A researcher wants to investigate why some individuals released from prison on parole reoffend whereas others do not. As a starting point, the researcher considers the following probit model: Pr(??=1)=Φ(?0+?1??+?2ln??⁡+?3(??×ln??)), (2.1) where Φ denotes the standard normal cumulative distribution function, ln denotes the natural log and: ??=1 if paroled individual ? reoffends within three years of being paroled (0 otherwise); ??=1 if individual ? is male (0 otherwise); ?? is the number of years since individual ? was paroled. The...

When one works with parvoviruses, one notices that some particles have a positive DNA whereas others have a negative DNA. However all particles are equally infectious. What does it mean when DNA is positive or negative? You also observe that the following observations are perplexing: a) dsDNA isolated from cells never denatures irreversibly, that is, no ssDNA molecular species are recovered; b) DNA synthesis can proceed in-vitro in the absence of any primer. Explain the reason(s) for the anomalous behavior...
