inside the lives of young urban men with criminal records, exploring how they got involved with hustling, their experiences in the labor market and their feelings about fatherhood.Leaving the Street In Brief describes the four distinct groups that emerged in P/PVs study (the Reluctant Hustlers, the Ambitious Workers, the Reluctant Workers and the Committed Hustlers) and presents early findings from the Fathers at Work evaluation. It also touches on the full report's recommendations for programs serving young fathers
Flexibility of Various Nickel-Titanium Rotary Endodontic Files
Introduction: Nickel-titanium rotary files were originally developed to allow for greater flexibility when instrumenting root canals. The increased flexibility of nickel-titanium instruments allowed operators to negotiate canal curvatures with greater ease. File design is continually changing. Manufacturers are trying to produce files that will work more efficiently and safely. Knowing the properties of files marketed is especially important in helping to choose an appropriate file system. Current ISO standards require force measurements at a static point along the file. The purpose of this study was to evaluate the flexibility of four different nickel-titanium files at three different points along the file.
Materials and Methods: Flexibility of four different nickel-titanium rotary files (EndoSequence, ProFile, Vortex, and Vortex Blue) was measured. Each file was clamped at 3mm, 5mm, or 7mm (n = 10/length/file) and a universal testing machine was used to bend the files to a maximum deflection of 4.5mm. All data were statistically analyzed by two-way analysis of variance and post-hoc Tukey test (P = 0.05) to determine any significant differences.
Results: Statistically significant (P \u3c 0.05) differences were present. In general, ProFile was the stiffest, displaying the greatest force and bending moment values. Vortex Blue was significantly more flexible, with lower force needed for deflection and bending moments.
Conclusion: Vortex Blue files showed greater flexibility compared with the other nickel-titanium rotary files studied

Oyez! Oyez! Oyez! An Examination of the Centrality of the Supreme Court on the Legislative Process
While “it is emphatically the province and the duty of the judicial department to say what the law is” the duty to create the law rests with the legislature. The nature of the interaction between these two branches of the U.S. federal government is crucial to the application and functionality of U.S. public policy. My research seeks to establish the nature of this interaction by asking the questions: after the Supreme Court delivers decisions in a given year, is Congress more or less likely to address these same topics in the next Congressional session? And, does the tone of the next session’s legislation reflect agreement or disagreement with the Supreme Court’s holding?Governmen
